The 2015 McLaren 540C was officially revealed at the 2015 Shanghai Auto Show. This is the second member of the Sports Series lineup and comes with a design that is hard to distinguish when placed to a 570S. 

There are a couple of subtly revised aerodynamic accessories and new wheels, but in the end, the car is the same. Inside the cabin, the McLaren 540C has premium leather upholstery, and a seven inch infotainment system with Bluetooth connectivity and GPS navy. 

Under the hood of the McLaren 540C is a V8 3.8 liter twin-turbo engine rated at 540 horsepower and 540 Nm peak of torque. The engine is matted to a seven speed SSG transmission that enables the car to run from stand still to 100 km/h in 3.5 seconds. The run from 0 to 200 km/h is done in 10.5 seconds, while the top speed is clocked at 320 km/h. 

Thanks to a start stop system, the McLaren 540C can return 9.2 liters per 100 kilometers with CO2 emissions of 258 grams per kilometer.
