Supercar maker John Hennessey joins Hannah Elliott and Matt Miller to talk about what it takes to set world speed records - and he hints at plans to put one of his million-dollar, Texas-built supercars on Germany's infamous Nürburgring Nordschleife. Plus, Hennessey is considering building a restomod vehicle (Hennessey Porsche, anyone?) and going for a new world top-speed record that could hit 500km/hour.
