Correct.

Winning is winning.

They should've done several runs and switched drivers.

Looks like 1/2 tank of fuel and temp at 22.5c or 73f.

Just because LC was engaged doesn't mean it was used properly.

The video piece so well done and to the point, unlike many others that have 20 minutes of blah blah blah. Impressed with BMW. Like an underdog it worked hard and came out as a winner, actually by a lot.
P.s. would a video where BMW looses be posted here?

[moff]

No journos seem to be able to launch the X3M or X4M and to be fair it's not straightforward.

The car must be held on LC or just brake for at least 2 seconds to build boost or there will be lag as shown in this video and many others.

Not great for the traffic light Grand Prix but that's life with the S58.

Lots going on here.

Poor LC from X4m, Alfa is lighter and has more torque below 3k.

I've looked at family friends quad and its poorly build built and tacky inside...and then there is the issue of their famous reliability!

Fair statement but my post / response wasn't about proper use, it was replying to show LC was engaged.

I also said it was debatable if proper boost was achieved for the launch. Having launched mine many times, I can confirm a 1 1/2 second hold does not render a good launch. That being said, I never had a 4.?? time with poor launch at this point.

Now they could have filmed that 15 times to get all their footage and that particular launch just made the edit, not sure. They mentioned they rented the runway. I guarantee if I rented a runway, I'm doing more than one 1/4 mile run but hey, that's me. Maybe they are the Martin Scorsese of 1/4 mile runs and did it in 1 take.

Again, my posting the picture was to illustrate if in fact LC was used as there was question if it was used or not.

Most of these productions are for entertainment purposes only. I enjoy watching them but never rely on them to provide meaningful data as they rarely (if ever) share DA, octane, tire psi, estimated total weights, ..., much less entire Dragy results to allow interval times to be evaluated.

I've been searching for formal 1/4 mile slips (not Dragy) on the AR SQ, MB GLC63 and S, Jag F-Pace SVR to add to the spreadsheet for comparison with my X3MC's runs but haven't been successful.

They have the same amount of peak torque at 600nm and the S58 makes max torque at 2600rpm and launched at that RPM so where is this additional torque from the Alfa?

I’m actually not sure if he used the LC at all or simply brake torqued it. X3M has the best high end hp curve in it’s class and that’s why I love it so much. Absolute beast at high rpms.

im patiently waiting for the m3/m4....

I’m patiently waiting for the i4. The base RWD i4 (sDrive 80) is supposed to make 520 hp from a single electric motor. Can you imagine the performance of the “M” xDrive i4 models? I also love the new aggressive kidney grille design.

How much money are you investing on changing out the grille and front bumper?




Ok the race...

- Better to use some LC then No LC
- I wish they just showed a 1 shot from start to finish from a car angle to see how the race actually played out and not mishmash 6 camera angles into it
- No surprise the X4 reeled the Alpha eventually, a couple videos show BMW Ms having very strong top end (60+ mph)

[nathanm4]

X4M of course. I drove a regular Stelvio the other day. It was horrible. If Alfa keep doing what they are doing now, the brand won't last long.

Alfa launch is brutal!

X4m should have smoked it from the beginning

Car & Driver did (hence their stellar 0-60 & 1/4 mile times for both the X3M and X4M Comp) but they seem to be the masters of getting the best numbers out of cars.

Max Well, and several other people here, have accurately reproduced their 0-60 and 1/4 mile times, so C&D times are absolutely legit.

C&D is one of the only mags to adjust the times based on current temp and altitude.

How did you come up with this thesis, Doug?

[Mako]

Simple fact is both cars have been tested at 0-60 in 3.3 seconds when launched correctly. This video does not show that... meaning there was a launch issue.

Also could have been staged for drama, show one car crush it off the line and end up losing...

In all speed tests these things are almost identical. I like the Alfa for certain things but in the end the BMW is a better overall car (fit/finish, comfort, infotainment, reliability...)

[AlexFL]

C&D times for X4MC (Stelvio QF):

0-60: 3.3 (3.4) - even
0-100: 8.0 (8.8) - clear high end advantage for BMW
0-150: 21.5 (25.9) - very clear advantage for BMW
Rolling 5-60: 4.6 (4.4) - advantage for Alfa due to lower weight?
1/4 mile: 11.6@119 mph (12.0@115 mph) Bimmer wins
