New gearbox sheds 8 pounds will also seem in the new Z06
2015 Corvette Stingray consumers will have a new transmission option when they head to dealer lots next yr: An 8-speed automatic that will supposedly excess weight significantly less than the 6-pace it replaces and boasting quicker shift occasions than the dual-clutch in the Porsche 911.
Named the 8L90, this 8-speed will be constructed in Ohio and will also be located on the upcoming Corvette Z06. If the gearbox is capable of dealing with the 625 hp place down by that supercharged beast, we’;re certain it’;ll consider on the normal Stingray’;s 455 hp with out breaking a sweat. In fact, GM says the 8L90 bound for the non-Z06 Vette has “unique clutch and torque converter specifications matched to the torque capacity of the Stingray’;s LT1 6.2L naturally aspirated engine.”
The 8L90 is not, nevertheless, the 8-velocity identified in the 2014 Cadillac CTS. That car’;s automated transmission is created by supplier Aisin, at least for now.
Of program, improved fuel economic climate is the primary driver behind the 8-speed’;s impending adoption. Aluminum and magnesium elements mean the 8-velocity is lighter than the soon-to-be archaic 6-velocity as effectively — in a day the place every ounce would seem to count, that is not too shabby. No word nevertheless on how it improves on the 17 city/29 highway fuel economic climate ratings won by the 6-pace manual-equipped 2014 Stingrays.
In accordance to GM, the added gears won’;t harm functionality: “wide-open throttle upshifts are executed up to 8-hundredths of a second quicker than those of the dual-clutch transmission offered in the Porsche 911,” an official release guarantees. Steering wheel-mounted shifter paddles need to give drivers at least some handle over what the gearbox is performing.
We definitely value the manual-outfitted Stingrays we’;ve driven so far — that 6-velocity guide supplies one a lot more way to interact with what is one of the most rewarding driver’;s cars to come out of an American automaker in recent memory. But not every person likes to row their way around town, and we’;re keen to see if the new not-so-slushy slushbox can hold its very own towards the greatest the Germans have to supply.
It undoubtedly wouldn’;t be the very first time we have put a Bowtie-wearing efficiency vehicle up towards a Porsche.
