For the first time in 50 years, there will be two distinct Shelby Mustang models available for sale by the end of 2019. While the new supercharged GT500 will arrive this fall, Ford is keeping the GT350 in the lineup with some fresh updates designed to make it both a better performer and a better all-around sports car. Ford recently rented the Champion Motor Speedway north of Detroit for a day of lapping in the 2019 GT350.
