The base car in Canada has a normal ignition key -- just the upper trim car has the button.
So start/stop was an option, and I used it. (Engine-off coasting too, at times.)

Still, the CVT gets better fuel consumption ratings (marginally better) than the manual in the EU. I think I know why. The CVT lets the engine rev at insanely low revs as soon as possible. 100 km/h is 2000 revs. 50 km/h is 1100 revs. Apart from that, the CVT has lock up and will also at other loads and speeds choose maximum torque Always (unless sports mode or low gears are selected).
Torque / HP graph added to post #1. (Thanks, alex16)

Added another dyno graph to post #1.
It's from a Philippine spec Mirage.

That's at the wheels, I'm sure.

Detailed and accurate performance figures for both the 1.0 and 1.2 liter engine can be found on the austrian homepage:
Space Star MY 2015
I will update all driving performance diagrams for the three different motor versions.

I think they are controlling lift with the rocker system, but also cam timing through the much older system of advancing and retarding the cam timing.
Being able to do that INDEPENDENTLY means they can control the valve lift, which eliminates the need for throttling the air flow by restricting valve lift aka not more throttle plate restriction under certain conditions.
AND they can atkinsonize the engine by shifting overlap from before and after bdc-tdc, thus variable compression. Open the intake later in the induction stroke to reduce compression if necessary.
Low lift valves mean high swirl-turbulence aka potential stratification-lean burn- stuff we haven't even imagined.
Now I know why this motor can do what it does, like propell a vehicle 55 miles in 1 hour on one gallon of cheap pump gas.
