Article: Evotech tuned BMW naturally aspirated S85 V10 E63 M6 versus an Evotech tuned W216 CL600 M275 Twin Turbo V12 mile long drag race

[SLS AMG]

Magnificent Mercedes-Benz CL600 with 650 hp will fight in Gran Turismo class. It will be interesting to see possibilities of modified bi-turbo V12 on upcoming Unlim 500+ 19.05.2013.

I guess that's the monster top end BMW guys always talk about....CL just ran out of breath..

Yea the 600 series really aren't impressive for what they are being a huge 6.0L and having twin turbos ... They have really poor flowing heads (exhaust and intake ports) which really restricts there top end power combined with the "old school" 3 valve design + low rpm limit = merr top end... They are down low and mid range beast tho and might surprise someone at a stop light if they can grip.

Very interesting race here where the top end of the S85 V10 in the E63 M6 impresses. The CL600 has a 5.5 liter V12 with two turbos plus a tune from Evotech which greatly increases the torque of the V12. The problem with the M275 V12 motor is the low redline, relatively poor heads, single over head cam design, 3 valve heads, and 5-speed transmission. Think of it as a tractor. Not to mention the 4800 pound curb weight which is almost 1000 pounds more than the E63 M6.

So even though the M6 is lacking in comparable torque the S85 V10 is a much more advanced design of an engine that breathes much better up top. Thanks to its lighter weight (not often these days one gets to say the BMW is the "light" one of the two cars) and top end design the M6 is able to walk away. Great race showing old school Mercedes brute force versus BMW high revs. Sadly, these days are gone as now BMW is taking more of a Mercedes-AMG approach. This race goes to show raw power/torque are not everything.
