How to Use Anti-Lock Brakes (ABS) In an emergency stop, press the brake pedal firmly and steadily and keep steering where you want to go—do not pump the brakes. Expect rapid pulsing or vibrations as the ABS works. On motorcycles with ABS, apply firm, progressive pressure on both brakes while keeping the bike upright and …
How a Gas Pump Knows When to Stop A gas pump nozzle stops automatically because a small sensing hole near its tip is linked to a Venturi-driven vacuum; when rising fuel blocks that hole, the change in vacuum triggers a mechanical valve that instantly cuts off flow with a “click.” This prevents overfilling and spillage. …
What Is the Atkinson Cycle Theory? The Atkinson cycle is a thermodynamic cycle for internal combustion engines that improves fuel efficiency by making the expansion stroke longer than the compression stroke, extracting more work from each combustion event at the cost of peak power. Originating with James Atkinson’s 1880s mechanical linkage engines and implemented today …
What Your Driving Style Reveals About Your Personality Your driving style often mirrors core personality traits—like conscientiousness, agreeableness, and risk tolerance—yet it is also shaped by mood and environment.

How to Tell If a Car Clutch Is Going Bad You can usually spot a failing clutch by symptoms such as rising engine revs without matching acceleration (slipping), a noticeably higher or lower clutch engagement point, difficulty selecting gears, shudder on takeoff, new noises when pressing the pedal, a spongy or heavy pedal, and a …
What Is the Motor on a Car? The motor on a car is the machine that turns energy into motion to drive the wheels—either an internal combustion engine burning fuel or an electric traction motor powered by a battery. In everyday language, “motor” often refers to any car’s main power unit; technically, engines convert chemical …
What the Occupant Classification Sensor Does in Modern Vehicles The occupant classification sensor determines who or what is in a seat—empty, a child seat, a small child, or an adult—and uses that information to enable, disable, or tailor airbag deployment and seat-belt reminders, reducing injury risk and meeting safety regulations. In practice, it’s a key …
What Is the Computer System in a Car Called? It’s most commonly called the Engine Control Unit (ECU) or Engine Control Module (ECM), but modern cars actually use a network of computers—collectively referred to as Electronic Control Units—linked together, with key units like the Powertrain Control Module (PCM), Body Control Module (BCM), and, in electric …
What Do Bikers Call Their Ladies? In traditional motorcycle club culture, many bikers refer to a long-term partner as an “old lady,” but usage varies widely today, and plenty of riders simply say “partner,” “wife,” “girlfriend,” or use a person’s name. The term’s meaning, acceptability, and frequency depend on the subculture, the club, and the …
What a Camshaft Does for Performance A camshaft controls when, how long, and how far an engine’s valves open, directly shaping airflow; by altering lift, duration, and timing (including variable systems), it changes the torque curve and horsepower, often trading low‑rpm drivability and emissions for high‑rpm power with aggressive profiles. This article explains how that …
Can electric cars go faster? Yes—most electric cars accelerate faster than comparable gasoline cars thanks to instant torque, and today’s quickest EVs reach 0–60 mph in under 2 seconds. For top speed, many EVs are software-limited and still trail the very fastest internal-combustion hypercars, but several production EVs now exceed 200 mph, with the Rimac …
What will replace gasoline? The contenders powering the next era of transport There is no single “new fuel” replacing gasoline: electricity is emerging as the primary successor for most passenger vehicles, while hydrogen and low‑carbon liquid fuels (such as ethanol, renewable gasoline, and synthetic e‑fuels) are set to cover harder-to-electrify uses and the vast existing …
Can I replace an O2 sensor myself? Yes—on many vehicles, a DIYer with basic tools can replace an oxygen (O2) sensor in 30–90 minutes, provided the sensor is accessible and not seized by rust. The job involves safely lifting the car, unplugging the old sensor, loosening it with a 22 mm O2 socket, installing the …
How much does a motorsport driver make? It ranges dramatically: from drivers who pay to compete, to mid-tier pros earning about $100,000–$1.5 million per year, to global superstars in Formula 1 exceeding $50 million annually before endorsements. Pay depends on series, team status (factory vs. privateer), results, marketability, and sponsorship, with most full-time professionals clustered …
How Salvage Title Insurance Works You generally can’t insure a vehicle with a “salvage” title for road use; after it’s repaired and passes a state inspection to become a “rebuilt” (or reconstructed) title, most insurers will sell liability coverage, while collision and comprehensive are often limited, costlier, or unavailable, and claim payouts are based on …
What a Stabilizer Bar Does—and Why It Matters for Handling and Safety A stabilizer bar—also called a sway bar or anti-roll bar—connects the left and right suspension on an axle and resists body roll in turns by twisting like a torsion spring, keeping the vehicle flatter and steering more predictable; in helicopters, a similarly named …
Symptoms of a Bad Brake Booster A failing brake booster typically causes a hard brake pedal that requires much more effort, longer stopping distances, a hissing sound when you press the pedal, and sometimes rough idle or stalling when braking. In many cases, the pedal feels high and stiff, especially at idle or during acceleration, …
What Is the Gearbox of an Automatic Transmission? The gearbox in an automatic transmission is the assembly of gearsets—most commonly planetary gearsets—plus clutches and brakes that change gear ratios automatically under electronic and hydraulic control. In practical terms, it’s the part inside the transmission that actually creates and switches between the “gears,” working with a …
How a Solar Car Works: Turning Sunlight into Motion A solar car captures sunlight with photovoltaic panels, converts it to electricity via power electronics, stores it in a battery, and delivers it to an efficient electric motor to drive the wheels; smart controls balance solar input, battery state, and driving demand to keep the vehicle …
Is a Brake System Flush Worth It? Generally yes—if your vehicle is due by time/mileage, or testing shows contaminated fluid, a brake system flush is a worthwhile, relatively low-cost service that preserves braking performance and prevents expensive ABS and hydraulic component damage. If your owner’s manual says “inspect” rather than “replace,” ask for a moisture/boiling-point …
What Is the Front Suspension? The front suspension is the assembly that connects a vehicle’s front wheels to its frame or body, allowing controlled up‑and‑down movement to maintain tire contact, absorb bumps, and stabilize steering. In cars, motorcycles, bicycles, and heavy vehicles alike, the front suspension shapes ride comfort, handling, braking stability, and safety. Core …
Why It’s Called “Cali Lean” It’s called “Cali Lean” because “Cali” signals a California-born aesthetic and culture, while “lean” describes either a visible tilt or rake (in automotive styling) or a syrup-like drink inspired by hip-hop slang; together, the phrase evokes a West Coast look or vibe that deliberately “leans” from the norm. The term …
Do Manual Transmissions Last Longer? Generally, no—manual transmissions don’t automatically last longer than automatics today. Modern torque‑converter automatics can match or exceed a manual’s lifespan if serviced properly, while manuals still benefit from mechanical simplicity but depend on clutch wear and driver technique. Longevity now hinges more on design, maintenance, heat management, and how the …
How long do stock suspensions last? They can last anywhere from about 5 minutes (for routine volatility pauses) to 15 minutes (for market-wide circuit breakers), a few minutes to several hours (for news-related halts), up to 10 business days (for an SEC regulatory suspension), and potentially months or indefinitely if an exchange suspends a listing …
