This car looks realy interesting for someone who wants an inconspicious DD that could be fun.
See the article here:

The impoartant stuff:
"The engine is required to sip nothing more exotic than 87 octane fuel. That is, the 2.0T generates its 274 horsepower at 6,000 rpm and 269 pound-feet of torque from 1,750-4,500 rpm on the cheap stuff."
Whats cool is the type of wastgate control they are using on this to get it to make power on low octane:
"One bit of turbo trickery deployed in the 2011 Hyundai Sonata 2.0T is a fully electronic wastegate actuator (conventional pneumatic actuators are so last week). It allows a greater degree of control over boost than traditional actuators, but Hyundai has also found other benefits. For instance, the electronics can open the turbocharger's wastegate during cold starts to enable rapid light-off of the catalytic converter. In turn, this functionality allows the catalyst itself to be positioned under the floor, far away from the turbo, where it induces less exhaust backpressure than would a close-coupled catalyst. And backpressure is the enemy of power and response, especially when you're trying to make a lot of power on low-octane fuel. The e-gate (we just made up the term) also permits some trick tuning during part-throttle conditions. By opening the drive-by-wire throttle and manipulating boost, part-load pumping losses are reduced, improving fuel economy."
