The World Gasoline Engine is a family of straight-4 piston engines, based on the Global Engine Alliance design.

Three engines have been produced: a 1.8 L, a 2.0 L, and a 2.4 L. With 1.8 L variant being used on vehicles sold outside of the United States. The initial design of the engine block and cylinder head was handled by Hyundai as part of the Global Engine Alliance. The engines feature an aluminum engine block with siamesed cast iron cylinder liners (that is cylinder liners that don't allow coolant to flow between adjacent liners). By using cylinder liners the engine's bore can be altered, therefore the displacement as well, just by adding a different set of cylinder liners. The engine also features an aluminum cylinder head with double overhead camshafts and variable valve timing.

The 1.8 L I-4 is a dual overhead cam (DOHC) inline 4-cylinder gasoline engine capable of 148 hp (110 kW) and 125 lbf·ft (169 N·m) of torque. The engine has displacement of 109.7 in³ (1,798 cc) with a bore of 3.38 in (86 mm) and a stroke of 3.05 in (77 mm). The compression ratio is 10.5:1.

The 1.8 L DOHC inline 4-cylinder engine served as the standard engine in the Dodge Caliber SE and SXT trim for the 2007–2009 model years.

Applications:

The 2.0 L DOHC inline 4-cylinder gasoline engine capable of 158 hp (118 kW) and produces 141 lbf·ft (191 N·m) of torque. The engine has a displacement of 121.9 in³ (1,998 cc) with a bore of 3.38 in (86 mm) and a stroke of 3.38 in (86 mm). The compression ratio of the engine is 10.5:1. The 2.0 L engine is offered by Dodge in the Dodge Caliber. Outside North America, the 2.0 is the base engine for the 2007 Chrysler Sebring and 2008 Dodge Avenger.
