Gone are the days of the loud, dirty diesel vehicle. Technology has come a long way since Mercedes-Benz revealed the original diesel engine more than 75 years ago.

In 1936, Mercedes-Benz introduced the 260D, a car that delivered robust performance and 30 percent better economy from a fuel that had never before powered a car: diesel. Along with the first turbo-diesel in 1977, and the breakthrough of direct injection in 1997, Mercedes-Benz continues to reinvent this alternative fuel vehicle to offer higher torque and efficiency with up to 30 percent lower greenhouse-gas emissions than gasoline.

The technology under the hood is called BlueTEC, making Mercedes-Benz’s diesels some of the world's most advanced and cleanest.  And it's not just clean for a diesel – BlueTEC is one of the cleanest automotive options on Earth.

How does BlueTEC work?

BlueTEC is a system of advanced technologies working together to optimize combustion, minimize untreated emissions, and then treat what remains before it leaves the tailpipe. BlueTEC controls diesel engine emissions by driving exhaust gases through filters to the catalytic converter, where they mix with a new water-based solution called AdBlue. This process converts polluting nitrogen oxides into harmless nitrogen and water. The result is a significant reduction in soot and pollutants, making a BlueTEC engine robust, smoother, quieter and much more efficient than its predecessors.

A new generation

Mercedes-Benz didn’t stop at diesel. The company also developed BlueEFFICIENCY technologies. These include direct-injection gasoline engines which operate with microscopic precision and millisecond-quick response. The result is stronger performance from less fuel with fewer emissions.

Mercedes-Benz offers 5 different BlueTEC models and more than 20 BlueEFFICIENCY vehicles throughout the US. Each model combines efficient engines with lightweight design, improved aerodynamics and technologies for intelligent energy management. That’s blue-sky thinking for a better world today and tomorrow.
