Is Gen 7 seriously considering the V8 Supercars regs? Are they trying to reinvent the wheel?
The regs in Australia call for 5L engines (305.1187 cid) and the racing Chev engine works out to be 305, while the Ford is a 302 Windsor derivative. Also, because the rear wing is higher up. cars follow each other nose to tail. There is already plans by Walkinshaw-Andretti to bring the Camaro to Oz, and the Mustang as pictured here was DJR Penske.
Already that gives you Mustang, Buick Regal, Nissan Altima as exisitng cars; I can imagine that Roger Penske will probably want to rent the IP as well.
Coyote is mostly a horrible engine to go racing with; so I imagine that FoMoCo America would run with the tried and tested Windsor.
