That's not surprising, the X5 has a huge power band through redline and I think it really shocks the competition

What's your elevation for testing? I can't get anywhere below 2400ft without going south and that would be a long drive just to test some speed.

510 feet at the road I test by the Susquehanna river. You can see at 1900 feet below where you test a sub 4 seconds is possible.

I wasn't trying to race him per se, just accelerating the same as I would in my M40i, he was pretty obviously trying to race me though (revving his engine and some tire squeal). I still found it amazing how quick and smooth the 50i was.

I really don't try to either but I also hate being passed by psychotic drivers out here (they probably think I am one but not letting them sometimes ) I guess I'm tired of being brake checked / almost run off the road for no reason. It's a West Texas thing unfortunately

Sounds like the perfect place for a proper test. I suppose some of our BMW brethren in Houston can test at sea level (on a leash humid day)

Okay you two. I really like both of you guys and your posts are great, but the G05 50i, while an amazing car, does not compete in any way with a Hellcat. Reality check: Hellcats are 600 pounds lighter and have 140 or so more horsepower than a 50i. If a Hellcat was being driven aggressively, the G05 would have zero chance. They would be sucking the crystal shift handles right off the G05 console as they fly by.

Actually the 50i M-Sport can do a faster 0-60mph and do it in about every run. The ability to harness the power is the difference. On the top end of course the Hellcat is going to be faster but most are not going 110mph+ in traffic.
Look at the real world 0-60mph times and how long it took to get a decent run.

It was all they could do to get a under 5 second run. The best the pro driver could do was a 4.7 on a drag strip. My wife can get a 4.4 second run all day long in the 50i loaded with groceries.

How about a Z51 Stingray struggling to get below 5 seconds 0-60mph. Not even GM’s own driver could do it.

Corvette Grand Sport with Pro driver 5.17 seconds 0-60mph.
Go to 2:08

Shelby GT350R. Struggled to get under 5 seconds and best time was 4.53 seconds 0-60mph.

The take away is what certain manufactures publish as performance times and what extreme lengths they went to get it. (like removing the entire interior and using drag tires. Non production floor engines and transmissions that were heavily massaged for optimum performance.). Many know this has gone on for years but the difference is today the average owner has access to cheap and accurate timing equipment to verify the real world performance. Think of it as a “ Lie detector” for manufactures claims.

I sit corrected. The G05 50i is impresessive indeed.

It's cringworthy to see videos of these supercars struggle to achieve low times: All that power and can't put it down.

There's a video of a Hellcat doing 3.5 so it can be faster under perfect conditions, but your point that the 50i can consistently put down low times is a testiment to just how great it is.

Thanks for the education.

That’s really the point with how BMW engineers their vehicles. Their transmissions are incredibly efficient, damn near perfect. They also are very conservative with their performance numbers. They are just easier to drive fast in the worst of conditions. At a stoplight drag, the 50i will take a lot of high performance cars. It’s the ultimate sleeper if you don’t hear the exhaust. I wouldn’t want to drag race my 50i M-Sport with my 911 C4S with manual stick.
I bet the new X5M will take back the fastest SUV title in the real world performance shoot outs. My issue is when BMW goes to next level performance like on the M5, all kinds of reliability issues pop up. There is a trade off for everything. Most of use acknowledge that the 50i hits the performance sweet spot in comfort, speed, and reliability.

I was being serious. Maybe it's a traction issue? It shouldn't compete but somehow it goes and is still fun

The sweet spot of the 50i is 0-100mph and that’s were most all of your driving is at. High performance sports cars will overtake at triple digit speeds but up until then the 50i will take most. For the ultra fast sports cars, it will surely make them work for it if not scare them to death a luxury SUV is right there with them. For more pedestrian sporting cars like Mustang, Corvettes, etc... It will beat them in a drag.
It will take a awd high performance vehicle to give the 50i a match. It punches way above its performance weight class. The real world 0-60 times speak for themself.
I humbled a guy in his new Mustang GT that was on my bumper at 75mph on my last family road trip. Here I am with my 50i loaded down with a family of 4 and all their luggage for a 2 week trip. I put it in sport mode and put the hammer down. I jumped to 110mph so fast he didn’t even know what happened and tried to keep up but gave up at 100mph. I jumped 3-4 car lengths within the first 3 seconds. It was one of those epic moments when you see just how useful a V8TT in a luxury SUV can be. Like a big grizzly bear. They look slow until you piss them off and then you realize you can not outrun it.

The guy did X5 50i 0-60mph at3.8s

It looks real. i believe this is the first smoking gun of a sub 4 second run. It’s gonna happen and someone had to be first.
It’s certainly possible given how conservative BMW is with their performance stats. I am positive I can get a sub 4 second run if I work on it.

I would love to try but I don't think my 22" rim gonna make it works on sub 4 second even the weight of the wheels are lighter than my 20" OEM but I still feel the acceleration on 20" wheel pull harder.

[Np2014]

So true my M4 struggles to put all that power down unless under perfect conditions. My friends RS5 puts it down 24-7 with that awd. Damn it BMW hurry up and release the order guide for the 2020 X5 M50i with the new TT v8.

Guess there is no indication if it's been modded in any way. Dang tho

I'm pretty sure that is modified. I believe the maker of the video has posted here before.

The guy is on here and flashed a tune to his X5, he's making almost 600HP at the wheels Go look in the mods subforum or hit my link below.

Also, look at his youtube name vs on here, plus that looks like FL

I had my own 0-60+ run over the weekend, i was with my wife and 2 of her friends, i was fortunate to get a squeeze with a blue Audi R8! I eventually got behind the R8 a traffic light. What are the chances you get behind a Audi R8 on an open road straight away with a v8 TT 50i? At that point, my instincts kicked in and sport + mode appeared. My wife looked at me and said, “your not really going to do this?” I grinned back. She told her friends to hold on!

No one in the car said a word, the light turns green, and we both punched it! Roaring exhaust sounds of a 50i m-sport vs R8 was ON. It was absolute gorilla violence! We both rocketed straight and instantly climbing to 100mph... i let off. My 50i was on the R8’s bumper like chit on a stick and he never pulled away period. The 50i is that damn quick.

After achieving an insane rush, comfort mode was reactivated and I patted my X5’s dashboard ... “easy girl, easy, you did well”.

Competing with an R8 is pretty funny, even keeping up is a feat given the V10 I'm sure was under the hood (maybe it was a V8 model?)
