Ever mash the throttle of a front-wheel-drive car, only to feel the steering wheel seemingly get yanked out of your hands as the car makes a beeline for the edge of the road? That’s torque steer. Take the dreaded phenomenon of torque steer, for instance. If there are any faults with front-wheel drive, it’s with issues concerning grip and performance. With less heavy componentry to tote around and fewer mechanical parts to send power through, the front-drive car will usually eke out an extra one or two miles per gallon compared to its equivalent all-wheel drive model. For anyone who isn’t a race car driver, this is the easier situation to deal with, as there’s no risk that the rear end will snap around and send you spinning.Ĭompared to all-wheel drive, a front-wheel drive vehicle will return better fuel economy in just about every instance. When it happens it feels like you’re plowing into a corner. In most instances, a front-drive car that enters a corner too fast succumbs to understeer – a condition in which the car turns less than you’d like.
This scenario is far less likely with front-wheel drive.
During such a slide the rear end gets light and can come around quickly, resulting in oversteer and a full 360-degree spin, if you’re not careful, though the standard traction control on modern cars can sometimes prevent this. At that point the tires lose their grip and start sliding. If you lose control in a rear-drive car, it usually means the rear tires lost traction – in other words, more power was sent to the tires than they could handle. The result is a roomier cabin, lighter weight and lower energy/drivetrain losses between the engine and driven wheels.įWD is also a safer option than rear-wheel drive (RWD), the reason being its behavior at the limits of grip. By eliminating these components you can have a flat interior floor and a lower cargo hold. A front-drive car doesn’t need a longitudinal transmission, driveshaft, or rear differential, all of which are necessary for rear-wheel drive as well as some all-wheel drive cars. One reason why this design has become the preferred layout for modern cars is because it is inherently fuel efficient while offering more cost-effective packaging and superior space utilization. The transaxle ultimately routes the power to the two front wheels. Before reaching the wheels, the power is first sent to a transaxle, which is a part that acts as a sort of combination transmission and differential. I have the public variables set to 5 (acceleration) and 3 (steering).FWD is exactly what it sounds like: the front wheels act as the driven wheels, or the wheels that get the power from the engine. I know it's far too late, but I used the $$anonymous$$nts above to create the following script, please excuse the verbose syntax.
