C-Class: New 4MATIC generation for even better traction and driving stability
In the C-Class Mercedes-Benz is offering a new generation of all-wheel-drive
4MATIC, which improves on previous all-wheel technology with higher efficiency,
lower weight and more compact design. These advantages versus its predecessor
are reflected in even better traction and more efficient fuel consumption
of up to 0.5 litres per 100 kilometres. The 4MATIC models are equipped
with a seven-speed automatic gearbox as standard.
The newly developed
Mercedes-Benz 4MATIC is permanently active and therefore operates with
no reaction time, assisting the driver in unfavourable weather conditions
such as rain, ice or snow. This enables him to manage critical situations
with confidence. The centrepiece of the all-wheel system is a transfer
case with a centre differential, which is integrated into the seven-speed
automatic transmission. From here the drive torque is distributed to the
front and rear axles in a 45:55 split. At just 60 to 70 kilograms (depending
on the model), the permanent all-wheel-drive developed by Mercedes-Benz
is the lightest transmission system of its kind.
A newly developed multi-disc clutch on the centre differential transfers
the engine power to all the wheels with a basic locking force of 50 newton
metres between the front and rear axles, so that the new C-Class moves
off even better on slippery road surfaces and has even greater driving
stability than the preceding 4MATIC models.
As a standard feature Mercedes-Benz combines the permanent all-wheel-drive
with the ESP® Electronic Stability Program and the 4ETS traction system,
which selectively brakes wheels at the onset of wheelspin thus increasing
torque at the wheels with good traction. The system uses sensor signals
to measure out the automatic braking impulses, which improve traction
when driving on slippery surfaces and increase stability during critical
manoeuvres. In this way, 4ETS achieves the same effect as conventional
differential locks with appreciably greater comfort than other all-wheel-drive
cars.
Fuel consumption falls by up to 0.5 litres per 100 kilometres
High-torque six-cylinder engines are available for the 4MATIC models in
the C-Class. A diesel engine is also available for the first time. In
saloons Mercedes-Benz offers this permanent all-wheel-drive system in
the C 280, C 350 and C 320 CDI models; the C 320 CDI is available with
4MATIC as an estate.
With a 200 kW/272 hp six-cylinder engine the new C 350 4MATIC consumes
between 10.0 and 10.3 litres of premium petrol per 100 kilometres (combined
NEFC consumption), making it 0.3 litres more economical than its predecessor.
The C 280 4MATIC saves up to 0.5 litres of fuel per 100 kilometres. The
new C 320 CDI 4MATIC has an output of 165 kW/224 hp and the saloon version
consumes between 7.7 and 8.0 litres of fuel per 100 kilometres. Depending
on the motorization, this means that the all-wheel-drive system only increases
consumption from 0.2 to 0.4 litres per 100 kilometres.
The 4MATIC saloons offer the same, comprehensive safety and comfort features
as the rear-wheel-drive models. These include the AGILITY CONTROL package
with selective shock absorber control, as well as seven airbags, crash-responsive
head restraints, automatic climate control and alloy wheels. The 7G-TRONIC
seven-speed automatic transmission is also on board.
