Does the supercharged engine make a big difference in speed compared to bonnevilles without it
I'll give you a few specs for the SSEi and the SE(base) models. Horsepower: SSEi - 240/ SE - 205. Torque: SSEi - 280 ft-lbs/ SE - 203 ft/lbs. The SSEi does have a better braking distance too but has worse gas mileage (17city/25hwy.) Bottom line the SSEi does 0-60 in 7.1 seconds, the SE does 0-60 in 8.3 seconds. So yes it does make a big difference.
