A.kirby is out to lunch. Capiche? It is all to do with the rear end ratio. The lower the ratio, the more horsepower it will take to match the acceleration of a vehicle with a higher numbered ratio. Police interceptors are likely to have a 2.53 ratio and a Camero is likely to have 3.80 or 4.11 rear end ratios. The Camero will leave the interceptor behind at the start but can never beat it for top end speed. At highway speeds your lower ratio would have your engine running at a slightly lower rpm which translates into better fuel mileage, but sacrifices get up and go. If you live live in really hilly terrain and have to pull a lot of hills you would want a higher numbered ratio as that allows for better performance in the hills. Higher ratios can be used by car makers to give better acceleration from less horsepower engines because it takes less horsepower to make the vehicle accelerate quicker like it felt in the Limited you drove. ABSOLUTELY NOTHING TO DO WITH HEAVIER WHEELS....
