slushbox supercar?
Why wouldn't GM just put a DCT in the Z06 instead of trying to make it look like one? They are obviously embarrassed about this or they wouldn't try to make it look like a DCT. I don't get it...DCTs have all the benefits of a manual and automatic at the same time. Slushboxes don't belong in supercars, period.

Someone get this man a tissue. Maybe a box of tissues.

Won't it be embarrassing when this slushbox car, leads all cars at the drag strip, road courses and track.

The new Jaguar F-type 8 speed auto slush box seems to be rather impressive judging by what I've seen and heard.
Watch this video and tell me it doesn't display many of the positive characteristics of a DCT

if it shifts as fast as the Aisian 8 spd used in many Japanese high performance cars, it will shift faster than many DCT transmissions. also, if it is supercharged as it must be with the 650 lb/ft torque leaked by GM, a torque converter automatic will have less boost loss when changing gears.
if you have driven some turbocharged cars, you may have noticed that the boost gauge drops off less while shifting on the torque converter based automatics than the manuals.
there is also less shock to the tires when accelerating from a dead stop. Porsche 991 carrera s can get away with this, even with launching @ 5000 rpm, with only 2wd since it has only 325 lb torque and 62% rear bias. Imagine what would happen launching a 650 torque z06 with a manual or dual clutch auto.

The Aventador does not use an auto. The gearbox it has is known as an ISR and is an advanced, but harsh, single clutch automated manual. It's closer to a manual than a DCT is.

Scraping the splitter.
Dig in, because there is going to be a long year if they start building later in 2014.
We're going to be hearing how GM cheaped out and should have offered a DCT.
We're going to be told that they should have revised the rear fascia to appease the "majority" of people who don't like the rear of the C7 (this includes that it should have had round taillights).
We're going to hear that they screwed up by not offering a bigger cube NA engine.
It's going to be bench raced to death against the C6 Z06 and ZR1, very likely with many owners of the latter telling us that it's not going to be as fast and GM is lying about its performance numbers.
Basically, the entire C7-Detractors Playbook will be brought out in full force.

Please do some research so you can atleast sound intelligent. If anything, a stick is the slushbox because it's far slower. 150 millisecond shifts are as fast as the eye can blink. That's what current 8 speeds are capable of with locking torque converters too. The Z's 8 speed may be even better.
It's still an automated paddle shift transmission just like a DCT with notable NVH characteristics too. If you prefer a manual that's fine but there is no debate about which one offers better performance.
