Here’s a 2020 BMW M4 Convertible that I saw at Rolls-Royce Tampa Bay in January of 2020. The BMW M4 is a sports car that’s been in production since February of 2014. The coupe version was unveiled at the 2014 North American International Auto Show, and the convertible was unveiled at the 2014 New York Auto Show. The engine is a 3 liter S55B30T0 twin turbo straight-6 that produces 425 horsepower and 406 pound-feet of torque. The transmission of this one is a 7-speed dual clutch transmission. This car does 0-60 mph in 4.1 seconds and has a top speed of 155 mph. This car weighs 4,054 pounds. The starting price of the M4 Convertible is $77,650.
