Changes on the exterior include a newly designed front bumper with a large carbon fibre front splitter at the base, an extra cooling intake nested in
a larger door blade and end plates ahead of the front wheels.
In addition to lightweight engine and chassis components, the McLaren 675LT uses carbon fiber for its extended front splitter,
door blades, side sills, rear bumper, rear diffuser, and 50 - percent
larger (but lighter) Longtail active airbrake.
