GM, GM<\/em><\/p>\n Here\u2019s a stoplight drag race we\u2019d like to see at a future Woodward Dream Cruise: the Porsche 963 RSP vs. the Cadillac V-One.<\/p>\n At Carmel, California\u2019s summer autopalooza last week, The Quail, General Motors Co.’s luxury brand unveiled the wicked-looking V-One Concept based on the Cadillac V-Series.R hypercar that endurance-races across the globe from Daytona to Le Mans.<\/p>\n The V-One comes a little over a year after Porsche\u2019s street-legal hypercar \u2014 also based on their Le Mans endurance racer \u2014 debuted at the 2025 24 Hours of Le Mans in France. The car was gifted by Porsche to Roger Penske, Porsche\u2019s partner in international sports car racing.<\/p>\n Like the 963 RSP (short for Roger Searle Penske), the V-One is a street-focused version of the V-Series.R. The two cars are likely the fastest street-legal vehicles ever conceived. Unlike the Porsche, Cadillac hailed the V-One as a halo for future V-Series brand design.<\/p>\n
