For the 2009MY, Mercedes-Benz's Sprinter van has been updated with the introduction of a new generation of diesel engines and six-speed manual transmissions along with numerous, but of less importance, features. The new four-cylinder OM 651 diesel engine is a completely new design sharing only shares its overall displacement of 2.15-liters with its predecessor. It is available with three outputs (95HP and 250Nm, 129HP and 305Nm, 163HP and 360Nm) and complies with the stricter Euro 5 emission standard. 
The range-topping 3.0-liter V6 OM 642 diesel engine has been revised for 2009 producing a slightly higher (190HP at 3,800 rpm) output and a ten percent increase in maximum torque (440Nm at 1400-2400 rpm).
Both the four-cylinder and V6 diesel engines are offered with a new ECO Gear six-speed manual transmission with a low first gear and high sixth gear. The transmission is available in two versions, namely the ECO Gear 360 for the four-cylinder engines and the heavy-duty ECO Gear 480 with wider gear teeth and a more rigid housing for the six-cylinder diesel engine.
Other improvements for the 2009MY Sprinter include the enhanced ESP trailer stabilisation system, the new adaptive brake light, heated wide-angle mirror, lower position of the front foglamps and automatic transmission with Start-Off Assist plus a new wireless hands-free system and radio units.
