Front vs. Rear Wheel Drive
By Kevin
Over the lion's share of the automobile's history, most cars had an internal-combustion engine in front of the driver powering the wheels in back of him. But the fuel crises of the 1970s changed that. Manufacturers scrambled to save weight to save fuel, and they adopted assorted variations of the front-engine/front-drive layout...Popular mechanics performs a matched-pair experiment on a set of V-4, V-6, and V-8 powered cars:Lately there has been a resurgence of rear-wheel-drive family cars. And, their makers claim better traction and handling than front-drive models, thanks to sophisticated electronics...
One in each pair had front-wheel drive, the other rear. We ran them through our normal battery of performance tests. Then, we soaked the track and repeated all the tests to replicate the conditions you would face on a rain-slick road.
The reviewers conclude that computer control has eliminated the expected difference in power and handling between front and real drive:
Neither front-wheel drive nor rear-wheel drive is really better than the other. Today's sophisticated traction and stability control systems are so good they can mask or enhance the true driving dynamics of a vehicle. That said, through most of this test we found the effectiveness of these systems had more to do with a car's performance than which wheels were actually doing the driving.One could quibble over the sample size of the test--in terms of cars and drivers--and insist that there must be some difference, but that would miss the point. Computers have made the difference between front and rear wheel drive so small that finding its exact level, or range of levels, is a waste of time...
