Pontiac Solstice Forum - View Single Post - What will the performance difference be between the 5 Speed and the Automatic?

I'd bet the auto will sap some 8-12 rear wheel horsepower due to the rather significant aditional rotational mass. It will probably also add at least another 50-75 pounds to the overall weight of the car. In an otherwise stock large V8 car, GTO, Mustang, Trans Am and the like, the efficiency of the auto can sometimes overcome these two issues and still net similar 0-60 and quater mile times especially when compared against an inexperienced stick driver. On the four banger Sol that can already use a diet and all the free, rear wheel horsepower it can get, I'd expect the auto cars to give up quite a bit in straight line performace.
