I updated the first post with acceleration (and other performance) figures from Car & Driver for the US spec car. Interesting how they tested the CVT at 10.9 seconds to 60 mph, yet the UK spec car is 12.8 seconds.

Has anyone used one of these in their Mirage?

I was thinking further about this... I noticed when Motorweek tested the car at a drag strip here they recorded an 11.7 second 0-60 - again quicker than the UK figures. I notice though that they chirped the tyres off the line and that makes me wonder if they 'launched' the car (Stand on brakes, build engine revs up and when it reaches the stall speed of the torque converter and then go) to get a better result?
CVT has .55 to 1 highest ratio and 4 to 1 lowest, much greater spread than the manual. CVT also has taller final drive. Result 2kat 60 cvt 3k manual.
Their secret to efficiency at higher rpm is independently controlling cam open and closing points (but not duration).
ALSO independently controlling valve lift, where it can replace the throttle plate under most situations.
It also enhances DFCO coasting by reducing closed throttle pumping losses reducing engine braking.

Thanks - to clarify, what I meant by identical ratio spread was that the ratio spread is identical between the CVTs in all countries, rather than between the CVT and the manual - hence my wondering why the US testers have recorded 0-60 times between 1~2 seconds faster than the UK brochure quotes (12.8 seconds in the UK versus a measured 10.9 and 11.7 seconds in the USA). It's particularly interesting as the UK-spec cars are slightly more powerful and have slightly greater torque than the US ones.
Added to the acceleration stats from the Motorweek review.
It was for the CVT. Has anybody seen any stats for the North American spec 5-speed?
Added some Australian stats to post #1.
Note: while it's the revised 2016 model year, the car does not have the revised 1.2L engine with roller cam and 4+ HP.
