(from smart press
release) smart fortwo electric drive: The smart with electric
drive is coming to the USA and Canada
New York – Following the
successful launch in European cities the new smart fortwo electric
drive will take to the roads of North American cities from the
autumn. The electrically powered trendsetter has been rolling off
the production line since November 2009 – and due to the huge demand
the initial production volume has been increased from 1000 to 1500
vehicles. The second generation smart fortwo electric drive is
equipped with an innovative and highly efficient lithium-ion
battery. It is neatly accommodated between the axles, which means
that space is not compromised in any way in the intelligent
two-seater vehicle. A 30 kW electric motor is fitted at the rear.
This provides for very good acceleration and high agility with 120
Newton metres of torque that are immediately available. The smart
fortwo electric drive can be charged at any normal household socket.
The fully charged battery has sufficient power to cover
approximately 135 kilometres in accordance with the New European
Driving Cycle, making it ideal for urban use. smart has made
electric drive a practical alternative for mobility with zero local
emissions in urban areas. The first of the new smart fortwo electric
drive vehicles were handed over to customers in Berlin at the end of
2009, and the environmentally friendly pioneer will now demonstrate
its suitability for everyday use in further cities in Europe, North
America and Asia. From 2012 the smart fortwo electric drive will be
available to anyone interested in almost 40 smart markets.
Marc Langenbrinck,
responsible for brand management at smart says "In 1998 smart
revolutionised urban mobility with the unique smart fortwo vehicle
concept. Now smart is once again taking on a pioneering role and
redefining zero-emission urban mobility. We are the first
manufacturer to launch a series-produced electric vehicle. Daimler
is spearheading electric mobility with the smart fortwo electric
drive. The smart fortwo electric drive is a further logical step in
the evolution of the smart brand which boasts the fleet with the
lowest fuel consumption anyway."
Environmental
friendliness and state-of-the-art functionality have been defining
features of the smart fortwo ever since it was launched more than
ten years ago. Since then its innovative concept has combined
sustainable, forward-looking technologies with individual urban
mobility. With a length of just over two and a half metres the
extremely compact vehicle can also park perpendicular to the flow of
traffic. In addition, the space-saving and environmentally friendly
two-seater currently has the lowest fleet consumption and it brings
its occupants to their destination comfortably and safely. Its
design is fresh, youthful, modern and yet sophisticated and has made
it an automotive lifestyle icon which shows that mobility,
responsibility to the environment and joie de vivre are compatible
with one another. The smart fortwo has established a class of its
own.
smart fortwo electric drive offers
innovative driving fun
The new smart fortwo
electric drive, which started rolling off the production line in
November 2009, is a logical continuation of a very ambitious goal:
the production of a well-engineered, attractive city car that has no
local exhaust gas emissions i.e. a zero emission vehicle. In 2007
smart kicked off zero-emission motoring in London with its tough
city traffic conditions. Since then 100 smart fortwo electric drives
of the first generation have been in practical customer operation
there. The feedback from the UK capital has been very positive and
confirms the high degree of maturity of this vehicle concept.
In 2008 smart presented the second generation smart fortwo electric
drive, a more advanced electric drive with an innovative lithium-ion
battery. Lithium-ion technology has decisive advantages over other
types of batteries including better performance, shorter charging
times, a long life and high reliability. Marc Langenbrinck says "The
second generation smart fortwo electric drive is based on a
successful and accepted vehicle concept with character and inherent
environmentally friendly characteristics. Its innovative electric
battery drive makes it the perfect car for the city: it is agile,
economical and climate-friendly. Motoring with zero local emissions
in an urban environment has become a reality. This equates to
driving fun with no compromises."
Electric drive factored in from
the very first concept
The smart fortwo
electric drive is a smart fortwo that does not make any compromises
with regard to safety, agility, comfort and space. Electric drives
have been part of the smart concept right from the start. The later
integration of the components needed for electric drive was planned
at a very early stage. For example, there is space for the battery
in the underfloor between the axles where the tank is located in
other smart models. The electric drive module does not limit the
space available in the smart fortwo electric drive in any way; there
is just as much interior and luggage compartment space as in a smart
fortwo with a combustion engine.
Powerful drive
A 30 kW magneto-electric
motor is installed at the rear of the new smart fortwo electric
drive and reacts directly without delay. Powerful torque of 120
Newton metres is immediately available. This results in a surprising
amount of power when pulling away. The smart fortwo electric drive
accelerates from 0 - 60 km/h in 6.5 seconds – just as quickly as a
petrol model which it initially leaves behind it. After a year of
driving the first generation smart fortwo electric drive in everyday
conditions on British roads one of the participants in the
large-scale London trial said "You can beat anything at the lights".
The maximum speed of the smart fortwo electric drive has been
deliberately limited to 100 km/h, a suitable maximum speed for the
city.
Thanks to the power
characteristic of the electric motor, just one single fixed gear
ratio is required. There is no need for any gear changing – a major
advantage in dense city traffic. To reverse, the engine's direction
of rotation changes. "Fantastic and easy to drive. You just get in,
turn on and go" was how experienced users from London summed up the
smart fortwo electric drive.
The second generation
smart fortwo electric drive is powered by a lithium-ion battery
developed by Tesla Motors Inc. with electrical energy of 16.5 kWh.
