It is the bestselling van in its class in Europe. Now the Mercedes-Benz Sprinter is consolidating its leading position even further, pulling away from its competitors with a new generation of diesel engines, new manual transmissions and numerous other features.
This comprehensive further improvement centres on the completely new four-cylinder diesel engines and the comprehensively re-engineered V6 engine. The development focus was on maximum environmental protection by virtue of compliance with the Euro 5 emission standard, and optionally even EEV, further improved economy with a lower fuel consumption, impressive performance with high output and torque, great responsiveness and even more operating refinement.
Four-cylinder OM 651: completely new design
The four-cylinder OM 651 diesel engine is a completely new design with a displacement of 2.15 litres and an undersquare configuration, with a bore of 83 mm and a stroke of 99 mm. This produces more torque, and therefore more pulling power and performance. The two overhead camshafts operate a total of 16 intake and exhaust valves. The camshafts are driven by a combination of gears and a short duplex chain. As before, a common-rail system is used to inject the fuel.
The maximum injection pressure has been increased to a remarkable 1800 bar in the new engine generation.
Top performance across the entire engine speed range
In the basic version, the engine is aspirated by a single-stage turbocharger with variable turbine geometry. Two-stage turbocharging is used in the other output variants. This combination allows top-class performance across the entire engine speed range. For the first time in a van, the new four-cylinder engines feature Lanchester balancers: two counter-rotating shafts lend these engines a level of smoothness never before achieved in this class.
The development engineers have also newly designed the ancillary units with a view to fuel economy. The oil pump, coolant pump and alternator are all demand-controlled units.
Four-cylinder engine: output increased by up to eight percent, torque by up to 14 percent
Three output variants of the new OM 651 four-cylinder engine with a displacement of 2.15 litres are available:
210 CDI/310 CDI/510 CDI:
Output 70 kW (95 hp) at 3800 rpm,
max. torque 250 Nm at 1400-2500 rpm
213 CDI/313 CDI/413 CDI/513 CDI:
Output 95 kW (129 hp) at 3800 rpm,
max. torque 305 Nm at 1200-2400 rpm
216 CDI/316 CDI/416 CDI/516 CDI:
Output 120 kW (163 hp) at 3800 rpm,
max. torque 360 Nm at 1400-2400 rpm.
V6 CDI: top model with ten percent more torque
With its brilliant technology, the three-litre OM 642 V6 engine is one of the masterpieces of Mercedes-Benz engineering. The latest version of this engine achieves the Euro 5 emission standard with a slightly increased output and significantly higher maximum torque. At the same time fuel consumption has been significantly reduced. Further developments in the V6 also include a rail pressure of up to 1800 bar. A particulate filter continues to be standard equipment. Figures for the OM 642:
219 CDI/319 CDI/419 CDI/519 CDI:
Output 140 kW (190 hp) at 3800 rpm,
max. torque 440 Nm at 1400-2400 rpm.
Exhaust gas recirculation is sufficient for Euro 5 in vans
Thanks to the very high level of engine efficiency, the Mercedes-Benz Sprinter is able to achieve both Euro 5 and EEV with exhaust gas recirculation alone. Naturally all the new engines also feature a particulate filter as standard. The new engines in the OM 651 series will initially be introduced in all Sprinter versions registered as trucks in markets introducing Euro 5 from a gross vehicle weight of 3.5 t in the autumn. Introduction for models registered as passenger cars will follow.
ECO Gear: new six-speed manual transmission for vans
The likewise new ECO Gear six-speed manual transmission also makes a major contribution to fuel economy and the improved driveability and agility of the Sprinter. The outstanding feature of this new transmission is a particularly wide ratio spread, with a low-ratio first gear and a high sixth gear for lower engine speeds.
Fuel consumption reduced by 0.6 to 1.5 litres/100 km
The generally low engine speed levels and the numerous technical innovations considerably reduce fuel consumption. Depending on the output variant, the NEDC fuel consumption is between 0.5 and 1.0 litres per 100 km lower than that of the preceding models. The difference is even greater in the case of the V6 CDI: depending on the configuration, a lower NEDC consumption by up to 1.5 litres per 100 km is achievable.
Comfort and safety increased by numerous new features
Numerous new features have been introduced in the Sprinter together with the new engines. As a result the permissible trailer load of the 3.5-tonne Sprinter has been increased to the same figure, 3.5 tonnes.
Mercedes-Benz has also improved the exemplary safety of the Sprinter even further. ESP trailer stabilisation recognises sinusoidal oscillations around the vertical axis of the vehicle, and initiates counteraction with active braking intervention. Adaptive brake lights are now standard equipment in every Sprinter: the brake lights flash rather than merely light up during the critical braking manoeuvre, thereby warning traffic behind in hazardous situations. If the customer chooses the option “Heated and electrically adjustable exterior mirror”, the wide-angle mirror is now also heated.
The high level of comfort in the Mercedes-Benz Sprinter is enhanced by new front seat upholstery with improved air permeability. A universal interface is also optionally available for connecting mobile electronic devices such as navigation systems or an MP3-player. The new, wireless hands-free system has a similar purpose and is suitable for Bluetooth telephony.
