Interesting replies. I was primarily asking this because it seems that by publishing this 'data' in a respected automotive magazine, the publishers are being somewhat irresponsible in downplaying the capabilities of the Tesla S brand compared to the Taycan, making it seem like there isn't really much difference in the range of the two cars, despite what Tesla claims. It seems like Car & Driver is claiming that if you took the S out on the highway, you could only really get less than 2/3 the mileage that Musk claims. Call me biased, but it just seems like more Tesla-bashing to me....
