Overall 2015 information:
* Dealers expected to receive 2015 order books late May. Pricing and allocations for StingRay expected in early June — though so e believe pricing will be the last week of May with the order books. Some believe that GM will start receiving, but not acting upon 2015 StingRay orders in late May; that remains a non-confirmed rumor at this time; almost all believe that GM will not take any action on orders prior to June 26th. No date yet for dealers to receive their StingRay allocations — though many are thinking early-to-mid June.
* Z06’s, as noted before, are on a completely separate, and much later timetable; expected approximate end of August/September timeframe for dealers to receive their Z06 order books and separate Z06 allocations — with orders going in afterward. Very first customer Z06 coupe deliveries very, very end of 2014, full production in first quarter 2015; Z06 convertibles are expected to start deliveries start of 2nd quarter, 2015. This tiered Z06 production delivery schedule will mandate, at least at the beginning, separate Z06 allocations for coupes vs. convertibles.
* Software updates will no longer require visits to your dealer, but will be electronically sent to you car.
* If Dash trouble light on, it will show exactly what that symbol means on your 8″ center LCD display screen.
* All StingRay and Z06 options were previously divulged or are listed below, i.e., no further, “new for 2015 options” forthcoming.
* 2015 StingRays and Z06’s share identical ten exterior colors.
2015 StingRay Specific Changes:
* 3LT contains both IWE and PDR , though PDR available for 1LT and 2LT interiors if nav system ordered; thus, another change, you can get a 1LT ’15 and get nav system; not confirmed but many believe that unlike the 3LT option, that if you get a 1LT or a 2LT, you can order a nav system without having to also get (pay for) the PDR system.
* Carbon flash badging an option (EYT);
* Shark Gray Exterior Vents available (EXF), as are Body-Colored Exterior Vents (EFY);
* Convertible has optional real carbon fiber tonneau inserts (E57);
* NPP included with all Z-51’s;
* OnStar 10.0 with 4G/LTE (Standard)
* If select black carbon fiber aero components on stage 2 or 3, black is “glossy.”
* Guage Cluster Additions: MPH can be shown on “Tour”; Instantaneous HP on “Sport”;
* Z-51 additionally can show eLSD instantaneous status, as well as “wheel slippage” info;
* Z-51 option package will mandatorily contain NPP for 2015;
* Color changes (previously noted) include “Shark Gray” replacing Cyber Gray; and,
“Daytona Sunrise Orange” replacing Lime Rock Green BUT “delayed availability”. When shown the following picture (thanks Manuel Carrillo III), Harlan Charles said the new Daytona Sunrise Orange Metallic was a little lighter, a little brighter than the following picture.
