The BMW all-wheel drive or 4X4 system, called X-Drive, ensures that the vehicle has the best traction all the time, improves agility and keeps you safely on lane.
When parking, the system reacts to the need for high manoeuvrability at low speed, by opening the clutch completely so the powertrain functions optimally. Acting virtually instantaneously and in a manner as to go virtually unnoticed by the vehicle's driver. X-Drive can direct up to 100% of drive forces to one axle and allow the driver to start up quickly, even on slippery surfaces or steep hills. X-Drive directs all power to the axles with the greatest wheel traction.
X-Drive is the all time, all-wheel drive or 4X4 system from BMW. Under normal circumstances, it distributes driver power between the front and rear axles in a nominal 45-55 ratio, and changes this figure depending on when the road surface or overall driving conditions change. X-Drive allows power to be split between the front and rear axles through use of a multiplate clutch located between the gearbox and the drive shaft. This setup allows X-Drive vehicles to split power in virtually any way it pleases. Torque can be transferred to the front wheels via electronically controlled multi plate clutch that is located in the transfer case. X-Drive does not have a center differential. Most of the time, the clutch is partially locked and power is transferred to both axles in proportion 45-55 front to rear. The power distribution can be altered to continuously variable levels from 50-50 to 0-100.

Just messing around with my goPRO and computer, certainly not great and doesn't really relate to our outdoor videos but it's whatever.

B5 Audi S4 quattro VAST Stage 3 FrankenTurbo Borla 0-60 mph AWD Launch Control & Drift...
A video compilation demonstrating the 2-step "launch control" feature of my custom VAST performance Stage 3 Frankenturbo tune. When the vehicle is stopped, the rev limit is set at 4,400 RPM for consistent launching. While holding this RPM, the turbos can produce up to about 6 psi with no load.
With this setup, 0-60 mph times in the high 3's are obtainable with a quick 1-2 shift.
The S4 also has piggie downpipes and a Borla single 3 inch Exhaust system.
Some bonus footage of a coworker who had never ridden in a semi-fast car before is also included. :-)
*edit* Unfortunately the girl in this video has passed away of Cystic Fibrosis (4/20/2013). RIP. She was a wonderful girl and will be missed by many.
Enjoy!

B7 Audi S4 in the snow
Playing with my GoPro cam after a 12" snow fall in Denver. Driving my B7 Audi S4 with Grislaved Nordfrost 5 snow tires. LOTS of traction! It's hard to see how deep the snow is from the camera view - you can see it come over the hood of the car, and in through the windows is some spots.
Audi S4 quattro EDL / ESP / ASR / Traction Control / AWD function in Deep Snow...
A short video showing how the EDL / ESP / ASR / Traction Control / and quattro TORSEN AWD systems work together to shift torque and gain traction in deep snow. You can clearly see how power is divided between all 4 wheels and constantly shifted to the wheel with the most grip.
How quattro works. quattro grip!
