Right, so some quick stats on the AH3 long-distance.
Very easy to get consumption to 8.3l/100, even doing crazy overtaking on the N2. Got it down to 7.1 for ±100km between George and Plett but can see it's capable of going at least 0.5 lower with conservative driving in Eco Pro - got to Plett in Comfort mode. The one issue with having it in Eco Pro is how lazy the accelerator pedal is - my foot/ankle started aching after a while and had to switch it to Comfort.
Daily-driving in town is significantly worse at 9.1-10l/100 but it's directly related to the landscape that I drive every day, which is up the M3 into the top of CPT CBD, so constantly climbing hills which is horrid for consumption in such a heavy & thirsty vehicle.
Anyone have comparisons with a stock 335i?
