BRITISH sports car maker McLaren has a new longtail model in the shape of the 600LT and it's the fastest, most powerful and track-focused road car the company has created.
With 600ps on tap from a twin-turbo 3.8-litre V8 engine the 600LT has a power-to-weight ratio of 481ps per tonne.
It will be built in limited numbers and priced from £185,000 which includes a track driving training session.
The 600LT has a 74mm longer body than other models in the McLaren Sports series line up and comes with a new front splitter, side sills, and extended diffuser and a fixed rear wing.
Following on from the legendary McLaren F1 GTR Longtail race car and the 675LT Coupe and Spider, it is only the fourth longtail model to be produced by the brand.
Compared to a 570S Coupe on which the new longtail is based more than 23 per cent of the parts are different and lightweight construction has seen a weight reduction of 96kg taking the 600LT's dry weight down to 1.274 tonnes.
The car comes with a special exhaust system including top-exit pipes and the cockpit has carbon fibre racing seats first seen on the McLaren P1.
It sits on Pirelli P Zero Trofeo R tyres designed for track and road use and comes with uprated suspension to handle the added power.
Exact performance data is still to be released and production of the 600LT is slated to start in October and will last for around 12 months, with build slots scheduled around existing Sports and Super Series models, as well as the sell-out Senna, Senna GTR and BP23.
