It’s tough not to fall in love with a vehicle that was built with the track in mind, yet is fully street-legal. That’s part of the allure with the McLaren 675LT, which is set to be unveiled at the Geneva Motor Show next week. The most powerful and lightest model yet in McLaren’s Super Series makes the most of the twin turbo 3.8-liter V-8 engine, with a zero to 60 mph time in less than 3 seconds thanks to 666 horsepower and 516 pound-feet of torque. And as you’d expect, carbon fiber is a big reason it’s so light, used everywhere from the front splitter to the seat shells and rear bumper. A sportscar as comfortable on the track as it is around town.
