Late last week Audi released some teaser sketches of its A2 concept car due at the 2011 Frankfurt Auto show, now less than a week away.Due to be positioned between the A1 minicar and upcoming Audi A3 Sedan compact car, the new A2 is spiritual successor to the original A2, an aluminum-bodied, ultra-efficient subcompact that went on sale in Europe in 1999.the early information and sketches didn’t reveal many details about the A2 Concept but we now know it also uses aluminum construction, and carbon fiber elements too. this helps keep the weight quite low, at 2,535 pounds. That’s more than the original A2 but certainly light by electric car standards. That aluminum body is a svelte 12.47 feet long, 5.54 feet wide and 4.89 feet high, but Audi promises impressive interior space.the electric drivetrain uses a 114 horsepower, 119 pound-feet of torque electric motor, with power going to the front wheels. Performance is brisk at 9.3 seconds to 60 mph, and top speed is limited to 93 mph.a lithium-ion battery under the floor gives enough charge for 124 miles of range, and can be charged in as little as 1.5 hours using a custom 400 volt charger. Recharging from a regular wall outlet takes 4 hours.
The A2 concept will showcase Audi’s new dynamic lighting technology too, known as matrix beam lighting. It uses microreflectors to direct a high resolution and low-glare light pattern onto the road. LED lighting also runs the length of the body and permeates through into the interior.High-tech rear lighting adapts its illumination depending on visibility and weather conditions, and a laser light unit at the rear can even project a warning triangle onto the road behind the car.the interior itself is stark and modern as you’d expect from a concept car. It uses a flat floor to give a feeling of space despite the small body size, four individual seats and a center console attached to the driver’s seat.the Audi A2 Concept will join Audi’s other take on an urban electric car at Frankfurt, the sporty Audi Urban Concept.the 2011 Frankfurt Auto show begins on Tuesday, September 13.
