Audi Urban Sportback, Spyder Models Revealed: 2011 Frankfurt Auto Show
Ahead of a more official debut at the Frankfurt Auto Show tomorrow, Audi has revealed its new city car concept twins, the Audi Urban Sportback and the Audi Urban Spyder.
These 1+1 seaters put the driver ahead (and slightly to the left) of the passenger and as city cars (not to mention European ones) are powered by electricity. Two electric motors power the rear axle through a single speed transmission, giving roughly 20-hp and 35 lb-ft of torque. Energy is stores in a 200 lb lithium ion battery behind the rear seats, which can be charged completely in just one hour using a conventional household outlet or approximately 20 minutes with a special fast charger. Acceleration isn’t exactly brisk, despite some rather sporty looks from these two concepts, with a six second time to 37-mph and a 16.9 second time to 62 mph. Both Audi’s have a range of roughly 45 miles.
Allowing the cars to achieve many of their “performance” and range goals is an ultra light weight chassis, weighing a total of just 1,058 lbs thanks to a structure comprised of both aluminum and carbon fiber, with carbon fiber-reinforced polymer (CFRP) body panels.
At 126.72 inches the Urban concepts are about two and a half feet longer than a smart car. Despite it’s diminutive size, at each corner are some sizeably Donk 21-inch wheels with ultra-thin 125/60/21 tires up front and 145/50/21 tires in the rear.
