The historic Honda F1 RA1082-001 chassis has been brought back to life! Read how the dedicated craftsmanship of Lee at Formula Car Hire combined an iconic KERS prototype tub with a screaming AER P57 V6, fully mapped for absolute on-demand reliability by the engineering team at Bourne HPP.
At Bourne HPP, our high-tech rolling road dyno cell is trusted implicitly by the motorsport industry to calibrate, map, and test some of the world's most exclusive and technologically significant racing machinery. Last week, it was an absolute privilege to support Lee's meticulous build and welcome this true unicorn of Grand Prix history to our facilities.
To the casual observer, this looks like a standard mid-2000s Formula 1 car. But under the skin, this exact Honda F1 chassis represents the definitive physical link to the modern hybrid racing era. Bearing the original, factory-stamped RA1082-001 chassis mark, this very tub was the foundational platform used by Honda to pioneer high-voltage energy recovery.
The Birth of the F1 Hybrid (2008)
To understand why this specific tub is so special, you have to go back to the summer of 2007, when the FIA announced that the 2009 season would permit Kinetic Energy Recovery Systems (KERS). The rules allowed teams to harvest braking energy and deploy up to 60 kW (around 80 bhp) of rear-wheel drive assist per lap, with a maximum energy use limit of 400 kJ per lap.
While most teams were still analysing the regulations on paper, Honda's engineers fast-tracked development. To package the system on an actual vehicle without altering their active racing fleet, they built a one-off special test mule. The Honda R&D engineers took an older RA106 chassis (originally raced in 2006, and later utilised by Super Aguri) and extensively modified the structural area around the fuel cell to accept the new high-voltage battery pack. This custom architecture ensured that the test car retained its original center of gravity as much as possible, giving birth to the Honda RA1082.
In April 2008, the build was completed, and Alex Wurz completed a brief 2.4 km shakedown run at the Santa Pod drag strip. However, because the build schedule had overrun, the hybrid electronics could not be fully operated during that initial outing. A week later, after resolving initial integration issues at the factory, the team hit the track for realistic testing.
In May 2008 at the Silverstone National Circuit with James Rossiter at the wheel, Honda became the first team in the F1 modern era to test a hybrid system on a full circuit, running the KERS at a 25 kW assist and 35 kW recharge profile.
The Original High-Voltage Specs:
To bypass the strict F1 engine development freeze (engine homologation) in effect since 2006, Honda could not make changes directly to the engine crankshaft or block. They had to get radically creative with packaging:
-
The Transmission Motor: The Motor Generator Unit (MGU) was neatly integrated inside the transmission casing, connected to the lay shaft gears. To minimise case bulges and avoid interfering with rear aerodynamics, the MGU's diameter was tightly constrained to just 100 mm. It was a brushless DC motor designed to spin at an incredible 21,000 rpm, using direct cooling oil from the gearbox.
-
The Monocoque Core: The water-cooled Power Control Unit (PCU) and a custom 114-cell lithium-ion battery pack were tucked neatly inside the altered monocoque cavity.
-
The Fuel Sacrifice: Placing this heavy hardware inside the tub drastically penalised fuel cell capacity. The original RA106 fuel tank could hold 140 litres, but on the modified RA1082, it was slashed by roughly 40% dropping to just 83 litres.
Ultimately, the engineering paid off. Following testing upgrades by Mike Conway up to the full 60 kW limit at Silverstone Stowe, the RA1082 was shipped to Jerez for official F1 group testing. Telemetry confirmed that deploying the full 400 kJ of harvested energy gave the car a 7.1 km/h top-speed advantage down the straightaway and slashed total lap times by 0.4 seconds.

The Next Stage of Life: The Resurrection
When manufacturer teams leave Formula 1, they don't typically sell their running power units. To protect proprietary secrets, Honda completely destroyed and melted down their factory F1 engines from this era. That left this historic milestone as a silent, engineless rolling shell.
That is where Lee from Formula Car Hire stepped in. Having acquired the genuine, stamped RA1082-001 chassis, Lee set out on a dedicated mission of craftsmanship to return this legend to live operational status for exhibitions, displays, and corporate events.
Lee executed a brilliant piece of motorsport matchmaking. He sourced a naturally aspirated Advanced Engine Research (AER) P57 3.5-litre V6 and mated it to a lightning-fast Hewland 6-speed sequential gearbox. To govern this bespoke powertrain configuration, the car is now running on a top-tier Life Racing F88RS ECU, the perfect electronic brain for managing a high-revving formula engine package.
The car that birthed the modern hybrid era had effectively been reborn as a pure, screaming, naturally aspirated V6 display car.
Fine-Tuning a Legend at Bourne HPP
Bringing a highly specialised, bespoke build like this to life requires a unique calibre of engineering. You cannot just plug a laptop into an F1 monocoque and hope for the best; the electronics, shift cuts, and operational parameters all have to be perfectly synchronised.
For this specific project, the calibration remit on our rolling road was highly focused. The primary requirement for the mapping was absolute reliability: the car needed to start strictly on demand and deliver smooth, predictable drivability for repeated public displays and live events. Peak horsepower figures took a back seat to seamless transient throttle response and operational repeatability.
This is where Bourne HPP was proud to assist Lee’s meticulous craftsmanship. Our Managing Director, Terry Radbourne, was perfectly suited for the task. Earlier in his career, Terry spent a significant period working trackside and in development for AER, dealing directly with the P57 V6 engine platform. He followed that with a tenure as an F1 engine engineer at Mercedes AMG High Performance Powertrains. Terry specialises heavily in mapping and optimising Life Racing control units.
Starting completely from scratch, Terry built a bespoke baseline engine map to establish optimal starting and idling parameters. From there, he systematically tuned the engine across the entire rev range on the rollers. By focusing intensely on fuel delivery, transient load transitions, and ignition timing, Terry optimised the pneumatic gear shift strategies for the Hewland transaxle. This custom-tailored approach created a beautifully linear, progressive power delivery, leaving an incredibly stable starting and running cycle that ensures the classic carbon tub performs flawlessly on demand.
Keeping History Loud
The Honda F1 RA1082-001 may have never officially lined up on a Sunday Grand Prix grid due to Honda’s sudden exit from the sport at the end of 2008, but thanks to Lee's vision and dedication at Formula Car Hire, this incredible piece of history isn't locked away in a silent museum. It is alive, it is operational, and it runs beautifully on demand. We are incredibly proud to have played a part in writing its next chapter.
