What Is the 2015 BMW 640 Gran Coupe?

The 2015 BMW 640 Gran Coupe is a five-seat sports sedan that competes with the Mercedes-Benz CLS-Class, Porsche Panamera and Audi A7. It's offered in i and i xDrive trim levels, where xDrive designates all-wheel drive. The 2015 BMW 650 Gran Coupe is covered separately.

What's New on the 2015 BMW 640 Gran Coupe?

The 2015 BMW 640 Gran Coupe's standard iDrive navigation system gains a touchpad controller and a new digital instrument panel is also included. Launch control is now standard with the automatic transmission and a Harman Kardon surround-sound system is now available.

How Does the 2015 BMW 640 Gran Coupe Compare to Other Sports Sedans?

The 640 Gran Coupe outdoes many of its competitors in terms of sportiness, particularly its driving feedback. As good as the BMW feels, though, it's utterly outclassed by the driving dynamics of the Porsche Panamera.

When comparing efficiency ratings of conventional powertrains, the Gran Coupe outdoes many of its rivals. The 640 xDrive Gran Coupe offers an EPA-estimated 20/29/23 mpg city/highway/combined, which is better than the Audi A7 quattro (18/28/21 mpg), Mercedes-Benz CLS (17/24/19 mpg) and Porsche Panamera 4 (18/27/21 mpg). However, some alternative options are more efficient: The A7 is available with an optional turbo-diesel engine that offers 24/38/29 mpg, while the Panamera is offered with a plug-in hybrid powertrain that manages 25 mpg combined while also boasting the ability to operate on electricity alone for up to 16 miles.

While the BMW is outwardly larger than its competition, it unfortunately doesn't feel like it on the inside. It technically has five seats, but the fifth seat is extremely cramped, so it's better to consider this a four-seater in practice, much like the Mercedes-Benz CLS and Porsche Panamera.

What Features in the 2015 BMW 640 Gran Coupe Are Most Important?

The 640 Gran Coupe comes equipped with a 315-horsepower, turbocharged 3.0-liter inline-six-cylinder engine that's mated to an eight-speed automatic transmission. Rear-wheel drive comes standard, as do adaptive shock absorbers with driver-selectable drive modes. All-wheel drive, an active suspension and rear-wheel steering are available.

Other significant standard features include 18-inch alloy wheels, adaptive xenon high-intensity-discharge headlights, LED taillights, a navigation system, a 10.2-inch touchscreen connected to the iDrive system and a CD-equipped audio system with HD Radio capability, Bluetooth streaming audio and USB connectivity. Notable optional features include 19- or 20-inch wheels, adaptive LED headlights, BMW Individual matte paint finishes, a Bang & Olufsen premium audio system, sunshades for the rear window and rear side glass, four-zone automatic climate control, ventilated front seats and ceramic accents for the iDrive controller. An M Sport Package is also available and adds unique styling details, black chrome exhaust tips, side skirts, LED foglights, black brake calipers and 19-inch wheels.

As required in every new car, the 640 Gran Coupe comes equipped with an electronic stability system, antilock brakes and front airbags. Other standard safety features include front and rear parking sensors, side-impact airbags, active front head restraints and a backup camera. Available safety features include a blind spot warning system, lane departure warning, a surround-view camera system, a full-color head-up display and night vision with pedestrian detection.

Should I Buy the 2015 BMW 640 Gran Coupe?

The 640 Gran Coupe is significantly more expensive than rivals like the Audi A7 and Mercedes-Benz CLS, which is especially galling given that even a fully loaded model is lacking some of the more advanced safety features available. The Porsche Panamera 4's all-wheel-drive variant is more expensive than the BMW's, but it's also about 350 pounds lighter and offers a much more engaging driving experience.

The 640 Gran Coupe is eye-catching, but its interior is lacking, and it's ultimately more of a grand touring car than sports car. In this case, the BMW nameplate - like the Porsche badge - comes at a premium, and that becomes tough to swallow when you consider some of the other choices in the Gran Coupe's class.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
