The TTS, to be unveiled at the North American International Auto Show in Detroit next week, tweaks the 2.0-liter four cylinder turbocharged powertrain to produce 272 hp and 258 lb-ft of torque. Peak torque is available between sweet places of 2500 and 5000 rpm on the dial. In other words, it should provide the right kind of giddyap for charging onto freeway onramps and cutting through serpentine backroad twisties.
To handle the extra boost pressure, Audi reconfigured the engine block, cylinder head, pistons, connecting roads and turbocharger. The TTS now flies from 0 to 62 mph in 5.4 seconds for the coupe and 5.6 seconds for the roadster, which puts it on a par with the Honda and the Porsche.
