Two Wankel engines

The “okay so how am I meant to deal with this?” situation. Named after the (gigglingly funny) rotary Subaru in Top Trumps that doesn't seem to be comparable in any meaningful way with the other engine categories

Dealer: (Triumphantly slapping down a Ferrari Testarossa) Power: FUEL INJECTED V12 SUCKER! BEAT THAT!

Second player: (Mysteriously) AHA!! ONE WANKEL ENGINE!
