 Please, do not test-drive a Sonata Turbo unless you're you're ready to buy, because you're gonna be compelled to buy it. The engineers of the 2.0 turbo Sonata are geniuses. The GDI was already cutting-edge for the regular 2.4 4-cyl, but the performance and fuel efficiency of the 274hp turbo are just pure genius. Simply put, it's a rocket. I effortlessly pass pretty much any car I want, anywhere, at any time, yet I get consistent 30-35mpg on the highway WITHOUT the ECO on and enthusiastic driving. Even the 'softer' limited suspension handles tight corners with great agility (18" low-profile tires help too). Beautiful engineering. And oh yeah, did I mention it's beautiful to stare at as well?
