Serious question, other than power, what does the 50 offer over the 30? I appreciate your input
It does not justify it self with an extra power by number that you see the difference on paper.

Inline 6 cylinder B58 is much more advanced and pleasure to drive at given any condition. U need speed, better handling response you name it u get it. At the end BMW are a driver oriented car , for some just the badge and for some performance that matters when you sit in the car and drive you feel the power.

Lists of this trim can go longer, but its worth every penny, surprisingly its fuel efficient for that massive 6 cylinder, ofcourse slightly consumes higher that regular, its still practical and a performance car. U will feel special every time drive, no lag. Mild hybrid smooths out the initial ignition to stop and go just like the breeze, steering response is precise. On a highway i enjoy this car every second, grounded on conering, great on overtaking . Its a all in all car is what i can end this with.
Well put. I was surprised by the reaction I got to saying I only want the I6 in a BMW. It is their iconic automotive signature.

The B48 has been in production longer than the B58 so I don鈥檛 know why you think the B58 has been around longer.

Everything you say about power and overtaking for the 6 cylinder I can say for the 4 cylinder. It is an incredible driving experience. And the 4 cylinder weighs 200 pounds less than the 6 cylinder so its cornering is actually superior.

The B58 is generally more durable than the B48 thanks to its inline-six layout and stronger closed-deck block, which handle stress and heat more effectively. It also features a more robust cooling system, helping it maintain stable temperatures under load. As a result, the B58 typically offers better long-term reliability and higher tuning potential.

I've been driving B48's since 2015 on F30, F36, and G26 platforms without a single hiccup while experiencing terrific performance. So I'm not sure about this durability difference.

Both engines are amazing and the 6 cylinder is certainly more powerful than the 4. But the real world performance difference is marginal at best, especially installed on heavy SUV with 65 mph speed limits and the typical driver averaging 32 mph each day. Drag racing between stop signs enroute to Home Depot is rather pointless.

Now ask ChatGPT to list the B58 issues (Spoiler: There are more than the B48鈥檚).

An X3 is not a truck. Every car built today is a people mover.

No.

I get it鈥攜ou like your 4-cylinder X3. There鈥檚 nothing wrong with that. The X3 30 model is a very good vehicle for a lot of people, and I鈥檓 sure it outsells the M50.
But don鈥檛 kid yourself into thinking the differences are marginal at best (insignificant).

Not lovin' it tbh. I never owned a MB but a family member has the GLE AMG and a neighbor has the AMG 63 and they are nice but the cost is ridiculous and they have some issues. And, no maintenance is included, whereas with BMW you coast for 36mo.

Yeah, new design is very polarizing. German luxury car makers must all be drinking from the same well, LOL! I would only consider the current gen X5 against current gen GLE for my next car.

I hear you about not having maintenance included in a MB purchase. Believe it or not, some local MB dealers may actually throw it in but this is rare. Don't believe for a sec that BMW included maintenance is not built into the MSRP. It would be a slightly cheaper car if weren't.

Absolutely No denial B48 is a good machine, both the engines are good at what its made for. I shared my experience since I owned both the engine and there is a huge difference I felt instantly and exactly what i was looking for. Personal choices are not questionable but sharing experience could be helpful for someone. B48 has been long but the revoulution of B58 is incredible in shorter time and fortunate to have been improved with the recent years on newer models on both. Doesn鈥檛 matter what car we drive its the driver who makes the car feel good , lol. Its just an excuse to have a powerful car haha.

A few quick words: in this time of rising gas and petrol prices, my B58 has been getting 30mpg on daily drives in the East Tennessee hills, even with sporty acceleration. Gotta love it.

My B48 showed 550mi of range after its last fill-up. It's getting 125 more miles per tank than my B58 X7 and that's with a 17 gallon gas tank vs. 22 on the X7. If you want to talk about fuel economy, the 4 cylinder can't be beat.

Kilka s艂贸w na szybko: w dobie rosn膮cych cen benzyny i gazu, m贸j B58 spala 艣rednio 30 mil na galon podczas codziennych przeja偶d偶ek po wzg贸rzach wschodniego Tennessee, nawet przy sportowym przyspieszaniu. Trzeba go kocha膰.
M贸j B48 pokaza艂 550 mil zasi臋gu po ostatnim tankowaniu. Przeje偶d偶a o 125 mil wi臋cej na jednym baku ni偶 m贸j B58 X7, i to przy 17-galonowym zbiorniku paliwa w por贸wnaniu z 22 galonami w X7. Je艣li chodzi o oszcz臋dno艣膰 paliwa, 4-cylindrowy silnik jest bezkonkurencyjny.
I suspected you were stupid; your family has probably known it for a long time, but now everyone knows. The X3 has a drag coefficient of 0.28 and weighs 600 kilograms less, while the X7 has a Cd of 0.33 and weighs 2.5 tons. The difference in fuel consumption doesn鈥檛 come from the engines, but from the difference in the size of the cars.

I鈥檓 well aware of the weight difference, I just didn鈥檛 expect the delta between performance and fuel consumption to be that vast.

I suggest you leave your personal attacks about my family out of this.

Also his X3 is running a small 19" 245 square tire setup. What's the smallest size for the X7 btw?
