I was thinking, because a rotary engine is much smaller than a piston engine of the same power to me this would make an ideal candidate for a small car such as the MCC smart. The only drawback I can see is the fuel consumption being quite low which is not really ideal for a city car.

So what do ya think?:)

it's true... if Mazda refined a design specifically for low fuel consuption, they would end up with an extremely small engine which would produce adiquate torque and power for a little urban gokart...

Mazda should make a new coupe based on the Mazda3 with rotary engine!

Do you think Mazda could develop a single rotor Renesis for just such an application? That could have significant impact on the micro car market.

They can......remember the RX-2, RX-3 and RX-4 from the seventees?

All those cars had twin rotor engines... the 10A, 12A, and 13B.

However, Mazda did in the past develop a single rotor engine though it never was put in production. There are some companies out there that will build you a single rotor Mazda engine (Atkins Rotary comes to mind), I've been told they're a lot of fun in old VW Bugs. :D

Yeah, you're right. My mistake

But why a one rotor engine? Two will work just fine :D And it is allready very tiny, so it will probably fit in any Mazda

The answer is cost. The first gen rx-7s (approx 2350 lbs) with a 12a had epa fuel economy ratings of 21/30 mpg. :eek:

A 1.0 or 1.2 liter renesis would be good for a smaller car but the new piston engines that Mazda developed would still have better emissions and probably better fuel economy while costing less.
