>implying you can prove otherwise
how assmad will you be if it does?
>>
>>14275859
It is.
And it's very good. Take a look at modern mpg on the non z06 c7 along with its power. Getting 28 on the highway with a 500 hp car is impressive, as edgy and third world you wanna be

Chevy is killing it with the new Camaro and Corvette, all of the new tech they are bringing to the table is fucking nice. I'm really excited to see how their new transmission turns out in the coming years.

When people say automatics are better than manuals, this and Porche's are the ones they are referring to whether they know it or not

we are not talking about ecoboxes here

did you not read the article? gm said that the motor put out too much torque to use a dual clutch. that motor has power to spare.

also

also

>>
>>14276875
>same as the koenigsegg regera
Are you sure about that?
>>
>>14276943
yeah I thought the Regera didn't have a transmission
>>
>>14276947
>>14276943
it has a torque converter (fluid coupling)
>>
>>14276953
Really? Because I was under the impression it had a direct electric drive? That was the whole hype about the Regera.
>>14276947
Yeah, this.
>>
>>14277006
still needs a way to disconnect drive you fuckwit
>>
Nice picture of a manual transmission bro. Do you not see the gear forks in there?
>>
>>14275859

Pretty irrelevant as no one with a brain would buy an automatic Corvette or Porsche
>>
>>14276827
It has wheels and pistons just like your shitbox. You wanna bitch about that too?

>>14278411
Came to post this. It must be how they get the transmission noise in the cabin.
>>
>>14275876
no it isn't. Well if it was getting 28 mpg while making 500hp that would be.. but when the car is getting 28 mpg is making a very small fraction of 500hp.

The fact that it shifts faster than the PDK is impressive if that is indeed true.. and that transmission is as durable as the PDK, which remains to be seen. The endurance of the c7 has yet to be proven in anyway.
>>
>>14278454

Gear whine enhancer unit
>>
>>14278551

No fucking car gets their advertised MPG at their advertised top HP. What a retarded statement to make.

Why would they? It makes no sense, they gauge MPG based on average speed limits/average driving conditions, someone isn't going to be utilizing 500HP while daily driving.
>>
>>14278658
my point was that 28 mpg highway for a very aerodynamic 2 seater isn't anything even remotely impressive.

> someone isn't going to be utilizing 500HP while daily driving
are you sure you belong here.
>>
Automatics/dsg or whatever are fine in the race application. Removes human error as shifts faster. Sure manuals are more fun. But at the end of the day it's all about the track times.
>>
>>14276827
>it has a steering wheel

Stronger
lighter
shifts faster
smaller
cheaper to build

Are you fucking kidding me, nigger?
>>
>>14276839
>clutch
I dont care if a senile old man is controlling it. I would take that over fluid coupling any day
>>
>>14276940
clutch lock up on a torque converter ONLY happens at a constant speed without a load, and its for fuel economy.

>gm said that the motor put out too much torque to use a dual clutch.
fucking Bugatti managed to do this 15 fucking years ago on a 1000 torque car. What the fuck GM?
>>
The big difference between Corvettes and most of it's competitors is people actually put real mileage on them. Dry DCTs are terrible and last 5k miles at best if you really hammer the cars. Wet DCTs can't be worked on and have to be sent out if something goes wrong. I work on and drive DCT cars all day, I would never get one in any car that I planned on driving more than 1k miles a year.
>>
>>14279240

consider the fact that a lot of manufacturers are putting DCT in even their lowest model range (Acura), you are just being a GM faggot with that bullshit statement.

nope.avi
>>
>>14279240
when you say most of its competitors, i'm assuming you excluded porsche and their PDK, as I haven't heard (first person) of any issues and the folks i know track their cars.
>>
>>14279268

fat matt farah mentioned in one of his videos that the C7 auto is no where near as good as the PDK too.

ib4 "oh fuck that fat fuck, he's shit"
>>
>>14275876
But that's because of tall overdrive gears and v8 torque, not a fancy transmission.

no one mentioned the c7 8speed being "better" here you fucking retard.
>>
>>14275859
Is this the 8sp ZF box or some GM part?
>>
>>14281077

in-house built by GM, according to that article.

>That new ‘8L90’ transmission, designed completely within GM, by a dedicated team, is a traditional hydraulic automatic—solenoids, valves, planetary gearsets and all—but GM says that it provides the super-quick shifts of dual-clutch boxes, yet with more smoothness.
>>
>>14281268
Shoulda just sourced the ZF box.
