AERO,I found a road test for the Aspire in the May,1994 CAR and DRIVER,p.157
*frontal area 21.1 sq ft
*curb weight 2131 lb
*63 Bhp
*top speed 93 mph
*22.6 mph/1,000 rpm ( 5th gear )
*observed fuel economy 27 mpg *
*C&D road warriors drive very 'spiritedly' and I suspect that the 27 mpg figure is VERY conservative.
PS what ever you do at the back,stay away from 28-degrees.At that angle,the separation point moves around from a wagon-back wake,to a fast-back wake.The buffeting is horrendous!
