McLaren has officially pulled the wraps from the 675LT (Longtail), the latest addition to its Super Series range.

The new car is more track-focused than its stablemate the 650S and according to global marketing director, Jamie Corstophine, is something customers have asked for, rather than a point-scoring exercise in bettering competitors’ performance figures.

The new car goes on sale in July at a price of £259,500 and will be limited to 500 units. The 675LT is 100kg lighter and at 666bhp, 25bhp more powerful than the 650S, and that much was revealed before the show. However, further details revealed by McLaren suggest technical changes should add up to an enhanced driving experience that goes beyond mere brute power.

First, there’s the weight: 100kg is a lot. It’s the equivalent of an average male person plus an airline baggage allowance. “The reduction in mass makes the biggest difference to the way the car feels,” says Mark Vinnels, McLaren’s programme development chief.
