When you buy a car, you may be faced with the choice of different warranty options. Knowing the difference between a powertrain coverage and a bumper-to-bumper warranties could help make your choice easier. A powertrain warranty covers the engine, transmission and drive train. It excludes things like the brakes, wheels, windshield, bumpers and catalytic converter.

A bumper-to-bumper warranty covers just about everything on the vehicle. It includes repairs to the exterior mirrors, air conditioning, audio system, doors, engine, transmission, exhaust, brakes, tires and more.
