The electronics actually provide what Customers in general want and in a lot of cases are lower cost ways of doing things than having mechanical parts. I am pretty sure the power window electronics no more to produce than the mechanical window regulators and weigh less as well. People complained about the doors not closing easily on C5s due to the pressure build up inside the car. So they fixed that in the C6s and C7s by indexing the windows. Since a fair number of Customer's want power windows and want the doors to close why would they even think of installing a mechanical window regulator? Just having an unpopular part in inventory requires money to manage the inventory and money to manage the engineering records related to the design along with different procedures for cars coming down the line. They give the Customers what they want, reduce costs and improve quality by doing that. A triple play. There are other features in the car that provide the same type of benefit. Hell it is even better to have the power seat track when on track because you can use the seat belt cinch mode and the power seat track to get the stock 3 point belt tight as hell. A mechanical seat track like they offered on the C4, C5 and C6 passenger side just didn't cut it from helping to get the belts tight as required.
Maybe the C8 will also introduce a 48 Volt electrical system which is one thing manufacturers are studying since it can cut down on wire size thus reducing weight even more.

Seems the big sore spots of these cars are electronics being too complicated/integrated, paint has been addressed of course trans
why cant these systems be simpler? Do power windows really need to communicate with everything else, HVAC, etc
Id think the consumer knowing these were simpler to figure out would increase the audience thats all (not to mention cost of maintenance & repair)
Does anyone really need more than 6 or 7 gears? (dont phase out the manual!)
Most new cars are throwaway items due to these issues may less is more.
Flame away guys

The "big boys" of your car; the engine & transmission controllers(PCM/TCM/ECM), brakes (ABS/EBCM), airbags (RCM), and body controller (BCM) control most of its critical functionality, and nearly every module talks to those modules.
Things you might not know:
Your vehicle speed comes from the ABS module derived from wheel speed sensors.
Inertial sensors that determine Lateral, Longitudinal, and Vertical acceleration as well as Pitch, Yaw, and Roll moments are done by the airbag module.
You BCM actually controls all the interior stuff like memory seats, windows, keys etc. sometimes thru "daughter modules."
This leaves the engine controller to worry mostly about its self, but lets not forget the engine and transmission are complicated enough already BEFORE you put them in a car.

Unlike your PC a car is what we call a distributed system, meaning each computer only controls the bare functions it needs to, getting information when it can from other modules.

started when everyone started complaining that the seats stunk cheap interior, blah blah
yup and then all those tank like electronic enclosures and cables and do wizzies and stuff crept onto the car and surprise, it's a heavy pig again.
so riddle me this. why with all our advances can we not look at ways to trim a bit of the lard. come on guys, we need 500 hp, 3000k lbs, and world class looks and handling
those are my requirements and chevy was close way back in 2003
fast forward we've added super high tech materials and still gained weight
indulge me here 03 z06 steel frame, ok dash, stiff car, cheap 3150 or so
c6 z06 alum frame, nicer interior, 427 with lots of torq car nuges under 3100 for the first time in a long time
so back to the window crank thing. you sure can make it lighter, phone glass window is lighter, so motor can be smaller, or look at the old race cars that used a strap for the "window lift", there are lots of ways to innovate like vette did on the vent openers, you get the point. Car needs to be on a diet and be much more lithe and tossable and as far as stocking parts. Parts left out don't weigh much or cause inventory hassles. every part that corvette has unique to the car comes off the bottom line and get rid of the vette tax which is never good.
vette has had a "truck engine" in it for a while now, how about a proper dohc v8 for a change. ok, now slap a pair of hair dryers on it, call it a c8 and make a McLaren killer for half the cost and oh by the way sign me up!
Vette needs to consolidate thinking a bit here and stop trying to be such a luxo barge. tight like a tiger and agile like a mountain goat.
take the styling from the old c3, and make it look like the pure sex race car without the tacky plastic wings on the back (come on chevy, looks like a transformer matel toy, not a race car)
make sure the lines flow and the curves are sexy like the old days, with the aero that is needed for top end. seen many styling examples that sure look better than the c7 which is a functional car, but not as pretty as it could be
corvette is a pure emotion and automotive art. look at the brits db designs and you see clean yet aggressive styling
the c8 needs to be all these things and more, and keep it under 100k with the normally aspirated "z06" variant for the track guys and the twin turbo version as the halo car
make it rev to 8500, have a power band as wide as the hoover dam, and knock out sexy. sold.

You will never get a striped car for 3 reasons.
1. Regulations drive much of the existing stuff (you need ABS, Stability Control, Airbags, specific types of glass)
2. Going faster drives even more tech (you want MSRC, and advanced Stability features)
3. Customers will not buy a car that doesn't have basic amenities (even a Sonic/Fiesta/Yaris/Fit/Versa has power windows and door locks)
FYI DOHC weighs more displacement for displacement than an OHV engine, granted it also makes more power, but you're way off base with reality in your requests.

Ok say Mercury Marine takes on the DOHC...that will be a winner history repeating itslef all over. that will sell the new vette like no tomorrow
Few of us know how durable those are. now that would get my attention a literally fool proof motor. Do it Chevy
Add a quality ZF built transaxle you got a winning combo. Modern day Pantera..thats reliable.
close ratio trans stiff rear gear base trim. Id find a way to live in it haha
