What's New for 2015

The 2015 BMW 4 Series Gran Coupe is an all-new model.


It's fair to admit some puzzlement over a BMW 4 Series with four doors. After all, BMW rebranded its two-door 3 Series as the 4 Series just last year. So why call this a 4 rather than a 3? The 2015 BMW 4 Series Gran Coupe also shares the same length, wheelbase and width as the two-door, contributing to the confusion.

Then again, BMW has a knack for creating niches that don't exist. In the case of the 4 Series Gran Coupe, it's a coupe in name only, as it does indeed have four doors. It's fair to say that this new four-door is better-looking than the 3 Series sedan, as it sports the 4 Series' lower, slightly wider and more aggressive-looking stance. And instead of a trunk, the Gran Coupe offers a hatchback-style liftgate that enhances cargo loading ease and versatility.

The Gran Coupe doesn't differ under the hood, though. The 428i model offers the same, surprisingly powerful 240-horsepower turbocharged four-cylinder found in other BMW 28i models, while a turbocharged six-cylinder finds its way into the 435i. A standard eight-speed automatic transmission wrings the most performance and frugality out of either engine and features steering wheel paddles if you want to shift it yourself.

Given its unique style and dimensions, the 2015 BMW 4 Series Gran Coupe has no real direct competitors. Compact coupelike sedans like the Audi A3 and Mercedes-Benz CLA-Class are a full class smaller than the Gran Coupe. Really, the Gran Coupe's true competitors are within its own family. With its rear hatch opening and abundant cargo space it's more practical, though also more expensive, than a 3 Series sedan. As such, it may be a tempting alternative to the 3 Series wagon for those who want added cargo capacity without the wagon stigma. However, it offers much less room than the 3 Series Gran Turismo, although it also does without that car's gawky styling.

It's a thinly sliced difference to be sure, but if you desire a dash of style with a sensible side of utility, then the 2015 BMW 4 Series Gran Coupe is a niche vehicle worth consideration.

Body Styles, Trim Levels, and Options

The 2015 BMW 4 Series Gran Coupe is a five-passenger, four-door hatchback styled as a coupe. It is offered in two primary trims: 428i and 435i.

Standard equipment on the 428i Gran Coupe includes 17-inch wheels, a sunroof, adaptive xenon headlights, foglights, rain-sensing wipers, a power liftgate, auto-dimming side and rearview mirrors, a sunroof, leatherette (premium vinyl) upholstery, eight-way power front seats, driver memory settings, dual-zone automatic climate control, a 6.5-inch display screen, BMW's iDrive electronics interface, Bluetooth phone and audio connectivity, BMW Assist and a nine-speaker sound system with a CD player, a USB/iPod interface, an auxiliary audio jack and HD radio.

The 435i is equipped similarly, but comes with a more powerful engine and 18-inch wheels.

Several option packages are available to help customize the 4 Series Gran Coupe. Three optional equipment lines -- Luxury, Sport and M Sport -- include unique wheel designs (18- and 19-inch diameters), color schemes and trim and upholstery types. The Sport and M Sport also include summer performance tires, performance-tuned suspensions and 10-way front sport seats. The M Sport goes further, adding aerodynamic enhancements and a sport steering wheel.

The Premium package equips the Gran Coupe with a hands-free power liftgate (works by swiping a foot under a sensor in the rear bumper), leather upholstery, four-way power front seat lumbar settings, keyless entry and ignition and satellite radio. The Technology package adds a navigation system with an 8.8-inch display screen, a touchpad iDrive controller, a head-up display, BMW Apps (allows control of smartphone apps including Pandora, Stitcher and Facebook) and BMW Remote Services.

LED headlights and automatic high beam control are available in the Lighting package, while a Cold Weather package adds heated front and rear seats, and a heated steering wheel. The Driver Assistance package adds a rearview camera and front and rear parking sensors, and can be enhanced with the Driver Assistance Plus package, which adds blind-spot monitoring, lane departure warning, frontal collision warning and mitigation, and a side- and top-view camera system.

Finally, the Dynamic Handling package enhances the car's performance with adaptive suspension dampers and variable-ratio sport steering.

