Gazoo Racing will enter the DKR GR FC Hilux, a fuel cell electric vehicle (FCEV), in the 2027 Dakar Rally.

The project represents a new challenge to demonstrate hydrogen fuel cell technology in the demanding conditions of the Dakar Rally. Based on the DKR GR Hilux, the DKR GR FC Hilux replaces its gasoline engine with Toyota’s fuel cell system. It emits no CO2 while driving, with water as its only tailpipe emission.

The Dakar Rally’s high temperatures, rough terrain and long stages make it a demanding test environment for hydrogen fuel cell technology. Toyota said that the project will focus on fuel cell downsizing, cooling performance, durability and energy management.

Lessons learned from developing and operating the DKR GR FC Hilux will contribute to the wider application of fuel cell technology in passenger cars, trucks, buses, trains, marine applications, race cars and stationary power generators. Engineers involved in the project also hope to develop problem-solving skills through hands-on, on-site experience.

Testing and tuning of the FCEV powertrain and its software, together with vehicle build-up, have begun in Belgium. A test program will be conducted progressively in the coming months.

The Dakar Rally will be held in Saudi Arabia from January 1 to January 15, 2027, with King Abdullah Economic City serving as the starting and finishing point.

The DKR GR FC Hilux will compete in the Dakar Future Mission 1000 category, which is dedicated to experimental vehicles and the demonstration of new technologies. The category follows a unique competitive format, with crews of drivers and navigators racing against the clock over 13 stages comprising a total of 1,000 competitive kilometers.

Hydrogen in motorsports

Toyota’s efforts to use hydrogen-related technologies in motorsports began in 2021, when Rookie Racing entered the Japanese Super Taikyu series with the hydrogen-engined ORC Rookie Corolla H2 Concept.

In rallying, the potential of hydrogen engines was demonstrated in 2022, when the GR Yaris H2 completed demonstration runs at the Ypres Rally in Belgium, a round of the FIA World Rally Championship. Further development was showcased through demonstration runs by the GR Yaris Rally2 H2 Concept at Rally Finland in 2025 and Rallye Monte-Carlo in 2026.

In the 2024 Dakar Rally, HySE-X1, a hydrogen-engine buggy, completed the Dakar Future Mission 1000, followed in 2025 by the evolved HySE-X2. Both vehicles were entered by HySE (Hydrogen Small mobility & Engine technology Association), a technical research association in which Toyota Motor Corporation participates.

In circuit racing, the 2026 24 Hours of Le Mans – a round of the FIA World Endurance Championship – featured demonstration laps by the TR LH2 Racing Prototype, which is powered by a liquid-hydrogen engine and based on the TR010 Hybrid race car. In addition, a hydrogen-engined GR Corolla equipped with superconducting technology became the first vehicle of its kind in the world to complete a race in the 2026 Super Taikyu series.

The 2027 Dakar Future Mission 1000 will be the first time Toyota has combined hydrogen and fuel cell technology in its motorsport activities.

In recent news, McLaren 788HS debuts as final chapter of 720S supercar series 

The post Toyota Gazoo Racing to enter hydrogen fuel cell Hilux in 2027 Dakar Rally appeared first on Professional Motorsport World.

The final model in the supercar lineage that began with the 720S (2017) and continued through the 765LT and 750S, the 788HS is the third McLaren to carry the High Sport designation, following the 2012 MP4-12C HS and 2016 MSO HS.

The 788HS uses a 788ps (777bhp) 4.0-liter twin-turbo V8 and has a 1,265kg dry weight, to deliver a power-to-weight ratio of 623ps per metric ton —the highest in the 720S/750S/765LT series. The car features a bespoke aerodynamic package and updated exterior design and personalization options offered through McLaren Special Operations (MSO).

“The new McLaren 788HS has been designed and engineered with a singular focus; to deliver a visceral experience and captivating drive through its precise balance of performance, sound, dynamism and individuality,” said Henrik Wilhelmsmeyer, chief commercial officer, McLaren Automotive.

“It represents the ultimate expression of our supercar series that began with the 720S and becomes only the third McLaren to wear our HS designation – a fitting finale for a much loved and critically acclaimed car.”

Assertive design 

The McLaren 788HS features what the company says is the most advanced aerodynamic package ever applied to the platform, increasing downforce by 10% over the 765LT, with “uncompromized vehicle dynamics and balance”.

