The M 166 is a four- cylinder in-line petrol engine from Mercedes-Benz , which was installed in the A-Class from 1997 and in the Vaneo from 2001 . The M 266 is the largely identical successor model that was installed in the A-Class and B-Class from 2004 .
With the new edition of the A- and B-Class from 2011 and 2012, respectively, these vehicles no longer have a sandwich floor. The successor engine to the M 266 is the M 270 .
The most comparable diesel engines with a similar shape are the OM 668 for the M166 and the OM 640 for the M266 .
technology
The petrol engine is an inline four-cylinder with eight valves and an overhead camshaft (OHC) driven by a timing chain . It has a light-alloy cylinder head and cylinder block, crankshaft with five bearings and electronically controlled fuel injection. It was specially developed for vehicles with the "sandwich" concept. In order to enable a more even weight distribution and the shortest possible front overhang (as well as a short overall length) of the vehicle, the engine is inclined at the front by 60 ° forwards (with its crankshaft center) behind the front axle. The crankcase and oil pan are already partially under the floor of the passenger cell ; in the event of a frontal crash, the engine slides under it to provide enough crumple zone for occupant protection. Only the cylinder head and the maintenance points are easily accessible in the engine compartment.

Planned versions with turbocharging and over 150 kW (200 hp) were put on hold because of the poorly dimensioned clutch of the A-Class.
As power transmission to the front axle , there were three different transmissions:
- 5-speed manual transmission
- 5-speed automatic converter
- AKS gearbox (automatic clutch system)
In the AKS transmission, sensors on the gear lever control the clutch. The driver only needs to select the gears using the H shift while the clutch is controlled automatically.
