BMW X3 M40i: Maintenance and ownership report after 1.5 years and 32,000 km

The SUV has the most tunable engine BMW has ever produced. With minor updates, power output can be increased to 650 BHP.

20,000 Miles (32,000 Kms) Regular service @ 19 months of ownership

Blau Rakete has served me well over the past 19 months that I have owned this amazing performance SUV. I was fast approaching 20,000 miles so decided to schedule a service with BMW.

Since everyone is busy and long-awaited for appointments, I got one that was earlier than my scheduled completion of 20,000 miles. I was 19,600 miles away but confirmed the appointment as the next date was far away and I also had no loan option.

I dropped the car off at 9:00 am with the following requests to Chris (My Service Advisor)

  • Multi-point control of the whole car
  • Check tire depth of all tires as I reached 20,000 miles on my stock Pirelli run flats
  • Engine oil and filter change
  • Fill all fluids in the car

I received feedback that my inside rear tires were wearing faster so an alignment was recommended and was quoted $250 as this is not covered by BMW Care. I declined as I would be changing the tires soon and would have them all balanced and aligned at that time.

I also asked them to clean the brake pads as I felt the bite was not as strong as when new. They don’t normally remove the pads and clean, but Chris made an exception.

Within 15 minutes we were done and he handed over a 2021 BMW X3 30e (hybrid car) with a comment “normally we don’t do loans for regular service when cars are returned the same day”.

Well, I told him “Trading what is not regular, that’s my job”.

I picked up the loaner vehicle and drove to another car dealership where I had an appointment at 10:00.

More details on this exciting 10 hour rendezvous can be found here.

Prior to this I enjoyed an overnight experience of this.

20,000 km property update

As some of you know I have a long history of owning cars and motorcycles and many of them are shared here on the forum as ownership threads. One of the biggest concerns (more than me, it’s for my family) is that I lose interest in my mount after generally 3 years or sometimes even before. Besides this problem, I have never owned a used vehicle in my life. As you can imagine, it makes no financial sense not only to buy new, but also to change the car as early as 3 years old, passing on the benefit of depreciation to the next owner.

Heck, I’m like that who rarely uses his brain and rides his emotions/feelings/heart.

I think this car has changed that mindset and style of ownership as I don’t plan on selling this car for the next 5 years. Every mile of the last 20,000 miles has been the best riding experience of my life.

I look for excuses to drive the car like:

  • Buy unnecessary groceries just because I want to take the car out for a spin
  • Always take the long way
  • Plan trips every weekend (because I don’t drive much on weekdays)

In a nutshell, Blau Rakete has brought me smiles that are equal to all the smiles put together from all of my car so far in this short period of time.

Driving, performance and engine

It’s a ridiculously fast car and almost looks like a sports car in the guise of a compact SUV.

Of the 4 modes – Eco Pro, Comfort, Sport, Sports Plus below, I’m roughly guessing the percentage of time the Blau Rakete has spent in the last 20,000 kilometres.

  • Eco-Pro: 30%
  • Comfort: 40%
  • Sports: 20%
  • Sports +: 10%

Eco Pro is the most relaxing way to drive, and the car is quiet and passengers can enjoy peace and driving becomes more comfortable. My mum has been visiting us for 6 months and she loves to sit in the front seat. At first she was afraid of the loud noise of the B58 every time I accelerated, so I always drive in Eco Pro when she is on board.

Comfort is the best of both worlds where you can enjoy the nice growl of the B58 engine, increased power and reduced squealing and squealing when braking.

Sport is where the real fun begins. Blau Rakete radically transforms into a deadly machine and it shows throughout the dynamics of the car. The suspension gets harsh, the steering feels nicely weighted, the engine growl increases, and every time you brake and slow down, the engine rattles and crackles make me smile.

Sports Plus is a mode I rarely use and only when I’m in the mood for aggressive, fast driving. To share a simple analogy, the car’s dynamics are double what I described in Sport mode. It feels like a tool meant to be on track and gives so much confidence when accelerating, braking and pushing through corners.

In this mode, even if you gently press the accelerator pedal and the car will hover at 90 mph or 100 mph. It’s impossible to get below 80mph in this mode and you feel like you haven’t even scratched the surface.

