Are the cars real models?

No, they are plain geometric shapes — no brands.

Yes, after the first open it runs without a connection.

In Topdown Racer you keep your speed through the corners and stay on the track. Three clean laps finish the run.

Steer the car
Turn to follow the track and avoid running off the edge.
Manage speed
Slow a little for tight corners, accelerate on the straights.
Steering tightens with speed
Turn authority grows with speed, so a fast car needs a longer line than a slow one. Steering hard at low speed does almost nothing at all.
Three laps is the run
The score is laps completed, so going backwards around the loop costs you progress rather than adding to it. Three laps ends the run.
Steering authority rises with speed
Left and right rotate your heading instead of sliding you sideways, and the car answers the wheel only in proportion to how fast it is rolling, so a crawling car barely turns at all. Grass outside the oval is a hard speed limit and bleeds momentum every frame.
Laps run both ways
Laps are tallied from how far you travel around the centre of the oval, so reversing unwinds the counter rather than banking it. Three laps ends the race, and the three opponents on track drive through you without any contact.

Never stop on the ring
The car steers in proportion to how fast it is travelling, so a car that has slowed to a crawl on the inside grass will not turn at all and cannot get going again on it. Keep the accelerator down through the whole bend. The three opponents never brake either, so stopping anywhere puts them ahead of you and there is no shortcut back through them.
The inside grass is a dead end
Off the track your speed is capped at roughly a third of what the road allows and it bleeds away every frame, so cutting the corner across the middle loses far more than it looks like it saves. The ring is continuous, so there is always a route that stays on the road. Take the outside line and stay on the surface rather than aiming at the middle every lap.
Laps count progress, not position
A lap is only counted once you have turned all the way around the centre, and turning back the other way hands the progress straight back. So a spin on the inside grass does not merely slow you down, it can take a lap you had already earned. Hold one direction through the bend and drive away from problems rather than steering back to recover.
