I’ve got a lot of respect for people who try to do things differently, especially when it comes to cars. We’ve been driving the same basic contraption for over a century now, from the engine to the suspension to even the accelerator. While I love cars, I also love the innovation and creativity I’m seeing from the alternative fuel movement from both big manufacturers and small, and some old ideas are getting a second look.

Take the rotary engine. It has fewer moving parts than a standard engine… but it also makes a lot less torque, requires precision machining, and devours oil rather quickly, making it rather useless for towing or performance. Plus, since the internal combustion engine has become so ingrained in our culture, many mechanics can’t make heads or tails of the Wankel, as it is called. But this little engine (made popular by Mazda in the 70’s and 80’s) could find a second life… as an electric vehicle range extender.
