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.

DeepDrive is hard at work on a unique radial flux motor concept with two rotors. It's said to produce copious amounts of torque from light, compact, cost-efficient package. DeepDrive is now starting on-road testing with help from its neighbors: BMW.

After launching a modern pulsejet engine for UAVs back in March, Wave Engine Corporation announced this week that it's delivered the first units. The loud, pulse-combustion fire-breather is officially finding its way to air-bound vehicles.

One of the world's largest engines becomes a clean generator. Originally designed to burn diesel, dual-fuel, or gasoline for tankers and container ships, the Wärtsilä 31 marine engine gets a new life generating clean, renewable electricity.

An innovative new combustion engine eliminates half the guts of a traditional engine, and uses a fascinating internally rotating piston and sleeve arrangement, making it lighter, simpler and more efficient while still making strong power and torque.

Wave Engine Corp has aced a demonstration flight of a simple jet engine with no moving parts. A modern version of a pulsejet, the J-1 engine powered a UAV through take-off and several mid-air stop/starts before the aircraft nailed the landing.

Internal combustion engines have still got a few punches left in them. Case in point: Kiwi drifter "Mad Mike" Whiddett has unveiled "the wildest drift car I could think of," built around the world's first 5-rotor Wankel rotary engine.

According to the UN, there are about 258 million widows in the world. Tomasin Racing feels these are rookie numbers, so it's making a kit that turns a standard Honda CRF 450 into a certified widow production facility with a 500cc 2-stroke engine.
