Then the SL7 RWD with staggered setup last much less, maybe not half, but considerably less than the AWD. something like 35K on rear and 45K on front on the RWD vs something like 60-70K on the AWD if.... you rotate every 10-15K, without rotation it will last 40,000 with extreme uneven wear. That's good, but I think not amazing, The Model Y should give much better when driving relaxed like you do. I get 15 kWh/100Km driving under 100mk/h on the IM5. and as low as 13 kwh/100km when under 90KM/h without hard acceleration. I suspect the SL7 800V will be more efficient for sure. the IM5 is very snappy when overtaking a car 100km/h you get to 130 on a blink without realizing it. but that doesnt affect the range really, I still get 15 kwh/100km even with occasional 130 over-taking. we overtake highway pickup trucks or large lorries at least 10 times per trip here... LOL, the love to drive like a snail in the right.
