Economical, environmentally friendly, high-performance and user-friendly for the driver – modern-day drive technology for professional users. This is the perfect combination offered by the new generation of diesel engines in the Mercedes-Benz Vito.

Hundreds of thousands of these engines have already proven their worth in the Mercedes-Benz Sprinter van and in diverse Mercedes-Benz passenger cars. The new Vito sets the benchmark in economy and environmental friendliness. All engines comply with the Euro 5 emissions standard. Drastically reduced fuel consumption also lowers CO2 emissions to a record level. Substantial further reductions in fuel consumption and emissions are possible with the optional BlueEFFICIENCY package (standard for the Vito crewbus licensed as a passenger car). This innovative package is kind on both the environment and the company budget, and is not to be found in any other van.

All diesel engines are equipped with an oxidation catalytic converter, a particulate filter and cooled exhaust gas recirculation. The new ECO Gear manual transmission offers a broad gear ratio spread for optimum performance and enables low fuel consumption and emission levels. The Vito is the only model in its class to feature a six-speed transmission for all four-cylinder drive variants as standard. The overall result is impressive response and acceleration combined with outstanding economy, environmental friendliness and smooth running. Top of the range is the V6 in the Vito 122 CDI, which combines smooth running with impressive output and high tractive power to meet the very highest requirements. The latest version of this engine is also more powerful, more economical and more environmentally friendly. The new engine ratings are accompanied by corresponding changes to the numerical codes in the Vito model designations.

Four-cylinder CDI: robust, economical, clean, powerful and smooth-running
At the core of the new generation of engines is the four-cylinder in-line unit which has the internal code OM 651. It is available in three power variants for the Mercedes-Benz Vito:

*Basic vehicle with standard roof, rear-wheel drive and manual transmission

This represents an overall rise in power output and torque in comparison to the predecessor models, with major increases in some instances. At the same time, fuel consumption and CO2 emissions have been reduced substantially – by up to 15 percent, depending on the engine variant. Apart from attaining surprisingly good values in absolute terms for its size and weight, the Vito clearly leads its class in terms of fuel economy and CO2 emissions.

High tractive power, durable chain-type camshaft drive
State-of-the-art engine technology provides the basis for the Vito’s exceptionally low fuel consumption and CO2 emissions. The high torque of the long-stroke engine with 83 mm bore and a stroke of 99 mm provides for unusually high tractive power. The two overhead camshafts actuate a total of 16 inlet and exhaust valves via cam followers with hydraulic valve clearance compensation.

The camshafts are driven via a combination of gearwheels and a short chain, providing the robust basis for a virtually endless service life. This is especially advantageous in tough commercial use involving high mileage and high levels of stress and strain.

Fuel injection takes place by means of a common rail system. Particularly durable solenoid valves and seven-hole injection nozzles provide for extremely precise fuel injection with up to five injections per combustion cycle. The benefits of this technology include a gentle build-up of pressure and a smooth-running engine. The maximum injection pressure stands at an impressive 1800 bar.

Charging is carried out in both power variants by a turbocharger with variable turbine geometry which combines high efficiency with swift response to movements of the accelerator pedal. Maximum torque is available right from very low engine speeds and over a broad rev range – another key benefit in commercial operations requiring high tractive power. Thanks to its combination of a rated engine speed of 3800 rpm and astounding elasticity, the four-cylinder engine has an unusually broad useful operating range between around 1000 and 4000 revs. This is unmatched by any other diesel engine in this class of vehicle.

Balancer shafts for all variants ensure unparalleled smooth running
Drivers of vans from Mercedes-Benz are not required to compromise on comfort. Common rail injection, the low-vibration forged crankshaft running on five bearings and the rear camshaft drive provide the foundation for the engine’s surprisingly smooth running. All four-cylinder engines also benefit from Lanchester balancing, with two counter-rotating shafts running under the crankcase, driven by spur gears. Mercedes-Benz is the only manufacturer in this vehicle class to deploy balancer shafts in all four-cylinder engines of its vans – commercial vehicles from Mercedes-Benz embody the same pioneering quality for which the brand’s passenger cars are renowned.

Unique to Mercedes-Benz: particularly economical demand-responsive auxiliary units
The development engineers have also devoted great attention to optimising the auxiliary units. The oil pump is a controlled vane-type pump featuring electrical actuation, for example. It controls its delivery rate automatically according to the given requirements, as does the controlled fuel pump. This reduces the power output, thereby lowering fuel consumption. The coolant pump also adjusts automatically to the given requirements, further helping to reduce fuel consumption. The same goes for battery management, with the alternator charging only when necessary.

Tuned to perfection: the ECO Gear six-speed manual transmission
The new six-speed ECO Gear manual transmission comes as standard for all Vito models equipped with a four-cylinder diesel engine. This transmission is a substantial contributory factor to the reduced fuel consumption and further enhanced dynamic performance of the Vito CDI. Its defining feature is a particularly broad gear ratio spread, with a short first gear (i=5.076) and a long sixth gear (i=0.675) designed to keep the engine speed low.

