Audi has already completed the first steps toward electric mobility. The next big step will be the hybrid variant of the Q5 with quattro drive system, which Audi will start production during 2011. Premium electric vehicle intended for the middle segment of the SUV has two drive systems that use the technique currently work efficiently in parallel: the combustion engine is a 2.0 TFSI engine that works in an intelligent and flexible in combination with a electric motor powered by a compact lithium-ion battery.
Audi can look back on the field of hybrid technology, thanks to its 20 years of experience. The first generation of the Audi Duo-concept car equipped with this technology and made from an Audi 100 Avant, was shown in 1989. In it, a five-cylinder petrol engine drives the front wheels while an electric motor 9 kW (12 hp), brought energy to the rear when the occasion demanded. As a storehouse of energy, the electric motor resorted to a Nickel-Cadmium batteries. Two years later, Audi developed a new duet version, this time on the basis of an Audi 100 Avant equipped with quattro drive system.
In 1997, Audi goes one step further and became the first European car manufacturer that manages to build a limited edition of a hybrid vehicle, this is a new development of the Audi Duo, prepared on the basis of an A4 Avant. To move is used this time to the 1.9 TDI 90 hp in the company of a water-cooled electric motor that develops 21 kW (29 hp) powered by a lead gel battery located in the rear of the vehicle. This time, both engines will use their power to move the front wheels.
In parallel with the hybrid technology, Audi is currently developing a family of electric cars that will be able to run for long distances. Electric cars are the e-Tron, among which also includes plug-in hybrid models. The basic idea is to offer a new type of dynamic driving pleasure according to a state of the art and clever ways. Although e-Tron models from Audi are still very young, and differ significantly in appearance.
The first e-Tron debuted in September 2009 at the IAA in Frankfurt, when they showed a prototype high performance sports car equipped with four electric motors (one at each wheel) that together offered a power of 313 hp. This two-seater accelerates from 0 to 100 km / h in 4.8 seconds and its top speed was electronically limited to 200 km / h.
In its lithium-ion batteries, the first e-Tron stored up to 53 kW / h, enough energy to circulate for approximately 250 kilometers. With the current high voltage, the battery can be recharged at a standard outlet in about 2.5 hours. The concept of the four engines and can act very precisely regulate individually the movement of each wheel at all times. This way of controlling the rotation of the wheel by “vectors” torque, is the beginning of a new more advanced stage of quattro drive system, the e-quattro.
At the Detroit Motor Show of 2010 appears another concept car with technology and “Tron. This time is a lightweight, compact two-seater equipped with two electric motors applied to the rear axle which generated a combined capacity of 150 kW (204 hp). The last to arrive at the family e-Tron has been a dynamic Spyder, the star of the recent Paris Motor Show. Its battery can also be charged from a conventional outlet has two electric motors applied to the front wheels with a power of 64 kW (87 hp), while behind the cabin is a twin-turbo 3.0 TDI engine that sends 300 hp and 650 Nm of torque to the rear wheels through the use of a transmission S-Tronic 7-speed.
The electric car Audi A1 e-Tron, unlike its predecessors, is specifically designed for driving in congested areas. Its electric motor delivers 45 kW (61 hp) operating in continuous mode, while its autonomy in electric mode is similar to that of e-Tron Spider, equivalent to about 50 km. A small rotary engine located at the rear allows you to increase the range recharging the battery and thereby dispelling any concerns the customer may have about the limitations of its scope. In its standard configuration, this model for the great city of Audi can cover distances up to 200 km.
In 2011, Audi will join three partners-the energy supplier E. ON, the utility of Munich and the Technical University of Munich, to develop a test fleet of A1 and-Tron before launch. This summer, the first vehicles will begin to circulate in the Bavarian capital while 200 new refueling stations located in the streets come into operation.
By 2012 the first Audi model with pure electric motor, a sports-Tron technology and high performance would be seen circulating around the roads in a limited edition. It will be built at Neckarsulm factory with extensive experience in producing sports cars certainly unique character.
The broad approach that seeks Audi covers all practical aspects of electrical conduction. It extends from the thermal load management and energy from the battery to the operating strategies of mechanical units, including quattro, braking and energy recovery processes. The principle of efficiency-what we understand as the careful handling of every ounce of energy, electric mobility brings new and exciting challenges for the automotive industry.
With this global approach, the brand with the four rings ensures that its core values will get even more evident even with the transition to electric mobility. Elegance, dynamism and efficiency, Audi will continue and expand its securities in the future.
Electric vehicle with lithium batteries do not emit CO2 or damage the environment if the electricity comes from renewables such as wind, solar photovoltaic and solar thermal or thermal. Wind turbines can supply electricity to electric vehicles in the future will also serve to store and regulate the electricity intermittent wind energy sector.
