2021 BMW 4-Series

The 2021 BMW 4-Series has been fully redesigned for the model year, ushering in the second generation of the coupe and convertible. Unlike last year, the new 4-Series convertible features a soft-top roof instead of a retractable hardtop.

While the 4-Series has always been a favorite in the compact luxury class, the all-new design brings a front end that's quite unique. BMW’s new kidney grille dominates the front and gives the model a more aggressive look than before. Looks tend to be a subjective thing, but the 4-Series is polarizing enough to turn some shoppers away. We recommend taking a long, hard look before purchasing one.

The 4-Series is available in two trim levels: 430i and M440i. Pricing starts at $46,595 including destination for the 430i and reaches $59,495 for the M440i. The convertible variant costs an extra $6,505 (430i) or $5,500 (M440i).

The M4 is covered separately on our website.

The 4-Series borrows the same new engines found on the recently redesigned BMW 3-Series, which should come as no surprise. The 430i is powered by a 2.0-liter turbocharged four-cylinder, while the M440i features a 3.0-liter turbo six-cylinder.

An eight-speed automatic transmission is included with both engines. Rear-wheel drive is standard, with BMW's xDrive all-wheel-drive system available for $2,000. The convertible is only available with RWD.

Both the 4-Series coupe and convertible have seating for up to four people. It isn’t the most spacious sports car on the market, offering just 12 cubic feet of cargo space in the coupe and 9 in the convertible.

The 4-Series comes standard with forward collision warning, automatic emergency braking, lane departure warning, blind-spot monitoring, and traffic sign recognition. BMW also includes its Active Protection System that prepares the vehicle for an imminent crash.

More features are found in the available Driving Assistance Professional Package ($1,700). This bundle includes adaptive cruise control, lane keeping assist, pedestrian detection, a semi-autonomous system for highway use, and a system that can bring the vehicle to a stop in case of a medical emergency. The $700 Parking Assistance Package adds a surround-view camera and parking sensors.

BMW increased the amount of standard tech found in the 4-Series for the 2021 model year. Every trim comes with an 8.8-inch touchscreen running the automaker's lastest iDrive 7.0 infotainment software. Bluetooth, navigation, two USB ports, over-the-air updates, satellite radio, and Apple CarPlay and Android Auto integration are all standard.

The available $3,200 Premium package adds BMW’s Live Cockpit Pro system, which includes a 10.25-inch touchscreen and a fully-digital 12.3-inch instrument cluster. A head-up display is also included with the package, but it's also available on its own for $1,100.

Other standalone options include the 12.3-inch gauge cluster ($950), a Harman Kardon audio system ($875), and a wireless phone charger and wi-fi hot spot capability ($500).

The 430i trim comes well equipped with 18-inch wheels, heated and power-folding exterior mirrors, synthetic leather upholstery, and wood trim. A 10-speaker audio system, automatic climate control, 10-way power front seats, and an auto-dimming rearview mirror are also standard.

There are three major packages for the 430i. The Convenience Package ($900) adds remote keyless entry, ambient lighting, and lumbar support for the front seats. The Premium Package ($3,200) builds on that and adds heated front seats, a heated steering wheel, ambient lighting, the head-up display, and the 12.3-inch digital gauge cluster. The Executive Package ($4,400) combines the other two and adds adaptive LED headlights and gesture control.

There are a variety of available standalone features, like a drive recorder ($100), a heated steering wheel ($190), a power trunk ($250), heated front seats ($500), ventilated front seats ($350), an adaptive M suspension ($700), and M sport brakes ($650).

The M440i comes with the more powerful six-cylinder engine, an M sport differential, variable sport steering, M sport brakes, an M sport suspension, 18-inch M wheels, an M rear spoiler, an aerodynamic body kit, and remote keyless entry as standard.

The Premium ($2,500) and Executive ($3,700) packages are available again. Red brake calipers are a no-cost option.
