The Infiniti Q45 has always been a powerful car. The 90-93 models will smoke most of the little racer boys in their mustangs and such. I have a 1994 model which has 278HP. If you run across one on the highway, don't mess with it unless you have some power because these cars will set you back in the seat from 80mph and easily hit the speed limiter at 155mph. The speedo registers 160 just like the Z. The new Q45 will be offered with a special package in the fall that includes 400HP. That's right 400HP.
