All the horsepower in the world is useless – unless it can be quickly,

smoothly and efﬁ ciently transferred to the road. The BMW 135i Coupe’s

300 horsepower is put to work with eye-opening speed via the optional

7-speed Double Clutch Transmission (DCT). With this technology, ﬁ rst,

third, ﬁ fth and seventh gears are grouped in one structure; second,

fourth and sixth gears are grouped in the other. When upshifting or

down shifting, the system switches between the two structures, so that

while one gear is being disengaged, the next is already in position. Gear

changes are made within a few milliseconds and without loss of drive

power, for exhil arating acceleration. In automatic mode, the 135i’s fast,

precise selection of the most efﬁ cient gear helps reduce fuel consump-

tion, while the almost imperceptible change from one gear to the next

signiﬁ cantly enhances comfort. And if a hands-on approach to switching

gears is your preference, the steering wheel-mounted paddle shifters

enable you to simultaneously keep both hands on the wheel as you up-

or down-shift in manual mode without the use of a clutch.

In both automatic and manual mode, you can press the Sports button

for an even more dynamic gearshift response. Using the Sports button

also changes the

accelerator and engine response, allowing the engine

to rev higher

before the transmission changes to the next gear – a fea ture

that is

particularly thrilling in manual mode. Here, too, the trans mission

electronics provide added assistance, adjusting the engine speed to

match the selected gear when downshifting.

DOUBLE CLUTCH TRANSMISSION: INSTANTANEOUSLY

TRANSLATING POWER INTO PERFORMANCE.

The 7-speed Double Clutch

Trans mission divides the

seven forward gears into two

structures. When one gear is

reaching optimal rpm, the next

higher gear is positioned for a

split-second spring into action.
