🔧 Build & Race Workshop
Build it, then find out if it works: pick a body, an engine and tyres, and race on tracks that each want a different car!
How to play
- In the workshop, choose a body, an engine and a set of tyres. Your car turns on the stand and the bars show how it should drive.
- Choose a paint colour and a track. The track card tells you the surface: tarmac, dirt or snow.
- Press Take it for a race. When the lights go green, hold W or ↑ (GAS) and steer with A and D or ← and →.
- Press S or ↓ to brake, and hold Space (SLIDE) to swing round tight corners.
- If your car struggles, the game will tell you why at the end of the race.
- Go back to the workshop, change a part and try again.
- Win for 3 stars, reach the podium for 2 or finish for 1. Stars unlock better parts.
A car building game where your choices really count
Plenty of car building games let you choose a colour and some wheels, and then every car drives the same. Build & Race Workshop does the opposite. Every part you bolt on changes how your car accelerates, grips, turns and stops, and you can feel the difference the moment the lights go green. Fit a giant engine to a tiny frame and you will have a rocket that is very hard to keep on the road. Put racing slicks on for the snow track and you will spend the whole race sliding gently off the road.
It plays in full 3D in your web browser on a computer, tablet or phone, with nothing to download and no account. You can go from idea to finish line in about two minutes, and that is the whole point: build, race, learn something, and go back and build again.
The workshop
You choose three things. The body sets your car's weight and shape. The engine sets your power and your top speed. The tyres set how much grip you have, and on what. Your car turns slowly on the workshop stand so you can see what you have made, with a set of bars beside it for top speed, acceleration, grip and turning, braking and weight. Change a part and the bars move at once. Pick a paint colour to finish it off.
Weight is the hidden part
The most important number in the workshop is the one you do not choose directly. Every part adds weight, and weight makes a car slower to speed up, worse at turning and worse at stopping. That is why the biggest engine is not always the best one. On a long straight the Rocket V8 is unbeatable, but on a narrow track full of corners, a lighter engine may get round a lap much more quickly because it does not have to brake so early. Real race engineers argue about exactly this every day.
The parts
Bodies: the Go-Kart Frame is tiny and light, and turns on a coin, but it cannot reach the highest speeds. The Rally Shell is a good all-rounder and is happy on loose roads. The GT Coupe has a slippery shape that adds top speed on tarmac. The Dune Buggy is heavy, but grips well on dirt and snow.
Engines: the Mower Motor is gentle, light and easy to control, and is great if you are just learning. The Street Four is a solid everyday engine. The Turbo Six has plenty of power but adds some weight, and the Rocket V8 has huge speed and is hard to stop.
Tyres: Road Tyres are good on tarmac and poor elsewhere. Knobbly Tyres dig into dirt and snow but lose grip on tarmac. Racing Slicks are amazing on tarmac and awful anywhere else. All-Terrain tyres are good on everything and the best at nothing.
Six tracks, six different cars
The tracks are where you put your build to the test, and no single car is best on all of them. Test Track is wide, easy tarmac for trying things out. Dirt Farm is your first dirt race, and road tyres will not last long here. Harbour Sprint has very long straights that reward a big engine. Snow Pass is slippery, and a light car on good tyres is a real help. Quarry Jumps mixes dirt with tight bends and three big jumps. Finally, Grand Test is a fast tarmac race at night against the quickest rivals in the game.
The game warns you before the start if your tyres do not suit the surface. If you come home behind the winner, the result screen gives you a tip about what to change.
Stars unlock better parts
Win a race for three stars, finish on the podium for two, or simply finish for one. Your best result on each track counts, for eighteen stars in all. You start with two choices in each slot: the Go-Kart Frame and Rally Shell, the Mower Motor and Street Four, and Road and Knobbly tyres. Three stars unlock Racing Slicks, four the GT Coupe, six the Turbo Six and eight the Dune Buggy. Nine stars unlock All-Terrain tyres, and twelve unlock the mighty Rocket V8. Your build and your stars are saved in your browser on this device.
Builds to try
For a first race, try the Rally Shell, Street Four and Road Tyres. It is easy to drive and quick enough to win the Test Track. For dirt and snow, swap to Knobbly Tyres straight away, and try the Go-Kart Frame if you keep sliding wide, because its low weight does a lot to help.
Once you have earned a few stars, try something silly as well. A Go-Kart Frame with a Rocket V8 is frightening and very fast. A Dune Buggy with a Mower Motor is the slowest thing in the game. A failed experiment only costs you one race, and you often learn more from it than you do from a win.
Can I play this car building game at school?
Build & Race Workshop runs in any modern browser with no download, which is why people look for it as an unblocked car game. Whether it opens on a school or work network depends on that network's filter, so we cannot promise it will always be unblocked.

Once you have mastered car setup, try the pit stops and tyre wear in Sim Racing Circuit 3D, or take a tiny car round a giant house in RC Car Racing 3D. You can find them all on our racing games page.
Frequently asked questions
Do the parts really change how the car drives?
Yes. Engine power, body shape, weight and tyre grip all feed into how the car accelerates, turns, brakes and slides. The same car can be great on one track and hopeless on another.
What is the best build?
There is not one. Racing Slicks and a big engine are best on open tarmac, while light cars on Knobbly Tyres work better on dirt and snow. Part of the fun is finding out what suits each track.
Which tyres should I use on snow?
Knobbly Tyres or All-Terrain tyres. Racing Slicks have very little grip on snow, and the game warns you before the race if your tyres do not suit the surface.
How do I unlock more parts?
Earn stars: 3 for a win, 2 for the podium and 1 for finishing. New parts unlock at 3, 4, 6, 8, 9 and 12 stars.
Can I change my car between races?
Yes, as often as you like and for free. Press Garage after a race to go back to the workshop.
Is this game unblocked?
It runs in your browser with no download, but whether it opens at school or work depends on that network's filter, so we cannot promise it. If anonarcade.com opens, the game will work.
Does it work on phones and tablets?
Yes. The workshop works by tapping, and the race has on-screen steering, gas, brake and slide buttons. It is free, with no sign-up.
