the ZT190 gear ratios should be raised a bit, so it will do at least 62mph in 2nd. When you notice that in Autocar the 2.5 75 is 0.1 quicker to 60 than the ZT190, I know it means nothing on the road, it just doesn't look so good in print. I realiise the ZT190 has to change gear twice compared to once for the 75 for the 0-60 dash.
