The Tatuus-Cosworth BRDC British F3 Car



The Tatuus-Cosworth car is a powerful car with a more sophisticated aerodynamic package and increased downforce which elevates its pace to close to European Formula 3.

The car utilises a carbon-fibre Tatuus chassis and is powered by a 2-litre 230bhp spec Cosworth engine. The F4-016 meets all the latest FIA Formula 3 safety regulations including side impact panels, front and rear carbon impact structures, wheel tethers and extractable seat.

An improved aerodynamic set-up includes a highly adjustable front-wing and two piece rear-wing, and an F1-style front splitter and rear diffuser, which provides the most downforce in class.

It features a six-speed sequential gearbox with paddle shift provided by Sadev and fitted with a limited-slip differential, unique to BRDC British Formula 3.

Pirelli will continue to provide both dry and wet tyres to British Formula 3 Championship.

The braking system is supplied by AP Racing and features 4-piston front calipers and floating, grooved and ventilated discs with 2-piston rear caliper and fixed vented rear disc.

Twin wishbone suspension with two-way adjustable dampers and adjustable front and rear anti-roll bars will provide drivers with plenty of scope for set-up changes.
