Power-to-weight ratio is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance.
AC Propulsion is a San Dimas, California, USA company founded in 1992 by Alan Cocconi, Wally Rippel, and Paul Carosa, that specializes in alternating current-based drivetrain systems for electric vehicles. It offers AC-induction traction motors. The company produces electric vehicle drive systems featuring high performance, high efficiency induction motors and integrated high power battery charging.

The tZero is a hand-built electric sports car designed and built in very limited numbers by the U.S. pioneering company AC Propulsion in the mid 1990's. It was the inspiration and direct predecessor of the Tesla line of electric cars. The only part of the tZero that was not proprietary was the body that was based on the Piontek Sportech sports car, yet many parts of the body and interior were extensively modified. It consists of a Kevlar & Carbon Fiber reinforced body built over a custom hand-built reinforced stainless steel fabricated to package batteries space frame with double wishbone independent suspension and rack and pinion steering. AC Propulsion utilized their AC-150 drivetrain, a single-speed electric system with an overall gear ratio of 9:1.

The energy efficiency in transport is the useful travelled distance, of passengers, goods or any type of load; divided by the total energy put into the transport propulsion means. The energy input might be rendered in several different types depending on the type of propulsion, and normally such energy is presented in liquid fuels, electrical energy or food energy. The energy efficiency is also occasionally known as energy intensity. The inverse of the energy efficiency in transport is the energy consumption in transport.
