A mysterious, camouflaged Toyota coupe has been spotted testing on WRC stages in Portugal, fueling rumors of a 2027 GR Celica revival. The prototype, sporting Gazoo Racing’s signature livery, suggests a return to Toyota’s rally roots with a rumored 400-hp turbocharged 2.0-liter engine. If production follows, the Celica could finally bridge the gap between the GR86 and the Supra.
