Finally took the e-tron out of the city and off to the Eastern Townships for a lovely weekend with Mrs Bp. The Audi settled at 5.1 l/100km indicated on gas after nearly 2 hours on the road, so the 1.4t is pretty frugal on the highway. Managed to burn the dealer gas from last spring down to the low-fuel warning to come on, and being out in the boonies I stopped at a fuel station with 90km left in range.
Apart from the top-up I did for the review, a bit over 2 litres IIRC, this was the first full fill-up. At 2,832 km on the odo.
Left this morning with a full battery, but range dropped fast as I turned on heat, seat heaters and rear defogger due to the 7 degree weather. Did not make it to work on e-power alone, but got closer than I expected, running on electric for about 23 km. Of course range will soon be going downhill as the cold comes in, but this will still be much cheaper to run than the TDI.
