Want a lighter and more powerful 720S? McLaren has just the ticket and you’ll be getting quite a few tickets if you’re not careful with the new 765LT.

For improved handling, the new supercar gets a redesigned front splitter, front bumper, side skirts, rear bumper, and rear diffuser but its biggest party trick is its hydraulically-operated rear wing. Not only is it bigger than that on the 720S but it is positioned higher even while it's resting and it fully deploys when you smash the brake pedal and improves downforce by 25 per cent.

It weighs 80kg less than the 720S (1,229kg) and McLaren cut the fat by using lighter body panels made of carbon fibre, thinner glass, and took away the AC and even the radio.

Power comes from a twin-turbocharged, 4.0-litre V8 which produces 755 horses at 7,500 rpm and 800Nm of torque at 5,500 rpm. Mated to a seven-speed automatic (with comfort, sport, and track modes) it shifts 15-per cent faster than a 720S and allows the newbie to do 0-100kph in just 2.7 seconds.

It also gets updated springs with updated algorithms for the Proactive Chassis Control II suspension control system and a quicker steering ratio.

The cabin is swathed in carbon fibre (its on the seats, centre tunnel, and even exposed parts of the floor).

Just 765 examples will be built with deliveries beginning in September of 2020.
