Oct. 9, 2012 - PRLog -- The upcoming debut of the all-new 2014 Impala will mark a breakthrough in modern engine technology, featuring Chevy's Intake Valve Lift Control (IVLC) for the first time in a gasoline-powered engine. The advanced technology will help the Impala stay at the front of the pack when it comes to fuel economy, providing one of the best EPA marks among the full-sized sedans in its class.

The 2.4-liter Ecotec I4 engine works by making automatic adjustments on the fly, controlling air intake more efficiently. When the car is driven normally, it needs less air to operate, so the engine limits intake flow with its low-lift cam profile. If the driver needs to accelerate aggressively, or if the engine is worked under a heavy load, then the high-lift setup automatically makes the necessary adjustments; the appropriate mixture of air and fuel is delivered to the engine and it responds with more power. With IVLC technology, the end result is a more efficient engine that helps maximize fuel economy so drivers can save money at the gas pumps.

Drivers will still have their options, though, with two other engines to choose from, including a 2.5-liter Ecotec I4 with GM's e-Assist, which allows for 182 horsepower and 35 miles per gallon on the highway. The third choice, a powerful 3.6-liter direct-injection V6, boasts an impressive 303 horsepower. All three will feature a responsive driving experience, with six-speed automatic transmission and a four-link suspension system in the back. EPA ratings are still pending as Chevy fine-tunes the lineup, but the all-new 2014 Impala is set to make significant improvements over previous models when it debuts early next year.

Mark Reuss, president of GM North America, had this to say about the improvements: “The 2014 Impala re-establishes this iconic Chevrolet nameplate as a design leader, with bold styling that will turn heads for years to come. The team has also delivered the comfort, safety, fuel efficiency and technology that will strengthen Impala’s leadership in the highly competitive full-size sedan market.”
