Since 2006, the company has produced the 2.0-liter 16-valve Mitsubishi 4B11 engine, which is found in its most well-known models, including the ASX, Outlander, Lancer, and Eclipse Cross. Similar to the Chrysler ECN, Hyundai G4KA, and G4KD, this unit was developed as part of a single alliance.

The Global Engine Manufacturing Alliance was established in 2002 by Hyundai, Mitsubishi, and Chrysler. A new range of 1.8, 2.0, and 2.4 liter petrol powertrains was unveiled in 2004. Production of the 2.0-liter 4B11 engine, along with its Hyundai G4KA and Chrysler ECN counterparts, began in 2006. Distributed injection, an aluminum block with cast-iron sleeves, an aluminum 16-valve DOHC block head without hydraulic lifters, and a timing chain drive are all features of the same design. MIVEC phase shifters, either on the intake or on both shafts, set the Mitsubishi engine apart. A more contemporary unit with the 4J11 index was later developed based on such a motor.
The engines 4B10, 4B11T, and 4B12 are also part of the 4B1 family.
The engine was mounted on:
- Mitsubishi ASX 1 (GA) since 2010;
- Mitsubishi Delica 5 (CV) since 2007;
- Mitsubishi Eclipse Cross 1 (GK) since 2017;
- Mitsubishi Lancer 10 (CY) in 2007 – 2017;
- Mitsubishi Outlander 2 (CW) in 2009 – 2012;
- Mitsubishi Outlander 3 (GF) since 2012;
- Peugeot 4007 I (I3) in 2008 – 2012;
- Peugeot 4008 I (J3) in 2012 – 2017.

Disadvantages of the Mitsubishi 4B11 engine
Although this motor is thought to be very dependable, it is prone to oil consumption at high mileage because of piston rings or wear on the seats and valve guides. Like any aluminum block with an open jacket, there is also an ellipse of cylinders.
Stretching the timing chain to 150,000 kilometers is the second most common issue. If you don’t experience significant wear on the phase regulator sprockets, replacing the timing kit won’t be too expensive.
The motor’s noisy operation, frequent lubricant leaks, exhaust pipe ring burnout, and the emergence of cracks in the exhaust manifold’s base are other common complaints. Additionally, since there are no hydraulic lifters here, remember to adjust the valves’ thermal clearances.
