mercedes-benz m166

The M166 is a range of inline-four engines produced by Mercedes-Benz from 1997 to 2005, before it was succeeded by the M266 engine from 2004.
The M166 is transversely mounted and features 2 valves per cylinder with multipoint injection. The engine is used in W168 A-Class models that feature the 'sandwich concept', where the engine is mounted at a 59-degree angle just behind the front axle. This allows for better weight distribution as well as increased safety, as the engine slides underneath the floorpan instead of into the cabin in the event of a head-on collision....
