Mazda RX7 boasts to be the only one using a rotary type engine. And for that matter, owners of this reputable race car from Mazda could boast of them as well. RX7 is equipped with a twin rotor Wankel rotary engine, which was invented by German Felix Wankel. This revolutionary engine is said to be only equipped in helicopters. But thanks to the geniuses of Mazda, RX7 now holds in its body the power that a rotary engine has.

A truly-remarkable Mazda racer could be measured on how well he handles this unique engine as it is somewhat difficult to control. An advantage is that it is a much lighter engine compared to the regular piston designed engine. It doesn’t have connecting rods, conventional crankshaft, crankshaft balance weights and other things found in a regular engine.

And this, could only be found in Mazda RX series. Now you know, The Only One.
