Our editors all agreed they'd prefer the SL65 AMG to the M6 convertible for their personal use That would be my preference too if I had to pick one out of the two :)
For a real sports car, I would look elsewhere for something significantly more light weight, & with a good manual transmission preferably . . .

Dimensions

Exterior Dimensions & Capacities
2007 BMW M6 Convertible 2007 Mercedes-Benz SL65 AMG
Length, in. 191.8 178.5
Width, in. 73.0 71.5
Height, in. 54.2 51.0
Wheelbase, in. 109.5 100.8
Curb Weight, lbs. 4,373 4,518
Turning Circle, ft. 41.0 36.2

OMG, these cars weigh 4400 and 4500 lbs. The SL is quite smaller and weighs more.
That is more than a HYBRID GS 450h and as much as a LS 460.

Wow.

And yes, the SL 65 for me.

yeah of course I would also go for an SL65
but the price is the obvious reason for the differences

$108,795 BMW M6 vs a $189,375 Mercedes SL

if i had to pay for this car, i wouldnt get either
id get a porsche 911 turbo instead :D

a well written review for the elite convertibles
that V12 bi turbo is simply insane

i love this quote...

"Compared to the M6's frenetic V10, the SL65's V12 makes almost twice the torque at one-third the engine speed. Even at 1,000 rpm, the biturbo V12 makes 420 lb-ft of torque, which is more than the M6's maximum of 383 lb-ft at 6,100 rpm."

haha thats so insane...i'd take the Benz anyday.....bimmer lost its touch

420lb ft at 1000rpms? :eek2: Bwahahaha :D

That's nuts.

I wouldn't get the SL65 AMG brand new we all know the depreciation of V12 is nuts.

But throw in some Renntech goodies in there, you've got a high 10's- low 11's daily luxury convertible boat. :p :p

Isn't the price difference almost 80k USD on these two cars? I mean ok, on pricey cars that's not a huge deal; but that's almost 100% of the M6's MSRP. Heck even the SL55 is like 30k more money. I'd much rather have the SL65, but that's a mighty large price diff to be comparing.

this week's top gear episode was showing the brabus tuned version of the SL65
even more monstrosity
the traction control system had big problems keeping the car gripping so u can see the car wobble A LOT when it is cornering

Yes the SL65 is WAY overpriced compared to a SL55 & the SL600, it's hard to justify in terms of increment value, it's for those who have more money to blow than they know how & just want the top of the line SL model with it's exclusivity, but personally, I would still take the much lower prized SL55 or SL600 over the M6 convertible easy.

Interesting how some of the Japanese sporst cars (IS-F, LF-A, GTR) are getting automatic trannys with 7-8 speeds and AMG opted for a 5 speed. Maybe they've already realized no need for more than 5 in this type of car?

The 8 speed is simply too weak for a car with 700 lb/ft torque. The IS-F with its 350 lb/ft is childs play compared to SL55/65

738lb ft of torque... :eek2: even starting in 5th gear, I think it would still be able to beat many cars out there. :)

Ah, the MB is almost twice the cost. I would expect more performance. :egads: Common sense don't ya think. ;)

im sure the AMG SL65 hauls ass but what about at the corners? I've seen plenty of times where a N/A S2000 beat a Skyline GT-R at the track over here.

for 200k (and if i had to get a Mercedes of a BMW), I'll take a 550i M-Sport and a M3. Thats more than enough for daily use and at the track for me. But that is friggin insane that its a Mercedes thats meant to be used on a daily basis and not a weekend Lamborghini. It still has all the Mercedes-Benz like warranties and whatnot right??

SL happens to be the only vehicle in todays MB lineup that I happen to like.

The 7speed from Mercedes can't handle that much power. Even the 5speed can't. The SL65 engine can make more than 1200lb-ft torque, it's detuned to about 800 for reliability (tranny) reasons.

The RENNtech guys have software they are testing to unleash all 1200lb-ft torque but as they run the car through the dyno, the transmission just slips and sits in neutral. That's power.

If anyone say Topgear a few hours ago, they tested a Brabus SL55 bored out with some goodies, that car had enough torque as it was (I think it was a base SL55 modded, they said bored to 6.3L).

yup, totally agree. i would probably choose the sl55 or sl600 over the m6. m6 is a good sport (track) car, but for every day driving the sl is better imho. the sl65 is very nice and tons of bragging rights, but for 180k, i would be looking at some other cars instead

Yes, but how do you choose between the 55 and the 600?

SL55 is more tightly tuned, drives sportier & rides stiffer, & is also lower. But the interior materials of the SL600 is better(premium leather, alcantra lining, wood & leather steering wheel etc.) & comes standard with more extra's . . . it's personal preference.
I think the SL55 holds it's value better than the SL600 though. Those V12 mercedes' depreciate quite quickly.

andrew brought up some very good points on the depreciation. if money is no factor, i will probably go with the s600, the interior is quite a bit nicer, and imho the suspension of the sl is quite stiff already, so s55 (haven't driven it yet) i imagine would be even stiffer?

The SL600 is a no brainer. When you're dealing with a pig, it's not like a few pounds here and there make a difference.
At least with the SL600, you can chip it and get mad hp. 10 sec 1/4mi!

You would have to do more than chip it to get into the 10's. A chipped SL65 would have a hard time doing that. To some one elses comment on the 65 not being very different than a SL 600. All that I can say is do your home work. The AMG's are more than some badges and 4 tailpipes; the chassis is tuned different, the exhaust is different, the brakes are different and naturally the engines are totally different--- in one word different. And one other thing before you pass judgement drive any of the AMG's you will be surprised at how any of the pigs drive and most of all how docile they can be when driven sensibly but that is not easy to do when you have all of those controllable ponies at you beckoned call.

Oops, chipped with an airbox...
:D

it was the SL65 bored out from 6L to 6.3L

I thought the SL was a 5.5 to 6.5 or 6.3, one of those.

yeah, i believe the sl600 is just 5.5L v12. it's not 6L

and the SL65 is just 6L

kinda like AMD naming their processors 3200+ when they are like 2GHz

doesnt matter what the name is, the engine produces way more than enuf power
lol

theres really no point in brabus tuning the SL65...
unless they invent some super sticky road tires

Oops, yeah the SL65 is a 6L engine.

AMD's method is actually different, they were just trying to keep up with the Intel P4 stuff. :)

I think this is a really stupid comparision... I'm not trying to favour BMW because i don't really like the M6 that much at all, but i do find that it's somewhat an unfair comparision. Why didn't they compare the SL55 and the M6... it would have been more even.

Both are amazing. I'd be proud to own either car.

But purely from an aesthetic point of view, I'm not too crazy about the 6 series convertible top. I took a good look at one a couple of days ago, and it just doesn't look right to me with the top up.

But considering that BMW will release a convertible hardtop 3 series, perhaps a hardtop 6 is around the corner. Now that would be beautiful...
