Will the V6 have DBW or a good old fashioned cable throttle?

I don’t think you’ll get that either.

I believe that the new torque based DBW systems look at throttle position and a few other things (gear, load, shifter position) to figure out how much torque you want and adjust the throttle, A/F ratio, valve timing, AFM mode, hybrid mode and shift the transmission (as applicable) based on that.

On the bright side I think that this:

Ends up being a little quicker than a cable
Probably saves a little fuel
Should be transparent (or better than a cable) if done well

Hopefully it will even come with a sport mode like the MINI S has where the throttle is more responsive, the auto shifts more aggressively and the (electric) power steering is less boosted (for road feel).

Not sure what my 2006 Monte Carlo w/3900 has but it works great. Never any hesitation.

DBW in the manual transmission shouldn't have any delay, right?

Personally, though, I like having a cable, so you can feel the engine and road through your foot.

It has random, inconsistent rev-hang in my overengineered VW with a manual transmission. :(

We'll just have to see how things work when the car comes out. The magic eight ball says "Cannot predict now."

So, while discussing the VW's rev hang elsewhere, I began to notice just how many e-nannies it has. About the only thing it doesn't do is read speed limit signs and cut fuel when exceeding the limit.

Does modern G8 or Corvette have e-nannies like Engine Brake Assist, which delays RPM drop if you let off the gas while in gear to prevent skids caused by compression braking?

Not sure, though it sounds like a neat little system.

It's dreadful.

They have rev-matching with the auto trannys. Which blips the throttle or cuts it a little to properly match the next gear. I'm not aware of any engine brake assist on the new V8s...is sounds like the 4th gens attempt at stability control...They've all got Stabilitrack to prevent skidding...

My 2008 VW has DBW throttle, and it's rather inconsistent, apparently trying (and failing!) to guess what I really want rather than what my foot did. It's kinda tough to rev-match...sometimes I hit the pedal and it doesn't respond at all, other times with the same pressure on the pedal it jumps up to 6000rpm. Then there's rev hang, which is stuck throttle's bastard brother...

I have a 2006 2.0T FSI 6MT in my Passat. The DBW is exactly as mentioned above. It causes me a lot of headaches, and when I get into my Supra with its 90MM throttle body, its like trying to paint the whites of the little eyes on tiny figurines with a Wagner power sprayer.

Actually, I was thinking about this the other day...around the same time I posted this thread, I also posted elsewhere about how the DI engine can run very lean and may not even need a throttle at all (like a diesel engine), and it was kinda dumb for me to then wonder if the throttle would be DBW or cable. D'oh!

[Beau]

Well to put this to rest. The CTS = DBW, the Bosh Motronic ECU is also the same.

Which means the CTS = V6 Camaro.

The car is like a tank, but weird little programing bugs like if I had the doors locked before I closed the hatch, the alarm would activate even if I unlocked the doors while it was locking the hatch. It lead to sitting in the car, unlocked by the keyfob and the alarm triggering.

The problems with DBW are with the programing, not the engineering, and we have amazing programmers in North America.

Yup, that seems to be what I'm learning about it. They did a really unexpectedly great job with comfort, ride, and handling; the engine feels American, which is perfect for me; the transmission shifts really nicely; but they failed in so many other ways. DBW, electronic automation (such as the programming bugs you describe), gearing, and this morning I found out that the heat doesn't work well (can't heat fresh air from 7 degrees F, all my American cars could; have to use recirc to get warm air) and trying to defog the windows is futile (even using A/C to dry the air).

Oh well. That's part of the reason I chose to lease this car. When I return it maybe I'll get to buy my Camaro (or try out some Korean engineering with the Genesis coupe). Overall I am happy with it, the good still outweighs the bad.
