The monocoque, or ‘tub’ as
it is known, is made from carbon fibre with an aluminium honeycomb core. From 2005 it was manufactured
to incorporate the HANS device and an extractable seat for added driver safety.
There is a variety of choice when it comes to which power unit to install. Mugen-Honda,
Mercedes-Benz and VW are the engines of choice when competing in British F3.
6-speed sequential gearbox.
Double wishbone, push-rod system. The Litespeed R1 is unique in that it has a choice of
configurations: single (mono-shock) conventional, twin or triple layout. Each system is particularly
useful in the British F3 International series due to the wide variety of circuits visited.
Bodywork / aerodynamics:
Aerodynamics are a vital part of the overall design
of an F3 car. With similar flow structures to that of an F1 Grand Prix car and with a stepped floor,
the F3 racer is in essence a mini-F1 car. There are strictly regulated FIA-homologated parts of the car
such as the engine, gearbox and chassis as well as mandatory ‘spec’ rear
wing elements. However, creativity is given a free rein when it comes to designing the side-pods, undertray
and diffuser. To confer a competitive advantage, the team at Litespeed F3 can optimize the R1’s
aerodynamics by using a scaled-down (45%) wind tunnel model for minimum drag and maximum downforce and
Top speeds in excess of 160 mph depending on the circuit
and gearing; 0–60 mph
in 3.0 seconds and 130 to 50 mph deceleration in 2.8 seconds.
