The BMW 730d

[steaner]

The BMW 730d and BMW 740d are the first diesel passenger cars in the world with a maintenance-free, six-speed automatic transmission (ZF 6HP26 and ZF 6HP32, respectively).

Featuring a much larger overall transmission ratio, this new transmission is particularly beneficial when setting off and at high speeds. With the lowest gear being designed for even more traction and pulling force in the interest of maximum acceleration when setting off, the additional sixth gear keeps engine speeds and, accordingly, fuel consumption as well as noise to a minimum. And thanks to shift-by-wire, the driver can shift gears, like on all 7 Series, straight from the steering wheel. In the Steptronic mode you can enter gearshift instructions within fractions of a second and without taking your hands off the steering wheel, simply by pressing the paddles on the rim of the wheel.
