1.6
The G4GR (also called the 1.6 D) is a 1.6 L (1599 cc) DOHC engine. Output is 116 hp (85 kW) at 6000 RPM and 106 ft.lbf (143 Nm) at 4900 RPM. The engine's bore is 77.4 mm and its stroke is 85 mm. A double overhead cam (also called a dual overhead cam, DOHC, or twincam) engine is a type of internal combustion engine where the camshafts that operate the intake and exhaust valves are mounted above the cylinders, and where there are separate camshafts for inlet and exhaust valves. ...
1.8 There are two different 1.8 L engines, the G4CM and G4CN. The G4CM (also called the 1.8 S) is the SOHC version. It displaces 1796 cc from a bore of 80.6 mm and a stroke of 88 mm. Output is 97 hp (72 kW) at 5500 RPM and 104 ft.lbf (141 Nm) at 4500 RPM. Single overhead cam (also SOHC) refers to the internal combustion engine design where one camshaft is located above the valves. ...
The G4CN (also called the 1.8 D) is the other 1.8 L , a DOHC unit displacing 1836 cc with an 81.5 mm bore. Output is 125 hp (93 kW) at 6000 RPM and 116 ft.lbf (157 Nm) at 4500 RPM. A double overhead cam (also called a dual overhead cam, DOHC, or twincam) engine is a type of internal combustion engine where the camshafts that operate the intake and exhaust valves are mounted above the cylinders, and where there are separate camshafts for inlet and exhaust valves. ...
2.0 The G4GF (also called the 2.0 D) The engine is available in SOHC (2.0 S) and DOHC (2.0 D) versions. Bore remains the same on both at 85 mm with stroke shared with the 1.8 at 88 mm. SOHC power is 102 hp (76 kW) at 5000 RPM and torque is 117 ft.lbf (159 Nm) at 4000 RPM. The dual-cam version produces 133 hp (99 kW) at 6000 RPM and 134 ft.lbf (181 Nm) at 4500 RPM.
Beta II During 2001-2002, the new Beta II engine made its debut in models such as the XD Elantra and GK Tiburon. Output is 138 hp (102 kW) at 6000 RPM with 136 foot pounds of torque (184 N·m) at 4500 RPM. It has a cast iron engine block and aluminum DOHC cylinder heads. The latest version of the 2.0L Beta engine (G4GC) features CVVT, which only in intake side, a first for Hyundai/Kia. The following changes were noted. A double overhead cam (also called a dual overhead cam, DOHC, or twincam) engine is a type of internal combustion engine where the camshafts that operate the intake and exhaust valves are mounted above the cylinders, and where there are separate camshafts for inlet and exhaust valves. ...
Continuous variable valve timing (CVVT) is an automotive technology that allows the intake and/or exhaust valve timing to be varied during engine operation, except there are no discrete stages for affected components. ...
