To summarize the test: (how real is WLTP?):
Notes:
- 10 EVs, two identical routes on separate days. Airco on 19-23 degrees
- run-out the batteries completely.
- Teslas, Ampera, I-pace drove 96 km extra motorway to compensate for their larger battery capacity.
- BMW i3, Engine 125kW, Batt: 33kWh, WLTP 225. TEST: 225 and 237 => 103% WLTP (14.8 kWh/100 km)
- Hyundai ioniq Engine 88kW, Batt: 28kWh, WLTP 204. TEST 199 and 224 => 104% WLTP (12.2 kWh/100 km)
- I-pace on 20" Engine 295kW, Batt 90kWh, WLTP 480 (or 470?) TEST: 307 and 319 => 65 % WLTP (27.5 kWh/100 km)
- KIA soul Engine 81kW, Batt: 30kWh, WLTP 185 TEST 214 and 222 => 118% WLTP (13.6 kWh/100 km)
- nissan leaf (2nd) Engine 110kW, Batt 40kWh, WLTP 285 TEST 235 and 220 => 80 % WLTP (16.3 kWh/100 km)
- opel amperaE Engine 150kW, Batt 60kWh, WLTP 380 TEST: 379 and 375 => 99 % WLTP (16.1 kWh/100 km)
- Renault zoe Engine 80kW, Batt 41kWh, WLTP 300 TEST: 273 and 295 => 95 % WLTP (14.6 kWh/100 km)
- tesla S (100D = AWD) Engine 319kW, Batt 100kWh, WLTP 460 TEST: 411 and 433 => 91% WLTP (20.6 kWh/100 km)
- tesla X 100D, Engine 319kW, Batt: 100kWh, WLTP 430 TEST 404 and 395 => 93 % WLTP (23.4 kWh/100 km)
- VW eGolf Engine 100kW, Batt 35,8kWh, WLTP 219 TEST 218 and 244 => 106% WLTP (12.4 kWh/100 km)
I-pace (65%), teslas (X: 91% and S: 93%), opel ampera (99%), renault zoe (95%) and Nissan (80%) were the only ones with real world consumption below WLTP, probably because of the "96 km extra motorway". Nissan and Renault did not have the extra 96 km motorway, so are also "unexplained" outliners.
Looking forward to the software update..
