As you may have noticed, @AestheticsInMotion and I have had a little fun with you all over the past couple weeks, leading you astray and away from guessing his new ride. The one, the only, R55 AMG mommy-missile. For anyone living under a rock (read: not living on the internet) all weekend, here's his take:
What you may not have realized is that his new R55 is actually my old R500. I bought it back in 2015, as only the second owner. The original owner actually bought it at my dealership and serviced it there and our sister store religiously. I wasn't even in the market for an R-class but this one was so perfect I couldn't pass it up. What I really wanted was an ML55, but the only ones I could find were in terrible condition. So I settled for this.
And by settled I mean scored. Thing was nearly showroom perfect inside, easily no less than a 9/10 outside, and the best service history I've ever seen to this day. Of course I continued the service history tradition. Name a part and it's probably been replaced. I put this thing through it's paces over my 60k miles of ownership, and made sure it would keep on going.
I've road-tripped it, camped in it, quasi-off-roaded it, dailied it, overloaded it, and then some. I've done things that were never imagined with this car and it took everything in stride. Over the last few years I even lifted the suspension an inch and installed oversized AT tires, effectively giving it another inch of ground clearance for a total of two over stock
I've said it before and I'll say it again, the M113 engine is one of the most reliable there is. I don't care if we're talking Mercedes, Honda, Caterpillar, or even Pratt and Whitney. Doesn't matter. So I never expected, but secretly hoped, that this would need a new engine at some point. At which point I always said I would throw in an engine from an ML55 AMG (163, so 2000-2002ish).
But let me clarify something here, nether the ML55, nor my creation here, are the M113k kompressor/supercharged version like you may have seen floating around the internet smoking a Nissan while towing a trailer. Those are great, but slightly less reliable, considerably more expensive used, and would've required quite a bit of custom fabrication for all the extra plumbing and cooling required by the supercharger. So I kept it boring and opted for the ML55 engine (same as my old 210 E55, or a CLK55).
That's a plan I even mentioned here on oppo a while back, but didn't actually get much input on.
I nearly pulled the trigger on this back then, but got busy with other things and lazy with this. I had planned on just selling this as is, but I hate dealing with low ballers and before I knew it six months had gone by and I just needed to get rid of it. I half-ass mentioned the idea to @AestheticsInMotion when he was getting frustrated with the used Ranger market and he basically said "fuck it I'm in", so here we are! It was around that time I even removed the R from my oppo signature thing.
A few days later and I had a used 55 engine show up to my shop. Looked it over and made sure it was in decent shape, a whopping 20k fewer miles on it than the original engine. That following weekend I dove right in, transferring over R-specific and newer parts, and completely resealing the new engine (minus head gaskets because they never fail). Remember this post?
The partially disassembled engine on the floor is the new one. The one on the stand is the original. The other two are from/for the S63 AMG directly above. I didn't really keep track of the time I spent on this, but it was no more than a grand total of four days, maybe closer to three.
As the title says, the devil is in the details. I did everything I could to make this thing look like it came from the factory like this (think pre-kompressor S55 AMG). And I think it's good enough to confuse people who know this was never actually built by Mercedes. "R55 AMG" badges on the back. AMG air cleaner from a 2005 CLK55 complete with AMG engine builder's signature plaque, subtle metal AMG logo on the right side of the dash, and a tastefully modified exhaust system to make this vehicle sound more like a G55 than a luxury minivan. I believe the plan for this thing is to troll some car shows and hopefully find an R63 to park next to, so we'll see what people think at some point. But who cares, everyone who has seen it so far seems to love it, and most importantly it's new owner seems to love it.
Well anyways, that's the history, how about the details?
0-60 in 6.1-6.5 seconds
0-60 in 5.5-5.8 seconds (est.)
0-60 4.5-5.0 seconds
No it isn't blazing fast, but you have to remember this thing weighs over 5000lbs, and the torque feels fantastic. It's just stupid fun driving something this ridiculous around. Surprisingly, the initial torque-punch accelerating from a stop actually feels stronger than an R63. Presumably because the R63 engine prefers to be spun up before really making power, and the M113 power curve really kicks in at a much lower RPM than the M156.
Did I miss any details your were hoping to hear about? Let me know!
I can't wait to see all the shenanigans that AiM gets up to with this thing!
