According to
RTCC the Plus 4 Supersport has a 2.0 variable cam engine. I guess this means that the engine is the Ford 2.0 liter DI Ti-VCT (direct injection, twin variable cam timing). The stock engine has 155 hp and 196 Nm of torque and is flexifuel capable. Perhaps this limited edition is a preview of the standard +4 2012 models?
