Get the rx7 mug.Also known as the Savanna in Japan, it has 3 generations.
1st gen - FB3s
2nd gen - FC3s
3rd gen - FD3s
The Rx7 was only one of the many cars that were powered by the rotary engine. Dr. Ing. Felix Heinrich Wankel invented this type of engine in the 1950's. This design was bought by Mazda and used in many of they're automobiles from the 1960's - today.
12A (1.2 liter twin rotor n/a) 13B (1.3 liter twin rotor n/a / turbo) and 20B (2.0 triple rotor n/a / turbo) are some of the rotary engine codes that are well known. The engine sits just behind the Rx7’s strut towers making it a true front mid engine car which gives the car great handling characteristics and the proud owner bragging rights. The turbocharged rotaries are terribly unreliable and in reality have to be overhauled every 70,000 miles. The apex seals are one of the weakest points in the motor, second warping the rotor housing from over heating occurs very often. These cars have terrible gas mileage and are not pleasant to drive behind with your windows down. A rotary engine burns oil from the factory to lubricate the rotor housing walls. Failure to pamper these cars will result in a blown engine very early in the cars life. These cars have a very hard time passing smog tests with high milage.
Rx7’s are great cars from beginning to end, I love them, but I already have a girlfriend that needs enough maintenance.. my 240Z does me just fine.

Tech stuff:
A four-stroke engine's cylinder fires only once every two revolutions.
A two-stroke's cylinder fires every revolution, so a 2-stroke has (all things being equal) double the output for the same cylinder size.
Problem is that 2-stroke petrol engines don't scale up in size well (though some industrial Diesels *are* 2-stroke).
The rotary fires (like the 2-stroke) once for each revolution, so it has potentially twice the output for the same volume as a 4-stroke, plus the rotary *does* scale up OK.
Piston engines absorb energy during the compression cycle, giving a negative torque, but rotaries provide positive torque for each entire revolution, since compression, power and exhaust occur simultaneously.
Rotaries can run to very high rpms compared to piston engines because their motion is continuous rather than reciprocating and because the few rotating parts are small-ish and can be made very robust, while piston engines are limited to lower and lower rpms as they scale up.
Rotaries are thirsty if you cane them, but I get 30 mpg touring at 70 mph in my 1985 Series 3, no mods.
Fuel consumption is an issue - it's to do with the combustion space being a long, thin rectangle, rather than the more ideal cylindrical space of a piston engine.
And having a turbo giving over 270 shaft HP from a 1.3 litre engine has got to be a temptation....
But no, NOTHING else in the car park looks as damn sexy!

Get the rx7 mug.The best damn car out there with its light wait rotary engine, not only is it good, but damn does it looks "Freakin Sweet!"
Bob: "Hey look at that sweet Honda Civic"
George: "Fuck that slow peice of shit, look at that RX7!!!! it will smoke that stupid rice rocket."

Get the rx7 mug.Stand for Rotary project 7. The engine uses no pistons. It has less parts than a piston engine, which means less friction. Rotarys are unique to the piston, and are a whole nother ball game to fix. It came in in 2 popular engine names the 13B which was on the FC 1986-1991 (or in japan 1992) the 13B-RE which is in the FD 1993. The FD was asequential turbo setup, the FC was a single turbo(in the states they were NA or Turbo)(1992 Japan was produced with special FC's the Infini models) both cars offer near 50/50 weight distribution. they are light and potently fast. Those Mustang guys think 1.3 liters is nothing huh? Well, you be suprised how the FC's and FD's can certianly become a challenge for the 5.0 crap. (BTW, all the FC's in Japan were turbo even the convertibles.) The Us did not get as lucky.

Get the Mazda RX7 mug.The finest automobile ever produced. It has a wenkel 13B twin-rotor engine that will match the power out put of any V-8. With the addition of the twin turbo option and a few minor engine mods(cold air induction and other simple up grades), the RX7 is virtually unbeatable.
Mustang/Camaro owner: "Wow, that RX7 has some really nice tail lights!"
Dickhole in a Honda: " Really? I only got to see them for a few seconds before he was too far ahead of me to tell!"
