Test drive both the gle400 and gle450 same engine but different tuning. The 450 has a sport plus mode that really revs the engine and practically performs like my ml550. Likely rentech or something?

Well - no - the 450 engine performance was "blueprinted"/engineered by AMG - and I understand that initial engine production this year was assembled at Afalterbach as well - in January engine production will move to MB factory - so I have been told - so it's AMG's engineering/blueprint work that makes the difference - which of course includes the engine and tranny mapping as part - and different exhaust..

The GLE400 gives the GLE "backbone" as compared to the 350 V6 - the 450 engine is so sweet - whther GLE450 coupe or C450 sedan... very sweet...
