In 1979, the all new Lancer EX was unveiled in Japan. Its new, clean and aerodynamic styling with integrated plastic bumpers reflected that of the recently introduced Galant and Sapporo. It was of a more European appearance than earlier Mitsubishi vehicles.[9] Considerably more spacious, it grew in all dimensions.[9] Only two engines were offered at first, a 1.4-liter MCA-JET equipped engine paired with Mitsubishi’s Silent Shaft Technology, which generated 80 PS (59 kW) and a 1.6-liter engine that generated 85 PS (63 kW). The MCA-JET system was an entirely new concept when compared with the previously used carburetor system. The MCA stands for Mitsubishi Clean Air which meant that the EX passed both Japan and US emission standards, while the new cylinder head design of the engine gave way for a Jet valve which introduced an extra swirl of air to the combustion chamber, swirling the fuel-air mixture for a cleaner, efficient and more thorough burn.

In addition to these improvements, another breakthrough in the Lancer lineup was the Silent Shaft Technology, which was actually two counterbalancing shafts that rotated in opposite directions, cancelling the power pulses inherent in an inline four-cylinder engine. This reduced both engine noise and vibration, and provided a smoother driving experience. The 1.8-liter Sirius 80 engines were then introduced in the Lancer in 1980, expanding the Lancer’s range of engines. Also, a turbocharged, 135 PS (99 kW) engine was added in 1980 for sportier performance, and an intercooler system was also integrated in the existing turbocharged engine to produce 160 PS (118 kW) in 1983.
In 1980, The Lancer EX was introduced with a 1.8-liter turbocharged inline-four option known as the 1800GSR and GT Turbo. The first generation 1800GSR and GT were only available with a turbocharged, non-intercooled 135 PS (99 kW).
New Zealand importer Todd Motors assembled the new Lancer EX from 1980 with 1.6-liter carburetor gasoline engine and a choice of manual or automatic transmission. The model was also a popular base for rally cars in that market, with some success. It was replaced by the front-drive Tredia in 1982 with the Cordia coupe equivalent effectively replacing the earlier Celeste.
EuropeEdit
In Europe, the Lancer EX sold well as its restrained styling better matched the desires of European buyers than its somewhat fussy predecessor. Other considerations concerned handling and also the demand for more passenger room, as Mitsubishi tailored the Lancer towards European consumers. It went on sale locally after making its European premier at the 1979 Frankfurt Show.[10]
Unlike in Japan, European buyers could also get a 1.2-liter option which suited local tax conditions. Claimed outputs in Europe were lower than in the domestic market, with the 1200, 1400, and 1600 being good for 40, 50, and 60 kW (54, 68, and 82 PS) respectively.[9] Here, the Lancer EX was also offered with a turbocharged 2.0-liter engine, known as the Lancer EX 2000 Turbo. It achieved a maximum output of 125 kW (170 PS) and managed a top speed of 200 km/h (124 mph). This model was equipped with multi point fuel injection(ECI). A rally version of the Lancer EX 2000 Turbo was made for the 1000 Lakes Rally that gave out 206 kW (280 PS). At home, sales of the turbo model were low because of emission regulations Japan imposed at that time.
