Inside Line has learned that Hyundai plans to offer a direct-injected version of its 2.4-liter four-cylinder engine in the U.S.-spec 2011 Hyundai Sonata. The engine, we're told by sources inside Hyundai, will be rated at 195 horsepower — a significant bump over the 175-hp rating for the 2.4-liter in the current Sonata and more than Honda offers in the four-cylinder Accord EX.

In a nod to both fuel economy and performance, sources tell us there will also be an optional turbocharged engine, most likely the D.I. 2.4-liter with power in the neighborhood of 240-250 hp. This will make the Sonata one of only four turbocharged sedans in the midsize market along with the Subaru Legacy, VW Passat and VW CC.  

It will also make the 2011 Sonata Hyundai's second turbocharged model behind the rear wheel drive Genesis Coupe 2.0T, which uses a boosted 2.0-liter four-cylinder rated at 210 hp.
