So after having the pleasure of owning a 2011 E90 M3 for a few years, I thought I would share my ownership experience to possibly help those considering buying one into the future.
Interior
Interior is typical of BMW’s clinical approach to interior design. High quality of materials used, and felt well put together. Never experienced any rattles per se. Not many clues that you are in an M car until you catch sight of the tachometer and speedometer - if you prefer your cars being understated then this is a plus. Has a nice solidity to the doors when closing when compared to the newer F30 series where the weight savings are evident and the doors “feel” lighter. It was easy enough to find a comfortable driving position but I felt that the seats could be more supportive in certain areas. The Novillo leather used is “soft” and while the soft leather does enhance the feel of the interior, I had to take special care to ensure the leather remained blemish free. I have seen many with worn/scuffed leather on the seat bolsters due to daily wear and tear.
Mine had the Harmon Kardon sound option fitted which offered decent sound quality.
Exterior
I personally like my cars with a subdued look (wolf in sheep’s clothing type) so the exterior styling of the sedan suited my needs perfectly. Combined with the 19” competition wheels, lowered ride height, bonnet power bulge, and the flared/hunkered/squat (for the lack of better descriptors) look of the rear fenders made the car stand-out. I always approached the car with admiring glances and often noticed others as well…there was just “something” that the car had that made even non-petrol heads take notice.
Performance
Have to start off by saying that this is one sweet motor. Sure there are cars with motors that make more power and torque using more displacement but this S54 is something special. If you love high revving motors then you will definitely appreciate and enjoy this. If not don’t consider an M3. There is much to appreciate regarding the engineering effort that allows this engine to remain crisp and balanced right through to maximum revs. Induction and engine noise is intoxicating and I never felt the need to upgrade the exhaust since the sound from up front was more than enough for me. The way the S65 makes it power at the upper end of the rpm range is extraordinary….it just seems to love chasing the redline and on its way there lighting up the red shift lights with aplomb. One characteristic which made the M special was on cold start and drive, the car would feel lumpy and almost constrained (sort of like holding the leash tight on a savage dog)…in a way begging for the engine oil to get up to operating temperature quickly so that you could explore the full range of rpms on offer….
The DCT gearbox is great and works extremely well in all situations (have never driven a Porsche PDK which seems to be the bench mark so can’t compare). Found myself often just downshifting to a lower gear to listen to the engine acoustics combined with the speed of the gear shift. Manual mode gives you full control and with traction fully off one additional shift speed setting. Thinking about it, I drove on manual mode probably 80% of the time. Launch control mode can definitely be improved (not sure if BMW has changed this with the new M3/4) - I think it is complicated (vs DSG) and only activates on a level surface. Even though the launch rpm can be adjusted down to 4000rpm, unless you are on a road/track with good surface traction you end up just burning out the rear rubber.
As an indication of comparable performance in a straight line, at the coast my brother in his Lumina SSV (headers with exhaust + intake + software) runs neck and neck repetitively with the M from a rolling start all the way to <200km/h. From a dead start the M walks away due to the dct gearbox and gearing. Note to prospective buyers, don’t expect to blow away hot hatches up at the reef. You may be disappointed and I have to say this (having owned/own turbocharged hatchbacks) that the performance gap to a lightly modified (software + decat) turbo car up at the reef at lower speeds (<120 km/h) is small. However, at higher speeds the V8 really gets going with it still feeling rock solid and stable on the road at 260km/h.
Regarding the torque of the S65, not going to say much except that I never had a problem with a lack of torque. I suppose that for me this wasn’t an issue since I always drove the car in the correct gear when looking to extract maximum performance.
Fuel wise, as an indication on the open road: trips to Durban (570km, around 4h45min incl. a stop for fuel etc. to give an idea of speed) would yield 10.4 l/100km down and about 11 l/100km up.
Handling
This is where I had the most fun and enjoyment with my car. Mine didn’t have m-dynamic so no intermediate traction setting to assist with controlling over-steer. ESP was either on or off. Needless to say the first time I switched it off and was too aggressive with the throttle ended with me facing the opposite direction in the blink of an eye. It is extremely easy to get the back end to break traction due to the sensitivity and response of the throttle. With experience though it gave me the most thrills and adrenalin rush to switch off the traction and due to the overall balance of the car be able to hold a power slide. Make no mistake though, with traction fully off this car can be a handful for drivers less experienced with rear wheel drive. In power mode, steering feel is nice and “meaty” and steering response is quick with more than sufficient steering feedback.
Ride comfort
My car had the competition package fitted as standard (yes, you do get sedans with the competition pack). With the adjustable dampers in comfort and with the 10mm lower ride height, ride comfort was acceptable and comparable stiffness wise to a Gti but would good bump absorption and compliance. Hardly ever used the sport setting on the EDC due to the condition of our roads but one could easily feel the difference switching between the modes. To my surprise, it also had sufficient ground clearance and I never had any issues with touching over speed humps or scraping on driveway entrances.
Reliability
Sold the car at a tick over 30000km. During this period I had no reliability concerns or issues with the car. It went in for its obligatory oil services, brake fluid change and a battery change since it wasn’t being used on a daily basis for a period. During my ownership, I did one oil top-up just to maintain full oil level. Car felt rock solid at all times and never once skipped a beat.
So that’s my story….have to say I was extremely sad to see it go but hopefully it will continue to provide enough thrills and an engaging drive for a long time into the future…