This configuration accords due consideration both to typical situations such as hill starts with full payload and loaded trailer and to long journeys on the motorway. Overall, the engine speed has been reduced substantially in the interests of lower fuel consumption and emissions. Another consequence of this strategy is a noticeable improvement in ride comfort.

The particularly user-friendly and well-proven five-speed automatic transmission is alternatively available for the Vito. It comes as standard for the Vito 122 CDI and Vito 126.

V6 CDI: an impressive feat of engineering goes one better
The V6 engine in the Vito 122 CDI is an accomplished feat of engineering and a pinnacle of engine design from Mercedes-Benz. The only six-cylinder engine to be deployed in a van attains impressive performance data for a diesel in this class, providing the basis for a special driving experience. The engine is based on an aluminium crankcase with a V angle of 72 degrees. Thanks to offset connecting rod journals, the engine runs more smoothly than any other diesel in its class. The technical highlights include a total of four chain-driven overhead camshafts, common rail injection with piezo injectors and eight injection holes per injector for ultra-fine atomisation of the fuel.

The latest version of the engine in the Vito 122 CDI offers ten percent more power, at 165 kW (224 hp) and an unchanged highly impressive level of torque, at 440 Nm. It complies with the Euro 5 emissions standard. At the same time, fuel consumption and CO2 emissions have fallen noticeably, by around five percent, and are surprisingly low in relation to the performance capabilities of the Vito 122 CDI. Other enhancements of this latest version of the V6 include a maximum injection pressure of 1600 bar. Key data:

Vito 122 CDI (figures differ according to variant)
– Power output 165 kW (224 hp) at 3800 rpm
– Max. torque 440 Nm at 1400-2800 rpm
– Fuel consumption in acc. with NEDC 8.6 l/100 km
– (Vito 122 CDI BlueEFFICIENCY 8.4 l/100 km)
– CO2emissions 226 g/km (BlueEFFICIENCY 221 g/km)
– Top speed 201 km/h
– Acceleration 0-100 km/h in 9.1 seconds

Its impressive performance data, its unmatched smooth running and its impressively low fuel consumption and emission levels make the new generation of the Vito 122 CDI a unique contender in its class which meets the very highest standards. The engine comes exclusively with a well-proven and particularly user-friendly automatic transmission.

Vito 126: in a class of its own
The Vito 126 with its V6 petrol engine is also in a class of its own. The power delivery and smooth running of this six-cylinder engine are unmatched in any other van. The latest version of the Vito 126 complies with the Euro 5 emissions standard. This engine also employs an automatic transmission. Key data:

Vito CDI 126.5 (figures differ according to variant)
– Power output 190 kW (258 hp) at 5900 rpm
– Max. torque 340 Nm at 2500-4000 rpm
– Fuel consumption in acc. with NEDC 11.9 l/100 km

BlueEFFICIENCY: clean and economical like no other
First announced by reference to a study at the IAA Commercial Vehicles fair in 2008, the vision of BlueEFFICIENCY technology has now become reality, reducing fuel consumption and emissions in the Mercedes-Benz Vito. It is available as an option for the Vito panel van and comes as standard in the Vito crewbus licensed as a passenger car. A label below the A-pillar confirms that BlueEFFICIENCY is on board.

The scope of the package is unique in the vans segment: ECO start/stop function (not for automatic transmissions), battery management, tyres optimised for minimum rolling resistance, ECO power steering pump, shift point indicator (not for automatic transmissions), a controlled fuel pump and internal engine measures demonstrate the cutting-edge technology involved.

The BlueEFFICIENCY package combines sustainability and economy in exemplary fashion. It further reduces the Vito’s traditionally low fuel consumption by an additional 0.2-0.3 litres per 100 km (6.75 g of CO2 per km) in the new generation, according to model and engine variant.

Long maintenance intervals also contribute to the Vito’s sustainability and economy. The ASSYST service computer which comes as standard calculates oil-change intervals on a flexible basis according to the actual use of the vehicle. The average interval across all engines stands at 30,000 km or two years. Higher mileages are also possible between oil changes, depending on the intensity of use and the individual driving style.

Further enhanced Vito 4×4 all-wheel drive
The Vito 4×4 with permanent all-wheel drive and variable power distribution by means of the 4ETS traction system also benefits from numerous innovations. A new 3-point bearing for the front-axle transmission and an increased oil volume reduce vibration and wear on the all-wheel drive. Helical gearing for the differential provides for smoother running. As previously, the Vito 4×4 is available exclusively in conjunction with the two higher power variants of the four-cylinder engine and automatic transmission (Vito 113 CDI/116 CDI 4×4). The Vito 4×4 now also complies with the Euro 5/III emissions standard.
