Upgrade the CARS is a 3D driving game where every gate you pass makes your ride better — or worse. Steer your car through the green plus gates to boost your engine, body and speed, and dodge the red minus ones that strip your upgrades away. Reach the end of the track with the strongest car you can build, then cash it in. Spend your earnings on new parking spots, unlock fresh cars in the garage, and repaint them in the texture shop. Every run funds the next one. Push far enough and the road stops being empty — giant kaiju block the way, and you will need weapons to clear them. Collect money on every lap
