The series of photos released by Acura Friday to tease its New York auto show debut on April 8 show a four-door car with a fastback design. It looks like a sports car, but could also be more of a crossover, as it is difficult to tell the height from the pictures. Rear headroom looks severely compromised from the sloping roof, especially if it is a sedan. We would expect it to get power from Acura's existing 2.4-liter four cylinder or 3.5-liter V-6 engine.
