2015 BMW Alpina B6 XDrive Gran Coupe Side View
Five p.m., Friday afternoon, Munich airport parking lot. I’m handed the keys to the BMW Alpina B6 Gran Coupe. At 5:06, I’m doing 140 mph on the autobahn.
Oh, the glories of Germany, the only place in the world where the highway to an international airport often has no speed limit. It’s also a place where a grand-touring car like the B6 makes stupendous sense.
By 5:25 p.m. I’ve made two conclusions: 1) I’m not sticking around Munich, but am heading to the Austrian Alps, and 2) This may be the most capable car I’ve ever driven on the autobahn. By weekend’s end I’ll also come to another: The Alpina B6 is the best version of BMW’s 6 Series sold today.
Alpina Burkard Bovensiepen GmbH is officially an independent car company, but all BMW Alpina models are manufactured in a BMW plant and then hand-finished by Alpina in Buchloe, about forty-five minutes outside of Munich. You might break down the company’s philosophy in two salient points: The best of everything, only with lots more torque.
Alpina sells a number of models in Europe, but in recent times we’ve only been offered the B7 in the United States, a well-optioned, higher-torque version of the 7 Series. (BMW North America hasn’t been keen to invite in-house competition with its own M cars, so we don’t get the Alpina 3 Series, for instance.) The B7 is a nice car, no arguments, but it falls short of being an argument-ending reason to choose the Alpina over the twelve-cylinder 760Li or even a nicely optioned 750i xDrive.
The B6, on the other hand, is something special. Based on the lovely four-door version of the 6 Series (misleadingly named the Gran Coupe), the $118,225 Alpina gains standard all-wheel drive and a retuned engine, transmission, and electronics. The 4.4-liter, bi-turbo V-8 makes 540 hp and 540 lb-ft of torque.
The B6’s most obvious competitor is the $115,300 M6 Gran Coupe, with the same engine but slightly different output (560 hp and 502 lb-ft of torque) and rear-wheel drive. The B6 has 20 fewer horses but 38 foot-pounds of extra torque. It’s not a sports car anyway, so the tradeoff provides the grunt that drivers will find most useful while pounding away from a stop light (0 to 60 mph in 3.7 seconds) or making power passes on the freeway. I exulted every time I saw the autobahn-specific sign of a circle with three lines marked through—i.e., no speed limit. The car slips from 75 mph to 135-plus in moments. Top speed is 198 mph when equipped with Michelin Pilot Super Sport performance tires, though I never got a clear enough stretch to test it.
The Gran Coupe has a feminine shape, and when it’s all dressed up in as an M model with a carbon-fiber roof and an exaggerated front end, it looks a bit like Kate Upton in bondage gear. By comparison, the Alpina’s restyled fascia, rear diffuser, and double tailpipes add a touch of attitude without taking away from the pretty lines. The nose includes a subtle carbon-fiber front splitter, which will be body-colored in the States. Alpina execs say exterior changes are functional and in service to the top speed or efficient cooling. My car was the very first finished B6 off the production line, and it was painted Alpina blue. (Green is the other Alpina-specific color.) It also had Alpina’s traditional 21-spoke wheels.
The interior on my test model was top-of-the-line BMW, including plush Merino leather. Alpina’s own special hide isn’t offered in the U.S., but we do get a steering wheel coated with the fabulously soft stuff, with blue and green stitching. Interior alterations include Alpina aluminum doorsills and distinctive blue-hued gauges.
The significant changes are all under the skin: reworked engine mapping and altered gear ratios, extra cooling capacity, a retuned exhaust system and a tweaked division of torque on the AWD system. There is no specific torque split, the Alpina guys say, but it consistently skews significantly to the rear, a truth you can feel on the move. The tuning of the ZF eight-speed transmission deserves a special call-out. The car is always in the right gear, and kick-downs are instantaneous yet never jarring. The systems are gorgeously mated: Ask for power and it translates to smooth, right-now, forward movement. The sum of the parts is a grand-touring dynamo that feels more special than any BMW I’ve driven in recent memory. It’s more refined and sensible than the M6, and makes the regular 6 Gran Sport seem downright frumpy.
I was headed to Salzburg, which would maximize autobahn miles. However, the quick changes of speed limit can be bewildering: The nav system and a forward camera kept better track of them than I could. The speed limit is then beamed onto the head-up display. Brilliant. Like all 6 Series cars, however, the Alpina is hampered by awful sight lines; the A-pillars are fat and the wide rounded fenders are impossible to see. You’ll live in terror of brushing them against walls in tight parking garages or curbing tires on the street.
It began raining, varying from annoying drizzle to windshield-obscuring downpours. Temps were in the 40s and 50s, which gave me some concerns about the performance tires, but traction was sure throughout. (Later, in a wet parking lot, I turned systems to sport plus and horsed around. I could get it to power slide, but only after serious coaxing. The considerable torque is well curtailed.)
The Alpina’s other distinction is the chasm between driving modes. Comfort plus is far more plush than the comparable mode in a regular 6, while the max sport setting amps up response times considerably. Comfort plus was too lazy for my taste; the electrically adjustable dampers smother road imperfections but the steering becomes disturbingly lax. Sport is just the right amount of firm without being too harsh, and you can point the big car down the road with precision.
After finding a hotel in Salzburg (and discovering you can’t park within the old section at all—you’ll have to haul your bags), I sated myself with Wiener Schnitzel and local brews. The mountains were cloaked in clouds in the morning, and I chose the tiny hamlet of Hallstatt, on Lake Hallstatt, as a lunch destination. Snaking roads followed rivers running white with overflow. After I realized that the B6 wasn’t going to snap out from underneath me, even in the wet, I changed the settings to sport and had a good time.
Sunday evening, 375 miles on the odometer, I was back in Germany. I returned the B6 to the Alpina factory in Buchloe. They’d shown me just how good a 6 Series can really be.

