Try keeping it in sport mode. I found this to be universally better than ordinary drive mode in the D4 and now in the sport. The slowness off the mark seems to be programmed and is extremely annoying when trying to keep an even pace with slow traffic especially when you want just a bit more and instead of that you "wake the beast". Sport mode seems to give a more natural response to the throttle. I only ever leave it in "Drive" when cruising. When I first started doing this I thought I was going to have a big hit on economy, I've found it to be negligible and if anything, better.

Anyway give it a go and see if it works for you.

Regarding the discussion above on the TDV6 and SDV6 and the number of turbos fitted to the L494 RRS I found this online which may clarify:

"For MY 2014 & 2015.0 the TDV6 and SDV6 are mechanically the same engine with a double (sequential) turbo with different ECU programming. From MY 2015.5 the TDV6 only has a single turbo, but with a more aggressive & efficient ECU programming so the power and torque remain the same with less fuel consumption. The SDV6 (still double turbo) has received new ECU tuning which has increased the power and torque."

This may explain the confusion.

The low pressure EGR system was fitted on the TDV6 at the same time as going to the single turbo.
