Somebody posted a video of an old audi and it made me think of this.

Just an brief history of the group B class in the world rally in the 80s and some of the INSANE cars that were in it.

A very interesting and very brief period in racing history.

Group B

Here's some of the cars too. Notice the rally verison of the Delta S4..WOW. turbo supercharged. Lots of midengine fun.

Ah, the Lancia Delta Integrale. I like to think of it as the beginning recipe for the Lancer and DSM. AWD, with a mid-length wheelbase and a turbocharged engine. Definitely way ahead of it's time.

Thats some pretty cool history. I didn't realize the depth the cars were before...

Definitely some very technologically advanced cars for the time.

"Therefore Lancia spent a lot money with Abarth to develop a system combining both turbocharger and supercharger to get a perfect output. It employed twin intercoolers, one for the turbo and one for the supercharger. The supercharger worked at low speed. Once the turbo cut in, a bypass valve relieved the pressure from the supercharger so that energy efficiency was be lifted."

Ofcourse it's a bit more complicated than that but you get the idea.

"As a result, the 1.8-litre engine had an outstanding power of 250 hp and a healthy 214 lbft of torque, while the rally car had at least 470 hp and 333 lbft"

It seems like we're entering another era of big horsepower turbocharged awd cars which is cool.

The Audi was a monster as well. It had 600hp. It looks like nothing out there.
