Which cars don’t have a clutch? Any car without a manual transmission lacks a clutch pedal—this includes nearly all automatics, most hybrids, and every battery‑electric vehicle. In everyday terms, if a car is labeled automatic, CVT, DCT, e‑CVT, or electric, you won’t be operating a clutch. Below, we explain the difference between having no clutch …
How a Car’s Speed Limiter Works A car’s speed limiter caps vehicle speed by using the engine control unit to restrict engine torque—typically by moderating the electronic throttle and, when needed, fuel and spark—once a set threshold is reached; in newer “intelligent” systems, cameras and GPS maps recognize posted speed limits and can warn the …
Stiff Steering: What It Means and What To Do If your steering suddenly goes stiff, it usually means you’ve lost power-assisted steering or something is physically binding in the steering or suspension, which is a safety risk and should be checked immediately. In most cases the culprit is low power-steering fluid, a failing pump or …
Is the brake pedal in the middle? Yes—in vehicles with a manual transmission, the brake pedal is typically the middle pedal between the clutch and the accelerator. In most automatic-transmission cars, there are only two pedals; the brake is on the left and the accelerator on the right, so the brake is not literally “in …
What does a 2.0-liter engine mean? A 2.0-liter engine refers to the engine’s total displacement—the combined volume swept by all pistons inside the cylinders—of roughly 2,000 cubic centimeters (cc), or about 122 cubic inches. It describes engine size, not power; two 2.0-liter engines can deliver very different performance depending on design, turbocharging, and tuning. What …

Why trucks are called “1-ton” — where the name came from and what it means today They call a truck a “1-ton” because, historically, it meant the vehicle could carry roughly one short ton—2,000 pounds—of payload. Today, the term survives as a size/class label (typically the 350/3500 series of heavy-duty pickups) rather than a precise …
Is it bad to drive with white smoke from the exhaust? Generally, yes—driving with persistent, thick white smoke is risky and should be avoided. Brief, thin white vapor on a cold start that quickly dissipates is usually just condensation and is normal. But continuous white smoke often means coolant is entering the combustion chamber, which …
Does banging on an alternator work? Mostly no. A gentle tap might briefly restore charging only if the alternator’s worn brushes are sticking, but it’s unreliable, easy to confuse with the old “tap the starter” trick, and can damage modern alternators.
