So as we get closer to the 2015 Geneva Motor Show where the new McLaren 675LT will make its official debut, the British super car maker releases new details on the modern-day ‘Long Tail’. It is going to be substantially different from the 650S on which it is based.

The McLaren 675LT was first thought to be a mildly face-lifted version of the existing 650S. But based on the details, pictures and videos released so far, the LT is heavily revised in almost all areas. Visually, the use of active aerodynamics and new exhaust system has given the 675 a meaner, more aggressive look, while under the engine lid the 3.8 liter V8 is more powerful than ever.

That brilliant twin-turbo unit started out with around 590 horsepower in the first 12Cs and gradually grew up to now make 675 PS (666bhp) in the McLaren 675LT, along with 700 Nm (516 lb ft) of torque. What’s more, it now sounds better than ever thanks to a new crossover exhaust system made from lightweight titanium. The system’s two huge tailpipes just below the rear ‘Longtail’ Airbrake are the biggest distinguishing feature of the car.

McLaren 675LT will launch later this year as a coupe only, and it’s meant to be a track-focused alternative to the softer and cuddlier 650S. Performance figures and pricing will be announced at the Geneva Motor Show.
