675LT coupe, the limited-edition, track-focused model in the Super Series line-up. It establishes a psychic connection with the McLaren F1 GTR Long Tail developed in 1996 to battle the Mercedes-Benz CLK GTR and Porsche 911 GT1. This is what you should know about the 675LT: it's really, really comfortable. Almost excessively so.

At heart is the twin-turbo 3.8-liter V8 found in all McLaren models, but more than half of its components are new for this application. The camshaft is new, the block gets lightweight connecting rods, the fuel pump is upgraded, the twin turbos are the same size as those on the 650S' engine yet more efficient. Final output is 666 horsepower and 516 pound-feet of torque, an increase of 25 hp and 16 lb-ft over the 650S.

For all that precision, the 0-60 mile-per-hour time of 2.8 seconds is only one tenth under that of the 650S, and its top speed is 205 mph, compared to the 207-mph terminal velocity of the 650S.
