Mercedes-Benz S 320 CDI
BlueEFFICIENCY: The most frugal S-Class ever
Stuttgart – From the end of 2008,
Mercedes-Benz will be adding to its range one of the most
fuel-efficient and therefore economical luxury saloons around in
the form of the new S 320 CDI BlueEFFICIENCY.
Effective detailed modifications
and advanced technology have lowered the fuel consumption and
CO2 emissions of the new model variant by some ten per cent
compared to its predecessor, which was itself very economical.
Features of the first BlueEFFICIENCY model in the S-Class range
include on-demand power steering, an automatic transmission with
standstill decoupling, as well as tyres with reduced rolling
resistance. All without compromising the high standards of
comfort, performance and driving pleasure in any way.
By bringing out the new S 320 CDI
BlueEFFICIENCY, Mercedes-Benz is carefully pursuing its strategy
for developing environmentally sound premium models that also
encompasses the S-Class. The latest variant of the luxury
saloon, which is due to supersede the S 320 CDImodel from the
end of this year, is more fuel-efficient and, as a result, even
more economical than its predecessor.
With fuel consumption of 7.6 litres per 100 km (a reduction of 0.7 litres) and CO2
emissions of 199 g/km (a reduction of 21 g), the S 320 CDI
BlueEFFICIENCY is set to achieve top marks in the luxury class.
Mercedes-Benz has achieved such exemplary economy by
incorporating a tailor-made BlueEFFICIENCY package. The
package’s key components:
The power steering’s hydraulic
pump that is driven by an electric motor has an on-demand
design, meaning that it only builds up pressure when the driver
actually turns the steering wheel. This has the effect of
reducing energy and fuel consumption when driving for long
distances in a straight line – such as on the motorway.
The 7G-TRONIC seven-speed
automatic transmission is equipped with standstill decoupling.
With this feature, the torque converter interrupts the power
flow as soon as the vehicle draws to a stop with the engine
running, in much the same way as the clutch on a manual
transmission. This eliminates the converter’s hydrodynamic
resistance, lessening the load on the engine and lowering fuel
consumption. Standstill decoupling has the added benefit of
reducing noise and vibration levels when stopped, and enables
even smoother idling. The slip-controlled clutch engages the
instant the driver releases the brake pedal, allowing the
vehicle to move off without the slightest delay.
The S 320 CDI BlueEFFICIENCY
rides as standard on 17-inch light-alloy wheels shod with
reduced rolling resistance tyres, featuring a special carcass
There has been no change in the V6
powerplant’s superlative output and torque figures of 173 kW/235
hp and 540 Nm respectively. Thus equipped, the S 320 CDI
BlueEFFICIENCY completes the sprint from 0 - 100 km/h in 7.8
seconds and attains a top speed of 250 km/h.
The luxury saloon with fuel
consumption and emission figures on a par with a medium-size car
can be recognised from the outside by the “BlueEFFICIENCY” badge
on the front wings. The S 320 CDI BlueEFFICIENCY sees
Mercedes-Benz further extend its line-up of models offering
enhanced fuel efficiency and environmental compatibility.
The price for the S 320 CDI
BlueEFFICIENCY in Germany is unchanged at €70,864.50 (incl.
VAT). The long-wheelbase version costs €78,718.50 (incl. VAT).
