Update after a holiday drive with family (1500km: Bangalore - Munnar[KL] - Tranquebar[TN] - Velankani[TN] - Bangalore):
I have completed about 3000KM which includes 50% of city driving in Bangalore and remaining 50% was clocked during the above holiday drive.
This is a terrific family car. Very practical for Indian driving conditions and super comfortable. Our plan was only to visit Munnar but the journey was comfortable enough for a family that hates road trips to sign-up for an extended trip.
I am not much of a driver to pass a judgement on this car but here is my take on how the car drove:
Drive experience:
Kickdown experience is a mixed-bag. If you are at lower speeds (20-30kmph I think) - the car jolts when it downshifts after kickdown most likely because it did not judge the downshift accurately, or it had to downshift 2/3 gears. Whatever it is, it is not smooth and it is a minor irritant given the car is so snobbishly composed all the time. Once the kickdown is successfully established - the engine growl is terrific. Some will like it, some will be surprised that their ultra silent cabin is intruded by this V6 growl.
Being a V6 petrol, the engine is super smooth and pulls effortlessly. On an unrelated note, I was surprised by many VW Polos that were driven quite aggressively during my highway runs. One Polo driver was particularly painful and he weaved through dangerously to overtake me in a tight situation forcing me to brake for his safety and give way to him (you know the type). When we got an empty patch, I tail-gated him at a safe distance forcing him to maintain the lead and he was able to sustain 180kmph for decent amount of time. I was impressed with Polo (not the driver though). Unfortunately I didn't notice which variant it is. I could have overtaken him at that speed as if it was stationary, with a V6 growl thrown in for the added effect. But this car makes me feel like a commercial pilot with precious passengers onboard.
Steering feedback and brakes are tuned more towards comfort. They do a decent job and give you the confidence and feeling of safety - but the fun-element is tuned out. The BMW F10 steering and brakes are super sharp and makes you grin each time you brake hard and upsets your passengers.
We were supposed to leave Bangalore early in order to reach Coimbatore before it gets dark. Due to some wrong planning we left Bangalore at 4pm and had to deal with plenty of rain and night driving before reaching Coimbatore at 10pm. The car was pretty good to drive in these conditions as well. No fogging up of the windows, decent road grip and visibility.
Features that I have come to appreciate:
It has got fantastic ground clearance. Compared to BMW F10, this makes such a huge difference because you can afford to be absent-minded about speed breakers and you don't have to come to a grinding halt at a speed breaker while all other cars that you just passed by don't feel sorry for you while they pass by

If there are a series of speed breakers, it can be really frustrating to go through the never-ending cycle of "bmw overtakes the auto" and "auto overtakes the bmw".
Next, it has a steering wheel layout where the horn pad stretches till the rim of the wheel. Now fellow Indian drivers, isn't that just a feature to die for? Unlike the other European cars where pressing the horn usually happens (or may not happen at all) after the 'event' and with a great deal of manipulation of your limbs - sound-OK-horn is a piece of cake with this car. Love it! The power of a loud horn - when you need it!
The seats are ventilated and very comfortable. The driver can adjust the front-passenger seat fully (position, memory, cooling/heating, etc.). It is great to pick up your family member from the airport and have the seat completely adjusted and cooled before he/she gets in - all this from the comfort of driver seat. Talking about the airport pickup/drop - the boot can be opened/closed from the driver seat.
It has got great suspension and coupled with good ground clearance, it offers excellent ride comfort. The car has seen all kinds of road conditions - narrow hill station roads, patched up village roads, road-diversions - never felt vulnerable and never had to drive with extra caution.
The keyless-go is also a huge convenience. Never have to use the key, very neat.
For a car in this segment, it is a comfortable 5-seater (relatively). Other brands completely eliminated the middle seat, or they have put seat adjustment and iDrive-ish controls on rear central arm-rest, as a result making space for the 5th passenger will make seat adjustments, idrive controls inaccessible. The mercedes central arm-rest only has massage and seat-contour controls which are OK to live without in case a 5th passenger has to accommodated.
The only negative when it comes to practicality is the need for parking space. As I drive it myself and will have to leave it unattended while parked - I can't take this car everywhere unless I know there is a decent parking facility. It has enough parking aids (sensors, camera, etc.) to help you park if there is space. I have parked it in shopping malls and office, etc. where the parking is a bit tight and you need to learn few tricks apart from being extra cautious. City driving is not a problem - think of it as a car as wide as Innova. And while on the move, length hardly matters unless you are taking a U-turn which needs planning. Overall the size is easy to live with and not as overwhelming as I thought it would be.
Interesting stuff:
Parkatronic - In other cars, the parking sensors turn off once you cross 20kmph or so. But in S (Mercedes in general), the sensors (only front) turn on every time the speed drops below 20kmph. I feel this is useful because you get alerted if some someone is cutting too close to your car in congested situations. It is calibrated to beep only during close calls, so it doesn't annoy you with constant beeping. I can turn it off, but never felt the need to. It has park-assist that I am yet to check out.
speed limiter - apart from the not very useful cruise control (in India), it has a speed limiter function. once set, you can't accelerate beyond the set speed. if you do a kick-down, the speed-limit is cancelled and it is business as usual so you are not restricted from performing any emergency overtaking maneuver.
transmission kickdown - the BMW transmission is far superior IMO. 7G transmission is not too bad, but it jolts on kickdown in certain situations. Basically, doesn't get it right all the time. Whereas BMW one seem to get it right all the time.
auto-hold - you press the brake pedal fully (or twice quickly) to keep the car on "hold" at traffic signals, etc. This is accomplished in other brands by pushing a dedicated button (AUTO-HOLD) on/off. Initially I thought the dedicated push button is more convenient, but after driving the S class for few days, I prefer the brake pedal technique - so much so that I end up pressing the brake pedal in bmw as well.
5-seater - This car is a decent 5-seater. For a family car, I feel this is a practical aspect compared to the other cars where middle seat is completely eliminated altogether.
intelligent light and high beam assist - i am yet to see *** they do. i tried using these features but never felt they worked either because our country roads *always* have on-coming traffic lights so the car never uses high-beam or they are not calibrated properly. I usually go for manual override for high-beam etc.
What could be better:
1. Transmission doesn't get it right few times (kickdown at low speeds, steep uphill climbs)
2. No dedicated button to reset all the AC zones to a single temperature (has to be done through COMMAND)
3. Not possible to engage reverse parking sensors/camera without putting the car in reverse. I prefer to switch on the parking aid at traffic signals to see if I am too close to trucks behind me, etc. Not possible to do it in S without engaging reverse.
4. AC blower sound. The car is so quiet that AC blower sound is pretty loud relatively.
5. BMW brakes are damn sharp. S never gave me that feeling.
6. No video through SD/USB card. Plays video only though DVD disks.
7. Engine bay is not properly sealed for dust I feel. BMW does a better job.
8. The regular floor mats I bought are too small :(
9. They should have given storage for DVD cases, etc. under front seat.
10. I am yet to find a comfortable position that is friendly to my ankle during busy stop-and-go traffic. Need to spend time to get the correct seating position for my right foot. I suspect A and B pedals have too much height difference - but need to experiment more.
11. Petrol price ;-) Gives 5-9 kmpl depending on the driving conditions.
Overall, I am happy with the purchase. Though I have not done a comparison shopping before buying, I feel this is much more practical, easy to live with and less-flamboyant car when compared to the competition.
So long.. till the next trip..