The aerodynamic concept centers on an S-Duct hood, a raised active rear spoiler and an intricate Formula 1-inspired rear diffuser. Working in combination with a bespoke front splitter, these elements enhance stability, performance and driver confidence. The louvred under-wing panel further supports powertrain cooling and aerodynamic efficiency.

The driver-centric cabin layout includes a lightweight carbon-fiber center console that signifies the level of focus applied to every aspect of 788HS. The cabin also features bespoke HS branding with a unique perforation pattern for the upholstery and a dedication plaque.

Track precision meets on-road engagement

The heart of the 788HS is McLaren’s M840T 4.0-liter twin-turbo V8, which revs to 8,500rpm and develops peak power at 7,500rpm. With 800Nm of torque, it delivers immediate response and sustained acceleration – from 0-100km/h in 2.8 seconds and 0-200km/h in 7.0 seconds, and to a top speed of 330km/h (205mph). A unique engine mount calibration for 788HS delivers heightened engagement and connection between powertrain and driver without compromising long-distance usability.

The Proactive Chassis Control III linked-hydraulic suspension system with bespoke suspension tuning delivers even higher levels of dynamic performance. The 788HS also features a 5mm lower front ride height than the 750S, for a more dynamic and engaging driving experience.

Braking performance is enhanced through carbon ceramic discs derived from the McLaren Senna, with black six-piston forged aluminum monoblock front calipers and integrated cooling for sustained high-performance use. The 788HS also introduces the first center-lock wheel mechanism ever fitted to this supercar series, in combination with a new Super Lightweight Forged Alloy wheel.

The 788HS uses a quad-exit titanium exhaust system, which McLaren says increases exhaust intensity across the rev range, along with induction and exhaust sound symposer technology designed to enhance the V8’s engine note inside the cabin.

The post McLaren 788HS debuts as final chapter of 720S supercar series appeared first on Professional Motorsport World.

German manufacturer RUF Automobile has debuted a new prototype eight-cylinder boxer engine at the 2026 Goodwood Festival of Speed.

Housed in a mule car based on the company’s CTR3 mid-engine chassis, known internally as the Erprober (German for ‘tester’), the in-house-developed 4.8-liter twin-turbocharged unit produces over 1,000hp and 1,000Nm of torque. The car will appear in the Supercar Run twice daily from Friday, July 10, through Sunday, July 12, driven by Tanner Foust, and will be on static display in the Supercar Paddock across the event.

The B8 is a development testbed rather than a production model, evaluating technologies intended for a future RUF vehicle. Development has involved extensive testing across thousands of kilometers, with lubricant partner Motul supporting the program through its range of high-performance lubricants.

“There are moments in a company’s history that define the future,” said company co-owner Alois Ruf. “For RUF, the boxer-eight is one of those moments. A boxer-eight has never been part of our story, or anyone else’s in this form, so we decided to write a new chapter in automotive history. We look forward to letting the engine speak for itself at Goodwood.”

The chassis required stretching by 100mm to accommodate the extra cylinder pair, which drives through a RUF 6-speed manual transmission. The CTR3 was chosen as the test platform to enable the engine’s performance to be evaluated in a high-performance environment while the program remained low-profile.

Though unable to delve into great detail – it is still early days for the project – RUF chief engineer Marc Brunner explained to APTI, “I think the idea has been brewing for many years in the head of Alois Ruf. We’ve always loved the boxer engine, the boxer-six. It’s in our DNA, it’s in our passion. You want to go bigger? Well, just add more cylinders, so we thought let’s go for it. It’s an emotional project, it’s a passion project, and we’re happy that we have an engine running that we can actually run tests and further develop.”

Though unable to provide many insights, Brunner did reveal that the architecture of the engine (which uses a cast rather than a billet crankcase) was based on the company’s CTR Anniversary engine, which was inspired in turn by the Porsche Metzger engines. “For this project we took that and expanded to eight cylinders,” he says. There were some challenges with the extended crankshaft but “we worked with our supplier to get the best of both worlds; we are familiar with the boxer structure and they’re familiar with crankshafts.”

The CTR3 test vehicle running at Goodwood features a bespoke livery created in collaboration with Aloisa Ruf and Optima Batteries, drawing on the yellow associated with the original CTR Yellowbird. The flowing graphic design incorporates the number eight, referencing the B8 designation.

The debut of the new Grecale, GranTurismo and GranCabrio is the result of a strategic update aimed at strengthening the Maerati’s position in the luxury segment, where design, elegance, performance, craftsmanship and a human-centric approach to technology all contribute to the same idea, the auto maker said.

