A new generation transmission, the F3B uses advanced, modern technology to bring maximum performance to your vehicle. Designed for use with Dallara’s latest Formula 3 cars, the F3B transmission provides high performance while meeting the latest and most stringent F3 regulations.


The design incorporates a dedicated engine oil tank, giving an overall vehicle weight saving and allowing for maximum engineering freedom elsewhere on the vehicle.

Further reliability and enhanced performance can be achieved using Hewland’s fully integrated Semi-Auto ‘Paddle Shift’ system. Proven in series’ across the world, this option allows for significant weight and space saving on the vehicle, whilst improving performance and component life.

With internals taken from the prolific FTR family, Hewland reliability is guaranteed. Combined with various differential options, including the advanced Powerflow™ unit, the F3B has the performance to provide our clients with a winning advantage over the competition.
