What It Means When a Car Is Turbocharged A turbocharged car uses a turbine driven by exhaust gases to compress the incoming air, forcing more oxygen into the engine so it can burn more fuel and produce more power from a smaller displacement. In everyday terms, a turbo adds performance without necessarily increasing engine size, …
Driving on the Left: What It Means and Why It Matters Driving on the left means vehicles keep to the left-hand side of the roadway, drivers typically sit on the right side of the car, overtakes happen on the right, and roundabouts generally circulate clockwise. The practice—often called left-hand traffic (LHT)—is used in dozens of …
Common Cars of the 1950s: From Mainstream American Sedans to Global People’s Cars In the 1950s, the Chevrolet Bel Air in the United States and the Volkswagen Beetle globally were among the most common cars; depending on the country, everyday sights also included the Ford Fairlane, Morris Minor, Citroën 2CV, Fiat 600, and Opel Rekord. …
Why your car makes a noise when you’re in reverse Most reverse-only noises come from normal gear whine or brake-related sounds, but they can also signal issues like a worn CV joint, a dragging parking brake, loose hardware, or a failing mount. Pinpointing the sound—whine, squeal, click, clunk, or grind—and when it happens (cold start, …
Who invented the Wankel rotary engine? The Wankel rotary engine was invented by German engineer Felix Wankel. He conceived the idea in the late 1920s, patented key concepts in 1929, and—working with the German automaker NSU—saw the first running prototype (the DKM 54) fire up in 1957, paving the way for later production versions used …

What Happens If I Top Off My Tank? Topping off your gas tank after the pump clicks off can push fuel into your car’s evaporative emissions system, trigger a check-engine light, damage the charcoal canister, waste money through spills, and increase fire and pollution risks; the best practice is to stop at the first click. …
Is a timing light necessary? It depends: for most modern, computer-controlled engines, a timing light isn’t necessary because ignition timing isn’t adjustable; for older vehicles with a distributor or engines that require base-timing verification, a timing light is the right—and often essential—tool. Below, we explain when you need one, when you don’t, and how to …
What to Do When Your Steering Wheel Is Hard to Turn If your steering wheel suddenly becomes hard to turn, slow down and pull over safely, check tire pressures and (if equipped) power steering fluid, look for belt damage or leaks, and avoid driving if the wheel feels dangerously heavy or you hear grinding or …
HEMI vs. “Regular” Engines: What Really Sets Them Apart A HEMI engine uses a (roughly) hemispherical combustion chamber that places the valves at wide angles and the spark plug near the center, while most “regular” modern engines use flatter or pent-roof chambers with four smaller valves per cylinder. This difference in chamber shape and valve …