Santo Ficili, Alfa Romeo CEO and Maserati COO, explained, “For over 112 years, we have interpreted contemporary luxury in a distinctive way and aim to grow further in this segment, expanding our product offering and investing in the technologies that best express its character: from the development of iconic powertrains such as the V6 Nettuno to the evolution of the performance of the Folgore range, with a technological strategy aligned with the expectations of our customers.”

The GranTurismo and GranCabrio

The latest GranTurismo coupe and GranCabrio convertible feature a new calibration of the engine and transmission, making the car more responsive and rewarding, while the acoustic character has been refined with an iconic and engaging exhaust sound.

Described as “heirs to the captivating Maserati GranTurismo of the past”, which was launched in 2007 and renewed in 2022 and 2023 respectively, the GranTurismo and GranCabrio are now presented with refinements spanning design and driving dynamics.

Both models are available in three versions. Two ICE options are the entry-level 483hp version, which interprets “the luxury of travel” and the 582hp Trofeo, which is said to heighten sporting character.

The GranTurismo and GranCabrio Trofeo represent the most powerful expression of the range. At their heart is the V6 Nettuno, with motorsport-derived pre-chamber combustion technology, now raised to 582hp (40hp more than the previous generation). Both models feature a 3.0-liter twin-turbo engine that shares with the MCPURA the patented Formula 1-derived MTC technology, with cylinder deactivation for efficiency and a front differential aligned with the engine to lower the center of gravity.

The combustion-engine models offer three drive modes: GT, Sport and Country on the 482hp version, with Corsa mode reserved for the Trofeo. Country mode, also available on the EV Folgore, raises the ride height by 20mm. Sport mode enhances exhaust sound and suspension response, and is also available on the Trofeo.

The Folgore, with 751hp and torque vectoring, brings the family into the electric era. The BEV’s 800V system uses three motors, one at the front and two decoupled motors at the rear, for more than 1,200 hp installed and 760 hp continuously delivered to the wheels. The two rear motors enable surgically precise torque vectoring, while the 92.5kWh battery adopts a T-bone geometry that keeps the height at just 1,353mm, the lowest among electric cars. AWD Disconnect is standard, transferring drive to the rear axle in 500 milliseconds through the physical disengagement of the front half-shafts. A new energy management algorithm brings the GranTurismo Folgore range to more than 540km.

The Grecale

Maserati’s luxury D-SUV, the Grecale, combines spaciousness, sporty performance and everyday practicality. Its cabin features premium materials and high levels of comfort, while selectable drive modes adapt the driving experience to different conditions and preferences. At the top of the range, a V6 twin-turbo engine delivers class-leading specific output, which is also complemented by a distinctive exhaust note and Formula 1-inspired technology.

The post Maserati unveils updated Grecale, GranTurismo and GranCabrio appeared first on Professional Motorsport World.

Speaking at the world premiere of the new M Concept Neue Klasse at the 24 Hours of Le Mans last week, Oliver Heilmer, head of design for BMW Compact Class, Neue Klasse and BMW M said, “The new BMW M design language forms the expressive spearhead of the Neue Klasse – determined and purposeful. At BMW M, form consistently follows function. Every detail serves performance. This project is truly special to me because it carries the BMW M character into a new era.”

Form, function and motorsport references

Numerous M-specific design measures have been implemented to optimize aerodynamics – including the reinterpreted M aero exterior mirrors in the colors of BMW M. A distinctive air outlet shapes the V-shaped hood and supports the cooling of the electric drivetrain.

The BMW M Concept Neue Klasse is characterized by a forward-facing shark nose and a light signature with a depth effect, with the headlights and kidney grille integrated into a single unit.

New M yellow lights, inspired by GT racing cars and the BMW M Hybrid V8, are intended to become a signature feature of future BMW M models. Three-dimensional track lights add another lighting accent to the outer sections of the front apron.

The trimaran-style front bumper provides structural support for the front splitter. At the rear, the track lights and trimaran design continue above the floating diffuser. A ducktail spoiler is designed to improve aerodynamics and increase rear-axle downforce.

Natural-fiber elements are used in the exterior and interior of the vehicle.

High performance and BMW M driving experience

The BMW M Concept Neue Klasse represents the next chapter in the M-typical blend of dynamics, agility and precision.

“Even in the new all-electric era, we continue the M-typical tradition of transferring both technological innovations and defining design features directly from motorsport into series production,” said Franciscus van Meel, chairman of the board of management at BMW M.

