Our team already driven a bunch of Corvettes equipped with the latest eight-speed, known as 8L90, plus came away impressed. Well, we're mainly impressed; a cheap - experience plastic steering-wheel shift paddles threaten to drag down the knowledge. The shift handle does not give a manual-shift gate, thus picking your purchase equipment requires usage of those flimsy actuators. Chevy must improve a parts recently, lest people disregard the new eight-speed outright on its disappointing visual and also responsive deficiencies.
Luckily, everything else regarding the $1725 transmission is better implemented. We noted the same 3.7-second 0-to-60-mph time in this model of convertible as we did in a 2014 type together with the six-speed automatic; by 80 miles per hour, the latest Vette begins to pull away, through 150 mph, this sides over a 0.7-second head thanks at the least partly to quicker shift times. The transmission’s logic and broad rate spread raise the self-shifting Corvette feel toward Porsche PDK dual-clutch-automatic levels of amusement. Temperature, Eco, Tour (default), Sport, and Track modes give drivers the range for behaviors. In Track, the 460-hp V-8’s lightning-quick accelerator reaction as well as the electronically raised steering’s higher alertness combine incredibly along with the transmission’s rev-matched downshifts plus redline upshifts. Clear the red mist by switching into Tour or Eco, and the 8L90 harmonizes with the variety of civility.
The EPA says that as the 2015 Vette with the eight-speed nets the same 16-mpg score on the city period since the 2014 type, the freeway quantity rises from 1 mpg into 29. This test car’s contribution with our brutal 10Best testing stifled fuel economy with a depressing twelve miles per gallon, but we’re convinced which with ordinary choose, it could better the eighteen miles per gallon we noted with the old transmission.
