FAST FACTS
"It's all about the powertrain with the M440i Convertible. Making nearly 400 horsepower and yet capable of well over 30 mpg on the highway, the B58 turbocharged inline-6 is an engineering marvel, and it's paired with probably the best automatic transmission in the business. Sounds pretty good with the top down, too, but does it look good? That's a separate matter."—Ranked #1 out of 2 Compact Performance Convertibles

The B58 turbocharged inline-6 sounds great anyway, so if you pair it with a top that drops, all the better. Sure, it's expensive, but to us there's no contest between this machine and the four-cylinder 430i. You gotta get the six, especially for 2025, which brings a 3-mpg boost in fuel economy and a bunch more torque besides.
We have to wonder what the use case is for a 386-horsepower soft-top convertible with all-wheel drive, but hey, maybe you just want to get to 60 mph four-tenths quicker than you would with rear-wheel drive. We can respect that.
