Mercedes' uber sports car, the McLaren SLR 722 GT, has been caught at the 'ring undergoing final testing for the 20-odd cars that are expected to be delivered to a very lucky few early next year. A pre-production model was spotted at the start of the month in Germany and this is likely to be the same car seen here.
We know that Mercedes used the SLR 722 badge on the SLR McLaren 722 Edition to honor the 1955 Mille Miglia-winning Mercedes-Benz 300SLR of Stirling Moss and Denis Jenkinson, but still. That car, wearing a big "722" on the doors, which indicated their 7:22am start time, managed to beat the favored Porsches and Ferraris back in the day. But people see a 722 on the label and somehow 650 hp doesn't seem good enough. Enter, supertuner Renntech.
