One of the greatest, if not the best roadster to ever come out of Japan is the focus of a few rumors. The next-generation Mazda MX-5->ke1185 could weigh around 2,200 pounds and be able to manage 50 miles per gallon without losing any horsepower. While most people already know about these numbers and the new SKY-G engine, Best Car Japan is reporting that the SKY-G may not be getting the job.

The Japanese magazine reports that the 2010 Mazda->ke53 Miata will be getting the old fashioned rotary engine. The 1.2-liter or 1.3-liter will also help keep the cars weight down. What makes us question this rumor is the rotary engine's past. These motors have been less than fuel-efficient over the years so it seems a bit strange that it would be able to get 50 mpg.

We think that the new rotary will be paired with a hybrid, like we find in the Fiat 500 prototype by FEV. That car has a rotary motor that acts as a generator for a lithium-ion battery pack.

While all this talk is fun, we put all our chips in favor of a four-cylinder with a turbo. This will help keep the cars price down and the fun at an all time high.
