That's a good photo, too.

Thanks. Bokeh effect on the s10 and contrast enhancement

It has eyes.

Yep!

It does have a Decepticon-like appearance, for sure.

Correct. Mean, not pretty.

Also known as an automatic.

From the Autoweek write up. Very clear DCT is not an Automatic. Even has a clutch function with the paddles. Just no pedal. That you choose to believe a regurgitated press release from a marketing company that would not know the difference or the most respected Completion journal that actually took the time to vet everything out. So just admit it...your wrong. Here is that section.

The Dual-Clutch Transmission

That’s only a dual-clutch transmission. No conventional clutch-pedal or torque-converter automatic. The C8 Corvette’s DCT has eight forward gears and wet clutches. Juechter calls it “the crux of the car” and notes that his team wasn’t too impressed with dual-clutches that were already out there.

“Finding a transmission that would do all of the things we want it to do—fit in this package, handle our torque—was a challenge,” he says. “We ended up designing our own, from scratch. Custom for our engine. There's a whole bunch of requirements that we put around the transmission.”

Juechter’s team wanted a wide latitude of adjustment in shift control strategy, lightning quick shifts when they’re necessary and torque-converter smoothness when that’s preferred. This C8 DCT accommodates some complex algorithms to change auto-shift patterns over a broad envelope. Perhaps best of all, a double-paddle de-clutch feature allows the driver to disconnect the clutch by holding both paddles. That should allow more manual control and maybe something more like a clutch pedal.

The DCT will be built by Tremec in a shop near GM’s Performance Build Center in Wixom, Michigan.

What you mean is that it doesn't have a torque converter.

It is an automatic. It shifts on its own, it's an automatic. That really should be the end of the argument, but if you want to keep going, you can.

I’ve discovered a new word - manumatic.

Is that an automatic for real men ?

I've held these beliefs long before I joined WUS or Twitter. Maybe I was being hyperbolic, but I generally do not enjoy driving cars with automatic transmissions very much. My S4 is DSG and while it's a good car and reasonably fun, every time I drive it I think about how much better it would be with a manual.

Like countless other manual, more visceral, connected ways we used to interact with our cars that have been made automatic or power assisted, it's being replaced in most vehicles with automatics or dual clutch sequentials. Manuals used to be better for performance and fuel economy, now there are other ways to deliver power that are better. As I mentioned above, I think big trucks are still maintaining a clutch pedal. I am not familiar with any tech there, so they may be moving to automatics, like buses, trash trucks, etc did many years ago? Are there automatic systems to switch between the gear ratios on the axles?

As far as the Corvette "no longer being a Corvette", if that's your opinion, I'm sure it's valid to you. You weren't in the market for one, it seems like yelling at clouds.

I think the C8 is a nice evolution of the brand and it should show it's taillights to much more expensive sports cars, which was always the point.

That VW transmission sounds like Porsche’s Sportomatic, which couldn’t shift on its own, but Porsche still described as an automatic. Motorcycle transmissions are completely irrelevant to the discussion.

Volkswagen and Audi describe their dual clutch transmissions as automatics.

The media describes DCTs as automatic.

Chevrolet does not call it a manual (though they do not call it an automatic explicitly).

It shifts automatically. It fits the definition of automatic. It is capable of shifting on its own without human intervention.

It is an automatic.


These are facts. Why you can’t get them through your skulls is a mystery to me. A DCT is functionally the same as a torque converter automatic. Everyone agrees. Everyone but you three, apparently. I don’t know what’s making you guys act so ****ing stubborn over this, but you are wrong, you were wrong yesterday, and you will always be wrong unless you accept fact.

I've heard single or dual clutch sequential transmissions referred to as automated manuals, since there was a clutch, the transmission guts resembled a traditional manual, and in many there was some level of interaction to make them operate properly (a la BMW's original SMG in my E60 M5). Most car people I know make a distinction between an automatic utilizing fluid/torque converter vs other automated shifting transmissions. Keep in mind that many automakers refer to their sequential or dual clutch transmissions as automatics to make them simpler for the car buying public to understand.

And to stop that buying public thinking they’re buying something avant garde (read: better ). repeat (especially older) customers don’t like change (pardon the pun)

I repeat: DCT FTW ( this is fact )
