After announcing the 2015 McLaren Sports Series, the company recently released a camouflaged image of the car on their official Facebook page.
We really can't see much, but it is clear that the Sports Series takes many of its design cues from other McLaren models such as the P1.
McLaren has not yet stated any official specs but they did announce that the 2015 Sports Series will utilize a carbon fiber chassis along with a mid-mounted V8 engine.
The car will debut at the second quarter of 2015 and will slot below the 650S. It will make use of technologies from both the McLaren P1 and Formula 1 cars.
