When comparing the current engine variant build to a different engine during a facelift (in the current screenshot to the previous variant), the graph doesn’t show the previous variant’s power and torque graphs. Same with the efficiency/torque and efficiency/power graphs. I seem to remember that in previous versions both the current and comparison variant’s graphs were shown. The table on the left shows the correct specs though.
Indeed that is the case. I’m not sure if we get around to fixing this for the planned merge with the default branch or if it has to wait for 4.1. Thanks for pointing out!
