A normal Wankel has a triangle rotor spinning in a peanut-shaped housing. Liquid Piston flips that; now the peanut rotor spins inside a triangle housing. That small change makes a big difference. The ...

This file type includes high resolution graphics and schematics when applicable. Automotive engineers are concerned with weight-to-power ratios when designing vehicles. While light-weighting is a ...

Most Japanese performance car enthusiasts are familiar with the 13B twin-rotor engine Mazda equipped the RX-7 and RX-8 with. But unless you've owned and modified an RX of some type, chances are you ...

Lots of displacement, more compression, and a ton of valve lift used to be the recipe for a typical professional-level drag-race motor. Today, this same description could just as easily be a serious ...
