Have you ever seen a front wheel drive car making a one wheel burnout? You have? Great! That’s the problem many manufacturers have been trying to circumnavigate or completely resolve on FWD cars. Not so much to deter you from making one wheel burnouts, but to make the car corner better and safer with putting down the power to the wheel that actually has some grip. The reason a FWD car (or any car for that matter) tends to send power to the wheel with least grip is the so-called open differential - a system designed to send power to the wheel with 50 percent of power reaching one wheel and 50 percent the other. However, as opposite wheels on cars must spin at different rates (like when cornering), the open differential cannot be locked, thus allowing for some extreme tendencies to send the power through the path of least resistance. Simply said - to the wheels with the least grip. Using this system saves a ton in R&D, the simple design of open differential makes it cheap to produce, and it doesn’t put too much strain on the various drivetrain elements. However, some tend to make fun of open diffs. “They are just like a one-wheel drive.” Is there any truth to this? After all, the power always goes to the wheel with the least resistance.
