GM: Faster TapShift Response gives ZL1 Auto an Edge

Staged up-shifts improve Camaro’s manual-mode performance by up to 60 percent
http://media.gm.com/media/us/en/gm/n.../0222_tapshift

DETROIT – When the new 2012 Chevrolet Camaro ZL1 arrives this spring, performance car enthusiasts will experience the hands-on driving satisfaction of a “stick” with the ease of an automatic transmission due to General Motors’ newly improved TapShift technology.

Since its introduction several years ago, TapShift has allowed drivers to control up- and down-shifts with paddle shifters. For 2012, GM powertrain engineers implemented a patent-pending software algorithm that improves tap response time by up to 60 percent compared to the previous system. No hardware changes were required for the upgrade.

“The faster you can get to the next gear, the better, and from the sound of it, the ZL1 automatic’s performance is going to make paddle shifting more exhilarating and satisfying for drivers of all skill sets,” said Eric Fedewa , director of Global Powertrain Forecasting at IHS Automotive. “We’re seeing a trend toward more manual-mode-capable, fun-to-drive automatic transmissions across all vehicle segments, and GM’s technology is leading the pack.”

The 2012 ZL1’s six-speed automatic transmission delivers a 0-60 time of 3.9 seconds – a tenth of a second faster than the manual transmission time.

By staging hydraulic pressure in the clutch for the next gear, the new control module algorithm reduces tap delay for the 1-2, 2-3, 3-4, and 4-5 up-shifts by 200-300 milliseconds. The system anticipates shift requests based on current gear, throttle, torque and speed. By pre-filling the clutch for the next gear, the tap up-shift response is near instantaneous.

“As great as the previous system’s performance was, we were driven to achieve even better results,” said Gabe Gibson, GM performance car calibration engineer. “Not only did we make the upgrade to Camaro, we implemented it on the 2012 Corvette as well, and will use it on all vehicles with TapShift control going forward.”

Staged up-shifts will help drivers of the 2012 ZL1 – the most powerful production Camaro ever – get the most out of its supercharged 6.2L engine that is SAE-rated at 580 horsepower (432 kW) and 556 lb.-ft. of torque (754 Nm).

ZL1 customers’ choice of an automatic 6L90 transmission with TapShift manual mode or a six-speed manual transmission is unmatched in its class. With 0 to 60 taking 3.9 seconds, and a top speed of 184 mph, the power and acceleration of the ZL1 automatic rivals many supercars.

“We think Camaro drivers will really appreciate the performance improvement offered by staged up-shifts, whether they’re merging onto the freeway or putting their ZL1 through its paces at the track,” Gibson said.

The Camaro ZL1 Coupe will go on sale this spring as a 2012 model. The Camaro ZL1 Convertible will go on sale this summer as a 2013 model. Chevrolet expects the automatic transmission to command up to 50 percent of ZL1 sales.
Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, and high quality.

Pretty cool!!

Here's a VIDEO of the shift response. Damn quick, if you ask me!! :thumbsup:

Thanks, Joe...

I don't think this makes someone like me make any clearer a decision after seeing and listening that video...

:D Great find! Now - let's see some owners with some +3XXX-stall converters!!! Low-11s (on DRs) anyone? :D

Sweeeeeeeeeeet, my only question is why did the magazines not test a auto ZL1:mad0260: Road & Track as well as Automobile Magazine were quoted as saying there was one there during testing:iono: Posting the auto ZL1 times could have avoided the times for the ZL1 being all over the place.

radz28 02-22-2012 12:14 PM

There was a review in maybe Car & Driver where it was their opinion the shifting was abrupt during some driving situations. They were not displeased, as I guess they left it in "Auto" mode, but they didn't like the timing or something...

motorhead 02-22-2012 12:23 PM

Glad I changed to the auto. Now if it were only here. Great read! Thanks!

Does this mean the SS and V-6 autos will have improved tapshifts?

Also curious about this for future models and if it is simply a "software change" shouldn't it be available as a firmware update to existing owners?

ZL1 stuff makes everything better. :chevy:

CFD 02-22-2012 12:29 PM

It also claims no hardware changes and the improvement is in the software, I wonder if our cars can be upgraded?

Joebot8484 02-22-2012 12:47 PM

That awesome, although I ordered a stick, I would still like to try out paddle shifting:drool:

G8GT4now 02-22-2012 01:20 PM

It sounded like all those shifts in the video were WOT upshifts. I'd be curious to see how part throttle upshifts as well as downshifts are improved over previous software algorithms.

I'd like to know if this software would be available to '10s and '11s as well.

GM please read this
 
gm would make a million dollars a day on this alone! I see no reason any l99 owner wouldnt buy a gm approved tune to increase tap shift response. The only barrier right now to any tune is loss of warranty. That Gabe Gibson engineer should get a nice bonus too.
Lets push for GM to make this new algorithim available to current L99 owners as well.:headbang:

Team L99

Sticking with the M6, but it sounds like a win-win for GM

duffmobile 02-22-2012 02:08 PM

another vote for this on my 10'! Let's make it happen GM.

Agreed!!

rickadu 02-22-2012 02:16 PM

Stick used at the Ring .............. no auto for me. I use auto in my wife's SS.

mlee 02-22-2012 02:22 PM

LOL.. just saw this one earlier... Tapshift on the back of the steering wheel will always be worthless especially on a road track.

What I did like to see was the firmer shifting and what is sure to be a much tighter tuned transmission than the SS. Makes me go hummmm

I agree, that's why I developed the tapshifter.

K32 Camaro 02-22-2012 02:32 PM

That's cool but.. that top speed can't be right.. can it? Only 184? Isn't the ss about 175?

Kyle2k 02-22-2012 02:36 PM

Gah, how jealous is GM trying to make me!

I believe Ferrari placed their paddles on the new 458 Italia in a similar position and received some ridicule but their reasoning was that a driver SHOULD NOT be changing gears during a turn...:rolleyes:

I know on roadbikes at the track guys shift in a turn all the time and it makes for quicker lap times so I don't see how that concept wouldn't transfer over to 4 wheels. But who am I to judge, Ferrari has one numerous F1 championships so I'm sure they know more than me about racing cars.

I think this is great news for auto owners. I just couldn't justify the extra $1300 Gas Guzzler tax and the $1200 for the auto...But I would definitely be a happy camper if I ordered one this way!

alcal1084 02-22-2012 02:42 PM

I had a 2010 camaro and now have a 2012 both autos and the tap shift is faster on the 2012!!!

HAHA!! The "AUTO" is the answer to 650 HP my friends! :D :thumbsup:

Thanks for the post Dragoneye! Good to see some more GM input on this auto. Would like a bit more!

Not to turn this into another one of those threads but this is exactly why I said in another thread that the ZL1 auto will hang with the "other" new car in a 1/4 mile.
