R&T c6 test: 13.2@107mph 1/4 mile

http://www.z06vette.com/forums/showthread.php?t=64904

Anyone seen this R&T article? It was a droptop, but the time is too slow and the mph too low for a 400hp sub-32XX car.

Puhleeez! :rolleyes:

Looking at the other thread of the MT test, seems the z06 guys were a little worried that a cheaper, base c6 would perform better than their more expensive c5 z06's. Guy starts thread with "all of us can breath a little easier" heeh.

Agreed...I sense a little nervousness on that site. I don't think that an '02+ Z06 has much to worry about from an LS2 vert Vette, but I think the Z51 would make a damned good race. With that said...107mph is pretty sad (crappy rag time or not).

WTF?!?! Did they make sure all the cylinders were firing?? Was the track made of greasey pizza?? Did they have it in sport mode (or whatever it is)?? Was a 400 lbs quadrapalegic driving??

I'm disgusted.

Someone gave them a C5 with a HID conversion, and thought it was funny.

Nah, conditions were terrible. Wet track, hot, lots of humidity.

Still, they suck at driving. When stock my SS trapped 108.

Road & Track sucks at 1/4 mile tests. Subtract a full second off that time, and that is what the car is capable of.

Maybe they ran it in reverse? :think:

SO whaddaya we got so far?

MT 12.7@112
C&D 12.7@113
R&T 13.2@107

So the car's a little slower than the C5 Z06 and a little faster than a Cobra. It's weird though. Maybe it's that drive by wire TB. The '04 F150 guys say theirs actually introduces a serious throttle lag.


This Jrod fella seems to have inside info. And it looks like the next Z06 gets a hand built 6.4L motor making 500hp. That's pretty good.

Apparently you can preview the next Z06 motor in a GTO.

GM Performance Division at the Woodward Dream Cruise
Andrew Charles
AutoReport

GM Performance Division will unveil two new concept vehicles for the Woodward Dream Cruise next week: a modified Pontiac GTO and Chevy Colorado pickup. The modified GTO and Colorado are "Employee Enthusiasm" vehicles, an internal volunteer program that gives younger GM engineers the opportunity to manage a concept car from start to finish. The first public showing for the vehicles will be at a Woodward Dream Cruise press conference Tuesday, Aug. 17 at Pioneer Park in Royal Oak. They will then be on display at Athens Coney Island throughout the Cruise.
The GTO concept has a 6.3 L V8 engine with 500 hp at 5200 rpm and 500 lb-ft of torque at 5000 rpm, matching early rumors about the LS7 for the C6 Corvette Z06. It also has a six-speed manual transmission, modified brakes, bigger wheels and tires and new exhaust. The bright orange exterior features a new hood, fender, quarter panel, spoiler, front and rear fascia and rockers.

The Chevy Colorado concept has a 6.2 L engine that makes 420 hp at 5600 rpm and 420 lb-ft of torque at 4600 rpm, sure to fuel speculation about a V8-engined Colorado. The wheels and tires, brakes, suspension and exhaust systems have been modified, and the exterior has new front fascias, front and rear wheel flares, hood, modified rockers and custom side mirrors.

The C5 was drive by wire too. R&T almost always has the slowest times of the big car magazines (but the best photo spreads and data sheets). I wouldn't sweat it. People will be getting mid 12s out of them all day long; just a bit behind a C5 Z06. :)

Yeah a few will. But it looks like with a good driver it's a 12.7 car. Which isn't bad, but I was expecting more.

12.7's with at good driver :confused: If you can't put the thing to 12.5's with 113mph and tons of usable torque, you can't drive...

My bet is that a good driver will be able to hit the 12.3 range.

That being the case, my next thought is "what does Hill have up his sleeve for this car next year"?

I think the car could do with a bit more cam, especially on the duration end. I think that would bump power considerably without requiring sodium filled valves and special springs.

When Z06 hits, there is going to be a lot of headroom created for the non-Z06 cars to increase power. 425hp? 450hp? I don't think either of those numbers are a huge stretch for this motor, and the marketing angle may be to protect the 2004's (especially the Z06's) by keeping the new car slightly slower for the first year.

Low to mid-12s is what these magazines got with a C5 Z06, yet GMHTP got a '04 Z06 in the 11s. I firmly believe in the right hands a C6 will go really low 12s.

I dunno. Something just doesn't add up. Either the tuning is pulling back(non-shift torque management?), the drive-by-wire is throttling back, or whatever. But a 3100lb with 400+hp and torque curve wide as Nebraska should be running in the 116-119 mph range. There's something wrong.

When that first quarter mile test came out by Motortrend, every bowtie head was saying they can't drive. Well C&D backs it up with the identical time. They have decent drivers. Yeah they don't powershift or feather the clutch, but they are above average drivers.

Something is still locked up in that PCM. Cuz the dynos don't lie. The motor should have the C6 breathing up a Viper's tailpipe, but it's not even close. Not even to the old the 450hp GTS.



