Every lesson now earns you a car card. • Collectible car cards: pass a lesson's quiz to unlock its car as a playing card with real specs: power, torque, powertrain and drive. Share any card in a tap. • The Garage is now Cards: your whole collection in one place. • A 2026 lineup: discontinued cars are swapped for current models, with all-new artwork and updated descriptions. • A rebuilt Learn tab: see the next car you can earn and what it takes, with each lesson's car shown along your path. • Weekly Car Facts, Explained: short car stories on Home covering race weekends, new metal and everyday driving, each with a quick check and a link to the lesson behind it. It replaces the Daily Gearhead. • Garage Pass: the free trial now comes with the yearly plan, and during the trial you can open the first lesson of every topic. • Better diagrams: they keep their full shape, and you can tap one to open it full screen and pinch to zoom. • Faster-loading lesson images. • Tell us whether a lesson was clear, right from the quiz results. • A refreshed Profile with your collection and Garage Pass details. • Bug fixes and polish.
Stop nodding along when people talk about cars. PistonPath teaches you how engines, transmissions, brakes, and every major car system actually works - through bite-sized illustrated lessons you can finish in just 3 minutes a day. It's the easiest way to learn car mechanics from scratch. Whether you're a complete beginner who doesn't know a spark plug from a lug nut, or someone who wants to finally understand what's under the hood before your next trip to the mechanic, PistonPath turns complex automotive engineering into visual, intuitive, gamified learning that actually sticks - from combustion engines and dashboard diagnostics to electric and hybrid cars. What You'll Learn: • How a 4-stroke engine works (suck, squeeze, bang, blow) • Pistons, crankshafts, and how the combustion cycle creates power • Ignition systems, spark plugs, and engine timing • Lubrication, oil filters, and why viscosity matters • Air intake, throttle bodies, and how an engine breathes • Fuel systems, injectors, the air-fuel ratio, exhaust, and catalytic converters • Forced induction - turbochargers vs superchargers, intercoolers, wastegates, and boost • Clutches, transmissions, and manual vs automatic • Modern gearboxes - CVTs, dual-clutch, planetary gearsets, and launch control • Differentials and cornering physics • Disc and drum brakes, hydraulic power, steering, suspension, and anti-roll bars • Batteries, alternators, ECUs, and the car's nervous system • Engine cooling - radiators, thermostats, water pumps, and coolant • Electric & hybrid cars - EV motors, battery packs, and regenerative braking • Tire grip, the contact patch, FWD vs RWD vs AWD, traction control, ABS, and electronic stability control • Aerodynamics - drag, downforce, wings, splitters, diffusers, and ground effect • Performance & dynamics - torque vs horsepower, power-to-weight, weight transfer, and wheel alignment • Engine layouts - inline, V, boxer, and rotary, and why each one sounds different • Cylinders and displacement - bore, stroke, firing order, and what "2.0-liter" actually means • Motorsport tech - F1 hybrid power, DRS, tire strategy, and carbon brakes • Dashboard warning lights - which ones mean pull over now, and which can wait • OBD-II trouble codes - how to scan your own car and read what it's telling you • Fluids, tire and brake checks - oil, coolant, brake fluid, tread depth, pressure, wear indicators, and service intervals How It Works: • Modules across all systems: Engine Basics, Air & Fuel, Drivetrain, Control & Comfort, Electrical, Cooling & Climate, Electric & Hybrid, Tires & Traction, Forced Induction, Performance & Dynamics, Engine Configurations, Read Your Car, Aerodynamics, Modern Transmissions, and Motorsport Tech • Bite-sized card-based lessons with clear illustrations • Interactive quizzes after every module to test what stuck • Weekly Car Facts for every gearhead, each with a quick challenge • Collect a real car card for every lesson you finish - build a garage of street cars to hypercars and share your cards Perfect For: • Complete beginners who want to learn how cars work without feeling overwhelmed • DIY enthusiasts planning to wrench on their own car • F1, Rally, and motorsports fans who want to follow what commentators are saying • Drivers curious about electric and hybrid cars • Anyone buying a used car who doesn't want to get scammed at the dealership • Future mechanics and students getting a head start on automotive basics • Anyone who's ever ignored a warning light with no idea what it meant Why PistonPath Works: • 3-minute daily lessons designed for busy schedules • Gamified learning with collectible car cards as rewards • No prior car knowledge or auto repair experience needed - start from zero • New modules keep landing - Aerodynamics, Modern Transmissions and Motorsport Tech Download PistonPath and start actually understanding your car today.
