C7 Corvette

[SVT_Power]

Even street cars are towed to & from the track. Most guys don't wanna be left stranded if they break something, plus then they can bring more tools and equipment.

Again, if I was shopping for a sports car, track prowess wouldn't be at the top of my shopping criteria 

Just thinking about what those would be, I think top 3 for me would be

1. How much do I like it
2. How does it look
3. How does it drive (I think this is almost a moot point since at that price point/class of cars, the baseline of how something drives is so much better than average already anyway)

Towing your car to the track is for bitches.

Well, it does suck to shove your only way home into a wall...

Taxi/Uber/ambulance/how don't u have any buddies at the track that can give u a ride?

Or just AAA it....

Then you can't fake an accident and make insurance pay for the bodywork

Surprised I haven't seen this posted yet (unless I missed it earlier). Watched it today. Was an interesting watch...surprised how expensive this Corvette is though.

The "street spec" GS is $65K if youre ok with the "base" interior.

That 911 is ridiculously fast for how much power it supposedly makes.

I feel like cars (or really engines) are so powerful today that speed is as much about having a chassis that can effectively apply that power as having a powerful engine itself.

Probably true today(or the last few years), but germans have consistently done more with less power for a long time. I think just better components and more time spent fine tuning is what gets them there.

It all adds up

959 did 0-60 in 3.6... but while this has less HP and only RWD, it has way bigger + more modern tires, PDK, launch control, longer wheelbase (smoother weight transfer), less weight. It's the perfect storm for getting out of the hole with 2 drive wheels

It also traps significantly higher than the more-powerful Corvette -- 120 vs 116 mph.  I think the Germans are sandbagging it with their power ratings, especially for turbocharged engines.

Gearing and shift speed play a huge part.  The PDK shifts far faster than a human rowing a stick, which means that the pauses (in which the car is coasting rather than accelerating) are shorter.  All things being equal, the car that shifts faster will have both quicker times and higher trap speeds.  If the 911 had had a traditional MT, it would have been a much closer race.

[12,000 RPM]

It puts down about what you'd expect for its power rating (369WHP... ~13% loss)

911s just put the power down. And the PDK keeps it coming fast. I think I would still choose the 7MT though.

Fairly certain the base 911 with 7MT traps @ 117mph.  Per Motortrend

And the new one makes about 380whp.  369 was the old model, but still about what we'd expect.  I'm actually pretty surprised they picked up 30whp on the old engine with a 93 tune.

[GoCougs]

PDK what with launch control and quick shifts is probably worth 0.5 sec in the 1/4 mile. The 911 is also rear engine which helps launches. In a drag race a lot is decided in that first 60 feet.

The Grand Sport traps low because it's packing the Z06 Stage II aero package without any more power than the Base Corvette.  The Z06 Zero package is ridiculously aggressive and the reason why even the Z06 doesn't trap nearly as well as it should despite 650 HP.

Also the PDK shifts faster and stays on boost compared to a manual.

In base form and with an auto, the Corvette will trap 119, even in convertible form

Kind of crazy that these things will go from 0 to double the speed limit in the distance between like 2 traffic lights. A couple MPH here or there is purely academic

Yeah maybe I am just getting old, but to me the HP race is over. You can get a car with more than enough power to go ridiculously fast in just about any segment. In the sports/performance car category the power figures are amazing. I am mean a ~35k Mustang or ~40k Camaro are so far beyond what any normal person could safely use on the road.

Maybe when I am older and rich I will be able to buy one of these cars just for track use. that would be pretty fun.

[12,000 RPM]

Vette is about as fast as my bike (same 1/4.... bike is faster out of the hole but Vette traps 12 MPH higher) so this level of performance is just right. I wouldn't be topping these things out but there's nothing quite like a quick throttle squirt in top gear giving you a 15-20 MPH jump. This level of performance allows you to be really lazy and still cover ground and space assertively

[12,000 RPM]

I wonder if the Vette is going to get the 10 speed they are putting in the ZL1

That might put the 7MT to sleep

Enough aero to materially affect trap speed will also affect ET, and the GS ran a 12.2, which based on a healthy sampling of M/T C7 road tests, is right in line with non-GS C7s (averaging 12.2 @ 117). 8sp C7s are quicker than their M/T counterparts so that's not an apt comparison.

The M/T C7 Z06 is relatively slow in the 1/4 mile (~11.5 @ 125) because of hugely tall gearing (66 mph in 1st, 93 mph in 2nd, 124 mph in 3rd). The 8sp C7 Z06 is significantly quicker (~11.0 @ 128) primarily because it has far more aggressive gearing (45 mph in 1st, 71 mph in 2nd, 102 mph in 3rd, 126 mph in 4th), so much so it has an entire extra gear to exploit during its trip down the strip.

[giant_mtb]

66mph in first?  Sweet baby Jesus on a candle stick.

[CaminoRacer]

I think my dad's Camaro gets to 60 in first with similar power. That's with a 6500 redline, not sure what the Vette's is

Yes the Auto Corvette is faster than the Manual, that's why it's a more apt comparison to a PDK 911 S.

Basically he was asking why the 911 trapped so much higher than the GS with less power.  Part of it is the Auto vs manual and the other part is the aero.


The Stage II aero package definitely shaves a mph or 2 off the top.  Since the difference is mostly in the last few moments of the run, the change in ET is minimal.

Look at the base C7 vette 7M

vs the GS

http://www.caranddriver.com/reviews/2017-chevrolet-corvette-grand-sport-manual-test-review

The GS nips the base Corvette by a 10th to 60mph, due to larger stickier tires. 
They tie in the ET, but the base C7 is traveling just a bit quicker.

Then the C7 just murders the GS from then on out.
C7 0-150:  20.7 sec
GS 0-150: 24.1 sec

In more detail it looks like the C7 and are neck and neck till 100mph, building it's lead faster as speeds increase

            C7                GS                Diff
0-70     4.8               4.7                -0.1
0-80     6.0               6.1                +0.1
0-90     7.2               7.3                +0.1
0-100   8.6               8.7                +0.1
0-110   10.5             10.8              +0.3
0-120   12.5             12.9              +0.4 (1/4 Mile happens somewhere around here)               
0-130   14.7             15.5              +0.8
0-150   20.9             24.1              +3.2 (C7 murders the GS from 130-150, as expected with aerodynamic drag being the square of speed)

The C7 GS/Z06neeeds some type of retractable Aero instead of that fixed rear spoiler.

I agree. I opted out of the fixed rear spoiler on my V' for the same reason.
