g37 auto 5.5sec to 60, 13.9 1/4 miles, slk 350 manual 5.9sec to 60, 14.1 1/4 miles. (auto is slower, like 6.2sec)
you passed a g35..
I killed a G37, and confirmed the model when it passed me the second time (saw the badge). Frankly, I test-drove the G37 before I bought the SLK due to all the praise it received on edmunds.com and in various auto mags, and was not impressed, so I knew when it pulled up next to me that it would be an easy kill.
The G37 was supposed to be a 335i killer. I don't know who's driving these cars at the auto mags, but that wasn't my experience at all when I drove it. The TCU felt very similar to that in the Lexus IS300 (gutsy at lower speeds in the lower gears, and a bit over freeway speed, but noticeably less agressive in the upper two gears at over ~4.8-5k RPM and seems de-tuned at over 100mph) and 5th/6th were both so poorly matched to the diff that it felt gutless for the bottom quarter of the top two gears ("poor" only in the sense of track driving... for freeway driving, it's great because you get both power and economy). You can hammer these things at 80mph, and they'll get spunky until it shifts, at which point it feels like a Prius for a few seconds while you rev it back into its powerband. I think my girlfriend's comments after our few test-drives spoke volumes about that car ("It has a cool stereo"). A manual 335i would kill this car so easily I often wonder if the magazines received money to write the praise it got.
My opinion of the G37 was confirmed when I saw how it responded to being punched at 80mph (our speed). I gave him a full second at first because I knew from driving it that it was a Prius in lower 6th. Sure enough, he got up to about 100mph while I waited and then practically stalled, while I blew by still in 5th with about 800RPM left in it. When I shifted into 6th, he was starting to gain speed at a greater rate since his TCU was catching up, but it was too late - I was already at 100% torque and kept walking away easily, gaining length at a pretty consistent pace, with a good 2000 RPM left to work with, with all of that at insane torque and over 95% hp. I dropped out at a speed that I felt wwas getting dangerous (no need to endanger anyone on a public freeway), and the G37 was WAY behind us at that point, staying pretty steady behind us, but a good 5-8 car lengths at least and it wasn't going to catch up.
It helps to know how another car is going to shift, and how the TCU performs in the upper gears, if you're going to race an AT. I don't see how anyone could consider an auto tranny a serious track car when these TCUs are shipped from the factory to save gas and reduce emissions, NOT hammer down on that annoying dude in the SLK who just waved you on. There are exceptions of course (yes, the MB 7G is an impressive product), but generally speaking, an AT will never be as effective at keeping you "in the power" as an MT in the right hands.
0-60 and 1/4-mile times have absolutely NOTHING to do with how a car will perform on the street/track. Or, at least, extremely little.
Pro-street (or pro-stock) drag cars will do 0-60 in under 3 seconds, and a quarter mile in under 10 seconds (mid-9's are pretty average for pro-stock). Hell, when you're running a 5.29 gear ratio, that should be no problem, since you're not even shifting to hit 60. But they aren't built to run at peak power for longer than 15-20 secs.
The Ferrari F40, in comparison, does 0-60 in 4 seconds and a 12-second quarter mile. Do you honestly believe a pro-stock drag car would ever stand a chance against an F40 on any strip of pavement longer than a half mile? Perhaps you see the flaw in the logic now.
You wanna talk power, show the dynos and that speaks for itself. One of my biggest pet peeves is that all these manufacturers and magazines spouting 0-60s and quarter mile times don't EVER show you the dynos, which actually do mean something. Who cares if you can get to 60 in 3 seconds, if your power drops off at 4k RPM and your max speed is 90, and it takes 25 more seconds to get there.
And any decent driver, with knowledge of what a car's powerband looks like, can easily take advantage of that info to dominate cars they normally shouldn't be competitive with, especially if you're going by 0-60s and quarter-mile times.
I'm glad the G37 can get to 60 quickly. But it sure does have a hard time getting to 140. And let me tell ya, if I'm on a track with one, I won't be spending much time at 60. The G37 is a dog at 100+, and is really not much of a "sports" car. I'm sure it seems extremely impressive to people not used to driving 100+, though, and to drivers that won't be doing much more than spirited sprints to the grocery store.
And hey, if any G37 drivers are offended, just look at it this way... at least you have a really nice stereo to play with. My SLK's stereo totally sucks.
Something similar happened to me on our drive from NY to Florida this Thanksgiving trip, except it was a Mustang stuck to our tailpipe. I got up to 115 and he kept up with me. Slowed due to traffic and the speed alarm (my SO) was going off like crazy and punching me in the arm. The mustang kept on going. Luckily I slowed down because we both got pulled over. The officer said I was going 84 in a 70!
But he got the mustang for a lot more.
Yeah, thank god for the speed alarms. Heh heh. Mine has saved my butt many times. There's a reason I'm paying almost $400/mo for insurance, and my "speed alarm" has no issue reminding me of the fact. That, and she loves to remind me that if I get caught doing reckless speeds, they won't let me drive anymore. I really can't imagine any hell worse than looking at my SLK in the garage and then walking down to the bus stop for a ride to work.
PS - a stock Mustang, even a GT, is not competitive with the SLK. Certain Cobras and the 03/04-Mach1 would be, but none else. You gotta keep the contests to a minimum, so why waste it with granny cars? You may as well be racing those riced-out Civics, it's pretty much the same thing.
