I was looking through lap times of different production cars, and there are some wildly out of place cars doing ring laptimes, some cars are faster than they seem they should be, while others are slower than they should be. Which got me thinking how some cars truly get tested in showroom condition, and others get the “marketing” treatment to produce a laptime a showroom car would never touch, solely to sell more cars. Then I found this article that talks exactly about just that.

The point is that the nordshliefe test how the car breaks, turns (at different speeds), speeds up, at 95% which is what most street users will do. It penalizes cars that are very hard to drive and cars that are unstable over bumps and that’s very important to uses.
