McLaren has confirmed that it is to unveil its new 675LT model at the Geneva Motor Show in March.
Sharing a show-stand next to the track-only P1 GTR, the new model joins the newly named McLaren Super Series, which already consists of the 650S (formerly the 12C) and the Asian-market only 625C.
McLaren is describing the 675LT as the "lightest, quickest and purest" model in the range. Its LT nomenclature pays homage to the 'Long Tail' McLaren F1 GTR race car that took second place at the 24 Hours of Le Mans in 1997.
As a performance range-topper for the Super Series of cars, the 675LT uses an uprated version of McLaren's 3.8-litre twin-turbo V8 engine. Power is up to 666bhp (or 675PS – hence the name) from 641bhp.
McLaren has yet to publish performance figures for the new model, though expect slight improvements on the 650S's 3.0-second 0-62mph sprint time and 207mph top speed.
Spy pictures of development prototypes, as above, show that the 675LT will share its basic design with the rest of the Super Series, though has tweaked bodywork to maximise aerodynamic efficiency and available downforce. McLaren also claims the new car will weigh 100kg less than the 650S.
