CASE STUDY

Subaru GT300 – BRZ
The new 2017 Subaru Tokyo R&D BRZ entry to the popular Super GT300 series is the ultimate show case of Subaru’s boxer engine technology combined with Hewland’s GT Racing competition transmission.

Super GT is a racing series that began in 1993 and it is the top level of sports car racing in Japan sanctioned by the Japan Automobile Federation (JAF). GT300 cars closely resemble their road-going versions. GT300 engine horsepower range varies from around 400 to just over 500 horsepower.

Hewland wanted to bridge the gap between their successful Le Mans competition transmissions and the needs of GT Racing Series. The Hewland GTT-200 transmission is optimised for front engine rear wheel drive GT cars and utilises the latest in Hewland’s performance gear design and optimised magnesium packaging. At just 65Kg, the GTT-200 800Nm-rated package takes the proven LMP2 gear cluster and integrates it into a compact package for the highest performance GT cars. Hewland took the GTT-200 from a blank sheet of paper to integrating the transmission into the first BRZ in just 20 weeks.

Subaru selected the transmission to combine with their impressive boxer engine to reduce overall vehicle weight by as much as 20kgs, this is achieved by integrating the differential and gearbox in a single package as well as advances in thin walled magnesium casings allow for this significant weight reduction.

The new car’s first season (2017) has seen it prove to be very competitive with a 2nd place podium finish at Autopolis speedway and several other strong placings.

The GTT-200 is available now for all front-engine, rear-drive GT cars.
