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.

Cool story bro!

WAIT, Wait...wait...

An automatic performs better than a manual?

NO way. Not possible. Automatics are for sissies. Only REAL men drive manual transmission cars. Right?

Well, if the L99 SS wasn't short 26 HP, I'd probably be driving the A6.

So damn easy to make up for that with a few mods!

I think it is going to take a little time to see the good track times come out for these. There are so many variables - traction control, launch control, now the new tap shift - that I think it is going to take a while for the general enthusiast to get the really good times.

Still, the moment everyone waits for, is when Evan Smith gets to take it to the track. I hope they give him both auto and manual this time, though...

Very impressive indeed, but I would still prefer a manual in a car like that. I would be driving on the street much more than on the strip .

The times are a changing... Back 10 years ago, I would of never considered an auto for a true sports car. But with the technology coming around auto's just make plain sense to have.

I'm with slappy though, a manual is still more fun to own.

When I purchased my Z/28 back in 1995 I test drove both the M6 and A4 versions back-to-back. I purchased the A4 because it shifted faster than the M6.
