Yep, from what I've heard, it's just tested from acceleration tests. 👍

Yep, only measures when you set-off. Vigorous weaving and sudden braking doesn't register. Nor do handbrake 360's and doughnuts... even in FWD-reverse-spin-mode. But all that aside, I hit .50G in back-to-back runs with the Countryman 👍
 
Yup, just on take off. Kinda usless really. This is not lateral g's of cornering force but rather longitudanal force of accerleration. I like the new test course but this was kinda funky in my opinion, that PD doesn't realize from every car magazine on the planet that this is what they measure for a cars limit of adhesion in a corner. Ever seen them mention something like that in Motor Trend. Gee let's see how many longitudinal g's a Miata pulls on take off LOL!!! Test course should have had a skid pad or at least have been wide enough to let you go around in circles to measure the max lateral g's during the test.
 
You hit peak G's on launch but I also like to take off softly (to register very little g's) up to around 100 km/h then stab the throttle and see how many G's various cars pull at 100 km/h rolling start.

Dead stock (including tyres) 1971 Dodge Challenger R/T can get me 0.68g's off the line and still able to get 0.41 at 100 km/h :)
 
I nearly freaked when I got to testing the x2011 4.14g after that I thought ouch
