The 2021 BMW 4-Series Convertible has just been unveiled, some 35 years after the first 3-Series Convertible was released.
The key difference between this new 4-Series Convertible and the model it replaces is that the 2021 now features a soft-top whereas the previous-generation car had a heavy hardtop.
The new looks extend to the roof which is now a soft-top instead of a retractable hard-top like on the previous generation. The simpler, sleeker soft-top not only improves the way the 4-Series Convertible looks but also makes it lighter and takes up less space both when stretched over the cabin and folded in the trunk. BMW said the soft-top is approximately 40% lighter than the previous generation’s hard-top. It also results in 0.2 inches of extra headroom in the cabin when up, and 1.2 cubic feet of extra storage in the trunk when folded.
The roof can be opened and closed in 18 seconds at speeds of up to 31 mph (50 km/h). Cargo space has been increased to 9.0 cubic feet (255 liters), an increase of 1.2 cubic feet (34 liters) over the previous-generation 4-Series Convertible.
The engine range carries over from the 4 Series coupe. The 430i uses a turbocharged 2.0-liter four-cylinder that makes 255 horsepower (190 kilowatts) and 295 pound-feet (400 Newton-meters). The rear-drive droptop reaches 60 miles per hour (96 kilometers per hour) in 5.9 seconds. Depending on the wheel and tire combination, the top speed is limited to 130 mph (209 kph) or 155 mph (249 kph).
The M440i has a 3.0-liter turbocharged inline-six engine with 48-volt mild-hybrid technology that produces 382 hp (285 kW) and 369 lb-ft (500 Nm). The rear-drive model hits 60 mph in 5.0 seconds. Like the other model, the top speed is limited to 130 mph (209 kph) or 155 mph (249 kph), depending on which tire-and-wheel combo the buyer selects.
Both engines come with an eight-speed automatic. The M440i also benefits from a standard M Sport rear differential, and it’s optional on the 430i.
The 2021 BMW 4-Series Convertible starts at $53,100 for the 430i, $55,100 for the 430i xDrive, $64,000 for the M440i, and $66,000 for the M440i xDrive. These prices exclude a $995 destination charge.