There aren’t enough words in the dictionary to praise the B58 BMW engine. It is by far the best engine that BMW has produced and extensively discussed and praised in several automotive forums.

The power is so relentless it feels like it will never end. Even at the top end, there’s absolutely no harshness (I’ve tried it several times on the mountains using paddle shifters and it hits the limiter and feels smooth as silk).

Of so many items in nature, this is by far my most favorite article on the B58 as it covers all aspects of this engine in easy to understand terms for an engineering noob like me.

I’ve read it so many times, I feel like now I’m ready to take an exam on B58. LOL!

It’s also the most tunable engine BMW has produced to date and with minor updates like the addition of a cold air intake, better exhaust system, etc. The B58 can be tuned to 650 hp at the wheel from its stock avatar.

Essentially for as little as $2000 it can be boosted up to a monster 650 HP (sure to come in the future).

A recent video of the beautiful engine note of the B58.

Infotainment, HUD, ICE

The infotainment is marvelous with a clean user interface, a bright and crisp display with HD quality of text and images that appear in vivid colors.

The touchscreen is fast and there is absolutely no lag.

The music system is decent and can be enjoyed when driving in Eco Pro mode (in other modes the engine note takes over… LOL) but, when you turn the volume up to the high end, the quality of the music deteriorates. For such an expensive car, they should have given a Bang & Olufsen at the bare minimum.

The connectivity is absolutely phenomenal. BMW is supporter of Apple probably because of their connection with them. iPhones connect to CarPlay/Android Auto seamlessly and wirelessly. When I get in the car, everything is already connected and the music switches to CarPlay. For example, if I listen to music on my AirPods/Powerbeats Pro, I get in the car wearing them, the music is automatically transferred instantly to CarPlay. The same thing happens with phone calls.

Plus, switching between users like me and my wife is just as seamless. If she opens the car with her key, all the settings are according to her choice. But, 8 out of 10 times I drive the car, so we rarely use this amazing feature.

Head-Up Display (HUD) should be made mandatory in every car. It’s such a useful feature that we can’t live without it. BMW HUD is one of the best on the market, crisp, clear and of high quality. The HUD can be moved up and down depending on the size of the pilot.

Only downside, Maps is displayed on the HUD when using an iPhone. However, if you are using an Android phone or Google Maps, the maps will not display on the screen. BMW seems to be more pals with Tim than with Sunder. Haha!

Maps and songs, the playlist can be seen in 3 different places: HUD, instrument cluster and infotainment screen. Amazing technology.

I also have the park assist pack which is a useful feature as the 360 ​​degree cameras appear as soon as you engage reverse gear and the camera is HD quality and shows a view all around the car and even a view from top to bottom .

Everything works as well as the day we took delivery of the car. Super happy!!

Manufacturing quality

There hasn’t been a single squeak to date, creaks of plastic or anything falling out of the interior.

It’s built like a tank and we still enjoy a quiet cabin with no complaints on anything to do with build quality.

Original tires

I’m surprised the stock RF’s have lasted this long. According to the comments given by SA they will last longer as the current tire tread depth is 6 front and 4 rear. As a general rule, it is recommended to replace the tire when the depth is 3 (look forward to comments and advice from the tire experts here).

I will most likely change all 4 tires when the depth hits 3 at the rear as I don’t want to risk any further as I like aggressive driving and pushing the car on a daily basis.

At the moment I don’t have the same confidence in the corners so I take it with my foot on the gas and also I can literally hear them in the cabin as they were getting loud which wasn’t the case some 1000 miles before. And, we are going to have rain in the next two months, so we have to do a few more kilometers before and change the tires because there will be a serious risk of aquaplaning during the rainy season.

Average Fuel

This is another area where I am super happy. The B58’s fuel mileage is reasonably good for such a powerful engine and if I push really hard the gas mileage drops to 17-18mpg but since I switch between Comfort and Sports I get a pretty good average in 20mpg-22mpg city.

Just a comparison, some of my friends who own muscle cars – Mustangs and Challengers struggle to exceed 15 mpg.

Overall it was a phenomenal experience owning my X3M 40i and I love driving it every day and every mile. Fingers crossed that I can enjoy this beast for many years to come.
