One of the highlights in the ongoing Frankfurt Motor Show is the Audi electric concept. The Audi Concept is called the A2 and it has all the elements of a roadster and racecar, fun car and city car. It has 480 kilograms allowing for seating for two individuals, with a sliding roof for entry that can remain open for sun while on the road.

According to the company, the technological innovations are geared for individuals who are interested in the technology and are interested about new designs appropriate for their age and status. The specific target market are those urbanites whose lifestyle reflects modernity as well as driving acumen.

The A2 concept car is made of carbon fiber reinforced polymer (CFRP) with the car’s driver cockpit is a CFRP monocoque with an aluminum structure. This full construction makes it ultra lightweight with a low curb weight of 480 kg. The wishbone suspension is a combination of CFRP and aluminum located with freestanding 21 inch wheels.

The car used cladding technology allowing 21 inch wheels are very light with a variant of the blade design from the Audi e-tron models. Overall, the car’s wheel measurements are 125/60 for the front wheels and 145/50 for the back wheels. The vehicle also uses pushrod technology, allowing for four disc brakes for more stopping power, similar to what is used in Formula One cars. As a result, the turning circle measures in at nine meters, which is deal for city streets. The steering does not need extra power because of the low weight of the vehicle.

For safety, there are crumple zones both at the front and rear areas with two airbags for a greater degree of passive safety. There is also an assistance system assisting the driver to avoid pedestrians and other road hazards.

The A2 car’s battery is mounted behind the seats and the 90 kg lithium-ion battery is able to store 7.1 kWh of electrical energy. The vehicle’s electric motors produce 15 kW of continuous power and 47 Nm of torque. The motors have single speed transmission and mounted behind the rear wheels. The vehicle can accelerate from 0 to 100 km/h in 16.9 seconds and is able to reach 60 km/h in six seconds. The driving range is about 45 miles and a full recharge can be obtained in 20 minutes using a 400 volt three phase current and an hour with a 230-volt household current.

Audi has also introduced Audi Wireless Charging (AWC). This new concept allows for contactless induction charging, which uses a coil and an inverter (AC/AC converter). When the vehicle is placed in a parking lot with a special plate connected to the power grid, the 3.6 kW primary coil set on the plate generates a high-frequency alternating field thus charging the car’s battery through an alternating magnetic field that induces an alternating current across the air gap in the secondary coil in the vehicle. Only when the vehicle is directly over the plate can the process occur and the coils are specific to one another.

The 64th International Motor Show to be held in Frankfurt, Germany would have a new line-up of new cars to offer the discerning car lover. The centerpieces used to be the latest in turbo charging as well as cam heads, now it it is batteries and electric motors.

In the latest holding of the show, BMW would unveil its i3 concept car. Volkswagen would also introduce its electric compact version, the UPI and the single seater Nils. The Audi would also showcase its Urban, their version of electric car as well as the A2 electric concept.

Overall, there would be eighty-nine new car models that would be unveiled in the motor show, from 1,007 participants ranging from cars to auto parts manufacturers. The theme of this year’s show is “Future comes as standard”. This in itself highlights the importance and the increased presence of environmentally friendly electric cars.

Mercedes Benz does not want to be left behind and is introducing its high end F125 electric car together with its standard engine models such as the B Class Benz, the SLS AMG, the SLK 250 CDI and the SLK55 AMG.

For its part, Toyota would be introducing the new hybrid version of its popular Lexus GS450h model. Also in its line up are the Avensis, the Prius as well, as the Lexus 450h. From France’s Peugeot, the first diesel hybrid would be introduced in its 3008, Sport 908, the 508RXH. It would also unveil its HX1 plug-in model. Hyundai-Kia would introduce its first European line, the i40 hatchback and its electric car, the BlueOn.

For all the participants, new regulations have made the new cars in the show much more important. The U.S. has recently instituted new fuel efficiency standards that automakers need to comply in order to be allowed to sell in the world’s second largest car market; cars need to run at 35.5 mpg by 2016 and 54.5 mpg by 2025.

To be able to sell in the European market, the European Union has imposed stricter standards on gas emissions as well as new tax regulations on car sales. In addition, there is a greater push for smaller vehicles, mainly as a result of the global recession as buyers have lower budgets with lesser disposable incomes.

The show would run from September 13 to 25, 2011 at the Messegelände in Frankfurt, Germany.
