Mercedes-Benz is once again ahead in the cog count game, having just debuted the 9G-TRONIC transmission featuring nine gear ratios. The 9G-TRONIC is currently only available in a single W212 E-Class facelift variant, the Mercedes-Benz E 350 BlueTEC.

The 9G-TRONIC transmission doesn’t do anything to improve the E 350 BlueTEC’s 3.0 litre turbodiesel’s ability to propel the car to 100 km/h – acceleration figures remain at 6.6 seconds. But the two extra ratios do improve the car’s fuel efficiency – combined fuel consumption has dropped by 0.2 litres per 100 km from 5.5 to 5.3 litres per 100 km, and CO2 emissions have been reduced from 144 to 138 g/km.

The new gearbox is only available on the rear-wheel drive version of the E 350 BlueTEC – the 4MATIC version soldiers on with the 7G-TRONIC for now.
