The best part about drafting a semi with your ACC on is that large rigs do their best to maintain a constant speed, when they do slow down or accelerate they do it gradually, and the they are a big target for the ACC to track. The downside is you can't see much road ahead, and trucks are prone to kicking up pebbles.If you're into (safely) drafting a large truck/bus you can dramatically extend your EV miles at high speeds. I got 70KM (43 miles) out of our 2012 that is rated for 55KM (34mi) a few days ago, and that was at around 120KPH/70MPH
If I do 120 km/h (75 mph) to cover 50 kms I would need 67 kms of range. I just did this the other day. Dropping down to 110km/h (68 mph) makes a big difference for me.Everyone in the carpool lane here does 70-75MPH, how many realistic EV miles could I get, assuming fair weather? What about assuming cold (40F) and rain?
