I had this question for my homework. The answer is 30-35%
Most of the energy is lost as heat.
~25%

very ineffecient unless maintained to factory specs. witch most are not.
depends on the car but your typical car will weigh any where from 1000-2300LBS and like i said it depends on the car. A typical V-8 engine complete with exhaust manifolds weighs less than 600 pounds.
There is not a typical Ford engine size, as the Ford car company creates many different cars with different engine sizes. The Ford Ka, a small city car, has engine power of 59 BHP and 5000 RPM.
most cars aren't ENERGY efficiant but some are GAS efficiant.
People often think of compact cars when they consider fuel efficient cars. But there are many midsize cars and SUVs that are fuel efficient. In choosing a car that will have good gas mileage, also consider the size of the engine and the vehicle size. An engine that is too small for the size of the vehicle may save you on fuel but cost more on engine repair or replacement.
A streamlined car would be more efficient than the same car without streamlining as it would present less drag. Unfortunately, streamlining by itself does not make a car efficient. Efficiency is the product of may different things such as the type of and inflation of the tires, the size and efficiency of the engine and etc.
When it comes to fuel efficient and luxury cars the best bet is to compare hybrid-engine designs. More and more luxury car companies are now coming out with fuel efficient hybrid-engine designs.
The main component that makes hybrid cars efficient and is their engine. Hybrids have a gasoline powered engine, but when this engine is coupled with an electric motor the overall effect reduces emissions, requires less fuel, and gets a lot more mileage than a standard gasoline powered car or a purely electric car. A hybrid car's engine and transmission charge the electric batteries that are also part of the car.
yes at 36 mpg it is a very efficient car
