I just drove a Passat V6 TDI 4Motion with 180 horsepower and a 6-speed transmission.
Nice thing

)))
100 was not possible due to the incline, but at 1000 meters altitude, it reaches approximately 57 km/h.
So, at a comfortable speed of 3000, we're traveling at 171 km/h.
The A6 V6 TDI with 150 horsepower and Multitronic transmission, which I occasionally drive, reaches 180 km/h at 3000 RPM.
My 1Z is already screaming at 4000

at 180.
