JCB aims to crush the world land speed record with its new 350 mph hydrogen racer
Keypoints
- JCB revealed the Hydromax, a hydrogen-powered vehicle aiming to exceed 350 miles per hour at Bonneville.
- The streamliner features two modified hydrogen engines producing 1,600 horsepower to power all four wheels.
- Legendary pilot Andy Green will drive the vehicle to break existing hydrogen and diesel speed records.
British manufacturing giant JCB has officially revealed its latest engineering marvel designed to shatter existing zero-emission speed records on land. The company is heading back to the famous Bonneville Salt Flats in Utah with a hydrogen-powered vehicle named the Hydromax.
Measuring nearly ten meters in length, this streamliner targets a maximum speed exceeding 350 miles per hour. If successful, the ambitious run will comfortably break multiple records for hydrogen vehicles in a single attempt.
JCB HYDROMAX TARGETS A HISTORIC REWRITING OF LAND SPEED RECORDS
The current speed record for a hydrogen internal combustion vehicle stands at a modest 187.62 miles per hour, which was established by BMW’s H2R prototype. JCB intends to nearly double this figure during its official testing window scheduled for this coming August.
Additionally, the team wants to surpass the absolute record for any hydrogen powertrain, currently held by Ohio State University’s fuel-cell Buckeye Bullet 2 at 303 miles per hour. The engineering team believes the advanced streamliner can comfortably outperform both legacy benchmarks.

MASSIVE POWER ENGINES AND ADVANCED AERODYNAMIC SIMULATIONS
The mechanical core of the Hydromax consists of two proprietary hydrogen internal combustion engines producing a combined output of 1,600 horsepower. These power units are highly modified versions of the exact same engines currently deployed in JCB’s commercial production excavators.
Each engine delivers 800 horsepower directly to an advanced twin-clutch dual-transmission system that effectively powers all four wheels. Every mechanical aspect, including suspension geometry and traction control, underwent extensive virtual simulations before the physical vehicle was built.
Engineers completely redesigned the sleek bodywork from the ground up to achieve maximum aerodynamic efficiency on the salt flats. The vehicle represents a massive technological evolutionary leap compared to the older diesel-powered JCB Dieselmax model.
LEGENDARY FIGHTER PILOT RETURNS TO THE BONNEVILLE SALT FLATS
Royal Air Force Wing Commander and experienced fighter pilot Andy Green will take the wheel for this historic speed run. Green is deeply familiar with extreme speed challenges and previously drove the original Dieselmax vehicle to a record-breaking performance.
In 2006, he set a diesel land speed record of 350.092 miles per hour that remains completely unbeaten to this day. Furthermore, he remains the only human being in history to have successfully broken the sound barrier on land.
Green expressed immense confidence in the new zero-emission machine, noting it is significantly lighter and faster than its twenty-year-old predecessor. He stated that the project will demonstrate the sheer capabilities of British engineering to a global audience.

STRATEGICΒ INDUSTRIAL INVESTMENTS PATHWAY FOR HEAVY MACHINERY
Behind the record-breaking public spectacle lies a major financial and industrial strategy for the commercial equipment manufacturer. JCB has invested 100 million pounds over a five-year period to develop this clean hydrogen combustion technology.
This strategic development window comes just before the company inaugurates a new 500 million dollar manufacturing megafactory located in San Antonio, Texas. The company views the project as the perfect proof-of-concept for zero-emission technology on a global stage.
While battery-electric setups and fuel cells dominate the passenger car industry, JCB firmly advocates for hydrogen combustion in heavy equipment. The company highlights that heavy industrial sectors require superior energy density and incredibly fast refueling times to remain productive.
Company chairman Anthony Bamford explained that putting an advanced engine into a land-speed car proves capabilities in ways a standard digger never could. He emphasized that any serious discussion regarding zero emissions must include hydrogen technology as a core pillar.
