The 2018 BMW 4 Series Convertible is a compact convertible offered in 2 trims, starting off at a base MSRP of $51,650. For that price, it mainly competes with the Mercedes-Benz C-Class Convertible, the Nissan 370Z Convertible, and the Audi A5 Convertible. Between 2 trims, the BMW 4 Series Convertible offers 2 powertrains. The base engine is a 2.0L turbocharged inline-4 capable of making 248 horsepower and 258 lb-ft of torque. If more power is required, there is also a 322 horsepower-making 3.0L turbocharged inline-6 engine. Both engines are mated to an 8-speed automatic transmission. The BMW 4 Series Convertible reaches 60 mph from zero in 5.8 seconds on its base engine, which gets pumped up to 4.8 seconds with the inline-6 engine. Depending on the powertrain, the BMW 4 Series Convertible can manage a combined fuel economy between 25 and 27 mpg. While we’re on the topic of choices, the 16 striking colors the BMW 4 Series Convertible comes in really pull you towards itself.
