A competition between high-performance cars has taken place, with the Corvette ZR1 reportedly beating the Mustang GTD and Porsche 911 GT3 RS at Sonoma. However, other reports suggest the Mustang GTD may have outperformed the Corvette ZR1X at the Nurburgring, with some outlets indicating the Mustang GTD achieved a record-breaking lap time. The outcome of the competition appears to be uncertain, with conflicting results reported at different tracks.
