Renntech SLR McLaren 722 PKG2

When Mercedes decided that it’s time to boost the engine power for this lovely SLR supercar they created the limited edition SLR722. A lot of people thought that 722 comes from the power developed by the 5.5L V8 engine of this car while others thought that there will be built only 722 cars like this one. But they were all wrong. In fact the car’s name comes from the Mille Miglia from 1955 where Stirling Moss and Denis Jenkinson won with a Mercedes-Benz 300SLR in front of race favorties like Ferrari and Porsche. The car had the racing number 722 which was the exact hour of race start 7:22 am.

Last year, the car tuning company Renntech ended this confusion and boosted this car’s power from the initial 650 HP to 722 HP. The PKG1 kit included new intercoolers and modified engine cooling unit that will add this slight boost of power.

With this extra power this car will accelerate from 0 to 100 km/h in less than 4 seconds and it will reach a top speed of over 300 km/h.
