Hyundai's new lineup introduces a turbocharged variant to its all four cylinder lineup in the new Sonata. The same engine that powered the 2008 Kia Koup concept that produced 290 hp now lives in the Sonata Turbo variant. Its been tuned to 274 hp and 269 pound feet torque.
Hyundai is using a twin-scroll turbocharger, like the ones that are used by BMW in its latest engines in the 2011 version of the 535i. The exhaust flow from the pairs of cylinders fed into the turbine by separate paths to ensure optimum response.
The turbo engine is offered with a six-speed automatic transmission with paddle shifters on the steering wheel. The fuel consumption is pretty healthy too, with them estimating 22 mpg city and 34 mpg on the highway. More below.
