2010 Hyundai Sonata being evaluated on a Detroit area freeway

Hyundai's Montgomery, AL factory added production of four-cylinder engines last year, but recently the engine line has been getting some upgrades. Evidently, Hyundai is getting ready to add direct injection to its 2.4-liter four-cylinder engine. Like other DI engines, the revised version gets increased power along with lower fuel consumption. The DI four cylinder will debut in the refreshed 2010 Santa Fe this fall. Next year, when the completely redesigned Sonata goes into production, it will also get the DI engine.

Power from the DI four cylinder gets bumped from 176 to 200 hp, and it will likely get around 5-10% better gas mileage. The all-new Sonata will be unveiled at the LA Auto Show in November. Next year a hybrid model will join the lineup, as well.
