 When it comes to vehicles, many individuals are all about power and speed.  How many horsepower ?  What kind of torque ?  But do people even understand what it is they are talking about ?

 By definition, an automobile’s turbo (or turbocharger) is “a turbine driven forced induction device that makes an engine more efficient and produce more power for its size by forcing extra air into the combustion chamber.”  The turbine forces more air and fuel into the combustion chamber, thereby making a turbo engine more powerful and efficient than a naturally-aspirated engine.  Turbo engines rely on the build up of exhaust gas pressure to drive the compressor and have been around since the 1920’s when they were introduced in aircraft engines. 

 Many individuals refer to turbo engines as superchargers but they are actually different.  Whereas a turbo engine gets it power from the turbine that uses a vehicle’s exhaust gas, a supercharged engine is driven by the engine, often by a belt that is connected to the crankshaft.  Turbochargers may be a little slower to respond than a supercharged engine, but the positive tradeoff is its efficiency.   - Wikipedia

 Volkswagen and Audi manufacture several turbo vehicles including the Beetle, Passat, Jetta, TT, A4, and the TDI lineup (turbocharged direct injection).
