Emission standards: Is 95 g of CO2 per kilometer by 2020 a realistic target?
Fleet targets: The ambitious CO2 targets for vehicle fleets cannot be achieved without diesel. Indeed, diesel engines will make a significant contribution to the aim of reducing the CO2 emissions of vehicle fleets to 95 g/km, and this at little extra cost.

The sub-compact class: At present, the most efficient diesels in this class emit some 80 grams of CO2 per kilometer. There is potential for savings of another six to nine percent. By applying a range of modifications to the vehicle, the CO2 emissions of sub-compact diesel vehicles can be reduced to less than 70 g/km.

The compact class: The most efficient diesels in this vehicle class currently emit 103 grams of CO2 per kilometer. The figure can be further reduced to less than 90 g/km. Optimizing the conventional diesel engine can cut emissions by up to 15 percent.

Sedans/SUVs: Compared with current vehicles in this class, an improvement of 9 to 14 percent can be achieved with technical measures similar to those applied in the compact vehicle segment.

Environment: How clean is diesel technology?
CO2: Diesel vehicles emit up to 25 percent less CO2 than comparable vehicles with gasoline engines.

Particle emissions (1): Since the first emissions legislation was introduced in 1990, particle emissions have been reduced by about 98 percent. In fact, today's efficient diesels have practically no particle emissions.

Particle emissions (2): Today, the efficiency of particle filters is well over 95 percent. This means that they filter even the smallest nano-particles efficiently.

Particle emissions (3): If a modern diesel engine is left running in neutral in a warehouse for 100 minutes, the particle emissions are equal to those of one smoked cigarette (measured as distributed throughout the entire warehouse).

NOx (1): Since the first particle emissions standard was introduced in 1990, nitrous oxide emissions have been reduced by about 98 percent.

NOx (2): By combining additional systems such as the Bosch Denoxtronic with an SCR catalytic converter, the nitrous oxide emissions of diesel engines can be reduced even further.

Fuel consumption: When is a diesel worth buying?
Overall: In a test that compared about 400 vehicle pairs, the German motor club ADAC reached the following conclusion: the higher the mileage, the more the diesel is a worthwhile purchase. For drivers that clock up 10,000 kilometers or more per year, opting for a diesel vehicle is worthwhile for 50 percent of all models.

Rule of thumb: The smaller the vehicle and the lower the mileage, the more likely it is that a gasoline engine is the better option.

Appeal: What makes a diesel worth driving?
Range: On average, a diesel in Europe can drive 1,020 kilometers on a single tank of fuel – 40 percent further than a gasoline engine. The Peugeot 508 with 115 horsepower is the model with the longest range: it drives 1,800 kilometers before it needs to be refueled. This means that a driver could travel from Hamburg to Moscow without stopping.

Fuel consumption: In terms of fuel consumption, the diesel is about 30 percent more efficient than a comparable gasoline engine.

Performance (1): The diesel provides 50 percent more torque than a comparable gasoline engine. Gasoline engines generally have a maximum of 7,000 rpm per minute. In contrast, a diesel engine achieves the same performance with about 4,500 rpm.

Newly registered vehicles: Diesel is booming
Germany: In 1980, less than one in every ten newly registered vehicles had a diesel engine. In 2012, almost half of new car buyers opted for a diesel.

SUVs and diesel: Especially in the SUV segment, which is seeing strong growth, car buyers are opting almost exclusively for diesel. In 2011, the market share of diesel engines in the large/SUV segment was over 80 percent.

The U.K.: Here, too, the share of diesel among newly registered vehicles has reached about 50 percent, and this despite the fact that diesel has been much more expensive than gasoline at U.K. service stations for years.

Japan: As recently as 2009, the Mercedes E-Class was the only diesel-powered sedan available on the market. Today, there are more than a dozen.

History: Bosch and the diesel engine
1922: Bosch officially began developing diesel injection systems

1927: Bosch manufactured the first injection pumps and nozzles

1936: Bosch delivered the first diesel injection system for passenger vehicles

1997: Bosch began series production of common rail systems for passenger vehicles; common rail for commercial vehicles followed in 1999.

2008: Bosch launched Denoxtronic for exhaust gas treatment in diesel passenger vehicles (Bluetech)
