Rob Dahm, notorious rotary-powered car builder, has firmly jumped into the deep end of the pool with his latest project: The world's only 15.7-liter, tri-turbo Y12 rotary engine. If that doesn't make any sense, you're not alone.

He's an eccentric motorcycle and engine building genius who regularly creates mind-bending engineering alchemy and has millions of fans... So why is his extraordinary work so badly undervalued at auction? Someone's getting a bargain today.

Despite its reputation as the world's largest engine manufacturer, Honda existed more than 70 years without building a commercial V8. That all changed a year ago, and now Honda is growing its lineup of advanced, high-powered 5.0-liter V8 VTEC motors.

One of the rotary engine's biggest champions, AIE has been advancing rotary design since 2012. Its latest release shows that Wankel engines can be a perfect fit for compact, power-demanding applications in robotics and aerospace.

The Alpine Alpenglow is back, this time equipped with an all-new "Hy6" twin-turbo V6 engine developed from the ground up to run on hydrogen. The Hy6 doubles the power of the last Alpenglow, delivering true supercar performance and rumble.

LiquidPiston is testing a 10-kW generator it's prototyped for the US military, which it claims is just a quarter of the size and weight of the Army's current genset. That's thanks to its innovative rotary engine that delivers extraordinary power density.

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has filed a patent to make a 6-stroke engine.

This fire-breathing 27-liter 1,800-horsepower Rolls-Royce Merlin aero engine famously powered the Spitfire, Hurricane, Mustang, Lancaster and Mosquito WW2 aircraft. It's been mounted on a trailer and really is a sight to behold and feel.
