Adhering to McLaren's current naming convention, the new 675LT will feature a 496kW (675PS) version of the company's 3.8-litre twin-turbocharged V8 engine.

The modifications to the engine make it 18kW more powerful than the one fitted to the 650S, but still a long way short of the 673kW drivetrain available in the hybrid P1. In addition to the extra mumbo, the 675LT is said to be lighter than the 650S.

According to McLaren, the 675LT is named after the F1 GTR Longtail, and as such will feature aerodynamics and downforce that's been tuned for increased performance.

Along with the Asia-only 625C and the 650S (above) that's sold in the rest of the world, the 675LT will be part of McLaren's Super Series of vehicles. The Super Series will sit above the entry-level Sports Series, which will be unveiled in the second quarter of 2015.

Alongside the 675LT on the McLaren's Geneva motor show stand will be the production-ready version of the hyper-exclusive and track-only P1 GTR. The 675LT will only be sold as a coupe and will head into showrooms later this year.
