Chevy Camaro ZL1 10-speed auto shifts faster than Porsche PDK
Company claims first to second, second to third, and third to fourth are all faster than the German dual-clutch.
According to Chevrolet, the new ten-speed automatic excelled in testing. The company claims upshift speeds from first to second, second to third, and third to fourth are 36-percent, 27-percent, and 26-percent quicker than Porsche's PDK, respectively. Now, the PDK is already among the fastest shifting gearboxes money can buy, so picking out the performance difference between the two will probably be impossible outside of a closed testing environment. But that doesn't make this claim any less impressive. How is Chevy pulling it off? Clutches. Lots of clutches.
The new ten-speed has six clutches and they allow this automatic to behave a lot like a DCT. For example, when the driver calls for an upshift, the transmission already has the next gear primed and ready to go, just like the PDK. At the same time, there's a torque converter, like a normal automatic. According to GM Global Propulsion Systems Vice-President Dan Nicholson, the combination gives drivers "world-class shift times on par with the world's best dual-clutch transmissions and the refinement that comes only from a true automatic."
We can't wait to put that claim to the test.
