As engine output has exploded, with super-sedans from Europe roaming about with previously unthinkable horsepower numbers, the 2010 Audi S4 makes more out of less. Two less cylinders, seven less horsepower, and 1.2 liters less displacement than its predecessor, to be exact. The magic of the S4 is that Audi’s skilled engineers have not only conjured up a lot more torque and significantly better fuel economy, they’ve made the new S4 quicker than the last one. Combine all this with a quattro all-wheel drive system that borrows refinements like torque-vectoring from the manic RS4, and the S4 proves that it’s not just some dry statistics that have been tweaked; the sedan’s agility is seriously improved. The positives aren’t just limited to the drivetrain, as the S4 wears a spiffy new set of duds, with aggressive split-spoke alloy wheels, a more aggressive front fascia, and trunklid spoiler to distinguish it from lesser Audis.
