Makers show some radical concepts

The hottest place in Frankfurt was not on the show floor but at the Volkswagen Group event on the eve of the International Motor Show.

One of the funkiest vehicles unveiled was Audi's urban concept electric vehicle. The urban concept defies description as it is modern but classic-looking at the same time, reminiscent of the 1930s Auto Union racing cars. According to Audi, those old vehicles were ahead of their time, as they were very lightweight with their engines mounted in the rear. In addition, the large, open wheels stood out from the chassis, just like in the new urban concept, which weighs just 480 kilograms.

The one-plus-one urban concept is not based on any previous model.

The funky concept features free-standing 21-inch wheels with blinking LED lights and is a new design language, the automaker says. The oneplus-one seating arrangement is slightly staggered and at a sporty, low level, says Audi.

The urban concept is powered by two powerful e-tron electric motors, which together produce 15 kilowatts of continuous power. The motors are mounted between the rear wheels, which are driven by a single-speed transmission. A lithium ion battery, which stores 7.1 kWh of usable energy, is mounted behind the seats.

Audi's second electrified ride unveiling was the A2 concept.

Weighing just 1,150 kg, the A2 features a lot of space for such a small car. The fourseater measures just 3,800 millimetres long. Inside, the centre console is attached to the driver's seat, while the rear console stretches forward between the two rear seats. Audi says there's even room between the rear seats for a bicycle.

The dash panel has a light, clean look and intuitive controls. The driver manages the many features via touch-control areas on the inside of the steering wheel. .

The exterior of the A2 concept features headlights heralding the next phase in LED technology, Audi says, known as matrix beam. A package of LEDs and micro reflectors generate a high-resolution and non-glaring high-beam light. Intelligent tail lights adapt their illumination to the conditions.

The A2 concept is a purely electric vehicle powered by a lithium ion battery. The electric motor is mounted transversely in the front of the car.

Audi unveiled several other world premieres, including the RS5, the S6, S6 Avant, S7 Sportback and S8.

The new RS5 features a high-revving V8 that Audi says is closely related to the V10 powering the R8. The 4.2 FSI delivers 450 hp and peak torque of 317 lb-ft. The Coupé launches to 100 km/h in just 4.6 seconds. Audi says it will increase the electronically governed top speed from 250 to 280 km/h upon request.
