I picked up my new Berlin-built Model Y LR RWD in Glasgow on Friday and having done nearly 500 miles (mixed driving but quite a bit of motorway and A-Road) it’s averaging 309mWh/mi or roughly 3.3 miles per kWh whereas my old Model Y RWD with the 58kWh LFP battery averaged 243mWh/mi over 49,800 miles. With all-season tyres on. To hit it’s claimed range of 371 miles it needs to average 209mWh/mi so it’s miles out.
Im not entirely sure why I thought putting a 50% (bigger capacity and heavier) battery would give the same or better efficiency, but I did and I’m currently NOT very chuffed. I did 70 miles this morning with the heater off (12C outside temperature) and it got down to 260mWh/mi over the trip but I never broke 60mph the whole way and most of it I was following a Buffaload at 56mph so I would have expected 200mWh/mi rather than 260. Currently the crap efficiency is cushioned by the free supercharging but from the end of the first year I’ll be paying for my own electric so it needs to be closer to 250 than 300.
I may not have it dialled-in quite right - the settings are the same as my old RWD - Chill mode from collection, and Creep mode and it‘s 42PSI cold tyres. This is with the standard 19” Hankook tyres and I’m dreading putting my Goodyear Vector 4Seasons on later this week.
I‘m also quite surprised that the Berlin build quality isn’t as good as Shanghai - the panel gaps are bigger (I measured them) and the doors need a really hefty shove to close them but they have fixed the positioning of the seat-belts so they no longer cut into your neck. The software also seems to be slightly different between the two cars (Hardware 4 vs Hardware 3?)
Any suggestions on how to boost the efficiency?
