Mercedes Benz makes two  2.7L engines. One is designated the OM612, and the other is the OM647. Both are inline 5 cylinder diesel engines and GotEngines.com has both Mercedes 2.7L diesel engines for sale. Used in the C – / CLK – / E – and ML -Class, Sprinter and Mercedes G-Wagon Army vehicles.
A five cylinder engine sounds odd, however a 5-cylinder engine has a smoother torque curve than a four or a six. Having to do with the number of degrees of rotation in each power stroke. If a 4-stroke internal combustion engine [ICE] produced torque for half a rotation out of 2 turns, even numbers of cylinders would be smoother, but the power stroke is less than 180 degrees.
A 5-cylinder engine is longer and costs more to manufacture than a comparable gasoline or diesel 4-cylinder engine, but some manufacturers like Mercedes feel these costs are outweighed by its greater smoothness.
The inline-straight-five cylinder engine is not well known in the auto industry in the US. Looking back about 20 some years, Audi (2.2 and 2.3-litre), Honda (Acura TL), Volvo (2.0-litre, 2.3 turbo and 2.4-litre), Fiat group (2.0 and 2.4-litre Super Fire series) and Mercedes diesels were the only manufacturers to adopt such a design.
Contrary to what you may believe, inline-five engines have many benefits to offer. Firstly, it has a viable use in crossing the gap between 4 and 6-cylinder engines, thus in theory offers the best cylinder capacity for operating efficiency.
Secondly, compared with 4-cylinder engines, it eliminates one internal anti-vibration balancer shaft.
Thirdly, compared with 6-cylinder engines, it is short enough in length to be fitted transversely [transverse is front wheel drive where the engine mounts side to side, or east to west] into the engine compartment of front-wheel-drive cars.
Lastly, it can be produced from a current modular design of a 4 and 6-cylinder inline engine, saving development cost but also eliminating the investment of a new production line.
A straight Five diesel engine is currently available in the Chevy Colorado, GMC Canyon and Hummer H3 where it makes 220 hp and 225 lb.-ft. of torque, compared to the 4.3L gasoline V6 which makes 200 hp and 260 lb.-ft.
