186 miles is low, I’m guessing that, as it’s a pretty quick car, the reading is based on past driving and test drives will be somewhat aggressive. As with any car if you’re going around a roads as quickly as possible and are accelerating hard as you enjoy the car then the efficiency is pretty poor.
The current stats for the AWD suggest it doesn’t lose much range but everything else suggest you should see about 10-15 miles less than the RWD version.
