No expensive car need to have chrome wheels. A new 2015 Chevrolet Corvette Stingray convertible you see here does. It also comes with an automatic transmission, GM’s new in-house developed plus -built eight-speed unit, which replaces last year’s six-cog part carried more than on the C6 Corvette. The new transmission includes two things going for it: First, it's got more speeds in an era that more is more, and 2nd, ordering it doesn’t require those shiny rollers.
Our team already driven a gaggle of Corvettes built with the new eight-speed, named 8L90, and came away impressed. Properly, we were mainly impressed; a cheap - experience plastic steering-wheel shift paddles threaten to pull down the knowledge. A shift handle doesn’t offer a manual-shift gate, thus choosing your own gears requires usage of these slight actuators. Chevy needs to upgrade a pieces recently, lest people neglect the latest eight-speed outright in its disappointing visible and also tactile deficiencies.
Fortunately, everything else concerning the $1725 transmission is enhanced performed. We noted precisely the same 3.7-second 0-to-60-mph period in this type of convertible as we did on a 2014 version with the six-speed automatic; through 80 miles per hour, a recent Vette begins to pull apart, through 150 mph, this edges out a 0.7-second lead thanks at least in part to faster shift moments. A transmission’s sense and broad rate spread elevate a self-shifting Corvette feel regarding Porsche PDK dual-clutch-automatic amounts of satisfaction. Climate, Ecologically, Tour (normal), Sport, along with Track types give owners a variety for behaviors. On Track, a 460-hp V-8’s lightning-quick accelerator reaction as well as the electrically boosted steering’s increased performance blend wonderfully together with the transmission’s rev-matched downshifts and redline upshifts. Remove the red misting by switching into Tour and also Eco, and the 8L90 harmonizes with the variety of calmness.
The EPA says that while the 2015 Vette with the eight-speed nets the same 16-mpg rating on the city cycle as the 2014 model, the freeway number rises from 1 mpg on to 29. That test car’s participation in our brutal 10Best tests stifled gas mileage to a depressing 12 miles per gallon, however we’re convinced that with normal use, it could better this eighteen miles per gallon we recorded along with the old transmission.
