Mercedes Goes Green with BlueEFFICIENCY Engine

We’ve heard a lot about luxury motor vehicles trying to change their worn out images. Personally I feel like I’ve been writing more than I would like about luxury cars saving gas, and while the gas saving gesture is nice, we should be able to expect more from a company with the resources to do more for the world.

Idealism aside, the BlueEFFICIENCY technology at least green in nature. The four-cylinder 200 horsepower diesel engine keeps the performance integrity of a Mercedes vehicle with a 45 mile-per-gallon economy. I do not drive a Mercedes, probably never will, but I do feel that 0-60 in 7 seconds is respectable for a car that is meant to save gas (most Prius driver’s brag that their car will hit 60 in under ten seconds). The cars eco-rating is awfully high. It complies with the European Union’s current emissions standards and is expected to meet the next revision of standards as well. The engine is presently being equipped to its latest C250 model.

Mercedes also funneled some fuel saving techniques into the design of the vehicle. The C250 comes equipped with tires that will reduce rolling resistance by 10% as well as rearview mirrors designed to minimize drag. The underside of the car is also smooth to reduce wind resistance from the underside. To further hold the integrity of the Mercedes name, the C250 is only available with a 6-speed transmission. To make that choice even more eco-friendly, the onboard computer will help change gears to maximize fuel efficiency (generally manual transmission cars are more fuel-efficient than automatics anyway).

Final thoughts. The engine which is being shipped in a limited number of C250’s (there are 5000 to be exact) is supposed to be making its way into other Mercedes-Benz vehicles. The four-cylinder engine is small enough and powerful enough to be used in some smaller Mercedes vehicles. Hopefully Mercedes will spread the love to the United States, but I haven’t heard anything about Mercedes intercontinental plans.

He became interested in the biofuel initiative after getting a job in the Raines Lab of Petroleum Alternatives at the university turning sugars into biofuels. He is the first to admit that he doesn't fully understand everything that he does or is trying to do, but enjoys doing his bit to help the environment. Anthony has very few plans for his future, but is interested in how natural systems work and how urban development changes these systems.
