Opel
RAK e Concept
The
Opel RAK e Concept opens a new chapter in electric mobility and extends Opel's
pioneering role in alternative propulsion systems. The radical RAK e is defined
by minimal energy costs, 100 kilometers for one euro, one third of the weight
of a modern small car, and a maximum speed of 120 km/h.
The
lightweight concept of the Opel RAK e is based on a steel space-frame structure
beneath a skin of conventional synthetic material. This allows a high level of
safety as well as affordable pricing. Opel deliberately avoids the use of
expensive composite materials in its lightweight-design philosophy, in order to
make electric mobility affordable for as many people as possible.
The
name "RAK e" recalls the pioneering spirit inspired by Fritz von Opel
and his revolutionary rocket-powered car in the last century. In 1928 RAK 2
catapulted the grandson of company-founder Adam Opel to a top speed of 228
km/h. The "e" not only stands for electric, but also takes up again
the idea of ground-breaking experimental vehicles.
The
potential of the spectacular experimental vehicle is reflected in the
innovative design. The bodywork is made of fully recyclable synthetic material;
the tandem two-seat passenger compartment is reminiscent of glider. Thanks to the
large cockpit canopy, the driver and passenger enjoy a feeling of spaciousness
and all-around visibility. The front seat, steering column and armrests
automatically tip forward to enable easy-entry; remote control via smart phone
enhances the optical effect of this action. The pedals and the steering wheel
adjust to the size of the driver.
The
sporty character of the two-seater is underlined by visible chassis components,
such as the wheel-integrated front disk brakes and the motorbike-derived rear
swing-arm. The rear wheels enhance agility with a tread width of only 600 mm.
The
development objectives - dynamic performance, low mass and optimum efficiency
coupled with maximum simplicity - are reflected in the appearance. Young,
environmentally conscious, or technology-fans, the Opel RAK e appeals to a
variety of customers for whom the cool looks of an electric vehicle are as
important as its energy consumption.
Around
three meters long and 119 cm high, the aerodynamic Opel RAK e offers
zero-emission driving at minimal running costs. After charging the battery for
three hours at a cost of about one euro, the experimental vehicle has a range
of up to 100 km. This results from the combination of low weight, minimal
frontal area, low rolling resistance, and highly efficient electric propulsion.
Energy
consumption per person is ten times lower than that of an economical small car.
The cockpit features displays showing battery state-of-charge or the nearest
charging station, infotainment equipment, and heating and cooling.
A
wide range of options in a variety of colors, materials and shapes would enable
a customer to personalize the Opel RAK e to his or her own tastes. Eye-catching
paint, contrasting starkly with the roof, and futuristic LED lights, are aimed squarely
at young buyers, "a customer-group for whom we have more new ideas than
ever before", says Mark Adams. Subject to local laws, even 16-year-olds
could begin their driving careers in the Opel RAK e, by limiting the top speed
to 45 km/h.
Weighing
only 380 kg the Opel RAK e is only one third of the weight of a modern small
car. The turning circle of just 5.5 m makes the experimental vehicle ideal for
inner-city mobility. The projected top speed of 120 km/h and zero to 100 km/h
acceleration in less than 13 seconds demonstrate that Opel's philosophy for
urban mobility includes motorway-capability. It takes very little energy for
Opel RAK e to deliver such performance - peak power output is 36.5 kW/49 hp;
10.5 kW/14 hp is continuously available. The useable battery capacity of 5 kWh
enables a range of 100 km, which corresponds to fuel consumption of just 0.6
liters of gasoline. Over an annual 10,000 km the Opel RAK e's energy
consumption would therefore be a modest 525 kWh. This could be supplied by a
five square-meter, 500-Watt solar panel mounted on the roof of the garage.
