Why is the manual so much slower then the auto.
on a SD4 it's 8,5sec compared to 10sec. Thats 20% slower.
How is the in gear acceleration 80km - 120km??

RE: Why is the manual so much slower then the auto.
I expect it's down to the number of gear-changes required to get there - probably 2 - which will be quicker in a decent automatic. I expect in-gear acceleration times will be the similar, though if you look at the information on gearings, the ratios are not the same. The same auto box is used in the SD4 and Si4 and the Si4 has a different final drive ratio to take account of the higher RPM and lower torque.

Evoque was great, now in an RRS SVR

Exactly!
Auto and manual gears have different FIRST gear ratio: manual has been configurated with the first gear very low (in order to move Off Road)

PS The only Evoque with "normal" first gear ratio is the eD4 2WD
