You knew this was coming. Introducing the McLaren 600LT, the long-tail, more-horsepower top-dog cousin of the McLaren 570S. And while McLaren will continue to keep certain details away from us until the 600LT’s dynamic debut at the Goodwood Festival of Speed next month, here’s everything we can tell you now about Woking’s latest Long Tail.

By the numbers, 23 percent of this “strictly limited volume” car is new, not shared with the 570S. There’s a lot more carbon fiber, as well as forged aluminum double-wishbone suspension and lightweight braking system inherited from the 720S. All those upgraded components save 211.6 lbs. in total, bringing the 600LT’s dry weight (with all the required options ticked) to 2749.2lbs. Yeah, there’s a 0.2 there, because it’s McLaren.

Thanks to the uprated cooling and the reduced backpressure provided by the shorter, top-exit exhaust system, the 3.8 twin-turbo V8 now produces 592 horsepower and 457 lb.-ft. of torque. With that extra power comes quicker steering, sharper throttle and brake pedal responses, significantly firmer engine mounts, and a set of bespoke, track-focused Pirelli Trofeo R tires on forged wheels.

To justify the Long Tail badge, the 600LT is 2.9 inches longer than a regular Sport Series, thanks to having an extended front splitter, a massive rear diffuser and a fixed rear wing. This package produces a considerable amount of downforce.

Inside, everything is wrapped in Alcantara, and while the standard seats are the carbon buckets first seen inside the McLaren P1, customers can also opt for the McLaren Senna’s even lighter carbon units. Add MSO’s carbon roof, cantrails and the vented carbon front fenders, and the 600LT’s dry weight suddenly drops to the lowest claimed figure, 2749.2 lbs.

Limited production of the 600LT Coupé will begin in October, and will last for no more than 12 month. But just how limited are we talking here? The predecessor 675LT’s figures should give you an idea—a mere 500 examples of that car were produced. Pricing will also have to stay under wraps for now, but I can tell you that McLaren will throw in a Pure McLaren Road Owner Track Day at a race circuit, just to make sure you can handle the 600LT’s amplified fury.
