This,is not your ordinary car. Not even close. Why,you ask? Well, for starters,the Mazda RX-7 does not use a reciprocating piston engine.Yes,that's right,no pistons,no cylinders,no camshafts,none of that.In it's place,is a Rotary engine,developed by Dr. Felix Wankel. The Rotary engine in itself is a masterpeice. The concept is this:instead of piston's moving up and down rotating a crankshaft, combustion spins a rotor ,connected to a crankshaft,in turn,turning the crankshaft. There are spots for injectors and valves inside the area where the rotor is. The particular Rotary engine in an RX-7 is a two rotor,twin turbo engine,generating 250 horsepower
Due to the extremely small nature of the rotary engine,the RX-7 is very light and very agile.Being small,the engine is able to be pushed back farther in the car,to better distribute weight. The RX-7 competes not only on the track but on the dragstrip,turning in low 13 second quarter miles stock. Turn up the boost a few psi and you are running 12's.
