From R&T (and everywhere else):
But Corvette Engineering and the Lead Engineer said the 8 speed is "just as fast" and "in some cases faster than the PDK" ! ? !It Might Be Dual-Clutch Only
While GM has filed a patent for a clutch-by-wire system that replaces the traditional hydraulic master- and slave-cylinder mechanism with an electronic actuator, many signs point to the C8 being a dual-clutch only affair.
Back in 2016, our colleagues at Car and Driver reported that the C8 would use a seven-speed dual-clutch gearbox sourced from Tremec. Of its seven speeds, the top three are overdrives, and Tremec says it can handle 9000 rpm input speed and 664 lb-ft of torque.
Car and Driver argues that Chevy will only offer this Corvette with one gearbox to reduce cost and complexity, but a world without a manual-transmission 'Vette is hard to imagine. Still, a dual-clutch would be a big improvement over the current Corvette's eight-speed auto.
Latest word is that they may use the exact same ZF transmission that is in the 2020 992 Porsche 911.
I would hope sometime after the launch they have a manual option available to order.

There are two feral cats that hang around the area, and I always see them running out from underneath my truck when I come outside. I have always wondered if one is going to inadvertently hitch a ride one of these days.

Ah, okay. I haven't watched it since the first season after the punch heard 'round the world. They had brought on enough hosts to start a sports team.wap wrote: ↑Tue Jul 16, 2019 10:39 amJust 3 plus The Stig, and occasionally Sabine.Huckleberry wrote: ↑Tue Jul 16, 2019 6:43 am

I haven't watched Top Gear since The Grand Tour guys left.

It had gotten pretty with Chris, Matt, and Rory, but these 2 new guys with Chris aren't doing it for me yet. You just can't plug 3 guys in there and expect the type of rapport that the Clarkson, May, and Hammond have. It feels forced and fake.
