Mechanically, the biggest addition to the 2015 Corvette is its optional eight-speed automatic, the new paddle-shift transmission we've been eagerly awaiting since it was first announced back in April. The order guide reveals that the new gearbox will come with a 2.41 limited-slip differential, which should help with traction.
Aesthetically, perhaps the biggest addition is the availability of a new ZF1 Appearance Package that features the body-color spoiler and five-spoke silver alloys from the Z51 Performance Package without the commensurate mechanical upgrades. Other new options to personalize the looks of the Corvette include available black and silver valve stems, carbon-fiber badges and a new Carbon Fiber Ground Effects Package with new front splitter, rocker panels and more aggressive rear spoiler made from the lightweight material. If you want Chevrolet to decide on the mix and match of the stylistic upgrades, buyers can specify the previously revealed Pacific Design Package or Atlantic Design Package for the coupe and convertible, respectively.
There are also two new paint colors, Shark Gray Metallic and for an additional charge, Daytona Sunrise Orange Metallic returns, replacing Lime Rock Green Metallic and Cyber Gray Metallic. Sadly, there are no photos available yet of these new colors (you're looking at a 2014 model), but at least you can also keep that new paint spotless with a clear decal kit and rear fascia protector.
Inside, the 2015 coupe will be available with a suede-quilted headliner and the convertible receives an optional carbon-fiber tonneau cover. Chevrolet's latest OnStar system complete with in-car wifi hotspot is also an option, and to get the trick Performance Data Recorder, you must spec the navigation system.
All of the details are available on the General Motors Fleet Order Guide or you can click through our gallery to check it all out. Unfortunately, there is no information about the Z06 in the guide at the moment, but we'll keep our eyes peeled.
