Yes it is, got to see one up close the other day. The more I read about battery technologies, the more it looks like the energy density increases are not in lock step with "Moores Law" i.e. chip speed and capabilities doubling every 18 months.
With that said, as a fan of the Wankel Engine ( yes I know their are bazillion detractors and comments ) I'd love to see something like this powered by a Rotary on CNG, especially if that is a range extender to an electric drivetrain.
As I type this, their is a gent in California getting a 3 Rotor Mazda ready to go to the dyno that is connected to a "Turbo-Compound" unit. This TC recovery device captures the waste energy of the exhaust and sends it back into the main shaft if you will. This unit might reduce the specific fuel consumption enough to make the Rotary viable again.... Stay Tuned...
Ohhh...NSU RO 80 wankel engine...good old times...:-(
Wankel engine is nice.. Until you try to race someone going uphill. LOL They lack compression, unless they’ve fixed that but I think it’s inherent weakness in rotary design.
Turbo a Wankel? But how do you get compression out of rotary? Tough proposition, no?
