Mercedes E350 BlueTEC with the new 9G-TRONIC

The Mercedes E350 BlueTEC

The Mercedes E350 BlueTEC is set to become one of the most fuel efficient six cylinder diesel models in its class,  the Saloon and Estate models now come fitted with the new 9G-TRONIC as standard. The 9G-TRONIC is suitable for rear-wheel and all-wheel drives as well as hybrid and plug-in hybrid drive systems and will be used in almost all model series and engines in the coming years. The E 350 BlueTEC fitted with the 9G-TRONIC as standard is available to order as Saloon or Estate models with immediate effect and the benefits of the new automatic transmission are being passed on to customers at no extra cost.

The new models with 9G-TRONIC undercut their predecessors in terms of both consumption and CO2 emissions. The higher number of gears and the broader gear ratio spread help to increase drive comfort and enable a significant enhancement to be achieved in terms of converting engine power into traction. The reduced fuel consumption of the Mercedes E 350 BlueTEC with 9G-TRONIC has primarily been achieved as a result of the high level of efficiency of the transmission. As part of this, the broad ratio spread of 9.15 for gears one to nine enables a clearly perceptible reduction in engine speed and is a decisive factor behind the high level of energy efficiency and ride comfort. Shortened shift and reaction times ensure optimum spontaneity combined with outstanding ease of shifting. In manual mode and the S programme in particular, the 9G-TRONIC responds significantly more spontaneously and enhances driving pleasure.

As previously reported, numerous other manufacturers are looking to additional gear ratios to achieve further savings in fuel consumption.  Technology experts ZF has already announced a nine-speed automatic, which will debut in the Range Rover Evoque this year. Land Rover global brand director John Edwards said “we are extremely excited about the 9HP which has been tailored exactly to dovetail with the unique attributes of our vehicles. It will add another layer of performance, refinement and efficiency, further enhancing Land Rover’s world class abilities.”

The Range Rover Evoque with a nine-speed automatic gearbox will replace the existing six-speed unit across all-wheel-drive versions of the Evoque, and significant improvements in fuel economy and a corresponding reduction in CO2 emissions is the promise.

The nine speed automatic gearbox will also eventually feature in some Chrysler products, and Ford and General Motors have announced plans to develop new nine- and ten-speed automatic transmissions together.
