One of the best cars to buy on the market today. The RS4, all wheel drive and 420hp

Make a all wheel drive car, with looks and sex appeal, 420 hp and a 8250 redline, one of the best built v8's engines on the market and you have the RS4. Tipping the scales at just under 4,000 pounds, the new RS4 is no bantamweight, but 90 percent of its torque starts at only 2200 rpm.

The RS4 disguises its weight and defies physics like an Airbus A380 in a Weight Watchers-meets-Houdini act that has much to do with the steering. It’s quite a bit quicker than that of the plain-Jane S4 but remains extremely speed variable. It’s odd to have effortless steering when parking but a tight, heavy rack at speed. It feels a tad fabricated, but hey, it certainly works. Most of the Audi’s tremendous ground covering ability is a result of, as usual, mechanical innovation, coupled with a little dose of expensive electronic trickery.

Take the suspension, for example, in which the dampers of each corner are diagonally connected. Because they share the same reservoir, the rear of the car is able to predict what’s coming next based on the displacement of fluid from the front. The system is fully mechanical and all but eliminates pitch and roll. It’s essentially identical to the Kinetic systems that have been outlawed in WRC competition due to their effectiveness.

The suspension is just one example of how a car that dangles most of its massive V8 ahead of the front axle line manages to throw its weight around like a rear-wheel driver — the revised, rear-biased (40F/60R) TORSEN Quattro system is the other big mechanical reason. The rear bias seems to be exactly what the doctor ordered to cure terminal understeer.

As great as the DSG is, it doesn’t make an appearance in the six-speed RS4, which should make stick-shift lovers happy. The only electronic interference with a damn good time, the ESP, has a two-stage defeat; stage one kills the traction control only, and stage two kills the stability control as well.

There’s a reason these things weigh so much. Like all new Audi's, the RS4 is downright lavish inside. With the “S” button off, it’s reasonably quiet too. Because of American crash regulations, we don’t get the cool, alloy-trimmed D-shaped steering wheel or the Konig bucket seats. (some excerpts are copied from sport compact car web).

From personal experience, I drive a 2006 S4 the model below the RS4, and I can vouch that the fit and finish of these vehicles are top notch. For the 2008 year, the price will come down considerably for the RS4 and that will finally make it one of the most sought after vehicles for the new year.
