McLaren isn’t ready to take the wraps off its 675LT just yet, but it just let slip a few more technical details ahead of the new supercar’s debut at the 2015 Geneva Motor Show.
The 675LT is inspired by the McLaren F1 GTR “Longtail” of the 1990s, and like that race-winning car, it features modified bodywork for better aerodynamic performance.
That includes a new air brake with twin exhaust tips exiting the bodywork just below it. Combined with other styling changes, McLaren says this will yield 40 percent more downforce than the 650S the new car is based on.
The 675LT will use a version of McLaren’s ubiquitous twin-turbocharged 3.8-liter V8, tuned to 666 horsepower and 516 pound-feet of torque.

McLaren installed new turbochargers and a lightweight titanium exhaust system. Torque delivery is also stepped to prevent overwhelming the tires when the driver accelerates from a standing start.
Along with the 650S and the Asian-market 625C, the 675LT will be part of the newly-christened “Super Series,” differentiating the three related models from McLaren’s upcoming Sports Series.
Expected to debut at the 2015 New York Auto Show about a month after the 675LT’s unveiling, the Sports Series will be an “entry-level” model that’s smaller and less powerful than the Super Series, but also less expensive.
We’ll have full details on the McLaren 675LT when the 2015 Geneva Motor Show opens next month.
