What does shifting an automatic transmission into drive while the car is still rolling into neutral do?

No, doing this won't make your transmission suddenly fall out of the car, or trigger a huge explosion in the engine, despite what some people believe. But, it does put an extra strain on numerous drivetrain components, because you're suddenly slamming the car into drive while everything's moving in the other direction, which can lead to some expensive repairs far earlier.

What's the main point of slotted rotors?

Slotting cut into brake rotors, as well as cross-drilling and also vented rotor designs, are all about shedding heat built up from friction between the brake pads and rotors. They provide the heat with a pathway to escape quickly, like taking the lid off a pot of boiling water, avoiding risks like brake fade.

Why do some race cars zig-zag on the track before a race begins?

When following the pace car, you'll notice many NASCAR, F1 and other racers zig-zag the car, which builds up heat through the extra friction. That heat makes the tires stickier, improving handling, acceleration and even braking performance.

What are wheel chocks for?

Wheel chocks can be made out of a variety of materials, but they're made into a wedge-like shape. One side sits flat on the ground, while another has a tread pattern on it, keeping the tires from slipping, so the car stays stationary when you only have one end on jack stands or ramps.

Why did people have to crank engines manually back in the day?

Back in the day, many cars didn't have a starter like what we benefit from today, so drivers had to use the manual crank to fire up the engine. It wasn't exactly a convenient method, plus sometimes engines would kick back, making the crank move the other direction, which could be dangerous.

What's the first step in taking the wheel off a car, if you're using a tire iron instead of air tools?

The lug nuts on your car's wheels should be tightened quite securely, so loosening them at first requires a bit of force. You can't do that once the car is on a jack, otherwise you risk knocking it off the jack, so loosen the lug nuts slightly, then jack up the car and remove the lug nuts the rest of the way.

How is a twin-turbo system different from a biturbo setup?

While some people may use the two terms interchangeably, in general a twin-turbo system has sequential turbos. That means one is a small turbo that spools up quickly, proving boost a low RPMs, while the second is larger and helps with high-end power. Biturbo setups usually feature two turbos of the same size, but that get their exhaust gases from only half of the cylinders each.

What was the first mass-produced car with electronic fuel injection?

Bosch was a pioneer in electronic fuel injection, which the components producer used successfully in the 1967 Volkswagen 1600, making it the first mass-produced car to use the technology. The improved fuel efficiency became popular during the oil crisis a short time later, and the push for improved vehicle emissions also encourage automakers to use the tech.

Which of the following is a possible cause of a car always having a thick, white exhaust cloud?

When you first start up an engine, the exhaust might appear white, but as you drive and the engine reaches its normal operating temperature, that should no longer be the case. White smoke usually indicates the cylinders are burning coolant, which usually happens because the head gasket is blow, but a cracked block is another possibility.