BMW M eDrive is based on the Neue Klasse’s Gen6 technology and was developed specifically for all-electric BMW M automobiles. The drivetrain concept combines four electric motors with the central control software BMW M Dynamic Performance Control in the Heart of Joy high-performance computer. Thanks to the integrated, wheel-specific control of the drivetrain and braking systems, BMW M eDrive opens up new potential for driving dynamics and driving safety. It enables high recuperation performance, optimal traction right up to the limit, and particularly direct response.

The 800V technology and the high-voltage battery with an energy content of more than 100kWh create the conditions for long-range capability. A BMW M-specific optimized version of sixth-generation cylindrical cells provides particularly high output when delivering energy to the electric motors and during charging. The housing of the high-voltage battery is structurally integrated with the front and rear axles to improve the driving dynamics.

Force Technology is manufacturing valve springs for global engine designer and manufacturer Cosworth to use in the next generation of hypercars.

The company employs 50 specialist staff and sells its precision valve springs to customers worldwide. Managing director Steve Williams explained, “Every valve spring we produce is fully bespoke to the customer’s application. Development programs can take many months – and in some cases several years – as we work closely with customer design engineers to optimize spring performance using advanced engineering tools such as finite element analysis (FEA).

“Once a design is established, the springs progress through a rigorous multistage sampling and validation program. This ensures both manufacturing quality and in-engine performance, with extensive durability and functional testing carried out before production approval.

“In a modern high-speed engine, the valve spring plays a critical role in controlling the movement of the valvetrain under extreme forces and dynamic vibration. At very high engine speeds, maintaining precise valve control is essential to ensure efficient combustion, maximum performance and long-term reliability. Our challenge is to engineer valve springs capable of controlling and damping these forces in some of the world’s most demanding operating conditions.”

Williams noted that Force Technology sources only premium-grade spring wire for its spring valves, because microscopic material defects can have a significant impact on fatigue life and may result in catastrophic engine failure. Manufacturing a high-performance spring valve potentially involves more than 20 production stages.

Every completed spring batch passes through a comprehensive final inspection and quality validation process. When required, springs can also be tested on Force Technology’s in-house engine spin test rig. According to Williams, if material is available and in stock, typical manufacturing lead times range from four to eight weeks.

Force Technology is based in Lancashire in the UK. Prof. Miranda Barker OBE, a spokesperson for Lancashire Business Board, said, “Force Technology’s prestigious contract with Cosworth and its other high-value customers in the UK and worldwide reflects the AEM sector’s resilience, innovation and global competitiveness, playing a critical role in driving productivity, exports and sustainable growth.”

Toyota Racing will conduct the first public demonstration drives of its liquid-hydrogen-fueled TR LH2 Racing Prototype at the Circuit de la Sarthe, the venue for the 94th edition of the Le Mans 24 Hours.

The TR LH2 Racing Prototype is based on the same chassis as the TR010 Hybrid Hypercar, which will compete in the Le Mans 24 Hours on June 13 and 14. The prototype is designed to support the development of hydrogen technology in motorsport, contribute to Toyota’s ongoing hydrogen research and infrastructure efforts and help foster partnerships aimed at expanding hydrogen applications through motorsport.

Toyota has taken on the challenge of hydrogen engine development in motorsports, initially through Rookie Racing’s participation in the Japanese Super Taikyu series with the ORC Rookie GR Corolla H2 Concept. From 2021, this vehicle used gaseous hydrogen before the introduction of a liquid hydrogen-powered car in 2023.

The potential of hydrogen engines in rallying was initially showcased in 2022 when the GR Yaris H2 completed demonstration runs at Ypres Rally, a round of the FIA World Rally Championship. Further development was highlighted when the GR Yaris Rally2 H2 Concept conducted demonstrations at the 2025 Rally Finland and this year’s Monte Carlo Rally.

In 2023, the ORC Rookie GR Corolla H2 Concept completed a demonstration lap of the Circuit de la Sarthe, and a hydrogen engine concept car, the GR H2 Racing Concept, was presented to preview a potential future hydrogen category at Le Mans. Since then, development of the technology has intensified, reaching a further milestone with the unveiling of the liquid-hydrogen-powered GR LH2 Racing Concept last year at Le Mans. A year later, the next step in the company’s hydrogen journey is the first public demonstration of the TR LH2 Racing Prototype.

Ferrari has unveiled the all-electric Luce at the Vela di Calatrava – Città dello Sport in Rome in Italy.

