I recently purchased a raven Model S that supposedly is rated at 373 miles of range by the EPA. In the real world, I struggle to get anywhere close to that with normal driving. I've more or less assumed that was normal until I read this week that the Porsche Taycan seemingly easily went 40+ miles over its EPA range of 201 miles. Now I'm not trying to compare here the ranges of these two cars as I'm aware the LR MS has a longer range regardless. I am just confused as to how the MS can be rated at 371 miles of range when its seemingly impossible to achieve with normal driving whereas the Taycan rated at 201 miles seems to easily hit that and in this case surpass it by 30%? If the EPA tests are supposedly standardized real-world simulations how can such a wide discrepancy appear?
