Especially since the first C-Class, which is also available as an all-terrain (206)on the air suspension must do without, which it was in the series before (S205) still existed. This is a bit of a shame for the “small” All-Terrain, as it comes with real permanent all-wheel drive (power distribution 45 percent at the front, 55 percent at the rear), supplemented by a multi-plate lock – hardly anyone gets stuck with it that quickly.
The all-wheel drive of the A4 is not permanent
Audi relies on a multi-plate clutch supplied by Magna with fuel-saving shut-off of the entire drive train to the rear axle – with a quick reaction and without any functional disadvantage. This four wheel drive Audi also offers the not inconsiderable advantage that standard consumption with actually deactivated four wheel drive to be allowed to measure. However, the A4 allroad 40 TDI turns out to be exemplary on our fuel consumption test, making do with 6.1 liters diesel to 100 kilometers. The unladen weight, which is 195 kilograms lower than that of the Mercedes, should also play a role.

Seven-speed double clutch
The quickest way is to wake up the voice control with a “Hey, Mercedes” command and verbally express navigation destinations, radio station or temperature requests – we have never felt so understood by a car. The Audi works more slowly, often asking for confirmation clicks; he’s just older.
Mercedes relies on softer tuning
Both are comfortable; the Mercedes springs softer tuned, in comfort mode with a slight twist into the rocking. The Audi front axle is a bit more stubborn while still maintaining a high level of comfort. They don’t give much away when it comes to the steering either: Both respond linearly from the central position; the Benz seems to feel better in hand because of the more organic steering feel.
Diesel with different characters
Differences are evident in the driving culture. The Audi shakes when the start-stop system is on Traffic light fires again. The Mercedes diesel, supported by a 20 hp starter generator, starts up much smoother, but remains acoustically surprisingly present over the entire speed range. The noises of electric servomotors can also be heard constantly, especially from the rear. Which is probably because the body is so extremely quiet. Even at 200 km/h, almost no wind noise can be heard.
