At the heart of the McLaren 600LT lies a mid-mounted 3.8L V8 engine fed by two turbochargers. It's the same engine that powers most of McLaren's other cars; in the 600LT it makes 592 horsepower. That power is sent to the rear-wheels via a 7-speed dual-clutch automatic. That's 30 more horsepower than is produced by McLaren 570S and 570GT, two cars that share their chassis with the 600LT. In addition to that extra horsepower, the 600LT also gets a fair number of styling and chassis tweaks, including a bunch of extra carbon fiber bodywork. This means that the 600LT also weighs less than the cars it's based on, with McLaren claiming 220 lbs of weight savings over the 570S. Additional exterior tweaks include a bigger, fixed spoiler and top mounted exhaust pipes which not only look and sound cool, but also blow additional air over that larger spoiler. Underneath, the 600LT gets forged aluminum suspension components based on those used in the more expensive 675LT. The brakes are also from McLaren's Super Series, with carbon ceramic rotors all around vs the steel units typically seen on the 570S and 570GT. McLaren street cars have always been incredibly fast. However, McLaren also likes to emphasize that they design their cars to be very drivable every day on the street. This starts with suspension tuning that offers a better than expected ride and continues with a cockpit that's full of soft touch materials and the latest electronic goodies. Interiors can be covered in either lightweight Alcantara or luxurious Nappa Leather, though plenty of exposed carbon fiber tastefully makes its way into the interior as well, while a 12-speaker Bowers and Wilkins stereo is also available as an option. Satellite-based navigation and air-conditioning can be deleted at no cost by the customer if they want to save weight, and the whole cockpit has a simple, yet comfortable feel to it, with many of the controls relegated to a 7.0-inch touchscreen in the center console.
