Revolution Race Cars reveals details of HyperSport powertrain

Following the unveiling of the Revolution HyperSport in April, Revolution Race Cars has released further technical information on the car’s powertrain package, underlining a clear focus on durability, responsiveness and drivability for track-day and racing use.

At the heart of the HyperSport sits a mid-mounted 2.0-litre turbocharged inline four-cylinder engine. Based on the proven Mazda MZR architecture, the unit has been extensively re-engineered to motorsport specifications, with bespoke internal components designed to withstand sustained high-load circuit use and align with the company’s mantra for the HyperSport: ‘Designed to exhilarate, not intimidate’.

The 300+ bhp engine enables the HyperSport to achieve its target of delivering more than 430 bhp/tonne. This positions the car as an attractive option for race teams and driving experience companies requiring minimal downtime and maximum track time.

The engine programme has been developed in partnership with Revolution’s long-standing technical partner, RLM Racing. The Rutland, UK-based company previously worked with Revolution on the 500 bhp supercharged V6 engine for its flagship 500 EVO model and has now brought that expertise to the HyperSport programme.

Key to the build is a fully forged rotating assembly, incorporating competition-grade pistons and H-beam connecting rods, combined with RLM’s precision balancing. This approach is aimed not only at maximising outright performance, but also ensuring long-term reliability under sustained high-rev operation.

The cylinder head specification reflects a similarly focused brief. Race-derived cam profiles are combined with an uprated valvetrain package engineered for high engine speeds, allowing the powerplant to operate at high performance levels without compromising mechanical integrity.

The motorsport-proven turbocharger is matched to the engine’s characteristics by RLM to prioritise throttle response and linear power delivery. Boost control is managed through a Tial external wastegate system, providing accurate and repeatable regulation under varying load conditions.

RLM’s development philosophy centres on producing a power unit that complements the HyperSport’s lightweight composite chassis and low-drag aerodynamic concept. The emphasis is not solely on peak output, but on delivering a broad, usable torque curve and predictable behaviour. These are key attributes for a car intended to be both confidence-inspiring and highly capable on track.

The rear wheels are driven via a six-speed sequential gearbox by FIA Formula 3 supplier 3MO. The engine and transmission are stressed members of the chassis, with the rear suspension mounted to the gearbox’s bespoke casing. The gearbox is to the same specification as the one proven on the more powerful 500SC, underlining Revolution’s commitment to specifying the car for durability as well as lightness.

Every element of the package reflects a deliberate effort to balance performance with serviceability and longevity, reinforcing Revolution’s wider objective of reducing the operational barriers typically associated with machinery at this performance level.
