Rotary Engine coming to Audi
Submitted by Berny Herrera on Thursday, April 22, 2010 - 10:41pm


Audi is looking at the rotary engine, fitting a Wankel powerplant to the A1 e-tron concept shown in Geneva in March. The one-disc rotary engine was co-developed with Austrian engineering house AVL. Car&Driver experienced its operation, and it’s smooth and quiet and avoids the shuddering on restart of a piston engine. Who wants to be disturbed as they’re humming and singing and smiling while depleting their electric-vehicle’s batteries? Not the Car&Driver folks. It’s certainly nice, but C&D next question was whether we could see a powerful rotary-engined Audi without all the electric-motor wizardry. Not a chance, says Ingolstadt. Pity.

Here, a tiny, 0.25-liter Wankel rotary gas engine—mounted in the rear of the car will hum at a constant 5000 rpm to generate electricity and recharge the batteries, extending the car’s range by another 124 miles per tank. A regenerative braking system can also feed energy back into the system, while the range extender can be switched on and off at will by the driver.

Rotary coming back to Audi......sort of

Rotary engines are in Audi's history. I believe that Audi grew out of NSU. Back in the 60's NSU introduced the worlds first production rotary car, the Wankel Spider, and later the RO80 but when the company failed it's facilities, etc ended up becoming part of Audi.

I can't wait to see if Audi produces a rotary car!

Mazda may want to look at this electric / rotary union and use it to develope the new RX-7. Torque has always been and issue for rotaries. Torque is not an issue for electric engines. So electric assisted acceleration could end any torque problems in the future of rotary cars. Of course the rotary would charge the batteries. Think about it, sounds like a winner to me.

It'll be hard to win it if you don't spin it!!!!!!!!!!!!!!!

Wow, Audi is really first class if they do this. After seeing the Mitsubishi Eclipse & Fisker Karma prototypes in 2008, It really got me thinking what a great idea it would be to add a wankel to a hybrid equation. It is really hard to beat the power to weight ratio of a rotary. Those are key factors in todays light weight fuel efficient cars. I really thought that it would be a joint venture with Mazda and Fisker to do this.

Audi sees the light!

While there are alot of skeptics who won't see any benefit or purpose for the rotary. It was brilliant for Audi to use it as a battery charger or range extender.

Correct me if I'm wrong, Dan (or anyone).
I've read that in the past, Wankle developed tiny rotaries that ran the a/c system in Big Riggs (instead of their deisel engine) while the driver slept. That said. The concept of a rotary piggy-back to assist other systems has been used before. And we're still finding new ways to put it to use.

Healthy competion between manufacturers will speed the evolution of the rotary, like the Chevy small block changed the game in the mid to early 1900's.

Let the wars begin!
