Mercedes M270 gasoline engines with a capacity of 1.6 and 2.0 liters were produced from 2011 to 2019 and were installed in models with transversely mounted engines, such as the A-Class and B-Class. Similar power units for vehicles with longitudinally mounted engines are designated M274. R4 Series: M102, M111, M166, M260, M264, M266, M271, and M282.

The weight of the M270 engine according to the catalog is 137 kg. The M270 engine number is located at the junction of the block with the gearbox. Cracking of the phase regulators: In engines prior to 2014, the phase regulators quickly failed and started to crack, then they were updated and the problem started to manifest much later, but did not disappear completely. It does not have a high resource for the timing chain, usually it is replaced every 100-150 thousand km. Impulse disk displacement: In engines of this family, the impulse disk is pressed onto the camshaft and gradually shifts with each start. The process is especially accelerated by a stretched timing chain. This is the main reason for the starting problem of the engine, up to complete failure. Piston damage: In 2015, power units of this series received a different firmware and became more economical, however, immediately there were reports of replacing damaged pistons due to detonation. Poor quality fuel also significantly reduces the life of direct injection piezo injectors. Engine overheating: It is necessary to carefully monitor the condition of the cooling system of this unit, as the cylinder head heats up very quickly, even from a not very long overheating. This problem is exacerbated by the presence of an unreliable thermostat and water pump. Other breakdowns: Leaks often occur due to a stuck crankcase ventilation valve, as well as from the gasket of the heat exchanger or from the front crankshaft seal. Due to wiring breaks, the variable capacity oil pump valve hangs, fuel hoses leak, the turbocharger actuator gets stuck, and the adsorber quickly clogs.

Mercedes M254 engines with capacities of 1.5 and 2.0 liters were introduced for the first time in 2020 and are characterized by plasma-sprayed iron with a Nanoslide coating and an integrated starter-generator (ISG). Currently, these power units are only installed in the fifth generation of the popular C-Class model. R4 series: M166, M260, M264, M266, M270, M271, M274, and M282.
4-cylinder Mercedes M266 engines with a displacement ranging from 1.5 to 2.0 liters were produced from 2004 to 2012 and were exclusively installed in the compact A-Class model and its compact van counterpart, the B-Class. These power units were essentially just updated versions of the popular M166 engines. R4 Series: M111, M260, M264, M270, M271, M274, and M282.
The V6 engines of the Mercedes M272 series, with a displacement ranging from 2.5 to 3.5 liters, were produced from 2004 to 2017 and installed in the most popular models of the group, such as W204, W211, and W221. There were also specially powerful versions of this engine called Sportmotor. Also belonging to the V6 lineup are the engines: M112 and M276.
The V6 engine series with a displacement of 3.0 and 3.5 liters, the Mercedes M276, was introduced in 2010 and has since been installed in most of the company's modern models, such as the W205 and W222. There are three variants of this engine: naturally aspirated and two with turbocharging. The V6 engine line also includes the engines: M112 and M272.
The 1.6-liter Volkswagen AVU 8v engine was produced by the company from 2000-2002 and was installed in Audi A3, VW Golf 4 and Bora models, as well as Skoda Octavia. This unit complies with Euro 4 standards and is equipped with an electric throttle, secondary air injection system, and EGR valve. EA113-1.6 series: AEH AHL AKL ALZ ANA APF ARM BFQ BGU BSE BSF
The 2.4-liter Nissan KA24E engine was produced from 1988 to 1999 and used in many models, but it is most well-known for being used in the Pathfinder and Terrano off-road vehicles.
