The Mercedes M271 E16 engine was produced from 2008 to 2011 and was developed on the basis of the M271 E18 cylinder block, where the corresponding short-stroke crankshaft was installed (the stroke was reduced to 75.6 mm). The M271 E16 is a 1597cc inline 4-cylinder petrol engine.

R4 Mercedes engines: M102, M111, M166, M254, M260, M264, M266, M270, M271 E16, M271 E18, M274, M282.
The cylinder block is cast from aluminum with cast-iron sleeves poured into it. At the bottom of the block is a Lanchester balancing mechanism with two balancing shafts and an integrated oil pump.

Disadvantages of the M271 E16 engine
- The most famous engine problem is the stuck exhaust valves due to soot.
- In second place is the unreliable timing chain, which can stretch up to 100,000 km.
- This is followed by frequent lubricant leaks from the oil filter housing or heat exchanger.
- The crankcase ventilation system quickly becomes dirty, so much so that the tubes burst.
- A proprietary malfunction of the EVO series engines is the ingress of fuel into the oil.
