These differences are mostly noise. Tires with more/less wear, fully broken-in vs new cars, track surface temperatures (assuming its even the same venue) all make greater differences than these cars exhibit. Unless testing is much more controlled (same day, almost same time, same lane, same direction) or time differences are greater you're really discussing weather and condition differences.
Yep. My partner's son is a competitive skier. They both obsess over 100ths of a second differences on ski runs, and I try to tell them that snow, temperature, and wind conditions shift enough over a single event that winning by such margins is utterly meaningless. Winners are often determined more by what time of the day they make the run than by whether they're the better skier that day.
Actually, I think there are a lot of things that can make a driver much prefer one car's handling over another car's or make one car feel quicker or faster than another. But those things are seldom accurately predicted for a particular driver by tests such as the one here.
I've owned a lot of high-performance cars over the years: a Corvette, a Mercedes SL55 AMG, a MB/McLaren SLR, three Audi R8s (V8 coupe, V10 coupe, V10 spyder). Some of them were virtually identical in 0-60 times, in lateral g-force numbers, in slalom metrics,
etc. And in every discussion I've had with other drivers about every one of them, there were those who held the exact opposite of my views in comparing one to its competitors.
It's like buying seating furniture. You don't know which is right
for you until you sit in it a while.
