Not really a surprise. The World-Challenge was not competitive against the GT3 machinery on the grid. It was really the only choice.What a very nice surprise !! In the GT3 format they are bound to find a group of new customers/sponsors now the world will be their customers, and we will see another GM brand racing internationally. And it will be competition for the new Callaway built C7 GT3 version now delayed to 2016.......???
To me this is a very big deal, with 2 all new race versions for GM to build and promote.
That'd be like saying Porsche won't make a 911 Turbo because the GT3 is normally aspirated.The fact that they race the TTV6 means there will be no V+ with a V8
It just means GM is more confident they can make more power from a smaller Engine than BMW and they already have the Callaway GM powered V8 GT3 Corvettes.. which interestingly have not switched over to direct fuel injectionWhat's also interesting is that BMW went with the M6 as their next GT3 spec car. They didn't want to race the twin turbo in-line six and felt the twin turbo V8 is better. We'll see.http://www.roadandtrack.com/racing/racing-news/bmw-m6-gt3-announced
