If you're trying to heat the inside of your car to make your ride more comfortable you might need to let it run for a few minutes, but your engine is ready to go in 30 seconds or less. According to Triple-A you only need to let your vehicle idle for the time it takes you to fasten your seat belt.

The Minnesota Pollution Control Agency says you don't need to warm your vehicle up unless you're driving a vintage vehicle: “Older cars, with carburetors, did need to warm up. Without warming up, the carburetor didn't get the right mix of air and fuel in the engine — and the car could stall. But in the 1990s, car makers moved from carburetors to electronic fuel injection. Fuel injection sensors supply the engine with just the right blend of fuel and air, preventing stalling in cold weather.”
