Mitsubishi Outlander engines
The Mitsubishi Outlander is a compact crossover SUV manufactured by Mitsubishi Motors from 2001 to the present. At the beginning of sales in the domestic Japanese market, it was positioned as Mitsubishi Airtrek. The car is manufactured in the third generation at factories in Japan, the Netherlands, India, Thailand and Russia. The name of the car – Outlander – means “in search of adventure.” In 2014, the 3rd generation car underwent restyling. The changes affected the appearance, optics, suspension, ventilation and noise insulation of the cabin.
The Mitsubishi Outlander was offered with 12 engines since 2001 (10 petrol, 2 diesel). Displacement ranges from 2.0 to 3.0 liters, power output from 87 to 291 hp. 7 use a timing chain and 6 a timing belt. 3 are turbocharged. The longest rated lifespan belongs to the Mitsubishi 4G63 (about 400,000 km).
