I still think a continuously variable transmission (CVT) could be superior to everything if they could just make them reliable. I think everybody except Nissan has abandoned them.
they are much lighter and smaller and cheaper... and infinite gearing is better than having gears. now it does sound funny when you stomp on it and it just stays pegged at 3k rpm. |

Subaru makes a great CVT though I think it's only mated to their 2.5 liter H4.

As an engineer, you overstated the task. It is simply make the vehicle operate at it's most efficient level. Period. Why should I be restricted to as few gears as possible? 2 or 3 more gears provides much more latitude in balancing performance, economy and drivability. Don't fear the gears. Quote:

I like the idea of the 8speed...room for clutch material is in question though...as to that limiting torque holding. Dodge is doing it though.

Camaro will still remain a relatively inexpensive option compared to other sports cars that provide similar performance. Quote:
Now...I'm with you that on the point of not liking overly shifty and confused acting transmissions, but done right these can be a good thing. I think the 6 speed auto in my Camaro is freaking wonderful, and honestly I'd hate it if the next version had an 8 speed and it never knew which gear to use but I have faith it won't turn out that way. What I'd like to see, is another regular drive, sport drive, and manual, but maybe in the manual they only let you use 6 gears, instead of 8?? As far as straight line performance, well I don't know how many gears are too many, but Dodge/Chrysler has proven easily that 8 speeds can out run 5 (I think they had 5 before in their sedans....or was it 6?)

Yeah KMPrenger, they had 5 speed autos.
Personally I think the new 8 speed will be a phenomenal transmission, especially since the 7 speed Tremec has already been shown to be more than amazing. As someone mentioned a 7 speed infiniti already, and having driven a 7 speed Mercedes, they are not "overly shifty". Spot on every shift, very smooth when cruising but man, they shoot off when you want them to. And the addition gear in a 7 speed auto over a 6 speed auto lets you run either 2 overdrives or an additional acceleration gear... The 2015 Corvette with the 8 speed will be ridiculously fast with a high rpm cam.

Assuming the 6th-gen car gets the LT1 and eight speed auto, do you think that means the Camaro will also get the seven speed manual?

Everything that Chevy is going to do sounds expensive, but it's really not if you look at it. Chevy always gives you what you need in a vehicle, but usually, the overall tech behind American cars is a few years behind Germans and Japanese. Once American companies get there hands on certain types of tech. It's been done already for a while.
Ex: BMW and Nissan sports cars have been implementing carbon fiber since 2007. A costly venture for both companies. Chevy is using carbon fiber in standard vette components now. Though 7 years late to the game. Chevy doesn't outsource carbon fiber parts. The make their own CF parts. This brings the savings to the customer. This will push other companies to follow suit if they want to compete. Chevy thought out of the box to give you more for less. But to do that, they sacrifice being in the forefront of technology. Also... Nissan DCT is very expensive and cutting edge. Chevy's 8 speed auto will "hopefully"be revolutionary in performance but it is tactically evolutionary by design, thus saving DCT costs while still offering the performance. These are ways Chevy can give u more without you feeling it in your wallet. Lastly, by the time Chevy sees the alpha, Cadillac would have recooped it's R&D money +profit on the platform. When Chevy starts using it, the alpha will be at a lower cost of production. (Unless we enter another fiscal crisis) |

If you look at the max speeds in each gear for most the 6 speed and 8 speed automatics out there, there is very little difference in shift speeds/rpms in the lower gears.
You also hit your top speed in usually 5/6 gear and 7th and 8th are just overdrive gearing not even used in a top speed run. The biggest difference is you'll get lower rpms in the high gears and that will increase gas mileage (that's really what it's all about). All I know is I don't like the current tap shifts on the Camaro. That's something that needs major improvements. Guys that try to race (tap shifting) their L99 A6s know how hard that 1-2 shift is at WOT because it comes on so fast. 1st gear redlines at 40 mph in the L99s so you have to hit the tap shift around 35mph to prevent bouncing off the rev limiter. It would be counter productive if the Auto Camaro SS had to shift any earlier than the current setup on the 1-2 shift. In the LS3 manual, redline isn't until 53 mph on the 1-2 shift. |
