>>28455986>The standards and test procedures have changed basically everywhere since then.Wasn't the old Euro "NEDC" test procedure basically just simulating city driving in an extremely slow old shitbox?
Two thirds of the test cycle is made of a city driving simulation that's so slow (both in terms of speed and acceleration) you can complete it on a fucking bicycle if you're somewhat fit. It's then followed by a couple minutes of slightly faster driving and a slow acceleration to highway speed, at which point the test ends.
Aerodynamics and rolling resistance made little difference in the test, but they could strip the cars of things like side mirrors and roof rails, pump the tires well above recommended pressures, turn off AC, run economy modes nobody would ever be willing to use, etc. The allowed margin of error for measuring speed was also high enough that every test was probably driven slower than intended.
Somehow, the test was total garbage at actually simulating real driving.
It's no wonder almost every car is suddenly 20% to 30% less efficient when tested with newer procedures like the WLTP.
