Engine Output Discrepancy - Torque figures?
The Euro spec says 256 kw, 365Nm torque (269 ft lb) The CSL spec says 265kw, 360Nm torque (270 ft lb)

How can one have more Newton/Meters of torque (365Nm vs 360Nm), but less foot-pounds of torque than the other (269ft lb vs 270ft lb)? They are two different units of measurement for the performance characteristic.

I think there is some discrepancy in the unit conversion from one of the sources, but I haven't looked into it.

Separate Page for S54
Hi,

I really think the S54B32-part should be broken off to it's own page, since it is totally different engine and totally different development cycle from the M54 (the only commonality happens to be that both have the numbers 54 after the first letter.) There are tons of stuff I could write on the S54B32, but I think it should have it's own page first. Even more as the S54B32 is still alive and being used on new cars, but the M54 is not...

Best regards,

Perhaps a link to this press release... http://www.users.fast.net/~slafredo/cars/bmw/E46_M3/press_release.html

It discusses the S54B32 in lots of detail

Specific Output
Someone put this as the second-highest production vehicle specific output: The Honda S2000, the reigning champion, has 90kW/Litre, the Porsche 911 GT3 RS comes in a close second at 85kW/Litre, and the S54B32 comes in at a dismal 79kW/Litre.

DOES ANYONE NOTICE THE HP/TQ SPECS ARE CONFLICTING FOR THE 3.0L BETWEEN THE GRAPH AT THE TOP AND ESSAY AT THE BOTTOM? —Preceding unsigned comment added by 216.119.49.170 (talk) 17:16, 16 April 2011 (UTC)

M54B30 Discrepancies
I was just going through my reference material for the North American 330Ci, and I noticed a few discrepancies between this article and the reference material.

According to both the Factory Service Manual and Bentley's E46 Service Manual, the M54B30 does not use forged, fractured-cap connecting rods; only the S54 engine does. The M54 uses conventional forged connecting rods.

Also, both those manuals (as well as the owner's manual provided by BMW) refer to the engine producing 225 bhp @ 5900 RPM and 214 ft-lb. @ 3500 RPM. While this difference could reflect regional variations in in both measurement and emissions controls, the distinction should be made. — Preceding unsigned comment added by 68.144.193.169 (talk) 23:11, 20 June 2011 (UTC)

Orphaned references in BMW M54
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of BMW M54's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "usautoparts": From BMW M40:  From BMW S38: http://www.usautoparts.net/bmw/engines/s38.htm From BMW M10:  From BMW M43: http://www.usautoparts.net/bmw/engines/4cyl.htm From VANOS:  From BMW M60: http://www.usautoparts.net/bmw/engines/m60.htm From BMW 3 Series (E46):  From BMW M62: http://www.usautoparts.net/bmw/engines/m62.htm</li> </ul>

Reference named "carpages":<ul> <li>From BMW M3: </li> <li>From BMW 3 Series (E46): </li> </ul>

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 17:38, 19 May 2013 (UTC)

ZHP stats?
Is there a particular reason that the engine from the US-only ZHP is not listed among the versions of the engine, as it does have different power figures and a higher redline? — Preceding unsigned comment added by 69.241.122.68 (talk) 20:21, 29 May 2013 (UTC)

Power units
Hello. Just a courtesy ping, in case you take issue with my latest "anti-metric hp edits" here. The reason for removing Pferdstarke is that I do not believe it is closely linked with vehicles using this engine, and it isn't necessary for verifying the references here.
