RWD vs. AWD... WHICH IS MORE POWERFUL? (Dyno Tested)

[@TheBimmerMan]

yeah, Xdelete will probably means there’s gonna be X3s and X5s sliding around like Formula Drift cars 😂

[@IAmLeutrimTopalli]

Lawsuit paradise for lawyers

[@mateo...]

Excellent, thank you! Can you do real world x-drive vs rwd testing, like w 0-60 and 1/4 mile times?

[@KiesMotorsports]

👍🏼

[@garygrenier]

I have 2 xDrive N54 powered cars, an E60 535i xDrive and E90 335xi. The 335 is stage 2+ E30 tune, with Ebay intercooler, ARM c@tless downpipes and DCI (with PE Mod mufflers) and runs 0-60 in 3.6 sec on a cool day. The 535 has almost no actual performance parts, just a DCI and strait piped stock muffler, nothing else other than keeping the plugs and coil packs fresh. Stock intercooler, stock catted DPs, MHD Stage 1+ E30 tune XHP Stage 3 trans tune, and has done a best of 3.93 sec 0 - 60 on a COLD night. There is no way a RWD car with the same mods could come close. The 535 runs about 12.2 in the 1/4 at 113 MPH, which is more in line with the RWD car with the same power. Bottom line, the 4WD cars are slingshots from 0 - 60 and don't give up much in the 1/4 mile. Best of both worlds, and required here in New England!! I do think that xDelete does allow more power to the wheels but it would be lost in wheel spin. I have tested and can't run even 4.7 0 - 60 with RWD on the 535. That being said I do wish I had a RWD car as well.

[@evadexxx2898]

​@@garygrenier what tires are you running on the 335?

I think in the rear world AWD would be more useful but it’s amazing you can disable and enable it as you please.

[@abelucious]

I own a stage 2 fbo E60 535xi with a 6 speed manual and I've been experimenting with XDelete for a couple of months now , first time converting the car to RWD it felt more raw and wanted to go sideways when flooring it in 3rd gear going 70 mph , that gave me the impression of it being faster but it was just a feeling , what I did notice is how good BMW x drive system is when launching from standstill comparing to it being RWD , now I have XDelete but I like having all wheel drive with the amount of power I have it makes a huge difference .

[@chubeecrypto9857]

Awesome Vid. I have 435i xdrive gran coupe. 440 crank hp. As a frequent roll racer I thought this XDelete may give me an extra boost. I bought but never installed as i luv AWD. Now I know 3hp 8tq. You wont feel that and it wont win you a race. But if you really want to see/feel a difference: XHP Stage3 trans flash makes all the diff in the world for an XDRIVE BMW.

[@M5tubee]

I have a 135i with xhp stage 3 that helped the 6at alot... but on 640i xdrive zf8 i have yet to get xhp but the zf upshifts so fast already how does xhp change it granted downshifts on the zf8 are slow my xhp zf6 downshifts much faster

I had to choose between rwd and awd on a 330i and went with rwd. I’m happy with my choice. I must admit that xdrive is way better off the line. I like the way the rwd turn and handle

[@ziggysoentjens3735]

You should do some xhp vs bootmod3 test on the dyno so we can see how good the OTS tunes are.

I’ve got MHD and bootmod3 for my car, and I’m in NJ if you want to dyno a f32 with both for comparison.

[@JoshNormandy]

As much as I love my tuned rwd 340i, I'd love to have the hookup of awd!

[@DjNikGnashers]

Not for me thanks. It's too safe, too boring. All you achieve is a faster launch, but that doesn't take any skill, just point the steering wheel and mash the throttle. I'd much rather have to actually use skill to launch, and then have to actually balance and drive the car myself. My M140i is only at 411bhp/576nm now, but next month should be 460-470bhp, and I can't wait for those roundabouts on a damp morning !!!

My question is if you wanted to keep it in rwd for the summer and a few months switch it back to awd when it starts snowing and vise versa will that affect your drive train or damage anything since the car was made to be awd? Just curious

[@andrewbossman4970]

I run my xdelete in rwd all year, unless it's supposed to snow, that's the only time I turn xdrive back on... no issues at all always works when I need it! If you never tried xdelete I definitely recommend it!! I have an e60 535i with n54 full bolt ons..in the process of upgrading the fuel system to run more e85!

[@CRDYMN]

I know the answer is late, but the only thing xDelete does is open the clutch which sends power to the front when you go 180kmh/110mph, xDrive automatically opens the clutch constantly and only closes when needed, because the power gets distributed better, meaning that your BMW already goes full RWD after a certain speed so its safe to constantly put it in RWD, just keep in mind that you can damage your xDrive when the thread difference of your tires in the front and back are too high

[@berdzena8797]

[@dtrain8335]

Soooooo how does it pull on the street AWD vs RWD? In my experience AWD cars don't seem to push you in the seat nearly as hard as RWD cars. I've been in a few RWD cars that I know are slower and make less power but they "feel" faster because you can just feel the front end pulling up.

[@BMWDIYGuy]

Did I ever tell you about the guy who brought me his AWD F32 that was missing the right front drive shaft? Clearly someone had hit it with xdelete to make it RWD, and sold it to this poor guy.. literally the drive shaft was missing.

the result differences is probably in the dyno. your drivetrain costs you HP and TQ. AWD has more drivetrain to turn around. When all the wheels are back on the ground. The FWD-train propelled again true the asphalt

[@3ternalHustle]

Its electrically balanced so its just transferring the power differently

[@colin55594]

It's weird how little views this channel gets. So much better then everything else

[@JTAlweezy76]

Bryan, does the xDelete let you specify how much torque, % wise, is applied to the rear vs the front wheels with the app? Bmws are typically 40/60 front/rear. If you could modify the torque settings, maybe there is a sweet spot where power and torque is optimized across the front and rear for best performance. Im also assuming, bmw already figured that all out. Just curious. Great video!

[@blahx9]

Not for a f3x - maybe with the new xdrive systems ? This is an on /off switch it just decouples the clutch packs in the transfer case to ‘disconnect’ the front

You’re only removing it on the dyno. Once the front wheels are spinning because the back has to push them, that whole front drive system is spinning again, adding it’s weight back into the drivetrain

I feel like this would be slower than a true rwd 340. Bc of the added weight of the awd system. If i were in ownership of xdrive model id just leave it as. I only see the delete being useful if you wanna hoon around a bit drifting on wet roads or something otherwise pointless no offense
