E200 Natural Gas Drive model introduced

Mercedes-Benz has announced a series of updates for the recently facelifted E-Class, including the adoption of a nine-speed automatic transmission.

The rear-wheel drive E350 BlueTec is no longer available with the seven-speed 7G-Tronic automatic transmission as this has been replaced by a newly developed 9G-Tronic nine-speed 'box. Despite the change, 0-62 mph (0-100 km/h) takes the same 6.6 seconds as before so there aren't any improvements in terms of performance.

However, the two additional ratios and inclusion of stop/start function have improved fuel efficiency in the combined cycle from 51.4 mpg UK (42.8 mpg US or 5.5 liters /100 km) to 53.3 mpg UK (44.3 mpg US or 5.3 liters / 100 km), while CO2 emissions are down from 144 g/km to 138 g/km.

The E350 BlueTec equipped with 9G-Tronic will return 44.1 mpg UK (36.7 mpg US or 6.4 liters / 100 km) in the city, while the 7G-Tronic model achieved 40.9 mpg UK (34 mpg US or 6.9 liters / 100 km). On the highway, figures have remained the same at 60.1 mpg UK (50 mpg US or 4.7 liters / 100 km).

Aside from this change, Mercedes-Benz has removed the standard six-speed manual gearbox from the E220 BlueEfficiency Edition and replaced it with the aforementioned 7G-Tronic automatic transmission. As a result of this change, mpg numbers have increased from 60.1 mpg UK (50 mpg US or 4.7 liters / 100 km ) to 64.2 mpg UK (53.4 mpg US or 4.4 liters / 100 km), while CO2 emissions have been slashed from 132 g/km to 114 g/km. Thanks to these changes, the revised model is Euro 6 compliant.

The E-Class lineup will also include from now on an E200 NGD which is a natural-gas model powered by a 4-cylinder, 2.0-liter turbocharged engine taken from the B200 Natural Gas Drive. It outputs 154 bhp (115 kW) and 199 lb-ft (269 Nm) of torque which should be enough for a 0-62 mph (0-100 km/h) time in 10.4 seconds. Mercedes-Benz says it has a combined cycle economy of 4.3 kg / 62 miles (100 km) which transformed into mpg represents 44.8 mpg UK (37.3 mpg US or 6.3 liters / 100 km).

Wow, awesome mpg! With all these high mpg cars coming out it will be hard to sell my old 16 mpg car! But it will be with it on my pocketbook.

I already don't like the eight speed I have, in slow traffic my car either just wants to sit still or take off so it's a bit jerky.

have never driven a 8-speed 5 series. would not have expected it to be jerky in that Kind of vehicle. would be interesting to know if the 5 series is less jerky with other gearboxes. i have not driven many 8 Speed but the aisin in the Audi a8 is silky smooth. i assume the 5 series has a zf gearbox

It is smooth, very smooth it's only jerky at slow speeds in heavy traffic doing between 5 and 10 mph.

When will this end ?there must come a point in time where the weight and cost of the extra gears exceeds the benefits of comfort and economy. how often does that thing changes gears?

Trucks can have up to 30-speed transmissions...the sky is the limit and even then perhaps the outer rim of the known universe...

Hmmmmm...surprised they did not announce this new transmission as debuting on the new S class, and then a few days later made available on the E...strange.

i agree with, u rather strange. maybe they are introducing the 9 speed with the 6 cylinders only. my guess is that it will be introduced with the new yet-to-debut S350

Mercedes rarely or never introduces a new body at the same time as a new engine/drivetrain.
