Audi on Wednesday delivered the much anticipated A1, aka Audi Metroproject Quattro. The A1 is intended to be a competitor to BMW's Mini Cooper series. It's envisioned as a hybrid-electric car with a 1.4-liter engine. It would be able to do zero to 60 mph in 7.8 seconds, have a top speed of 125 mph, and get about 48 mpg. The car could go up to about 60 miles on electric power alone.
