Funny Ford Mustang Fails Compilation
The classic Mustang from the seventies was a sexy muscle car that combined a great look with lots of power. The nineties version was a fancy Ford Escort. Unfortunately the nineties version also introduced the 5.0-liter version of the Mustang, the one with the obnoxious rear spoiler. This was the one Vanilla Ice rapped about. Since, Ford has tried to recreate the seventies, but has ended up back in the nineties. Anyone driving one of these cars (bonus points if it’s a nineties 5.0) might as well roll down the windows and blast “Ice Ice Baby.” It was obnoxious then and is now both obnoxious and dated. (Super douchebag bonus for anyone caught in one of these “rolling” down Ocean Drive in Miami.
The primary purpose of the differential is to allow the wheels to rotate at different speeds. Differentials take the power sent from the engine and translates it (from the driveshaft and via specially oriented gears) into rotational motion at the wheels. Furthermore, it allows each driven wheel to turn at different speeds which is necessary for a corner.
This is particularly important when turning. When going around a corner, the outer wheels actually need to turn faster to complete the turn at the same rate as the inner wheels. This is because the outer wheels have a larger circumference to travel (the radius, the outer wheel distance, is longer from the center of the turn) and to complete this longer turn in the same amount of time, need to turn faster. A differential allows for exactly this - the inner and outer wheel to turn at different speeds and therefore creating a nice, smooth turn.
Furthermore, as hinted above, a differential helps with the traction of the Mustang. Differentials can manage torque such that if one wheel is slipping, it lessens the torque going to the slipping wheel and instead applies it to the wheel with traction.
Since Mustangs are rear-wheel drive, the differential is located underneath the rear of the car between the wheels. The purposes of differentials are as follows:
Transmit the engine power to the wheels
Act as a final gear reduction from the transmission to the wheels
Allow each wheel to spin at different speeds
An open (basic) differential has no way to control the amount of torque being sent to each wheel. Instead, it just splits the torque evenly. It's not able to distinguish if one wheel has less or more traction. This is important and will be addressed a bit further down. Open differentials came standard on V6 models until 2011 and on V8 models until 1986.