Several of the features listed above can be ordered as stand-alone options. Other individual options include upgraded brakes, adaptive cruise control, automatic parallel parking assist and a 16-speaker Harman Kardon surround-sound audio system.

Powertrains and Performance

The 2015 BMW 4 Series Gran Coupe offers two engine options, both paired with an eight-speed automatic transmission (a manual transmission is not available). Rear-wheel drive is standard, and all-wheel drive (denoted as "xDrive") is optional. Initially the 435i will offer only rear-wheel drive, although an all-wheel-drive option is expected to debut later in the model year.

The 428i uses a turbocharged 2.0-liter four-cylinder that makes 240 hp and 255 pound-feet of torque. It is EPA-rated to return 27 mpg combined (23 city/34 highway) with rear-wheel drive and 26 mpg combined (22/32) with all-wheel drive. Going with the 435i gets you a turbocharged six-cylinder that generates 300 hp and 300 lb-ft of torque, and returns an EPA-estimated 25 mpg combined (21 city/32 highway) with rear-drive.


The 2015 BMW 4 Series Gran Coupe comes standard with antilock brakes, traction and stability control, front side airbags, side curtain airbags and front knee airbags.

The stability control system integrates several features designed to improve braking performance, such as periodically wiping the brake rotors dry when the windshield wipers are in use and automatically snugging the pads to the rotors when the driver abruptly lifts off the gas pedal. BMW Assist emergency communications is standard and includes automatic crash notification and roadside assistance. The optional Remote Services adds stolen vehicle recovery, remote door unlocking and use of the BMW Remote smartphone app.

Other safety options (many of which come bundled in packages) include parking sensors (front and rear), a rearview camera, side- and top-view cameras, blind-spot monitoring, a lane departure warning system, frontal collision warning, automatic braking for frontal collision mitigation and an automated parking system.

Interior Design and Special Features

The 4 Series Gran Coupe might be new, but its cabin is instantly familiar as a classy and premium 3 Series design. The company's classic analog sport gauges link to BMW's storied heritage, while the Luxury, Sport and M Sport offer plenty of range to tailor the cabin to your taste.

The standard 6.5-inch display screen that interfaces with the Gran Coupe's technology and entertainment functions is adequate, but you'll want the larger, optional screen for a true luxury electronics interface. The iDrive system continues to evolve throughout the BMW lineup and now includes a touchpad atop the dial controller that lets you hand write inputs using your finger. The iDrive system features straightforward menus, crisp graphics and quick processing times, but it typically requires a few more clicks and twirls to get what you want compared to rival systems.

The Gran Coupe's neatest trick is that it offers coupelike proportions and styling -- a sleek, sloping roof line and short front and rear bumper profiles -- with much of the utility of a sedan and hatchback. That handsome roof line does reduce rear headroom compared to the sedan, but BMW has also lowered the rear seat height to compensate -- the result is that a pair of normal-sized adults can still be pretty comfortable in back. The Gran Coupe's rear hatch opens to 17 cubic feet of cargo space, according to European volume measurements (EPA volume measurements, which differ from European spec, are pending). Folding down the 40/20/40-split folding rear seat greatly increases cargo space.

Driving Impressions

We haven't yet driven the 2015 BMW 4 Series Gran Coupe, but we expect its dynamic character to fall somewhere between the standard 3 Series sedan and the more performance-oriented 4 Series coupe. The Gran Coupe shares its dimensions with the regular coupe model in key areas. It is also just 0.5 inch taller than the coupe (1.6 inches shorter than the sedan) and as such we expect it to offer similar enjoyment behind the wheel when the road bends. We'd also expect it to ride more stiffly than the sedan but more smoothly than the coupe.

There will be no shame in choosing the 428i, which gave little indication of being the "base" model when we tested the coupe version. The 428i should deliver nearly identical performance for thousands of dollars less. That turbocharged four delivers remarkably quick acceleration as well as engaging engine and exhaust sounds that will have you winding through the gears for the aural thrill of it.

Despite a traditionalist's yearning for a manual transmission, we doubt you'll miss it. Our testing found that the eight-speed automatic works exceptionally well in both normal (fully automatic) driving mode and manual mode, with the driver working the paddle shifters.
