The 2012 Accent’s all-aluminum 1.6-liter Gamma four-cylinder engine utilizes the latest engine technology to deliver a class-leading 138 horsepower and 123 lb-ft of torque and a best-in-class standard 30 mpg city and 40 mpg highway fuel economy rating.
The engine’s most notable feature is its use of GDI, a first for the subcompact category. By precisely controlling the injection of fuel, GDI allows for better fuel economy, increased power and reduced emissions. The application of Dual Continuously Variable Valve Timing (D-CVVT) on both intake and exhaust camshafts allows for increased efficiency, improved fuel economy and reduced emissions. Other elements resulting in reduced fuel consumption include an Alternator Management System, an offset crankshaft design, variable induction system and electronic throttle control. To reduce lifetime operation costs and increase reliability, the Gamma features a maintenance-free silent roller timing chain. The Gamma also uses innovative anti-friction coatings such as CrN Physical Vapor Deposition (PVD) coating and Diamond Like Carbon (DLC) coating.
Several other systems have been improved over the outgoing model, each contributing to increased fuel efficiency. The 2012 Accent can be equipped with a six-speed manual or automatic transaxle with SHIFTRONIC manual control, delivering smooth and efficient power delivery. Low-rolling resistance silica tires and a slippery shape (0.30 cd) reduce friction with the road and the air. This aerodynamic shape also includes a kicked up trunk edge, wheel arches which shield the tires and an optimized engine undercover. Finally, the ActiveECO function modifies engine and transmission control to smooth out throttle response. By turning on the ActiveECO function, drivers can realize up to a seven percent increase in real-world fuel economy.
