With fuel consumption of just 3.3 litres per 100 kilometres (NEDC) and emissions of 88 grams of carbon dioxide per kilometre the new smart fortwo cdi is the most economical production car worldwide. A full tank of fuel costs around €38.00* and 33 litres of fuel will take the 33 kW/45 bhp two-door car approximately 1,000 kilometres – for example theoretically from central Berlin to the outskirts of Paris without refuelling. With an annual mileage of 15,000 kilometres drivers of a new smart fortwo cdi would only have to refuel 15 times a year. In other words: the smart fortwo cdi is the right small car at the right time.
This is amazing!

Press Release:
The smart engineers have improved the successful cdi engine from the
predecessor model and equipped it for the future. The power and torque have
each increased by ten percent, whilst the fuel consumption has decreased by
around 13 percent. In figures this means power of 33 kW/45 bhp and maximum
torque of 110 metres that is delivered between 2,000 and 2,500 rpm. The new
smart fortwo cdi thus offers a combination of agility, economy and
environmental compatibility that is unique in this class and that adds up to
all-round driving fun.

This is thanks to the world’s smallest direct-injection diesel engine – a
masterpiece of engine development – that boasts technology previously only
found in larger capacity engines, despite its extremely compact dimensions.
For example the latest generation common-rail direct injection which builds
up high injection pressure of up to 1,600 bar (previously: 1,350 bar) even
at low revs, and injects the fuel into the combustion chambers with newly
developed six-hole injectors, enabling an even more efficient combustion
process.

A turbo-charger, charge-air cooling, electrically controlled and cooled
exhaust gas recirculation, hydraulic compensation of valve clearance and a
state-of-the-art light alloy construction are further features that identify
the cdi engine as a high-tech package.

technology
The three-cylinder engine has also adopted two-phase fuel injection from the
CDI engines of its sister brand Mercedes-Benz. A few milliseconds before the
main injection a small quantity of diesel is injected into the combustion
chambers where it ignites and preheats the cylinders. This results in a
noticeably quieter combustion noise level than an engine without this pilot
injection. The electronic "brain" of the cdi engine – a high-performance
micro-computer that controls the whole engine-transmission system –
calculates how much fuel is needed and the interval at which pilot injection
and main injection take place.

The quick response of the cdi engine is first and foremost thanks to the
compact yet extremely effective turbocharger that is housed in the exhaust
manifold. Its compressor wheel has a diameter of just 31 millimetres, yet it
rotates at up to 290,000 rpm and builds up maximum charge pressure of
approximately 1,150 millibars. This gives the three-cylinder engine more air
to "breathe" and enables it to develop impressive torque: 85 metres are
available even from 1,500 rpm – more than three quarters of the maximum
torque.

This torque curve plays an important part in the fun behind the wheel that
drivers experience with every kilometre driven in a smart fortwo cdi. The

top speed of 135 km/h.
As before, the engines of the smart fortwo are fitted transversally in
space-saving mode in front of the rear axle and they are inclined at an
angle of 45 degrees towards the rear. The consistent use of lightweight
materials means that the diesel engine weighs in at just 86 kilograms. The
crankcase features a state-of-the-art diecast aluminium bedplate design and
the cylinder head and cylinder head cover are likewise made of aluminium.

Exhaust gas recirculation, catalytic converter and particle filter
as standard
as standard
The three-cylinder diesel engine controls emissions in two stages. The
high-tech common-rail injection and the extremely efficient combustion
process inside the engine provide for a low level of untreated emissions.
Depending on the driving situation and the engine load, up to 60 percent of
the previously cooled exhaust gas is returned to the combustion chambers
where it is combusted once again thus greatly reducing nitrogen oxide
emissions. The exhaust gas recirculation works with an electropneumatic
actuator which enables it to react quickly to changes. An oxidation
catalytic converter and an open diesel particle filter are responsible for
the aftertreatment of the exhaust gases. These are housed together with the
exhaust silencer in a stainless steel case.

Automated manual transmission with kick-down function
The three-cylinder diesel engine works with a newly developed automated
manual five-speed transmission which the driver operates by briefly tapping
the shift lever on the centre console. When briefly pushed forwards the
transmission shifts to the next highest gear. Gently pulling the shift lever
backwards is sufficient to shift down. Shift paddles on the steering wheel
are optionally available and come as standard in the pulse model line. An
automatic transmission mode is also available for all equipment variants.
This is a standard feature for the passion model.

The clutch is opened and closed by an electric motor which means that there
is no clutch pedal in the new smart fortwo cdi. To enable quick intermediate
spurts the smart engineers have developed a kick-down function that is
activated with the accelerator pedal. This enables the driver to
spontaneously change down by one or two gears and to make even better use of
the engine’s low-speed torque.

One of the safest cars in its class
It is not just the three-cylinder diesel engine that is unique feature in
this vehicle class; the new smart fortwo cdi also boasts other technical
innovations as standard. For example: the anti-lock braking system (ABS)
with electronic brake-force distribution, the electronic stability programme
(ESP®), brake assist, full-size airbags for driver and passenger, seat belts
with belt tensioners and belt-force limiters, safety seats with integral
seat belts and the sturdy tridion safety cell of which 50 percent consists
of high-strength steel alloys and that has proved itself in the toughest
crash tests.

The body is 195 millimetres and the wheelbase 55 millimetres longer than
that of the predecessor. This, together with the wider track (front: 7
millimetres; rear: 33 millimetres) greatly enhance the ride comfort and
spaciousness. The luggage compartment capacity has increased from 150 to 220
litres or even from 260 to 340 litres when loaded to the roof (in accordance
with the VDA measuring method). This means that six drinks crates fit into
the luggage compartment of the new smart fortwo. The level loading area and
the twin-section tailgate facilitate loading and unloading.

Hello, long time no see ! How is your work at Bosch ? What are you doing there by the way ?
The CG picture of the SL facelift at Winding Road website is quite good. You should go and have a look :
http://news.windingroad.com/body-stylesmarket-segment/convertibles/face-lifted-sl-caught-cold-weather-testing/#more-8948
Just that the designer Christa Lehmann either anticipated the hood wrongly thinking that the designers would do something like the C-Class or CL-Class with a bulging hood to protect pedestrians or was mislead by the camouflage in the spy picture. It will actually have two “muscles” coming out on the hood like the first generation SLK. The front bumper is also a bit wrong and the side vents will have one longer chrome bar instead of two little ones made of plastic.
Tschuess !

That’s pretty cool. Small is beautiful. I guess they have to be prepared for the future. The environmental politics is gaining more and more momentum, there will be a lot of pressure put on car makers to reduce carbon dioxide emissions — a brand like Ferrari has to adapt now or face being cut out of key markets, like the USA, in the future.
