Well, no. If you rev your engine in neutral, then drop the gear lever into D while the engine is revved high, you aren’t going to go fast—you’re going to violently and catastrophically break important stuff, and at best limp away from the line and coast to a stop, beaten and embarrassed.

What happens if you rev your car too much?

If an engine goes overspeed, commonly called “over-revving”, damage to the piston and valvetrain may occur when a valve stays open longer than usual. Valve float can possibly result in loss of compression, misfire, or a valve and piston colliding with each other.

Is it bad to start your car and drive right away?

Warming up your car in winter before driving it is actually terrible for your engine. According to Popular Mechanics, driving your car right away is the fastest way to warm up your engine, and will actually prolong the life of your engine instead of letting it sit idly before driving.
