Some More Feedback - After driving Biturbo one month
Likes:
Power/Torque
Manly sound
Handling
Feeling of "Mercedes integrity" in how it is put together
Great driver seats (ventilated etc)
Dislikes:
Transmission (lazy shifts, too much torque pull-back/hesitation on shifts). Am not sold on the benefits of the plate clutch over the torque converter. I think given that this is a "normal" automatic, a torque converter would be better at getting the car going smoothly and allowing the turbos to spool up while the torque converter "slips".
Not as fast as I expected given the enormous torque.
Terrible ride on rough pavement. Seems like the suspension bushings and/or tire sidewalls are WAY too stiff. Roughest riding full size car I have had in years. Rides fine on smooth roads.
Has spent 1/3 of the first month at the dealership while they try (unsuccessfully so far) to diagnose a nasty vibration at highway speeds. Going back again as soon as they can get yet another set of tires. (The stiff ride I mention above may well be amplifying the vibration).
So, all-in-all, I am ambivolent about the car so far!
This is the original review I posted after having the car only a few hours (It has not improved with age/familiarity!).
Car history: E55, E63 Normally aspirated, Jaguar XFR - now E63 Turbo - 550 hp version. (Also have an SLS and a GT-R).
Picked up today.
I like it!
Engine feels quite strong, car is fast, although not scary fast. But faster and stronger than either the E55 or NA E63 (not surprising with 590 lb-ft of torque).
Car rides and handles well. Transmission still is too lethargic. Definitely could sharpen up the shifts, especially in manual mode. Quite good in automatic mode.
Feels like a strong luxury, comfortable car, which I am sure is AMG's objective.
I would have preferred a bit more of an edge to it, at least in Sport + mode - (the original E55 - the "monster" - had a bit of an edge in my opinion).
Anyhow, off to break it in !!
