With a 3.8-liter twin-turbocharged V8 producing 562 horsepower and 443 lb-ft of torque, the McLaren 570S is certainly no slouch. If you want more power, the hotter McLaren 600LT increases the output to a very respectable 592 hp and 457 lb-ft of torque. But if that's somehow still not enough muscle for you, German tuner Pogea Racing has a solution. The aftermarket tuner's latest project is based on the McLaren 570S, but packs even more power than the mighty McLaren 600LT.

By tweaking the ECU and fitting a new exhaust system, Pogea has managed to extract a devilish 666 PS (657 hp) from McLaren's 3.8-liter twin-turbocharged V8. With 95 hp more than the standard 570S and 65 hp more than the 600LT, that's a considerable power bump.

Torque has also increased from 457 lb-ft in the 600LT to 590 lb-ft. Impressively, that's the same level of torque the hardcore McLaren Senna generates.

With these upgrades, Pogea claims the McLaren 666S will hit 0-62 mph in 2.9 seconds, 0-124 mph in 7.9 seconds, and reach a top speed of 207 mph. For comparison, the McLaren 600LT takes 2.8 seconds to do the 0-62 mph sprint and 8.2 seconds to reach 0-124 mph before maxing out at 204 mph. Complementing the performance upgrades are a series of exterior enhancements including new KW V3 coilovers and custom 20-inch tires wrapped in grippy Michelin Pilot Sport 4 tires.

The custom exhaust system also adheres to with Euro6 and TUV compliance in all modes and has new integral insulation to reduce the engine temperature.

Pogea Racing is selling these upgrades for the McLaren 570S as a package that will set you back €11,000 ($12,527) on top of the car's base price. That brings the total to around $205,000, which isn't cheap but still less expensive than the $240,000-McLaren 600LT. McLaren is currently developing a new hybrid Sports Series that will eventually replace the 570S, but the launch has been delayed until 2021.
