As with Lamborghini, the figures that McLaren uses for the names of its cars correspond to the power of the engine. Here, a 3.8-litre twinturbo V8 delivering 675 hp. Launched in early 2015, the 675 LT is distinguished from the 650 S, which was launched a year earlier, by its power, its reduced weight but also its redesigned rear part, LT meaning “long tail”.
