My dad drove a '90 Q45 around when I was younger(very briefly). The acceleration feel was similar to the 4.2 liter M119.
However, I was quite dissapointed by how poorly it pulled downhill against a run-away Peterbilt playing chicken with us. My father hit the gas at 123 mph to get past this lunatic. It seemed to take forever to get near 140. I was very unimpressed.
