The new Mercedes Benz M-Class comes with the world’s only production seven-speed automatic transmission. When compared to the previous transmission generation, the seven-speed makes the SUV both faster and more economical while providing smooth, barely noticeable gearshifts.
Seven gear ratios provide a wider spread of ratios between first gear and top gear and, at the same time, allow smaller increases in engine speed as the vehicle accelerates through the gears. This gives the electronic control unit more flexibility in terms of maximizing fuel economy and making the transmission’s reaction time extremely fast. Unlike most transmissions, the seven-speed transmission will skip up to three gear ratios if necessary when it downshifts, shifting directly from seventh to fifth, for example, or even sixth to second. This helps the transmission choose the perfect gear ratio for quick acceleration and ensure smooth, almost imperceptible shifts in the process.
The new technology helps in faster driving and saving on fuel the most urgent requirement to save our planet.
