Launching new era in diesel technology

Press Release

Launching new era in diesel technology

Spiralling fuel prices have also increased the demand for economical, clean cars in the USA. Mercedes-Benz is launching the new E 320 BLUETEC on October 15, timed to coincide with the introduction of low-sulphur diesel fuel in the USA. This model is also one of the most economical vehicles in its class and is regarded by experts as the pioneer of a new diesel era.

The introduction of clean diesel fuel in the USA represents an opportunity we have been battling for long and hard, the sort of opportunity we intend to utilise fully from day one”, explained Dr Thomas Weber, head of Development at DaimlerChrysler AG and at the Mercedes Car Group, during the E 320 BLUETEC presentation in Las Vegas, Nevada. Background: state-of-the-art diesel vehicles, which already account for more than half of annual new registrations in Western Europe, have not yet realised their full potential in the USA due to excessive sulphur levels in existing fuel. All that is about to change with the nationwide introduction of clean diesel fuel with a sulphur content of just 15 ppm. “Ultra Low Sulphur Diesel” (ULSD) will be on sale at up to 76,000 US filling stations during the initial stage and will help promote the adoption of BLUETEC. This innovative diesel technology will also enable Mercedes-Benz to meet the world's most stringent emission limits for nitrogen oxides, providing the right conditions for state-of-the art diesel technology to make its mark in the USA.

BLUETEC power is about to win many friends in North America as soon as US customers get behind the wheel of a car like the E 320 BLUETEC”, says Dr Thomas Weber. “Our 208 hp three-litre V6 develops eight-cylinder-like torque of 400 pounds feet (540 Nm) combined with the sort of economy you get from a four-cylinder engine in everyday use.” The combined consumption of just 6.7 l/ 100 km (35 miles per US gallon) provides a range of 700 miles (around 1200 km) without having to refuel.

Ultra-modern diesel vehicles provide their owners with assured, clean and economical driving pleasure and can potentially – given a sufficiently large uptake – make national economies less dependent on oil imports. An EPA study dating back to 2004 confirmed the enormous potential savings inherent in diesel. Margo Oge, Director of the Office of Transportation and Air Quality, came up with the following calculation: if just a third of the light-duty vehicles in the USA were state-of-the-art diesel vehicles, we would be looking at saving 1.4 million barrels a day, the equivalent quantity of oil the USA imports from Saudi Arabia every day.

With no end in sight to soaring fuel prices, experts predict a greater uptake of diesel around the globe. The recent J.D. Power study “Global Outlook For Diesel” forecasts that the current global diesel market share of 18 percent is set to reach around 30 percent in 2015: diesel vehicles are expected to account for over 15 percent of new registrations in North America.

Additional BLUETEC models in the USA and Europe by 2008

Against this background, Mercedes-Benz intends to systematically broaden its BLUETEC portfolio. Dr Weber: “In addition to the E 320 BLUETEC we aim to have another three BLUETEC models in the line-up as early as 2008 that meet the 50-state BIN 5 standard in the R-Class, ML-Class and the GL Class.” Following its launch in the USA, Mercedes-Benz intends to successively roll out BLUETEC in other markets. At present the technology is being adapted to European market requirements and other Mercedes Benz models. The company’s European customers should have the option of BLUETEC in a passenger car by 2008 at the very latest. Meanwhile the Jeep Grand Cherokee BLUETEC concept is a perfect example of how other DaimlerChrysler brands can also leverage BLUETEC.

BLUETEC is a modular emission control system that reduces nitrogen oxides. Diesel engine design means nitrogen oxide is currently the only emissions constituent that exceeds the equivalent figure for a petrol unit. Mercedes-Benz has developed BLUETEC in two versions: in the E-Class an oxidation-type catalytic converter and particulate filter are combined with an improved, extremely durable NOx trap system and an additional SCR catalytic converter. The second BLUETEC version is even more efficient. Here, AdBlue, a non-toxic aqueous solution, is injected into the exhaust-gas stream, causing ammonia to be released. In the downstream SCR catalytic converter the ammonia then converts up to 80 percent of the nitrogen oxides into the harmless natural products of nitrogen and water. The specific vehicle concept and weight as well as the deNOx requirements determine which BLUETEC system is used. In principle, BLUETEC is capable of meeting the world’s most stringent exhaust emission standards.

The world’s cleanest diesel: First series-produced passenger car with BLUETEC from Mercedes-Benz

  • Advanced diesel technology represents a superior drive concept
  • High performance, extremely economical fuel consumption, long range and the lowest emissions ever
  • BLUETEC’s ability to meet even the most stringent emission limits means diesel technology is now ready for the future

BLUETEC technology is making Mercedes-Benz the pioneer of a new generation of clean and powerful high-tech drives, whose highly effective exhaust gas treatment systems give them the potential to fulfill the world’s most stringent emission limits in the future. At the same time, the basic technology for turbo-charging and common-rail direct injection used in Mercedes CDI diesel engines has already proved itself in millions of vehicles in Europe.

BLUETEC ensures that diesel drives will continue to offer outstanding driving pleasure in the future, especially in the U.S. What’s more, in view of continually rising fuel prices, BLUETEC represents a superior drive concept for both today and tomorrow.

The Mercedes-Benz E 320 BLUETEC offers outstanding driving dynamics and unprecedented efficiency and environmental compatibility. Its three-liter V6 engine combines the powerful torque of a high-volume V8 engine with the low fuel consumption of a compact model. The vehicle accelerates from 0 to 60 mph in just 6.6 seconds, making it one of the sportiest executive sedans on the market. Its tremendous torque of 400 lb-ft even exceeds that of most eight-cylinder engine models. At the same time, the Mercedes-Benz E 320 BLUETEC gets 35 miles per gallon (6.7 liters/100 km) in combined cycle driving. That’s a level of fuel efficiency normally found only in a compact car. The vehicle is also environmentally friendly through its excellent fuel economy and its extremely low emissions.
