First BMW comes out with the first 6 Speed auto for public consumption in their New 7 series. Now Benz comes out with 7spd?? lol

Mercedes-Benz introduces world’s first seven-speed automatic transmission


Stuttgart, Germany - The world’s first seven-speed automatic transmission for passenger cars will be a standard feature of the E 500, S 430, S 500, CL 500 and SL 500 models beginning this Fall. It will replace the standard five-speed automatic transmissions.

Mercedes-Benz reports that the newly developed seven-speed automatic transmission reduces fuel consumption in the NEDC driving cycle by as much as 0.6 litres per 100 kilometres (depending on the car), increases acceleration from 0 to 100 km/h by up to 0.3 seconds, and allows significantly quicker intermediate sprints from 60 to 120 km/h. At the same time, shifting is smoother than with the current five-speed automatics.

Mercedes engineers have achieved these advances through the use of seven gear ratios. These allow the automatic transmission to retain the small increases in engine speed which are important in ensuring optimum gear ratios, whilst at the same time offering a larger ratio spread between the lowest and highest gear. This gives the electronic control unit more flexibility to adjust shifting in such as way as to keep fuel consumption low and the transmission’s reactions fast.

It also lowers the average engine speed – a clear plus point in terms of both cutting fuel consumption and keeping the lid on noise levels.

When the driver switches down rapidly through the gears (kickdown), the new transmission does not always select the individual gears in strict order. Instead, the 7G-TRONIC will miss out a particular gear if necessary, switching from seventh gear straight down to fifth, for example, and from there directly to third. In this situation, only two gear changes are actually required – instead of the normal four – in order to accelerate quickly using kickdown.

As in its predecessor, one feature of the new seven-speed automatic transmission is a lockup clutch in the hydrodynamic torque converter. In many situations, this system largely eliminates slip between the pump and turbine rotor. It does this by establishing a virtually fixed connection wherever possible between the engine shaft and transmission shaft, creating an extremely effective barrier to output loss. In contrast to conventional automatic transmissions, in which torque converter lockup is only possible in higher gears, the lockup clutch in the new seven-speed automatic transmission from Mercedes-Benz is active from the first gear up.

Despite these technical advances, the 7G-TRONIC automatic transmission is barely any larger or heavier than the five-speed automatic transmission currently fitted in Mercedes passenger cars. Credit for this achievement goes in particular to the transmission casing, which is constructed of lightweight magnesium – also a world premiere in volume production.

The new seven-speed automatic transmission will be produced at the Mercedes plant at Stuttgart-Untertürkheim, the original location of the company’s very first production facility. DaimlerChrysler has invested some 400 million euros at the plant in the construction of a new complex of buildings containing state-of-the-art production equipment and installations for around 1100 employees.

7 speed? i don't believe it. it's so unnecessary, 6 speeds are almost unnecessary. the only 7 speed that you need is for the new veyron, and because it can go over 250mph

probly for better accelatrion and gas saveage??

ehh. its got good technology behind it, but i agree that it isnt necessary over a 6speed. i think Ferrari F1 cars have 7speeds, cant remember

I don't believe it...


WTF is Canadien Driver.com I can make a site called DanielVictorhasabigcock.com and say BMW will give out car on a first come first serve basis..... ITS BS

Nicely written but FAKE.

I mean L337E46 has a 3 speed auto in his Daewoo Lanos. 7 is ridiculous....
On a six speed manual you barely get into 6th gear seven speed auto is useless.

I wonder if all automatics are eventually headed to CVT like AUDI. That's kind of like having an infinate number of gears. ANd that leads to more gas saveage. Hehehe :rofl

promote gas saveage and poor grammar
That right is. Sure be to goodly write and saveage on gas. Otherwise seaveage of gas bad be will, and suck grammer anyway. (why do I feel like Yoda all of a sudden?)
