#ur-quattro

In the 80s, Audi was the king of rallying, and it was all because of Quattro. Every Audi available today owes its life to the Ur-Quattro and the Quattro Sport.

So, you call yourself a car guy. Fair enough, you’ve browsed on over to AutoGuide so you must have at least a little petroleum in your veins. But are you a true automobile enthusiast? Do you know your accelerator pump from your synchronizer? Here are 10 vehicles every car guy needs to know about.

After its debut at the Geneva Auto Swow last week, Audi has released several videos of the new RS5, including some track footage alongside the original Quattro – the car that started it all. Taking after the Quattro, the RS5 is a mean machine with sexy styling. It is powered by the same 4.2-liter V8 found in the RS4 or R8, but output has been upped to a total of 450-hp at 8250 rpm, while maximum torque of 317 ft-lbs is available from 4000 to 6000 rpm. Combined with Audi’s S-tronic dual-clutch 7-speed transmission, quattro all-wheel drive and a 3,803 lb curb weight the RS5 can accelerate to 62 mph in 4.6 seconds.

Featured for the first time on the RS5 is Audi’s new crown-gear differential, which allows for up to 70 percent of the power to be distributed to the front wheels, or as much as 85 percent to the rear wheels. Under normal operation, the RS5 has a 40:60 rear-bias. In addition, the RS5 features an electronic limited slip differential, that slows the inside wheel in a turn when wheel spin is detected. Plus, an optional sport differential will be made available, distributing power between the rear wheels.

The RS5 sits 0.79 inches lower than the A5 and comes standard with 19-inch wheels (20s are optional). Other highlights include 14.37-inch, 8-piston front brakes, as well as optional carbon-fiber brake discs. There’s also Audi’s drive-select program to control different levels of throttle response, steering, transmission gear changes, the sport differential and even the exhaust system. As for the big rear spoiler, it pops up at speeds above 74 mph and automatically retracts at 50 mph.
