Mercedes might develop another super car working once again with McLaren. The Mercedes McLaren Mini SLR will have a 5 liter V8 engine that will push some 400 horsepower. It will supposedly reach top speeds beyond that of the SL65 due to its light body weight and might even beat it in a 0-60 race. While that might be a small engine it will still be marketed as a super car like the McLaren SLR. Currently the McLaren SLR pushes 626 horsepower. Still a concept right now.
