BMW 4-Series Expert Review
New for 2017
For 2017, the BMW 4 Series' primary updates are to the engines, resulting in name changes: the 28i and 35i models are replaced with 30i and 40i models, respectively. Other new features include a standard Nappa leather steering wheel (440i only); new Individual paint, trim, and leather options for 440i models; new interior colors and stitching; an upgrade to an iDrive 5.0 infotainment system; with wireless phone charging and a Wi-Fi hotspot now available.
The BMW 4 Series sits in the middle of BMW's coupe/convertible lineup, sharing its core underpinnings with the 3 Series sedan range. The smaller 2 Series offers more sport-focused nature, and the larger 6 Series focuses more on luxury and refinement.
The 2017 BMW 4 Series is available in a plethora of body styles, engine, and transmission options, and drive types. Both rear- and all-wheel drive are available on most models. Coupe, convertible, and Gran Coupe (hatchback) body styles are all available in 430i and 440i powertrain configurations.
The new 430i and 440i designations denote the updated engines under the hood of the 2017 4 Series. The former 428i is upgraded to 430i badging and a more potent 2.0-liter turbocharged four-cylinder engine rated at 248 hp and 258 lb-ft of torque, an upgrade of 8 hp and 3 lb-ft of torque. The former 435i becomes the 440i with its new 3.0-liter turbocharged inline six-cylinder engine rated at 320 hp and 330 lb-ft of torque, a more substantial upgrade of 20 hp and 30 lb-ft of torque over the outgoing 435i.
Manual and automatic transmissions are offered, depending on the powertrain and model selected. A six-speed manual transmission is available only in coupe body style 430i models with rear-wheel drive, and in coupe body style 440i models, but with both rear-drive and xDrive all-wheel drive. Convertible and Gran Coupe models are only offered with an eight-speed automatic transmission (also available on coupe models).
An M4 variant is also available, offering 425 hp and 406 lb-ft of torque, a heavily upgraded suspension and chassis, and other performance-oriented upgrades.
Gas mileage varies across body styles and engines, with the rear-drive 430i coupe models all scoring 23 mpg city, 34 mpg highway, and 27 mpg combined when combined with the automatic transmission; the manual, rear-drive 430i coupe rates slightly worse at 21/33/25 mpg city/highway/combined. If you opt for all-wheel drive on your 430i, the coupe and Gran Coupe models offer EPA ratings of 23 mpg city, 33 mpg highway, and 26 mpg combined; the 430i convertible with xDrive rates 22/32/26 mpg. The 2017 BMW 440i models have EPA ratings of 19-21/29-32 mpg, depending on transmission, body style, and rear- or all-wheel drive.
Neither the National Highway Traffic Safety Administration (NHTSA) nor the Insurance Institute for Highway Safety (IIHS) have released crash test ratings for the 2017 BMW 4 Series.
What We Think
Lower and wider than the 3 Series it's based on, the 2017 BMW 4 Series is designed to be a sportier alternative to the beloved sedan. Fortunately, the 4 Series lives up to its intent, offering inspired handling and ample power in all configurations.
It's also a more design-driven option, with coupe, convertible, and Gran Coupe body styles drawing new themes from the core platform. Despite the largely successful visual differentiation from the 3 Series, even a fully loaded 4 Series lacks a certain feeling of "specialness."
The 2017 BMW 4 Series Gran Coupe takes all the fun of BMW's 4-Series (and closely-related 3 Series and wraps it up in a fun and practical hatchback body style.
