So whats the Deal with the L99?

Was it done for CAFE? I know the 6 speed auto can handle the LS3 since the Vette has one and STS-V does too. It just doesn't make much sense to design and certify another V8 for the SS that is so close to the LS3. L99 has AFM and LS3 doesn't right?

Yeah, according to the site. As well as 22 less horsepower.

I guess guys who wanted an automatic trans got the shaft.. I'm just thankful the CAFE isn't quite bitchy enough yet to not allow me to get a Camaro.

The L99 is hiding horsepower or a sweet torque converter. Its quicker than the LS3 6sp through the quarter and 0-60 times GM released.

It's only two tenths quicker, and we don't know anything about how they launched the cars. We should wait until we get actual test results from tons of actual Camaro owners driving actual production cars.

If there really is an advantage with the automatic, though, I credit the gear ratios in the 6L80.

Not a chance. From what I've read the auto with the L99 is a nice setup not
to mention tapshift as well.

Quicker than the m6? I wonder what the mph diff is? Well gotta wait till actual test numbers 'cause low 13s for a six speed is not impressive

The difference is likely in the fact that other AFM cars have had a very loose and higher stall torque converter. Which covers up some the jerks of AFM mode changes. This is likely a good thing for the Camaro... it just makes city gas mileage worse.

Anyone know the shift times on the tap shift?

At least partly for CAFE, partly to avoid gas guzzler charges (remember that penalty on the A4 GTO?), and partly to advertise a higher MPG. The A6 G8 GXP is projected to be a guzzler. I wonder if it's too late to put an L99 into it.

the GXP is a manual.

On a manual transmission, shift times are usually based on the amount of time that elapses in which the clutch (or clutches, in the case of a DCT) is disengaged.

It's an automatic. No clutch, and it's never disengaged for any amount of time. What events would you like to use to time the shift?

Or, did you mean shift delay (i.e., the amount of time that passes between when you hit the lever and when the transmission actually starts to shift)?

Both will be available. The A6 version will probably guzzle. The M6 with skip shift probably won't -- just like with the GTO.

The A6 has AFM so I think it will bypass the guzzler tax.
