2005 LS2 A4 80k miles Base model

Online it says 4.2 seconds 0-60

Whats a real world number?

Assume tires hook perfectly and no mechanical issues with the car and near sea level in say ~50 degree weather.

Is 4.2 a real expectation?

Also, would 80k miles have any negative effect on horsepower? If so, how? Consider all normal maintenance is done and car is not neglected.


UPDATE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!

I was waiting till it was cold to do an actual test, but I couldn't wait, I'll retest again once ~50-60 degrees

98 degrees F
~600 feet altitude

0-60 ran 4.22 seconds!!!

I was shocked!!!! especially because of the heat I was expecting more of something like 4.8

Car is base model with a vararam intake

Another question though, do I start the time when the speedometer starts to go up? Or do I start the time when the RPM shoots up from flooring it?
Idles ~600RPM or whatever stock is, then it goes to probably 1800 RPM WOT before the speedometer even starts to move. This is all shot from a high high speed camera, so I wasn't sure in terms of actual acceleration since I only recorded the gauge I have no idea when the car actually started moving and I'm not sure if the speedometer just lags a bit

4.22 seconds from the moment my RPM starts to go up,
4.07 seconds from when the speedometer starts to go up

I've done 4.2 exactly in mine as the best time with long tubes, CAI, and tune. Car was 125k at the time so the mileage shouldn't effect it.

I'm trying to figure out why any of his matters to you?? "220 221 whatever it takes"

And I'm trying to figure out why you have to know why...guy asks a question, he has his reasons, either answer it or move on.

Why does his reasoning matter to you? What purpose would it serve for you to know? Either you know the answer or you don't; it was a pretty simple question.

I see it's going to be one of "those" kind of mornings... I need another coffee... ...WW

WOW! Relax Francis. I was simply wondering why 4.2, 4.3 or 4.1 makes any difference to him. I appreciate the knowledge and life lessons of the senior C6 members here but to ask a pointless question like he did without a little back ground info puzzled me.

4.2 is probably very accurate. It's not really fast by today's standards, but not bad. I would expect that it may even be slightly better then that at times as well.

Corvette_Ed

It's a performance-related question. Logic would dictate that he's concerned about the performance of his car and/or driving skills. Either way, it really doesn't matter.

I think you've grown accustomed to speed my friend lol.

4.2 is fast in my book, really fast! Sub 4 second cars are ludicrous speed IMO. A lot of fun though if you can handle it

jaredtxrx

4.2 is your number. A lot of those tests are done over and over and magazines take the best time to publish.
You "assume" the tires hook perfect and no mechanical issues, near sea level and 50*. You kinda throw "Real world" out the window when you get these parameters.
Now one place I go to for a more "Average Joe" type number is Motorweek. They tend to be the slowest of the major publishers. They say 4.8 seconds 0-60. This is probably closer to what you'll see people achieve on a non-prepped surface and giving it a random go from a stop light.

I think it was a good question, I've always wondered what the "real world" 0-60 time was. I know the book says 4.2 seconds and I use that time to compare my "lowly" LS2 to newer, faster and more powerful cars coming out, kinda like knowing where you rank on the food chain. My old '11 Hyundai Sonata with the Turbo 4 cyl. and 270 something HP supposedly did 0-60 in 6.2, I always thought that was incredibly fast (comparing to my C6) for a full size 4 dr. sedan. The one post above says 4.8 so I guess I'm somewhere in the middle, still very respectable for a for an older sports car. All good Buddy, have a great weekend!

Not sure if you're talking bone stock or modified, but my 0-60 time on this pass was 2.195 seconds according to my HP Tuners scan:



It was even faster on this pass, but I forgot to record the run:

I think on a good day, on a good road, probably with a little practice, 4.2 is achievable, maybe even quicker. But just to go out with no prep and no practice, I would say closer to 4.5, with a stock car. Still very respectable for today's standards.

LoganExplosion

Lots of variables to give an exact number. But I think 4.2 is the ballpark. Mileage shouldn't matter too much. I think conditions and traction matter the most for 0 to anything. Anything under 5seconds to 60 and you're blowing past most cars on the road. http://www.zeroto60times.com/ has some good comparisons.

HOXXOH

GM advertising specs were 4.5 for 0-60. but didn't state if it was A4 or M6. MT tested an A4 vert with a 4.8 for the 0-60. GM's 1/4 mile specs were 12.9 to the MT test of 13.1.
For real world comparison, you can look for '05 A4 results on the Showroom Stock LS2 performance list. https://www.corvetteforum.com/forums...challenge.html

Answers like that will get you sprayed, with RAID.

......... at our house the best example of a car in this range is a 2014 Mustang. Ford claims is good for 4.3 Seconds 0-60.

The car has this cool little "trak app" feature that will measure your 0-60 automatically from a standing start. I've personally only tried it out a couple of times and never could do any better than a 4.7 sec........my husband has the best recorded time at 4.4 seconds........but he did that after swapping out the skinny 255 perelli tires for something wider......that still wheel spins pretty heavy.

Leaves me believing the car could make the 4.3 to 60 very easily on slicks and I'm guessing that's how it was done for the Ford time......that or a really sticky surface at the track and a near perfect launch.

No reason to believe a Chevrolet time would be any less in need of the perfect launch to meet their advertised times in a Corvette.

The faster they make these cars......the less forgiving of anything less than a perfect run they are.

If really consistent is that important ........maybe it's time to ditch the RWD Corvette and just buy something AWD.



The car has the potential

Patsgarage

Best answer yet. No street surface will provide close to the grip that a track will, any mfr time is set under perfect conditions. As Krystal said, the only thing that would possibly match it's best 0-60 time on the street is an AWD car.

BlindSpot

4.0 sec. becomes a threshold to me. once you get below this, you start leaving the old style RWD platforms at any HP. Here is a list of the fastest 0-60 times tested. Look at how many on this list are AWD. Imagine if the C8 came out with a 900hp, mid-engined, AWD platform!
