2008 Mercedes GL 420 CDi Bluetec:
First one out will be the Bluetec version of the GL 420. Revealed as a concept at the Detroit Auto Show, Mercedes is now testing the real car in cold weather conditions. The production GL 420 Bluetec will keep the same big grille as on the concept, but the wider fender flares and the 21 inch wheels are not planned for the production.
With the GL 420 Bluetec Mercedes shows that even large high-performance SUVs can offer economical fuel consumption and extremely low emissions.
With its powerful V8 diesel delivering 290 bhp and 700 Nm of torque, the GL 420s anticipated fuel efficiency is just 9.8 litres per 100 km ( 24 mpg ). Seen here on these spy photos from Sweden, the bigger grille is disguised with some duct tape.
2009 Mercedes ML-Class Bluetec:
The model will combine advanced hybrid technology with the brand's low-emission Bluetec diesel know-how. Likely to hit dealers in 2009, the 4x4 should emit less than 200g/km of CO2 and return 40mpg.
That puts it on a par with the latest C320 CDI.While there's no official confirmation yet, a senior source admitted: "It's a safe bet that our first move into hybrids will come with the M-Class, using a 3.2-litre V6 Bluetec diesel."By linking the two-mode hybrid system, developed with BMW and General Motors, Mercedes believes it can eclipse Lexus's trend-setting hybrid SUV, the RX400h.
The set-up uses an electric motor in the transmission to reduce weight, improve efficiency and absorb less power. BMW's M5 is also likely to get the green technology, while the Chevrolet Captiva and Vauxhall Antara are two of GM's candidates for the set-up.
