Oh, sure, I like the show, but Clarkson seems to think that Europe is a country when he's talking about cars.
What I really watch it for is the list of lap times and how various cars stack up, although track conditions vary so much you can't put too much on it.

I would recommend looking at the file. I don't remember the triggers off hand, It is something like if the temperature is below freezing and the oil temp is below 100 then RPM is limited to say 4000. While you may call that inconvenient, it saves your engine from the most damaging actions a driver can take. It helps protect GM from paying warrantee claims for drivers doing really stupid things.
Correction: I went to the file and checked. The actual parameters are: coolant temperature and engine run time. They cutoff RPM varies by temperature and time.

Can you point me to a link where it discussed actual fuel cut off at a lower RPM when cold/etc.
Thanks,

Download the program. Go to your my Documents>HP Tuners>Logs and Tunes>Samples and select the 2014 Corvette file. When it opens instead of putting in an activation code use Demo mode.
Go to Engine> Fuel> Cutoff, DFCO it has a Startup Modifiers section, click on Cold Engine and it has parameters.
Look at that an tell me your interpretation of what is there.
I am sure you have to be in the Advanced mode to see all the parameters.
It looks at the coolant temperature and Engine run time. not oil temp as I said previously. So at -40f and run time up to 60 seconds the fuel cutoff is 4600 RPM. Different temperatures cause different delays, and cutoff RPMs before full RPM is available.

it is not a discussion, but actually reviewing the HP Tuners file for the stock parameters for the C7.

What can I say. I'm tired of seeing the same people crapping on the car and not moving on with their lives, and instead trying to make things so negative here in the C7 section.

My M3 and M5 also did this when the engine was cold. It only lasted a few minutes and by the time I was out of my neighborhood it was "warm enough" where the RPM's were back up to normal.

Electronics can be turned off for bench racers wanting to feel cool or for the pros who actually know what they are doing.

2020 C8 of the Year Finalist - Unmodified
What the Brits love is hanging out the tail and lots of tire smoke. The reviewers generally love manual boxes and good creature comfort/controls.
I think the looks are really "American" and that will be a knock, as well as the black grills and targa looking out of the 80's. But, in general, I think they will like it for what it does and love it's price.

My 2004 E46 M3 lowers the yellow/red rpm range on the rpm indicator when it is cold, and moves up as the oil warms, but it does not change the limiter (fuel cut-off) from its normal value as what is being suggested the C7 does in this discussion. That would be a nice feature to help protect the engine if true.

There's stacks of grip at both ends, the adjustable steering communicates really well when you want it to and fades away when you don't, the chassis absorbs changes of input from the road and driver without issue. And, best of all, it's all massively entertaining in the process. Unlike a lot of high performance cars which don't give you much feedback until the limit, you really feel like you can thrash the C7 and get all the value out of it at all speeds.
So should I buy one then?
If you've ever thought about a 'Vette, now is the time. By thoroughly updating the car the C7 team have vaulted to the front of the wave of modern two-seater sportscars. There really isn't anything else on the market that does as much as this car can do for even twice the price.
Car still keeps getting positive reviews....
I have to drive one .... especially the auto.
But in the end I believe it's all just a setup for the big fail on the show.
And, that makes for good car show entertainment.

"When the engine is cold, the M3's engine computer automatically lowers the redline (and the rev limiter) to 6500 RPM"

That C7 article was written by TopGear's L.A. editor, Pat Devereux. Bear in mind that British roads are often quite different from those chosen by manufacturers for media events in America, though I think the improvements to the C7's handling and suspension should reap benefits for the Brits. As for style, the TG television presenters generally don't have a problem with the style of American cars. Clarkson lusted after the Ford GT and Hammond is a big-time musclecar fan (owns a classic Mustang and Charger, last I heard).

Any idiot that does that shouldn't own any motorized vehicle, let along a Vette.
