No sports car should have chrome wheels. The 2015 Chevrolet Corvette Stingray convertible you see here does. It also has an automatic transmission, GM’s new in-house made and -built eight-speed product, that swithces past year’s six-cog part taken more than from the C6 Corvette. The modern transmission has two things going for it: Very first, it's got more speeds in the era where more is more, and second, purchasing this doesn’t require all those shiny wheels.
Our team already driven a gaggle of Corvettes built with the latest eight-speed, dubbed 8L90, plus came away amazed. Well, we're mainly amazed; the cheap - feeling plastic steering-wheel shift paddles threaten to drag in the knowledge. A shift handle doesn’t give a manual-shift entrance, thus choosing your purchase gears needs use of such flimsy actuators. Chevrolet ought to upgrade the pieces recently, lest consumers neglect the new eight-speed outright in its regrettable visible and also tactile deficiencies.
Luckily, everything else about the $1725 transmission is better performed. Our team noted the same 3.7-second 0-to-60-mph period in this convertible as we do in a 2014 version with the six-speed automatic; through 80 miles per hour, the latest Vette starts to pull away, and by 150 mph, this edges out a 0.7-second lead appreciation at least partly to faster shift moments. A transmission’s logic along with broad rate spread elevate a self-shifting Corvette experience toward Porsche PDK dual-clutch-automatic levels of satisfaction. Climate, Eco, Tour (normal), Sport, and Track types provide drivers the spectrum of behaviors. In Road, the 460-hp V-8’s lightning-quick accelerator response and the electrically boosted steering’s increased performance combine incredibly along with the transmission’s rev-matched downshifts plus redline upshifts. Clear the red vapor by converting to Tour and also Eco, and the 8L90 blends with a preponderance of calmness.
The EPA states that while the 2015 Vette with the eight-speed material the same 16-mpg standing at the city period as the 2014 type, the freeway quantity increases from 1 miles per gallon to twenty nine. This test car’s participation with our challenging 10Best testing stifled gas mileage with a depressing 12 miles per gallon, yet we’re convinced which together with normal choose, it may greater the 18 mpg we noted with the previous transmission.
