Searching out historic performance data for my 2001 convertible, I found a site I link below that reports Car and Driver tested both the 2001 convertible and the 2001 Z06. Assuming this is not a typo, and that Car and Driver used the same testing protocol, the straight line performance of the two cars appears to be very close (4.5 of the convertible to the 4.3 of the Z06).

More interesting still, according to that site, the 2001 C5 convertible stacks up equally well to the 2005 C6 convertible tested years later.

It doesn't show what trans, tires and diff were tested. We don't know temperature or road conditions for each test.

The Z06 only had 55 more HP, a 16% increase but the LS6 cam and heads take mods well.

With an A4 trans and 3.15 gears the base can get a pretty good launch in competitive driving mode. The A4's first gear is lower than the M12 even if you factor the lower 3.42 rear gear of the Z. The auto shifts faster than a human being can. All this might be good for a few tenths of a second.

I read the tests as the convertibles (both the 2001 and 2005) and 2001 Z06 being manuals "6M". Not sure if the "run flats" of 2001 would give faster times than those used on 2005- or the rubber of the 2001, Z06.

After my posting, I'm more inclined to think the 2001 convertible Car and Driver tested might have been a ringer--- a bit quicker than the average car. Or perhaps because the LS1 develops it maximum horsepower and torque at a lower rpm than the Z06, 0-60 may just be a sweet spot. Anyway, I thought the data interesting- just wasn't sure if it was an accurate reflection of the real world performance.

The 2001 Z06 had a lower bump in power than the 2002-2004 Z06 as I recall. All C5s 2001 and later have the LS6 intake, so that closes the gap some.

I've owned both. 2000 Mag Red vert, and an '04Z. The vert was no slouch, but the Z was noticeable quicker in every aspect. Both cars were M6.

I've read 0-60times.com lots, which shows 4.0 for the 02Z, 4.4 for the base model. Other sites show 3.9 for the Z.
Never heard of the specs site

You may have nailed it- the performance gap between the '01 LS1 and '01 LS6 relatively small compared to later years. That may explain why when Car and Driver evaluated the 2002 Z06, the '02 Z06 was quicker than the 2001 Z06 (4 seconds compared to the previous year's 4.3 seconds).

Thank you!

The 2001 Z06 had a 385 bhp rating from the factory, 35 more hp than the coupe/vert had.

According to the dealer brochures for the 2001 cars, the following were the 0-60 times for the coupe/vert and the Z06:

coupe/vert: manual was 4.72 secs; auto was 5.05 secs
Z06: all manuals were 4.0 secs.

Depending on which testing organization you believe, the 0-60 times varied, sometimes by quite a bit.

I tend to believe what the factory released as the performance times.

I'm pretty sure there are OBD2 gadgets that will accurately allow you to measure 0-60 times via your smart phone. It seems like it would be hard to do with a stop watch. 4 seconds goes by quick.

I was thinking it said about the same in 2002, 4.7 for the coupe 6-speed, slower if an auto.
