Although the Audi A5 Sportback didn't yet make its live debut, the S-Line version is already here, to spice it up against the performance-oriented competitors. This 2010 S5 Sportback will make its debut at Frankfurt Motor Show, with sales starting in spring 2010, coupled with a price-tag of 57,900 euros ($82,761 USD). Audi do it best with their S-Line models, as they promise to pack a lot of performance, with only settle changes compared to its less-powerful siblings.
Concerning the powertrain, the Audi S5 Sportback similarly underscores its superiority: a 7-speed S-Tronic dual-clutch transmission and Quattro permanent all-wheel drive are standard equipment. Upon request, Audi will also include a sport differential, that variably distributes power on the rear axle between the rear wheels. Power comes from Audi's latest 3.0L supercharged TFSI V6, now packing 333 hp and 325 lb-ft of torque. Although it's actually heavier than either the S5 Coupe or S5 Cabriolet, this S5 Sportback still sprints to 60 mph in 5.4 seconds, and reaches a limited 155 mph top speed. Plus, this engine will manage 25 mpg fuel-economy, claiming the S5 Sportback as "the best in this power-output category."
So how does the S5 Sportback differs from the standard A5 Sportback? Well, first look for the 4 exhaust pipes outback, then extended body-kit, and then of course the classic Audi S-Line trademark cues, like the 18-inch wheels, and S-Line grill, with S5 badges. Inside, sport-bucket seats with two-tone color leather are added, coupled with S5 badgeds around the cabin.
