The weather and roads are getting good here and I had the chance to do a few 0-60mph runs this morning. I am at 510 feet of elevation and 48 degrees out. My best out of 3 runs was a 4.19 seconds 0-60mph. I had slightly over 1/2 tank of gas. This particular flat road I like to use still had a few too many cinders for my comfort level so I am gonna wait until it is really clean before I do more runs to get a serious official time. I am gonna run this fuel out as it’s been sitting and get 5 gallons of Sunoco 94 and do some serious testing.

I said this a few months back and I am convinced under the right conditions the 50i M-Sport can do 4 seconds flat or under 4 seconds. You get the right humidity, temp, lose weight by limited fuel, and elevation and it’s gonna happen. It’s just a matter of when a owner nails a 3.9 time.
What I found more impressive was that I could get 4.40 or less in every run. It seems like I could do that time anywhere. BMW greatly under rates the performance of this vehicle. I can see how C&D got 4.9 seconds out of the 40i in the right elevation. They probably could get 3.9’s with the 50i in those same track conditions.
I have been talking this over with AndroidRobot with his runs and we both agree a under 4 second run is gonna happen on the forum this summer. He has already got an unofficial 4.15 at his elevation so it’s only a matter of time till one of us cracks the 4 second mark.

Yes! See, this is what I meant about how great the 50i is NOW vs. those folks wanting to wait for the M50i. The car is already amazing

We discussed this before with how under rated the "factory specs" are from BMW. Its always been that way. What is amazing with this powerplant is how much torque it has zooming past 60mph to triple digits. It seems endless and just as ferocious doing 0-100mph. I posted a bunch of videos of muscle cars that had to work the entire day to get under 5 seconds 0-60mph.

Once i get the 1200+ miles, i will be timing our 40i.... do you use launch control or is there a testing process you guys use to most benefit time (dont ask me to lose weight ? how do you time? I'll probably wont get the numbers i should, but just want to try.

Get a Dragy to use for timing. Check Amazon for price. You will want to experiment with launch control and without. Turn off your traction control. Use high quality fuel and dont fill the tank up to save weight. Ideally you want to only have a few gallons of fuel. Try to test on a cooler day as turbos like the cool dense air. I have been doing this for decades and there are alot of tricks to get the time down. I didnt do any tweaks on my runs today. This is why I think I can get a sub 4 second run.
One trick is to raise your tire pressure 5lbs over to reduce rolling resistance. Weight is the enemy so dont leave alot of extra stuff in the car. Even the weight of the wheels plays a factor. I am running 20"ers and would love to get a forum chart on what the factory wheels weigh from 20"-22". Rolling resistance in width of tire and weight of tire can be a bigger factor than many realize.
You wont believe what Chevy, Ford and Dodge does to get their times. They strip the car of all their seats and carpets. The domestic car manufactures really cheat to get their performance specs. My 911 C4S responds well to the type of gas and octane. Its the way Porsche does their programing. I think the 50i will respond similar to the Porsche in what it likes to run hard and fast.
Transmission efficiency is spectacular in the new X5. Horsepower gets all the attention but the transmission is every bit as important to real world performance. How BMW keeps improving a already fantastic ZF transmission is amazing. Not enough attention is focused on how good the transmission is in the new G05 X5.

TOTALLY CONCUR. Overall I love this car. I admit I considered waiting for the M50i, but I would have lost too much value on the M5 by waiting another 7 months between order and likely delivery that it just didn't pass the threshold of making it work. I'm glad I didn't wait. I dont regret offing a car I hated and gaining a car I love.

Still very much looking forwared to ordering M50i in Tanzenite Blue...I feel pulled everyday to go in and order but I am not in huge rush, no lease commitments.

I too thought of waiting but my 50i is good enough for a family hauler. I'm actually considering if getting a sports car looking into the M8. Or maybe another brand for a pure sports vehicle.

I'm thinking maybe when the M8 Gran Coupe has been on its 2d or 3d year and any bugs worked out, I'll have this paid off and then as a fun driver.........

That’s sounds like a plan. I have to be honest that the 8 series is calling me as well. I love the lines of the coupe.

We have a driving event coming up in May. I get to test drive the X3 M Competition and the M850i convertible. If no one beats me too it I'll post my thoughts on them. I found the information on the X3 forum and signed up for a drive, limited spots and you must sign up early to drive.

congrats, you beat my tine what device did you record the data with? We have having a huge storm with more hail so I can't test until then

My dealer has a Barcelona blue with cf roof they keep asking me to test drive. I honestly love the car in carbon black with cf roof. It looks like the bat mobile. Total bad azz. I am not in a position to be dropping another $125k after the 50i purchase. I don’t have the garage space at this time anyway.

So, not a draggy or officially timed... I test drove a 50i last Friday (down Spicewood Springs if you are familiar with ATX) and had a new Range Rover SVR trying to keep up. Once we hit the highway (Loop 360) it attempted to pass me, and it just couldn't. Those have 518hp, and the 456 hp in the BMW was too much for it.

Man I've test driven quite a few cars down that road. Must suck to live there

That's the color of the I saw with the CF roof. $125k isn't bad considering what you get. I don't think a test drive would hurt Your 911 will handle better I'm sure. I think people know the value of your opinion, maybe they should pay you for the service


I'm curious to see how the M8 will be given another 100+hp and torque + M X-Drive among other things.

I'm not one to race but I have kept a hellcat or two from passing (mainly because the driver's of then here are assholes and will brake check you even if you move out of their way)

Dragy. I want to do some tweaks before I get serious with timing runs. My low elevation should yield 4 seconds or maybe sub 4. We will see. My wife could get 4.40 second times out of the 50i. It did it effortlessly every time. BMW really was conservative with their 0-60mph time of 4.60. I really think a sub 4 is going to happen.

I had a Hellcat and M4 running hard outside of Orlando to Daytona and we all three put the hammer down. I let those in front of me and neither the M4 or Hellcat could pull away from me as we all owned the left lane.
