The Mechanics of Modern Cars

Understand how modern cars translate mechanical forces into motion, handling, and control. Learn the physics of tire grip, power delivery, drivetrain layouts, and how to read the diagnostic cues your vehicle sends through the controls.

Like Duolingo, but for The Mechanics of Modern Cars. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through The Physics of the Driver's Seat and Chassis, Drivetrains, and Diagnostic Feel. It assumes you already know the basics.

Key ideas in The Mechanics of Modern Cars

  • A tire has a finite total friction budget split between turning and stopping.
  • Demanding maximum braking and maximum cornering simultaneously breaks traction.
  • Trail braking requires trailing off brake pressure as steering angle increases.
  • Deceleration compresses the front suspension and loads the front contact patches.
  • Increased vertical load on front tires raises their available cornering grip.
  • Unloading the rear axle makes the rear lighter and more prone to rotating.
  • Acceleration transfers vehicle weight rearward, unloading the front tires.
  • FWD cars lose front steering grip under power because the drive tires are unloaded.
  • RWD cars overwork the rear tires under throttle, triggering power oversteer.
  • Snapping off the throttle shifts load forward and unweights the rear tires.
  • A suddenly unweighted rear tire loses lateral grip while already loaded in a bend.
  • Lift-off oversteer pivots the rear of the car outward toward the outside wall.
  • Progressive inputs give suspension dampers time to control chassis movement.
  • Abrupt dynamic inputs spike load instantly and exceed peak tire grip thresholds.
  • How drivetrain layout dictates vehicle reaction under hard corner-exit acceleration
  • Smooth transitions maximize the tire contact patch without shock-loading it.
