Details: Hyundai's brand new 2.4-liter four-cylinder engine



Hyundai recently released the specs on their all-new power plant, which will be fitted into the 2011 Sonata model. Its a direct-injected four-cylinder that will make 201 horsepower in naturally aspirated form.

This is set to be the base engine for the new Sonata, while an available V6 is still a rumored option in higher trim levels.

Now some information for the true motorheads out there: this 2.4-liter inline engine will use a, 11.3:1 compression ratio and variable valve timing on both the intake and exhaust valves. It will also feature a three-stage intake system and pump out 184 lb-ft of torque.

Following the direct-injection trend, Hyundai has designed this engine to spray fuel directly into its combustion chambers (rather than previous engines that had fuel injectors mounted within their intake manifolds). It's all very technical, but the power gains, throttle response, and fuel efficiency of direct-injection has persuaded most automakers to completely redesign the fueling systems of newer engines.

 

Another great feature of direct-injected engines is their performance and efficiency when combined with turbocharged technology---something that Hyundai will be offering with this very engine. Expect a turbocharged Sonata in the near future with around 240 horsepower.
