High-Tech Engine to Boost the 2014 Chevy Impala's EPA Rating
The 2014 Chevrolet Impala, set to debut early next year, will offer a significant improvement to fuel efficiency over previous models with its state-of-the-art Intake Valve Lift Control system (IVLC).
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;
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:
