The drag race simulator with real physics. Race any car, tune it, and take on daily challenges.

Hybrids and multi-motor EVs now add up every motor and engine at each speed, so their listed horsepower is accurate.

A tuning season: set your own final drive ratio, add aero on select boards, and tied runs now share a rank. Try it →

Head-start races now time each car from its own start line, so rollout, 60 ft and every split are measured the same way for both lanes.

Every badge in your Paint Booth shows how many racers hold it, and your Driver Card shows your rarest one. Try it →

Belt-drive CVTs now launch through a torque converter and are limited by how much torque the belt can carry, for more accurate launches.

On a rolling start, every engine now begins at the rpm its gear and speed call for, with automatics starting in sync with their torque converter.

Race results now lead with who won and by how much, then suggest your next race.

Send your challenge run to a friend: they race against it as a ghost and can send their run back. Try it →

Pick your racing number and wear the liveries and decals you earn in challenges on every board and share card. Try it →

Fit parts from headers to blow-off valves and hear each one change the engine note. Free players can preview every part. Try it →

Cars shift just before redline like a real driver, dual-clutch cars launch without endless clutch slip, and speed limiters hold the car at its cap instead of cutting power on and off.

Electric motors in hybrids now help during the launch and share each axle's grip with the engine.

Carbureted classics idle rough and backfire, Hondas hit VTEC at the real crossover, and the Mazda 787B gets its rotary scream.

Finish a challenge season in the top 10, 25 or 50 percent and keep a mark in your Medal Cabinet for good. Try it →

The homepage plays a real simulated race between two cars, one tap away from racing them yourself.

Cars now upshift when the next gear pulls harder instead of waiting for redline, so they no longer get stuck in a lower gear short of their real top speed.

The winner is whoever crosses the finish line first, like a real drag race; elapsed time stays on the timeslip, so a head start or a better launch can win.

Daily and weekly build puzzles: build a car within the rules, lock in your best run and climb the season standings. Try it →

Turn traction control off before any race; Premium adds launch RPM and three launch styles.

Every race now models tire slip: each driven tire's grip depends on how much it slips and how much weight is on it, so too much power spins the tires instead of hooking up perfectly.

0-60 and 0-100 times now use the 1-foot rollout that magazines and manufacturers publish, on every screen.

Premium members got first access to daily and weekly build challenges.

The race temperature setting now changes tire grip: drag slicks work best in a narrow window, while performance street tires hold up in the heat.

Add Motor Matchup to your home screen on Android and it opens like an app.

Weight reduction gets a slider, and tires come in compound tiers with a grip comparison. Try it →

Motorcycles can race, and new Fastest Cars lists rank the quickest cars by category. Try it →

Paint your build any color, and Beat This Car finds cars that are quicker to 60 and cost less than the one you pick. Try it →

CVT cars now change ratio continuously to hold the engine near peak power, instead of racing through fixed gears.

Engines bounce off the rev limiter, V8s lope at idle, and every cylinder sounds a little different.

Races show each car as a side-view sprite of the real thing instead of a generic shape.

Find any of 50,000+ vehicles faster, with redesigned spec pages.

Races play engine sound, with a redesigned tach and race screen.
