McLaren SLR 722 GTB by Sievers presented at Essen image

The aftermarket specialists at Severs have hit the 2011 Essen Motor Show with a special creation based on the McLaren SLR 722 Edition, here fitted with a new aggressive body kit and given an impressive power boost.

Even if you can see two McLaren SLRs in the video above, health we’ll talk about the orange one which, according to the uploader of the video on YouTube, is 100 percent street legal and its engine is now developing a total output of 814 horsepower. Sadly we don’t have any official details about the supercar’s performance but according to the CEO of Sievers, the top speed should be over 350 km/h. Don’t get too excited on this because if you want to buy the unique orange beast you should pay 1.9 million euros, so unless you can afford that, you might want to settle for the video below.

As a reminder, the Mercedes-Ben SLR McLaren has been developed by Mercedes-Benz and McLaren Automotive, built in Portsmouth and Woking, England, being sold from 2003 to 2009. The base price of the car when it was in production has been set at 350.000 EUR or 450.000 USD, making it in that time the ninth most expensive street-legal car in the year 2008. The SLR with its 5.4 liter supercharged V8 engine, mated to a five-speed automatic transmission, was developing 617 horsepower at 6.500 rpm and 780 Nm (580 lb-f) between 3.250 and 5.000 rpm.
