The Lotus Evora 400, the fastest road-going Lotus, was officially unveiled in Geneva by Lotus chairman Tun Dr Mahathir Mohamad, Proton CEO Datuk Abdul Harith Abdullah and Lotus CEO Jean-Marc Gales.

Details of the car were revealed last month – the 3.5 litre V6 engine gets a new supercharger, a water-to-air charge-cooler and a revamped engine management system, which bumps up output to 400 hp – up by 55 hp from the Evora S – and 410 Nm.

The car also gets reworked muffler internals and new engine mounts, and the six-speed manual transmission now has a new low inertia flywheel and a reworked clutch disc for better shift quality, and Torsen-type limited slip differential has been plonked on as well. Rated top speed is 300 km/h, and the century sprint is accomplished in 4.2 seconds.

Production of the Evora 400 begins in the summer, with first deliveries set to start in August. The company also announced in Geneva that combined production of Lotus models is set to increase to 70 cars per week from September this year, and that it will be adding 150 new personnel to its production taskforce.
