I haven't seen any test figures, and some road tests have questioned whether 4.5 secs to 60 mph (or even 100 kph) is achievable.
I've driven the car and would agree that 4.5 secs is a bit optimistic. However, the car feels FAST and torquey and is not lacking in performance in any way that I could observe. I drive an Aero 8 Series 3 as my other Morgan, so feel in a fair place to judge.
The gearing / fast and easy gearchange / clutch combination is great and will allow fast getaways.
The feeling is definitely right!
