    About Audi. Audi is the most popular brand among used cars. The annual output is 2 million vehicles.

    Oct 13, The BMW is the slower of the two, yet it still turns in a mph time of . So the Audi S4 finished well ahead of the BMW i this.

    But in the case of the new S4, it stands for an Eaton Roots-type supercharger replete with two four-vane rotary pistons and maximum boost of The revelation was how similarly the S4 handled. Select a Model 3. The most surprising discovery we made after repeatedly swapping back and forth between these two cars is how little the drive wheels mattered.

    Its reconfigured powertrain moves the engine rearward for better chassis balance. The all-wheel-drive system now sends a majority of the thrust to the rear wheels and also can actively apportion torque across the rear axle. The new, supercharged V-6 is lighter and more economical than the previous V The rather milquetoast A4 V-6 is gone, so while the A4 2. Both cars are bristling with everyday, usable power, and our testing had the Audi and the BMW neck-and-neck from 0 to 60 mph 5.

    In this instance, there really was none. The new S4 now offers a seven-speed S tronic dual-clutch automatic, while BMW continues with its six-speed automatic. But we wanted traditional six-speed stick shifts for our test cars to provide the purest sport-sedan driving experience.

    The most surprising discovery we made after repeatedly swapping back and forth between these two cars is how little the drive wheels mattered. Audis, meanwhile, were nose-heavy, and their all-wheel drive, while great for taming slippery tarmac, did nothing to mitigate their terminal understeer.

    For the i, that conventional wisdom pretty much still holds. But ever-wider tires, in staggered sizes no less, mean that the days of gently power-oversteering your 3-series through the esses are mostly just a memory. The revelation was how similarly the S4 handled. We hammered down lumpy, narrow New York two-lanes with quick curves, sudden dips, and sharp crests.

    Through it all, the Audi reacted just as quickly, and it carved corners every bit as enthusiastically, as the i. We could even feel the push from the rear as we powered out of tight turns. Nor were we terribly sad to skip the Drive Select package, which, along with the torque-vectoring axle, includes adjustable damping, dynamic steering with selectable effort, and a choice of throttle mapping. In fact, during our hardest driving over the worst roads, the S4 with its standard suspension configuration — which is firmer than that of the A4 — displayed even better body control than the already exemplary i.

    The S4, like the i, was adept at absorbing impacts without transmitting any harshness. Again, both cars impressed us tremendously with their ability to blend agility and a relatively comfortable ride. As it happened, both were riding on eighteen-inch wheels. On the i, eighteen-inch wheels are an upgrade over the base seventeens. In contrast, BMW is brave enough to let the 3-series live with relatively high steering efforts at low speeds, and the reward for its consistency is that the steering feels absolutely natural and never contrived, with great feedback as well.

    The sport package includes upgraded bucket seats, which are firm and comfortable. The driving position is above reproach, but the rear seat is still a bit tight for a six-footer. High-back sport seats are standard. Whereas the i has little to visually separate it from the base i, the S4 is far less likely to be confused for a run-of-the-mill A4. The S4 brandishes marks of distinction that include its eighteen-inch wheels, a lower ride height, a unique grille, aluminum mirror caps, and a rear diffuser.

    These two cars are standouts in their ability to blend size and comfort, power and efficiency, fun and practicality. Maybe our findings would have been different on a racetrack, but on the most challenging public roads we could find, Audi scored a remarkable achievement with the S4, as its engineers have finally been able to get their all-wheel-drive sedan to handle as well as the benchmark BMW.
