MINI has announced the three- and five-door
hatchbacks as well as the convertible will be offered with a new seven-speed
dual-clutch transmission.Designed to offer "impressive shift dynamics for
enhanced driving fun," the gearbox combines two partial transmissions into
a single housing.
As MINI explains, the "core element of the
system consists of two oil-cooled wet clutches: one of these is responsible for
the even transmission ratios (2, 4, 6) while the other is for the uneven ratios
(1, 3, 5, 7) and reverse." One of the clutches is always open and ready to
respond within just a fraction of a second.
The gearbox is always ready
to shift and this promises to make the car faster and smoother. The
transmission has also been designed with efficiency in mind so it supports the
engine start/stop system as well as the coasting function. The gearbox can also
access GPS data on properly equipped vehicles.
As part of the switch, models equipped with the new
transmission will be outfitted with a small electronic shifter that will always
return to its original position after selecting between drive, neutral, and
reverse. The shifter also has a park button and a Sport mode which can be
easily selected.