It is simple to charge at any fused 220 Volt socket. A fully charged
battery is sufficient for up to 135 kilometres of driving fun (NEDC).
This range is more than enough for city traffic as studies have
shown that cars drive an average of 30 - 40 kilometres per day in
towns and cities. For this, the vehicle only needs to be charged for
three hours. At an average speed of 25 - 30 km/h that is normal in
city traffic the smart fortwo electric drive can drive for around
four to five hours continuously before it needs to be recharged.
Plugging the car in overnight will fully recharge the battery.

Electronics optimise the battery
status and power consumption
Special electronics
ensure that all is well with the battery. This battery management
system constantly monitors voltage, electricity and temperature. If
one of these parameters reaches a specified limit – for example when
driving up long hills at constant peak power (kickdown) – the
electronics reduce the power output. However, this is barely
noticeable and it rules out the risk of battery overload.
The electronics also
monitor the charging process and control the capacity display. The
vehicle's power electronics supply the vehicle's electrical system
with electric current from the battery via a DC/DC converter. In
addition, they also control the heating and air conditioning, for
example, to minimise the strain on the battery. Clever drivers can
air condition their smart fortwo electric drive
in advance as long as their vehicle is being charged at home – the
long-standing dream of stationary cooling becomes a reality! No
other car offers this comfortable option.
Extensive equipment
The new second
generation smart fortwo electric drive is based on the smart fortwo
coupé/cabrio with high quality equipment. As well as air
conditioning with automatic temperature control and pre-air
conditioning, the equipment includes smart radio 9, electric power
steering, electric windows, electrically adjustable and heated door
mirrors, a two-spoke leather steering wheel, leather gear knob and
12-spoke alloy wheels. In addition to the battery indicator, an
ammeter shows the consumption and the recuperated energy.
Furthermore, all new second generation smart fortwo electric drives
have green painted alloy wheels, green mirror caps, green contrast
components and a green tridion cell created with green adhesive
foil. The words "electric drive" on the rear and in the mirror
triangle also draw attention to the vehicle's special status.
Very low costs
There are also numerous
factors in different countries that make electric mobility
attractive for customers. Tax relief and other government subsidies
play an important role. For example, the state of Monaco offers tax
relief of up to €9,000 to electric car owners. Other countries have
also set up funding programmes for sustainable mobility. France
grants a "super environment incentive" of €5000 for every vehicle
emitting less than 60 grams of CO2 per kilometre. In Great Britain
there is a bonus of up to ₤5000 and in Belgium of €4540. In Denmark
such cars are exempt from the extremely high registration tax and
there are lots of further examples in Europe. In the USA there is a
federal tax benefit of up to $7500 plus additional benefits
depending on the state or city. China and Japan have announced
subsidies of €6,500 and €11,000 respectively.
The maintenance costs
are considerably lower than those of a smart with a combustion
engine as the battery, motor and other components of the electric
drive are maintenance-free.
smart fortwo electric drive in
major cities in Europe and the USA
Since the end of 2009
the second generation smart fortwo electric drive has been delivered
to selected customers. Leases are offered for a period of four years
and 60,000 kilometres. The first vehicles were handed over to
customers in December within the framework of the "e-mobility
Berlin" project. Here, in cooperation with the energy provider RWE
and with the support of the German government and the city of
Berlin, Daimler is creating ideal conditions for running
battery-driven vehicles with no local emissions. This includes
setting up a network of electricity charging stations that enable
intelligent communication between electric vehicles and the power
network so that the battery can be charged when electricity is
cheapest. But as mentioned, the smart fortwo electric drive can also
be charged at any household safety socket with a 16 amp fuse
(standard in Germany and other countries).
Further new generation
smart fortwo electric drive vehicles will take to the roads of
Hamburg, Paris, Rome, Milan, Pisa, London and the Midlands, Madrid,
Zurich, Portugal, Denmark, the Czech Republic, Austria, Belgium and
the Netherlands during the first half of 2010. In the autumn of 2010
the smart fortwo electric drive will then also be launched in cities
in the USA and Canada, and from 2011 in some Asian countries. There
is already a very lively demand for the smart fortwo electric drive,
and from 2012 it will be produced in large volumes as a normal part
of the smart range and sold via the smart dealer network. This third
generation will be fitted with a new lithium-ion battery which
Daimler is developing to production maturity in cooperation with
Evonik. The lithium-ion battery currently used comes from Tesla and
represents state-of-the-art technology. However, further progress is
anticipated. The main differences between the two batteries lie in
the structural design. The Tesla battery consists of lots of
cylinder-shaped cells. The Daimler battery will be made up of fewer
but larger plate units. This will first and foremost enable a
greater energy density to be achieved (with greater energy content
for a higher range) and an even longer life.
With the smart fortwo
electric drive the brand is underlining its pioneering role on the
road to attractive individual mobility with no local emissions in
cities and urban areas. Dr. Joachim Schmidt, Head of Sales and
Marketing at Mercedes-Benz Cars says "All in all we believe that the
outlook for electric mobility is good. Whilst our competitors are
still presenting electric show cars, smart brought production models
that are fully suitable for everyday use to the roads last year.
This once again demonstrates our technical expertise and
responsibility."