Expanding Ferrari’s in-house electric technology expertise has created new opportunities for performance and efficiency across its wider vehicle programs, the auto maker said. This includes technology transfer between Ferrari road cars, the 499P Hypercar that won the most recent World Endurance Championship, and the Ferrari Hypersail project, which serves as a platform for research and innovation. The Ferrari Luce marks the culmination of Maranello’s multi-energy strategy, announced at the 2022 Capital Markets Day.

John Elkann, president of Ferrari, said, “We are not simply unveiling a new car, we are inaugurating a chapter that turns our vision into reality, strengthening Ferrari’s tradition of anticipating and shaping the future.”

In keeping with tradition, Ferrari has chosen to engineer, develop and manufacture the main components in-house. The project includes more than 60 new patents.

The Ferrari Luce was designed in collaboration with LoveFrom, the design collective led by Sir Jony Ive and Marc Newson, bringing an external perspective to Ferrari’s established design approach under Flavio Manzoni.

The electric power source, Ferrari-engineered engines and advanced drivetrain enabled the development of a new architecture that combines Ferrari performance with the luxury of spaciousness. Technologies derived from Ferrari’s unrivalled experience in the world of motor racing made it possible to contain kerb weight at 2,260kg, helping deliver best‑in‑class performance (0–100 km/h in 2.5 seconds, 0–200 km/h in 6.8 seconds, top speed over 310 km/h and maximum total power output of 1,050hp) and a range in excess of 530km.

The car introduces electric all-wheel drive technology, combining torque vectoring, regenerative braking and adjustable power delivery systems. Steering wheel-mounted paddles enable drivers to modify torque output and energy recovery, while Ferrari says the system has been developed to provide a more progressive acceleration response than typical high-torque electric powertrains.

The car is powered by four electric engines, one per wheel, and is equipped with a high‑capacity 122kWh battery, an active suspension system derived from the F80 and an independently steering rear axle. Within this framework of technological innovation, two concepts best encapsulate Ferrari Luce’s ambitious entry into the world of high‑performance electric sports cars: the control of each wheel’s motion in every direction and in any dynamic condition, and the authentic approach to sound.

Each wheel is equipped with one actuator for traction and regeneration, one for the steering angle and one to control vertical movement. The ability to adapt torque distribution in real time to road conditions and desired performance provides exceptional freedom and precision of control. Each of the Ferrari Luce’s wheels is attuned to the driver’s input, enabling the driver to experience a single, fluid movement. Torque vectoring and the elastic balance of the suspension system also assist in changing direction, enhancing the car’s agility and ease of driving.

The Ferrari Luce’s vehicle dynamics have been developed around the characteristics of its electric platform, including a lower center of gravity and revised weight distribution. The vehicle uses an e-Manettino system to adjust power delivery and traction settings, alongside Ferrari’s five-position Manettino drive mode selector, which adapts vehicle responses to different grip conditions.

The model also introduces Ferrari’s new vehicle control unit, which integrates management of the powertrain and vehicle dynamics systems. According to Ferrari, the system processes updates at up to 200 times per second and works in conjunction with the latest version of the company’s Side Slip X control system.

The powertrain comprises four F80-derived permanent magnet synchronous engines with radial flux, delivering a maximum speed of 30,000rpm at the front and 25,500rpm at the rear. The system operates on 800V architecture and combines performance with efficiency, with solutions directly derived from motorsport. The high-voltage battery pack was designed, validated and built in Maranello and comprises 210 cells in series that deliver 122kWh and support fast charging up to 350kW; it has been designed as a structural element of the car. Power electronics feature compact inverters and a DC/DC resonant converter for the active suspension to achieve record-breaking efficiency of more than 98%.

The Ferrari Luce uses an integrated battery, chassis, and body structure designed to improve rigidity, efficiency, and interior packaging. The aluminum-based architecture places the battery beneath the floor and rear seats, removing the need for a central transmission tunnel and increasing cabin space. Ferrari said the structure delivers increased bending and torsional rigidity compared with its previous four-door models.

The vehicle also features double wishbone suspension, rear-wheel steering, carbon ceramic brakes, and a rear subframe mounted to improve ride comfort and handling balance.

The extensive use of recycled secondary-alloy aluminum enables a reduction in CO₂e emissions during production of around 70% of the overall vehicle weight.

Benedetto Vigna, CEO of Ferrari, said, “We are convinced that a company demonstrates its leadership when it has the courage to dare and to take on the challenge of new technologies. Ferrari Luce was born precisely from this challenge, offering our unprecedented vision of electrification.”

