Dutch media is reporting McLaren will unveil a "GTR" version of the 650S bringing more power in a lighter package.

The "GTR" designation is not confirmed but whatever the car's name will be, it will not include the "650S" moniker. More importantly, this will be a higher specification version packing a more powerful 3.8-liter twin-turbo V8 engine which in the 650S delivers 650 HP (478 kW) and 678 Nm (500 lb-ft). The same report mentions a 100 kg (220 lbs) diet is being planned which means the hotter version will have a dry weight of around 1,230 kg (2,712 lbs).

The added power combined with a lower weight will enable the model to be faster than the 650S Coupe which needs three seconds to get from 0 to 62 mph (100 km/h) and 8.4 seconds from a standstill to 124 mph (200 km/h). The 0-186 mph (0-300 km/h) sprint takes 25.4 seconds in the 650S which tops out at 207 mph (333 km/h).

The enhanced version will also get a few styling tweaks which will make the car look more aggressive and some of the design cues will be sourced from the range-topping P1.

It will make its public debut early March at the Geneva Motor Show but McLaren will probably reveal the car online next month. At the moment there aren't any details whether the 650S Spider will receive the same treatment.
