Wankel's great design, extremely smooth! Gas-guzzler though! And loud!
Mazda just patented a 2-stroke turbo engine design... Should make for very good power-to-weight ratios. Modern EFI allows for optimum injection-timing into ports for power
and emissions. Although Toyota patented one 20-years go with supercharger for scavenging, never came to market though.
KTM actually has some EFI 2-strokes on market already... Wish we got those here!