To mark its 25 year anniversary, the Ariel Motor Company has launched a 525bhp version of its Atom sports car. The track-oriented but roadgoing Ariel Atom 4RR will feature a bespoke Honda engine and will be “the most powerful and exclusive Atom ever created”, the UK manufacturer said.

The 4RR will feature a hand‑built, motorsport‑spec engine producing 525bhp and revving to 8,200rpm and will be the fastest Atom yet, capable of 0-62mph in 2.4 seconds and hitting 100mph in just 5.1 seconds.

The most powerful Atom

Despite its focus on ultimate circuit performance, the 4RR remains a road‑legal vehicle. Each 4RR will be uniquely specified and built to order with buyers invited to Ariel’s factory in Crewkerne in the southwest of the UK to specify and discuss their vehicle with the engineers and technicians responsible for constructing their car.

Simon Saunders, founder of Ariel Motor Company, said, “The Atom 4RR is the most focused vehicle we’ve ever built – a car that captures everything we’ve learned over 25 years of pure driver‑focused engineering. It is the fastest and most powerful Atom to date, yet it stays true to our founding principles of lightweight, minimalism and delivering very serious fun. It is the most direct connection between car, driver, and track or road, that we have ever made.”

Bespoke motorsport‑spec engine

At the heart of the Atom 4RR sits a bespoke 2.0L four-cylinder Honda K20C Type R that is hand-built in 100 hours. However, almost every significant internal and external component has been replaced, upgraded or re‑engineered to motorsport specification.

Henry Siebert-Saunders, managing director at Ariel Motor Company, said, “The 4RR’s engine is built by hand taking more than 100 hours with the objective of delivering intense performance right at the pinnacle of track driving while remaining controlled and confidence-inspiring on road.”

Internally, the engine is comprehensively uprated with closed deck sleeves, bespoke forged pistons and connecting rods, revised cylinder head and port geometry, bespoke camshafts and alloy valve set with uprated springs and guides. All rotating components are measured, fully weight‑matched and dynamically balanced.

With circuit running a primary focus, the 4RR engine features a race‑spec gated oiling system and a high‑flow oil pump, ensuring consistent lubrication under prolonged high engine loads and cornering. Performance and durability are further enhanced by a competition‑grade head gasket with reinforced fire‑ring sealing and a race-spec cylinder‑head stud kit designed to withstand extreme cylinder pressures.

A larger turbocharger peaks at 1.7 bar boost, while a high-pressure fuel system and 1,400cc fuel injectors deliver immense mid‑range torque and a ferocious top‑end – maintaining the consistency and resilience required for circuit use. The 4RR features three cockpit-adjustable engine maps with different boost levels: Map 1 – 400bhp/380Nm; Map 2 – 500bhp/450Nm;  Map 3 – 525bhp/550Nm. Each hand-built engine is run-in and tested on a dyno before final calibration and power tests. An individual dyno graph will accompany each bespoke Atom 4RR engine.

A new carbon air inlet system, with remote air filter assembly, and a new full titanium exhaust and silencer system will be fitted to the Atom 4RR, with power delivered through a Quaife six-speed sequential gearbox with lightweight drive discs, motorsport differential and pneumatic paddle shift, ensuring traction and consistency at all times. Clutchless up and down shifts can be made with auto-blip on downshifts and the lightweight clutch only used for initial start.

Motorsport‑optimized and aero‑led performance 

The 4RR features a fully bronze-welded motorsport chassis with adjustable Öhlins dampers, aluminum uprights and chromoly wishbones for precise handling. Braking comes from 310mm AP Racing discs with four-piston calipers and race-spec pads, paired with in-cockpit adjustable ABS for consistent, high-performance stopping under all conditions.

Ariel has designed the 4RR’s aerodynamic package to maximize downforce while minimizing drag, delivering exceptional cornering speed and high-speed stability. Redesigned carbon-fiber side pods improve cooling for the engine and gearbox, supporting higher power and extended track sessions. Lightweight carbon-fiber bodywork, mudguards and aerofoils further reduce overall weight.

The Atom 4RR rides on forged wheels – 7Jx16 at the front and 9Jx17 at the rear – fitted with road-legal Yokohama A052 tires in 195/50R16 and 255/40R17 sizes.

Siebert‑Saunders said, “The Atom 4RR is the most uncompromising car we’ve ever created. Every component, every weld, and every element of its engineering is focused on delivering ultimate track performance at the highest level. Its performance capability demands respect while rewarding drivers with an intensity and precision that few other cars can match.”
