BMW has announced the 2015 M4 Convertible will be priced from $73,425 when it goes on sale in the United States this summer.

Set to debut at the New York Auto Show, the M4 Convertible will cost $8,300 more than the M4 Coupe which starts at $65,125. While the convertible comes with a hefty premium it features a retractable hard top that can be lowered in 20 seconds at speeds up to 11 mph (18 km/h).

However, the most important feature is a 3.0-liter TwinPower Turbo six-cylinder engine that develops 425 bhp (317 kW) and 406 lb-ft (550 Nm) of torque. It enables the car to accelerate from 0-60 mph in as little as 4.2 seconds - when equipped with the optional seven-speed M Double Clutch Transmission - and hit an electronically limited top speed of 155 mph (250 km).

Note: Both prices include a destination and handling fee
