Selected as one of Ward’s 10 Best Engines, the Accent’s all-aluminum 1.6-liter Gamma four-cylinder engine features the latest innovations in engine technology to deliver an unsurpassed 138 horsepower and 123 lb-ft of torque and a standard 28 mpg city and 37 mpg highway EPA fuel economy rating.
The engine’s most notable feature is its use of Gasoline Direct Injection (GDI), the first to introduce GDI technology to 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.
