Or…just compare it to the standard M3. Not the M3 Competition that is like an M3 with a tune and all the tricks thrown at it that’s 20k more than the standard M3
Actually the M3 Comp (auto) isn't much more than the M3 Base (manual). The comp comes with the upgraded wheels (1300) that you want anyway so the price difference is only 2600 dollars to get the comp. Basically think of the comp as the auto m3 and the base as the manual m3
The price difference is actually less than the upcharge to get the auto in the 4 or 5BWs.
All the expensive features you can option on the comp you can also option on the m3 base and basically most are tech or cosmetic things rather than performance stuff.
The m3 comp xdrive costs a bit more still, but not out of line with what most manufacturers charge for AWD option.
BMW is essentially giving the comp tune for free.
Don't think of the comp version of the s58 as an upgrade, that's just the normal state of that engine. Think of the manual version of the s58 as a downgrade.
I think BMW structured it this way instead of just calling it M3 auto or M3 manual is because they had to so severely neuter the s58 so it doesn't explode their manual that they half assed. This way it doesn't seem like you lose all that HP and torque when you check the manual option box. BMW basically bundled the desirable wheels and the shadow line trim (blacked out trim that is a no cost option to charge) with the automatic, called it a comp and hoped no one would notice.
Look at the trap speeds in the C&D tests for the comp vs base M3. It's like a 125mph trap vs 117mph trap. The 8 speed auto helps but that's a huge difference. The comp is like 5 seconds faster to 150. It's way more than a 30hp difference can explain, that's nearly 4BW to 5BW difference by C&Ds tests.
I looked heavily into getting an M3 comp xdrive after ordering the 5BW and coming here and realizing that the order might never get picked up.
I had a spec all picked out and ready to order one at MSRP, but got the call the 5BW order was picked up. So I ordered an X3M comp for the wife (she insisted on an SUV). Even the X3M comp carrying 800 pounds more than the M3 manual and shaped like a brick is faster in the trap and faster to 150.
Sure you can tune the base M3 s58 back to its comp form but you gotta figure BMW neutered it so hard for a reason. I don't think they have alot of confidence in how much torque it can handle.
