Sorry for the long delayed response. I was out of commission for a little while ... another December hospital surgical visit

and I missed this question.
From a standing start, the M45 easily gets to 60mph faster than both the 91Q and 95Q I used to have. Very strong acceleration! To get the best results (particularly if you are trying to beat another fast car), the VDC needs to be switched off. Else the launches seem a bit more tentative.
From 60mph to 120mph, the M45 still accelerates faster than either Q I had, But the differences are a bit less obvious - particularly when compared the 91Q (see caveat below).
Above 120mph, I cannot comment as I have not yet taken my M above that speed. My 91Q felt very stable at high speeds (driving 145mph for long distances was easy), but I never felt that comfortable in my 95Q, so the fastest I ever drove it was about 135mph.
Some day soon, I plan to drive to Los Angeles and find a quiet stretch of I-5 to see how the M45 feels at very high speeds.
(Caveat: I should add that I sold my 91 Q in 1998, so my memory on its performance is a bit rusty.)
