Are you happy with the 40i. Do you wish you went m60 to more closely mirror the x7 ?

I feel fine with my decision - having both to choose from is nice though. I could easily throw a JB4 on the 40i and match the raw speed/performance but its not just about straight line speed.

The steering calibration of the M50/M60 is the thing thats the most different vs. the 40i. Everything in the 40i is lighter. They're both fast cars, although I'd describe the 40i as quick and the M50/60 as powerful - the difference is how substantial the M50/60 feels due to the substantial heft of steering that's balanced w the power.

I honestly dont miss much in the 40i - but the V8s have a certain amount of gravitas in the way the total package is calibrated that gives it a powerful, confidence inspiring driving profile.

Thanks!
Both models are incredible cars which is why it’s so hard to choose between. I bet many wish the 40i was more of a dog to make decisions easier!

The one thing that bothered me on the m550 and the m50 is the weight of the front end / total vehicle. I do tend to gravitate/prefer the setups that are lighter quicker feeling. I think a 500+ hp 6cyl is the way to go!

Well then here’s your answer.

A bit off topic, but has anyone driven an sq5 recently to compare to 40i. It appears that the entry level x5 is faster.

I had an SQ5 when I was first test driving the 40i/M60i. To me, it felt about the same in straight line performance but thought my SQ5 was definitely sportier than the 40i. Plus it had a better exhaust note

They’re also different categories of vehicles, so I guess it depends on what you’re looking for. We outgrew our SQ5 and needed to go a size up, but I still wanted something on the sportier side so that’s how we landed on the M60i.

Yes, I’m on 8.5.

Anyone getting in the 5's doesn't know how to do the proper launch protocol, has some gnarly conditions working against them (100 degree day with 14 passengers, full tank of gas, up a mountain, and an elephant for luggage), or both.

My gut feeling is no way the 40i is in the 5s but rather high 4s. As posts in one thread calls out, ambient temperature is definitely in play due to the turbo involved. Although granted the media reviewers (C&D started it) use a 1ft rollout that's BS. That said also in the threads, i.e., BMW's conservative numbers is absolutely true.

BMW spec's for my M850i states 0-60 in 3.6 seconds. There are countless real world tests that state reality being 3.3. Beyond the official reviewers stating that I have draggy results at 3.2/3.3/3.4 with the ambient temperature a key factor. 110 degrees here in Phoenix 3.4. Best run was when it was in the low 50s being the 3.2.

Yea I prefer the bigger cars too (2 kids). I was looking for a comparable in that high 4s low 5s acceleration and the sq5 came to mind. These figures are nothing to complain about but Having the low 4s high 3s is a night and day difference.

100% the LCI would be in the 4's. My pre-LCI 40i hit 4.04s with 1ft roll out (4.25s without 1ft) and it only has a stage 1 tune. I struggle to believe that it would be much above 5 (if at all) before the tune, and thats 40bhp down on the LCI as standard.

I have a Dragy and I can turn off the tune at will so will test it in stock mode when the weather here improves.

On one of my first BMWs, the auto hold was a bit 'rough'. The dealer was able to adjust it so you had to actually be stopped before it engaged, and it was smooth from that point forward. IOW, it should be able to be adjusted. I don't remember any clunks when it engages on my X5, though, or the other BMWs that I've owned.

Yeah, that is a 4 flat, very strong Dude. Good job.

Beyond the slight shudder I feel at engine start (not a fan of that but smoother than a 4 cylinder) I think the LCI ASS is seamless. One problem is when you are crawling very slowly toward a garage wall or something and the ASS activates and then wants to immediately restart the engine. It will occasionally kind of stutter a bit. It should probably keep the engine running if parking sensors detect nearby objects.

Thanks.

Yeah its surprisingly strong but it has been consistently hitting those times with both Dragy and the Torque OBD app.

This will make you laugh - the best Dragy time I've had is actually 3.96 with 1ft rollout, but Dragy deemed it invalid due to a -4% slope. However, and this is the funny part, other runs on that same road have been valid as it read the slope to be less on those runs

Neither here nor there in the grand scheme but you know what its like trying to break a barrier, if I could just get something valid starting with a 3... I'd sleep better at night

Interesting, keep up the good work and keep us informed.
