Tesla cars have the best power efficiency, this has been validated many times. Tesla cars' motor drive is efficient top notch as well, that is the reason, when thorough assessment is done, one will find Tesla model Y has the highest score.Which model you driving? When I tested the new Y, the short ride of 5 pax only took 15.4kw/100km. That’s with some acceleration to test the pick up. Based on calculations, can hit above 428km. Maybe the new Y indeed has better efficiency as stated. Also do you use 1 pedal drive?
On Facebook, I see 2 groups of consumption experience. One group like you and the other group who said they can easily hit above 400km. Am guessing that aircon temp could be one difference.
I see posts that says that Xpeng can reach as low as 12kw/100km. But during the test drive, I clocked 19.5kw/100km. And that test drive I didn’t even drive very fast. Based on that, can only hit 338km. But yet on forums, many say they can exceed 400km. Others clock only 300 plus.
So without driving both for pro longed periods, I came to the conclusion that Tesla and Xpeng are both rather efficient, as compared to BYD. Would be happy to hear your experience.
Tesla model 3 /18" wheels can achieve 120-130 WH/km,
my performance model with 20 inches wheels can achieve 140-160, my daily drive/ slight aggressive profile is in the 150-160 WH/Km.
