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

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

I'd guess that if it's the DI V6, it will be setup the same way as the CTS. How is the CTS configured?

If the CTS has DBW, does it at least TRY to pretend it's a cable throttle, or does it try to guess what you really want rather than obey your foot?

ANY newly developed from the ground up car will have the latest tech, its just easier to do things, engineering is already done.

That said I believe the CTS is DBW and I EXPECT the camaro in all trims to be DBW.

DBW is a good thing it opens soooo much more tune-ability, just like EFI over CARBS.

DBW

when i drove the dodge srt cars at the srt track experience the dbw that they used sucked. it takes control away from the driver and if i can change that on my camaro i will.

I think we'll all be satisfied with the system in the Camaro. As time goes on, these advanced systems will be more sensitive to driver control, especially in performance-oriented cars. I'd expect GM to have developed a very sophisticated system to support the hype over the new Camaro.

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 hope there is a way to tune the throttle to exactly what my foot is doing if it isn't already like that. My experience with an auto cobalt and dbw was horrible, it took to my guesstimate almost 2 seconds to shift down a gear and rev when i step on it! With a shift kit it might be better though.

You can count on all DI motors being DBW. When cruising they go into an "ultra lean burn" mode where they open the throttle pretty wide and slightly reduce they amount of fuel injected (for the load compared to port injection) to reduce pumping losses.

I donít believe there will be much you can do to convert it to a mechanical throttle, but Iím sure the tuners will do their best to correct any short comings.

I believe we have been promised an ďaggressive throttle mapĒ.

I personally like having a throttle cable, BUT I'm not going to write the camaro off until I've driven it, and I'll probably buy it anyway.

NICE! That is something I was hoping for but it was sounding like that's not the case. I'm glad to hear it is. That's like hypermiling without the controversial behaviors!

I'll settle for consistent.

They might as well call German engineering impossible engineering. I know how to do basic maintenance on cars but I will not TOUCH any friends car that is from Germany, no no no. My old porsche 944 was a nightmare, and that was 1980's technology!

I know it WILL be DBW, all I want from the it is to move with my foot exactly as I move it like an "electric" cable throttle, while still maintaining its fuel saving abilities, traction control, and all that other stuff.

I've never encountered a problem in my Cobalt with Drive-by-wire...Whatever my foot says, the throttle does. No hesitation, no guessing. So I'm not worried in the least.


And for what it's worth, the base Corvette, Z06, AND ZR1 are all Drive-by-wire...............

I donít think youíll 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).

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. :(

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?

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...

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!
