Hyundai's Alpha automobile engine was the first to be designed in Korea. It was a modern SOHC 3-valve straight-4 and was available in turbo and naturally aspirated versions. The first Alpha engine was introduced in 1993 in the Hyundai Scoupe and were available through 2002. Alphas were initially produced in 1.3 L (1341 cc) and 1.5 L (1495 cc) versions, being replaced with 1.6 L (1599 cc) and 1.4 L (1399 cc) Alpha II versions introduced in 2003 and 2005. In 2011 the Alpha engine was replaced with the Hyundai Gamma engine.
1.3
The G4EH is a 1.3 L engine, with a bore and stroke of 71.5 mm and 83.5 mm, respectively. Output was 71 hp (53 kW) at 5500 rpm and 81 lb·ft (110 N·m) at 3000 rpm for the carbureted 1.3 CON version and 83 hp (62 kW) at 5500 rpm and 86 lb·ft (117 N·m) at 3000 rpm for the SOHC 1.3 S.
1.5
The G4EK is a 1.5 L engine, with a bore and stroke of 75.5 mm and 83.5 mm, respectively. The SOHC 12 valves 1.5 S generated a respectable but not notable 92 hp (69 kW) at 5500 rpm and 97 lb·ft (132 N·m) at 4000 rpm, although some websites quote the torque rating as being 97 lb·ft (132 N·m) at 2700 rpm. European version makes 90 hp (66 kW) at 5500 rpm and 129 (or 132) Nm at 2900 (or 3000) rpm.
With the addition of a DOHC cylinder head on the G4FK, the power output raised to 101 hp (75 kW) at 5800 rpm and 98 lb·ft (133 N·m) at 3000 rpm.
The turbocharged SOHC Alpha, also introduced in 1993, produced 115 hp (86 kW) at 5500 rpm and 123 lb·ft (167 N·m) at 4500 rpm. This engine was equipped with a Garrett T15 turbocharger.
1.6
The Alpha was updated in 2003 and debuted in the Accent economy car. The G4ED Alpha II was enlarged to 1.6L (1599 cc) thanks to a 76.5 mm bore and 87 mm stroke. A 10:1 compression ratio produced 104 hp at 5800 rpm with 106 lb·ft of torque at 4500 rpm. Continuously variable valve timing (intake side only) was added in 2006 along with a 4 mm larger throttle body, which boosted power to 110 hp at 6000 rpm with torque remaining the same. The Rio, which used the same engine, was rated at the same hp but 107 lb·ft.
The 2006-2011 Alpha II uses a cast iron engine block and aluminum DOHC cylinder heads with 4 valves per cylinder. It uses MFI fuel injection and features forged steel connecting rods. It has COP (Coil-On-Plug) ignition, graphite-coated pistons and new cylinder block design to increase strength. Throttle body bore has increased from 48 to 52 mm. The power and torque spread of the engine is across a wider range of engine speeds due to CVVT. Engine and automatic transmission control is now integrated into one module and the PCM is located in the engine compartment. It is ULEV-certified in all 50 U.S. states. The Alpha engine family is produced in Ulsan, South Korea.
