The Mitsubishi Orion or 4G1 engine is a series of inline-four internal combustion engines introduced by Mitsubishi Motors in around 1977, along with the Astron, Sirius, and Saturn. It was first introduced in the Colt and Colt-derived models in 1978. Displacement ranges from 1.2 to 1.6 L (1,244 to 1,584 cc).
4G11[]
The 4G11 displaces 1.2 L (1,244 cc) with a bore and stroke of 69.5 mm × 82 mm (2.74 in × 3.23 in).
Applications:
- Mitsubishi Colt/Mirage A151A
- 1977.04-1979.03 Mitsubishi Lancer A141A
- 1979.03-1985.02 Mitsubishi Lancer Van A141V/A148V
- 1979.11-1983 Mitsubishi Lancer EX A171A
4G12[]
The 4G12 (also known as the G11B) displaces 1.4 L (1,410 cc) with a bore and stroke of 74 mm × 82 mm (2.91 in × 3.23 in). 4G12 was the first to feature Mitsubishi's MD (modulated displacement) technology, a form of variable displacement which shut off two cylinders during light load and at low speeds. The 4G12 was not offered by Mitsubishi with fuel injection. This engine is fairly outdated compared to its counterparts that were used in the later Lancers.
Applications:
- Mitsubishi Colt/Mirage A152A
- 1978.04-1979.03 Mitsubishi Lancer A142A
- 1979.03-1985.02 Mitsubishi Lancer Van A142V/A149V
- 1978.04-1981.07 Mitsubishi (Lancer) Celeste A142
- Mitsubishi Lancer EX A172A
- Mitsubishi Tredia/Cordia A211
- Dodge/Plymouth Colt
- Plymouth Champ
4G12T[]
This is the turbocharged version of the 4G12, uses a TC-04 turbocharger from Mitsubishi Heavy Industries.[1] The diameter of the blades in this charger is rather small, at 49 mm, and it spins at 90,000 rpm to provide 0.53 bar (7.7 psi) of boost. This increased power and torque by about 30 and 25 percent respectively.[1] The Japanese-specification version of this engine produces 105 PS (77 kW) at 5,500 rpm and 15.5 kg⋅m (152 N⋅m; 112 lb⋅ft) of torque at 3,000 rpm.[2]
4G13[]
The SOHC 4G13 displaces 1.3 L (1,298 cc) 12 valves 75–85 hp (56–63 kW) with a bore and stroke of 71 mm × 82 mm (2.80 in × 3.23 in). In the Gulf Countries, 90 PS (66 kW) gross at 6000 rpm is claimed on the mitsubishi lancer CB1.[3]

The SOHC 4G15 displaces 1.5 L (1,468 cc) with a bore and stroke of 75.5 mm × 82 mm (2.97 in × 3.23 in). A version of the 4G15 was produced with gasoline multi-port fuel injection. It has approximately 94 hp (70 kW) on the 1993 Mirage model. The DOHC 4G15 produces 109 hp (81 kW) with 137 N⋅m (101 lb⋅ft) of torque. Another DOHC version was combined with GDI fuel injection and delivers 100 hp (75 kW) and 137 N⋅m (101 lb⋅ft) of torque. A DOHC MIVEC turbo variant of the engine is also still in production to date (4G15T), serving in the Mitsubishi Colt series, offering 163 hp (122 kW) on the latest Colt Version-R (with exhaust enhancement). The most powerful version of this engine is found in the Colt CZT Ralliart (special model in Switzerland) with a total output of 197 hp (147 kW). There was a recorded instance of the engine exceeding 997,000 mi (1,604,516 km) in a 1998 Mitsubishi Mirage sedan.
The 4G15 is known as one of the longest living Japanese engines ever produced where new variants of the engine are still being produced and used in Chinese cars since 2005. The new engines have been produced by GAC Mitsubishi Motors, a joint venture from the Hunan province in southern China, since April 2017.[4]
