Along those lines, you'd think that people with PDKs would just put them in automatic mode when driving on the track right? I've driven Porsches before, if you're mashing the pedal to the floor in "Sport", it'll go to the lowest possible gear, and it'll downshift for you when you brake. The shifts are so fast it might as well be a CVT. Why do these people even bother with the paddles?

It's about control over the elements in the car

Not a Cayman, but someone does.

I don't have an "ideal" really, it would be great to have some variety IMO... I think a small electric sports car would (could, anyway) be brilliant. But I also love the sound/feel of some ICEs.

disclosure: I was the structural engineer at an electric vehicle company for a number of years. We built a large electric scooter/motorcycle similar to a Suzuki Bergman 400. Our electric drive system felt better than the "being pulled by a stretchy rubber-band" feel of CVT gasoline scooters. Cars with discrete-ratio gearboxes (manual or dual-clutch) don't suffer from that rubber-band feel, though, so not really much improvement to be had there.

I think the biggest improvement is simply not having to operate a clunky and mechanism to change gears. Upshifts in my base/manual Cayman just felt so *painfully* SLOW after driving the PDK... Lost time!

But for sure we are transitioning to more electric cars. And there by God *should* be some great electric sports cars in our future. I'm looking forward to it. Kinda...

Not a Cayman either, or a Ferrari—just a Chinese knockoff—but it’s electric.

Wait, MORE commonly? I would venture to guess that there are VASTLY more drivers of Corvettes, FT86s, Porsches, Ferraris, etc. who do NOT race and for whom lap times don't matter (beyond those produced by others for bragging rights for "their" car).

—Less commonly, there is the driver who is racing themselves, who is just trying to best their old times. A manual is another obstacle that challenges their skills and offers reward when executed properly. These people find most reward in driver engagement and in having feedback from their car and when they’re able to use that information successfully. How they win is more important than winning. Having fun and winning is not synonymous.
Well, I am definitely in it to improve my lap times. And I'm all about feedback from the car. At best a manual transmission is direct and has short throws and quick engagement times. But short of a sequential box they are all very slow. And a sequential dog-box is not really an option for most of us for most of our cars...
A "normal" manual is just slow. Painfully slow. And operating an awkward-at-best mechanism is not "driving". Braking at the limit, trail-braking at entry, squeezing on and modulating the throttle, and of course steering are driving. Shifting and clutching a manual box are a means to the end of performance driving. With an ICE engine I do like to be in charge of when upshifts and downshifts happen. But I don't need to operate the actual mechanical linkages myself, any more than I feel the need to manually change ignition advance or valve timing myself.


Quote:
An excerpt to explain my point, which can apply to the nannies like it applies to a manual:
Nannies are a totally different thing. Personally I like to be in complete charge of the throttle and not to have stability controls intrude (even when the systems are very good as with Porsche). Hell, I'm not even a fan of anti-lock brakes at the track. When a sensor went bad on the S2000 years ago, I dailied and tracked it for 5+ years without ABS...

CHEVROLET INTRODUCES FIRST HARDTOP CORVETTE CONVERTIBLE

https://media.chevrolet.com/media/us...-corvette.html

Quote:
2020 Stingray convertible offers the same storage as coupe, even with the top down
2019-10-02

CAPE CANAVERAL, Fla. — Open-air driving has always been a part of the Chevrolet Corvette’s heritage. In fact, when the Corvette debuted in 1953, it was available only as a convertible. The 2020 Chevrolet Corvette Stingray convertible builds off that heritage as the first hardtop and mid-engine convertible in Corvette history.

“We put the world on notice when we introduced the first mid-engine Chevrolet Corvette a few months ago, and now we’re raising the bar with the first-ever hardtop Corvette convertible,” said Brian Sweeney, Chevrolet U.S. vice president. “And the convertible will be priced only $7,500 more than entry 1LT Stingray coupe.”

First and foremost, a convertible

The mid-engine 2020 Corvette Stingray was engineered first and foremost as a convertible. The convertible maintains the tunnel-dominant structure and use of high-integrity die-cast parts found in the Stingray coupe.