BTW did everyone just miss that the Z06 LS7 is being shown off in a GTO tomorrow in some park? Is that in Detroit? Is someone going to go see it?

I think Evan from GMHTP will get the C6 into the 11s.

Again, the Road and Track test was run on a freshly wet-down track. Read the article.

Quote from the R&T article:

"Although our test numbers show the Corvette convertible is only marginally faster than the 50th Anniversary C5 coupe we tested in 2002 (4.8 sec. vs. 4.9 sec. 0-60), it's not really an accurate representation of the two generations. The convertible, which weighs more, was tested under less than ideal conditions in nearly 90-degree heat and high humidity on a green track that had been recently soaked in a storm. In the quarter mile, the open car posted a 13.2-sec. run at 107.9 mph, again slightly better than the C5's 13.4 sec. at 107.5 mph."

Yeah I heard you the first time. I'm not commenting on the 13.2@107. I'm talking about the 12.7@112-113 that's been backed up twice by 2 independent sources. That is not much for a 400+hp 3100 lb car shaped like a missile. The Cobra and Z06 guys are laughing at the C6.

Besides, the Cobra was antiquated next to a C5. A C6 is in another league altogether. :)

Seriously...what did your beloved Cobra run with these rags?

Oh...here's one from R&T on the 2004 Cobra:

The supercharged V-8 has a wide, readily accessible powerband that makes 2nd, 3rd or even 4th the right gear for a variety of situations. The 390 lb.-ft. of torque propelled the car to 60 mph in 5.0 seconds in our track testing and helped dust the quarter mile in 13.4 sec. at 107.0 mph.

man...that's cookin :rolleyes:

Try getting ALL the FACTS.

Here's the best run for an '03 Cobra by C&D.

In terms of power delivery, shift quality, steering feel, and noise levels, the '03 Mustang Cobra offers quite tolerable levels of comfort—particularly in comparison with the Cobra R, whose performance it now so closely matches. (The '03's 12.9-second quarter-mile at 111 mph is actually 0.1 second quicker.)

I agree, I just picked up the new R&T and it features 6 cut-away illustrations on the C6. There C6 articles are by far the most in depth of the magazines. Motor Tends road test of the C6 was flat out vague, Car & Driver was a little better but not by much. Recently Motor Trend tested the Cadillac STS and there wasn't even a photo of the back of the car.

I don't have a subcription to R&T but I am seriously considering canceling another magazine and getting R&T because I like there larger format, full page photos, more technical articles. But they do have a few drawbacks like the discussed performance #s they get, and also I don't care for half the magazine being dedicated to "Track" (racing)

While the Z06 times in the magazines were consistently faster than that (though 114 mph was common too), I don't recall the big 3 (C&D, MT, R&T) car magazines beating a 12.7@113 in a stock Cobra. Besides, the Cobra was antiquated next to a C5. A C6 is in another league altogether. :)


Never said they beat the time. But it's a drivers race between a discontinued, fat car from Ford(12.9@111) and GM's all new world beater sports car(12.7@113) with the all new world beater 400hp LS2. If all I had to do was drop a $25 pulley in to waste the new C6, I'd be laughing too.

And the Z06 owners are smug knowing the C6 is still the second rate vette.

Yes the C5 and C6 are better cars than the Cobra.

Modding a car throws everything out the window...

...R&T almost always has the slowest times of the big car magazines...

I've noticed that too. I seem to recall that when the '93 LT1 F-bodies came out, R&T was only getting mid to high 14's out of them. But they did get them to go up to a 160mph top speed (est.) :rolleyes:

Every race is a driver's race. I've never had much more than an academic interest in drag racing, particularly with street cars. 12.9 vs. 12.7 is a 2 car length asswhooping. Live by the magazine, die by the magazine.

Now what interest and expectation one may have from a car is fine, dandy, and valid on it's own. What you like and prefer is your own business, pure and simple.

All around performance wise, the 'vette hands the Mustang it's $ss. If this comes as some revelation, you've just landed from an isolated sector of he universe.

As a Z06 owner, I am neither relieved nor distressed by the C6. Having driven both the Z06 and the Z51 C6, I can tell you that it's close. The Z06 is still the stronger track car, no question. The LS2 is very fat in the torque curve under 4k RPM and the Z51 IS the one to have right now for a new owner.

The next gen Z06 is more than stout. Any such comparisons will not be close. Quote me on this if you like.

Another slow magazine time for the C6: Automobile Magazine tested 1/4 mile 13.2 @ 112 mph.

Coupe or convertible? 112mph traps show some definite 12 sec potential, but still some ways from the 405hp z06's 114-116mph traps.

Looking forward to seeing how they'll do in the hands of the public and enthusiast mags.

Well that's just what it is. A high 12 sec car running about 112-113mph in the quarter. A definite step up from the C5 coupe.
