It was originally announced in February 2014 and was first shown at the 2014 Geneva Motor Show in March 2014.
The 650S was planned as a model to fill the gap between the McLaren MP4-12C and the McLaren P1. However, McLaren ended the production of the MP4-12C shortly afterwards, and plans to place the 650S as a mid-range model between the forth coming 625C and 675LT.
The 650S shares many features with the MP4-12C. It is fitted with an upgraded version of the M838T V8 engine, shares the same carbon fibre tub, and is fitted with the MP4-12C's seven-speed dual-clutch gearbox which has been tweaked for quicker gear changes.
Need for Speed: No Limits