The team engineered the hardtop to stow seamlessly into the body, maintaining the Stingray’s impressive ability to store two sets of golf clubs in the trunk even with the top down. The convertible also keeps the coupe’s front storage compartment, which can fit an airline-spec carry-on and a laptop bag.

The hardtop provides a quieter cabin, increased security and a cleaner look compared to the previous softtop designs.

“Our goal from the beginning was to make sure customers didn’t have to sacrifice any functionality, performance or comfort when choosing the hardtop convertible,” said Josh Holder, Corvette program engineering manager. “We managed to keep the same design theme as the coupe, as well as the exceptional storage capacity and track capability.”

Inspired by jets

Like the coupe, the Stingray convertible’s design was inspired by fighter jets. The tonneau cover features aerodynamically shaped nacelles influenced by the housing used for jet engines. The nacelles, which were also used as inspiration on the Chevrolet Engineering Research Vehicle (CERV) I and II, as well as the Corvette SS and SR2 concepts, help reduce air recirculation into the cabin and provide a remarkably exotic profile with the top up or down. The tonneau also provides a rear power-adjustable window and a vent for mid-engine cooling.

The two-piece top can be activated at speeds up to 30 mph and retract in as few as 16 seconds. It is powered by six electric motors — a Corvette first — and uses encoders for precise control. Switching to electric motors from hydraulic systems helps increase reliability. A body-colored roof is standard, while Carbon Flash metallic-painted nacelles and roof are optional.

Careful attention was paid to make sure the engine could breathe when stored underneath the tonneau cover. The sheet-molded composite top stows in a compartment made from lightweight composite panels and heat shields to manage heat from the engine.

A divider glass window in the middle of the vehicle can be power adjusted with the top up or down. The glass has been optimized to reduce air recirculation and wind noise in the cabin for improved quietness. The roof system design, combined with the same rear spoiler used on the Stingray coupe’s Z51 Performance Package, results in identical drag between the coupe and convertible with the top up.

Engineers tweaked the chassis for the convertible, with springs and dampers tuned specifically to provide nearly the same performance as the coupe.

No compromise performance

Like the Stingray coupe, the convertible is powered by the next-generation 6.2L Small Block V-8 LT2 engine, the only naturally aspirated V-8 in the segment. It will produce 495 horsepower (369 kW) and 470 lb-ft (637 Nm) of torque when equipped with performance exhaust — the most horsepower and torque for any entry Corvette.

The LT2 is paired with Chevrolet’s first eight-speed dual-clutch transmission, which provides lightning-fast shifts and excellent power transfer. This transmission is uniquely designed to provide the best of both worlds: the spirited, directly connected feeling of a manual and the premium driving comfort of an automatic. The double-paddle de-clutch feature even allows the driver to disconnect the clutch by holding both paddles for more manual control.

When combined, the advanced propulsion system, revised chassis tuning and retractable hardtop make the 2020 Stingray the most no-compromise Corvette convertible in history.

Build and price tool now available

Interested Stingray shoppers can now build and price their own Corvette coupe or convertible on the 2020 Corvette visualizer at Chevrolet.com.

A dedicated Chevrolet Corvette Concierge team will provide 2020 Corvette customers with answers about the vehicle discovery, buying and ownership process. The team can be reached by calling 866-424-3892. Customers can also live chat with a Corvette Concierge by visiting Chevrolet.com. The team is available from 9 a.m. to 9 p.m. EDT Mondays through Fridays.

The 2020 Chevrolet Corvette Stingray coupe goes into production at GM’s Bowling Green Assembly in late 2019, with the convertible following in late first-quarter 2020. A right-hand drive version of the convertible will be available in select international markets at a later date.

Corvette is wasting no time getting the C8 into racing. The 2020 Daytona 24 Hours will be its debut.

it would be foolish if they did, I'm sure racing was a big part of why they went mid engine.

With the retractable hard roof I'm thinking I might like the "convertible" better than than the standard model.....

Also, they have the configurator hidden pretty well. You have to go to https://www.corvette.com then select models/Upcoming and pick the 2020 Corvette.

Then you have to scroll down about 3/4 way down the page and pick "Build YOurs' or something like that on the convertible model.

Here's a link to the configurator.

I'm pretty sure this is the king of "bang for your buck".

Sadly I cannot see them getting released here.
