- 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
Las Vegas, Sept 06, 2006 — 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 (540 Nm) 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.
The BLUETEC concept utilizes state-of-the-art diesel engines featuring common-rail direct injection, thereby providing all the benefits this drive system has to offer. Fuel consumption in these diesel vehicles is 20 to 40 percent lower than in cars equipped with a comparable gasoline engine, and torque — the key indicator of engine power — is 30 to 50 percent higher.
The E 320 BLUETEC offers an impressive example of such attributes: Its torque of 400 lb-ft gives it the power of a vehicle equipped with a high-volume V8 gasoline engine, and its acceleration from 0 to 60 mph in just 6.6 seconds is an illustration of the model’s outstanding performance. The vehicle’s top speed of 155 mph (250 km/h) is, of course, a theoretical value in the U.S., but American customers are mainly interested in engines that deliver great power at low engine speeds, as this makes for confident yet relaxed driving, energetic acceleration, and long-range driving (up to 700 miles/1200 kilometers or more) on one tank of fuel. The E 320 BLUETEC definitely fulfills these requirements.
Moreover, its fuel economy ratings of 37 mpg (6.4 liters/100 km) in highway driving, and 26 mpg (9.0 liters/100 km) in the EPA city cycle, are higher than what many models in the compact class can offer. The BLUETEC system also performs well when matched up against hybrid technology, as the standard fuel economy ratings for the Mercedes E 320 BLUETEC are better than those for a hybrid of a comparable size and power output. The benefits offered by diesel engines often become more apparent in actual driving. That’s because diesel fuel consumption in real-life driving generally remains very close to fuel economy ratings, and is sometimes even better. This, however, is not the case with other drive systems. Diesels have in fact performed extremely well in comparative independent tests of diesel and hybrid vehicles conducted by journalists from automotive magazines on three different continents. In each case, whether driving straight across the U.S., Germany or Japan, the fuel consumption of diesel vehicles was significantly lower than that of hybrid cars.
The use of BLUETEC in the U.S. will be made possible by the introduction in that country of cleaner, low-sulfur diesel containing less than 15 ppm sulfur content. In line with corresponding legislation in the U.S. and Canada, the new fuel will become available all across the two countries in October 2006. The previous maximum sulfur content in diesel fuel was 500 ppm; sulfur content will therefore be reduced by a factor of 33, which will lead to an immediate noticeable reduction in emissions from all diesel vehicles. That’s because sulfur, which is present in varied concentrations in crude oil, is one of the key causes of particulate formation. Introduction of ULSD (Ultra Low Sulfur Diesel) has now made it possible to use particulate filters in the U.S. as well. What’s more, this fuel will enable efficient aftertreatment of nitrogen oxide emissions. The fuel supply for the world’s cleanest diesel has therefore now been secured, especially as the Mercedes E 320 BLUETEC’s ability to travel more than 700 miles (approx. 1,200 km) on one tank of fuel means its drivers won’t have to go looking for gas stations very often.
Rather than being an isolated solution, this is just one part of DaimlerChrysler’s overall strategy of ensuring sustainable mobility for the future. The 3.0-liter diesel engine in the E 320 BLUETEC is used by the Mercedes-Benz brand in ten of its model series. The BLUETEC technology will be initially launched in the U.S., after which Mercedes-Benz will prepare for its introduction to other markets. BLUETEC will also be made available in a passenger car model in Europe beginning in 2008. DaimlerChrysler does not plan to restrict the use of BLUETEC to the Mercedes-Benz brand alone: The Jeep Grand Cherokee BLUETEC concept car, for example, represents one additional application possibility for the future.
