The recent motor trend test: 0-60 3.7sec., Q-mile 12.0@118.4

What would you attribute as the reason for the 12.4-12.5 runs? I guess it can be a variety of factors, temperature, altitude, driver skill. I'd like to see a C7 and C6 run on the same track on the same day. Hopefully it happens soon. I think C7 comes out ahead but maybe not by as much as I thought earlier.

The C6 has had years to extract the best times possible, the C7 is just getting started, also Edmunds got 12.0 Q-mile and Hot Rod reported a 12.12@119 when corrected for weather.

The 911 numbers are pretty consistent with most other test on the car. I don't buy that the C7 is that slow except in very poor conditions. A LS3 is quite a bit faster than their times in trap speed and 0-100.

Except for Hennessy's car, whose driver is a strip veteran running on a prepped track , all the others have run remarkablly close to 12.4/116. which, given weight and power, is pretty much the result we should be seeing. A base model LS3 with NPP would only have a 2% disadvantage. What surpises me is that the 911 starts pulling away at the 1-100.

But no matter. It's a total massacre on a track and that's what counts.

The 2010 GS tested by Car & Driver weighed 83 LBS less than the C7. The 1/4 mile for the GS was 12.6 @ 115 vs. 12.5 @ 116. LB per HP is
7.7 for the GS vs. 7.5 for the C7.

I would say the results from Car & Driver are in the ballpark.

if your premise were correct the C7 would be way ahead of the 911S, there are many more factors at play than just pounds per peak HP.

Wait a minute...

Reminds me of recent road tests between BMW 335/535 and Lexus IS/GS 350. This is a new world we're living in!

Awesome win for the C7!! :thumbs:

Really?

This is exactly what I find annoying about the car mags. Its one thing to provide basic 0-60, 1/4 mile for reference but track times are not much value to 99.9% of us.

If the C7 goes around Laguna Seca 2 seconds faster than 911, what does that tell me about my drive from Tampa to Miami? I'll give you the answer: Nothing!

Even people who track their cars, and they are few and far between in the total scope of sports cars, aren't actually racing. Those actually racing are tiny percentage of a tiny percentage.

I can think of hundred more important questions than lap times at Laguna Seca and what Randy thought of the car at 10/10s in turn 1.

How are the seats? Are they comfortable after an hour? How's the infotainment system? Can I plug in Android or Iphone? If I'm driving on a back road and crest a small dip that unloads the outside wheel, what does the car feel like? Any klunks or sticktion to the trans, rear end, brakes? Cupholders get in the way of the gearshift or nav screen? Are they deep enough to not tip the cup or can going around turns?
When pulling away from a light how fast am I going if I red line first gear? Second gear?

I hate to say it but I'm liking reviews on CNET more because they are more real world. Even Top Gear and Motorweek give a better feel for the car than the car mags are doing.

I suppose that's part of the reason they offer a years subscription for $8 and keep sending issues even after the subscription ends.

Great win for the Corvette. I would choose the C7 over the 911 even if the prices were switched.

I don't get the 0-150 though....something doesn't make sense. Gear changes don't matter as much in triple digit speeds I would suspect. The Corvette should walk the 911 after 100 mph imo.

Corvette vs. 911 S:

0-60: 4.0 vs. 4.0
0-100: 9.2 vs. 9.3
0-150: 23.2 vs. 22.8
1/4 mile: 12.5 @ 116 vs. 12.4 @ 116
Braking 70-0: 142 vs. 147

Overall Points: 207 vs. 202

1.6 mile Streets of Willow track: The Corvette is 2.1 seconds quicker than the 911 S. That is a massive difference.

In the "as tested price" category, the Corvette received 20 points (max), while the Porsche received 1. In the "rear seat space" category, the Corvette received zero (obviously), and the Porsche received 5 (max).

If you take those two categories out, the score is 187 vs. 196. However, and I quote directly from the article, "before you start howling that the Corvette won solely on price, notice that in the stuff that matters to sports car buyers, chassis and powertrain, the Porsche holds a single point lead. Is such a minute edge worth $50,000? $80,000? The Corvette does not win on Dollars. It wins on sense".

No skidpad or slalom testing?

I will like to see the complete scorecard in the different categories.

2.1 Sec difference in lap time is huge. MT Laguna Seca lap times were much closer.

P...D...K... :D

Simply a stellar transmission for acceleration.

I believe many people, enthusiasts in particular, buy sports cars based on the car's performance abilities... even if they don't always use the potential. A track time is the best measure of a car's OVERALL capability as it takes into account power, handling, braking, balance, etc.

When a magazine reviews a luxury car, they don't test track times. When they review a sports car they do. When I buy a sports car, I'd like to understand what the features and amenities are (as you note) but I buy it based on its look and performance. That's just me.

2.1 second lead on the road course says it all.

In a recent interview, the Corvette CE said that he wants to take weight out of the C7. Like any GOOD CE, he's constantly looking to improve the product. The 146lb difference in weight between the C7 and the 911 is a BIG factor in the performance difference. Perhaps the coming C7 models will include some weight reduction or some of the vendors will be working the weight reduction area. :cheers:

Why? How do lap times recorded on a smooth dry track where a professional driver has practiced many times and knows all the braking points and lines and who is capable of achieving the car's maximum potential while having runoff areas in case he makes a mistake or spins out translate to real world roads with unknown traction, unknown braking points, unknown lines, and unknown traffic hazards with little to no runoff safety areas??

What I don 't get is they are testing a preproduction C7 without MRC.... Against a 911S with $48 k in options... And the Never state what the options are ... Is so bogus....

I agree, and that has been covered. The trap speed should tell the story though of real world roll-on acceleration. I'm confident that a year from now when there have been a lot of tests and talented drivers taking them to the strip we will be much happier with the overall results.
