The Chilean Sustainable Energy Agency (Agencia de Sostenibilidad Energetica) a few days ago presented the results of some tests driving 5000km around Chile with sensors attached and proper measurements taken.

One of the drives I found interesting.

They left their office (in a 2018 Nissan Leaf) at 621 metres altitude and drove up into the Andes to 2859m, an altitude gain of 2238m over 52.5km, an average gradient of +4.3%. The battery reduced from 97% to 43% in this time. On their return journey to the office, the battery increased from 43% to 47% over the same 52.5km (initially increased to 51% after the steep part of the descent, before reducing to 47% on the more gentle part of the descent).

On the ascent 2.5km/kWH was recorded. For the whole journey, including the ascent and descent, 5.4 km/KWH was recorded.

Averaging across many other drives to other places on other days, all of which were fairly flat with no other trips with mountains, they recorded 6km/kWH autopista, 6.6km/KWH urban.

Call that an average 6.3km/KWH and it means that in the mountainous trip starting and finishing at the same altitude they achieved 86% (5.4/6.3) of the range they got on the flat. On the ascent at the average gradient of +4.3% they achieved 40% (2.5/6.3) of the range they got on the flat.

1 mile = 1.609km.
