In 2012, Toyota approached BMW with a proposal for a joint development effort for a new sports car that would replace the venerable and beloved Supra MK4 which was retired from production in 2002. After several years of design, development and testing, the Toyota Supra MKV was launched in 2019 to mixed reviews but everyone agreed that it was a balanced drivers car.