New for 2015

The 2015 BMW 6 Series line gets minor changes and the Alpina B6 xDrive Gran Coupe is introduced -- a milestone because BMW’s own M division doesn’t (yet) offer all-wheel-drive cars with lots of power. The 6 Series sees minor changes for the 2016 model year.

Vehicle Overview

The BMW 6 Series comes in coupe, coupe-like four-door (Gran Coupe), and convertible forms, fitting above the 4 Series coupe, convertible, and four-door hatchback as the automaker's most expensive two-doors underneath the i8 supercar.


The 2015 BMW 6 Series is powered by a quartet of engines, each with its intended audience or niche. From the attractive Coupe, to the fun convertible, to the versatile Gran Coupe coupe-like four-door, all the way to M6-based models, and even further to high performance Alpina B6 xDrive Gran Coupe.

Engine and Transmission: Turbocharged 3.0-liter I-6 – eight-speed auto

Engine and Transmission: Twin-turbocharged 4.4-liter V-8 – eight-speed auto
Power: 445 hp/480 lb-ft
EPA-rated fuel efficiency: 17/25 mpg (coupe, convertible, Gran Coupe) – 16/25 mpg (coupe xDrive) – 16/24 mpg (convertible and Gran Coupe with xDrive)

Engine and Transmission: Twin-turbocharged 4.4-liter V-8 – seven-speed auto or six-speed manual

Some of the most notable features on the 2015 6 Series include LED headlights, active blind spot detection, full color head-up display, lane departure warning, pedestrian & collision warnings, a Bang & Olufsen premium audio system, an available night vision system that aids in pedestrian/animal detection, and a parking assistance system that will steer the 6 into a parallel space.
The 2015 BMW 6 Series has not been evaluated by the NHTSA or the IIHS.

What We Think

The 2015 BMW 6 Series comes in coupe, convertible, or coupe-like four-door forms, and seeks to provide a balance between sport and luxury. Much like the 8 Series from years past, the 6 Series is a lavishly appointed two-door touring car that is as comfortable at 150 mph as it is around town. The interior appointments set the bar for BMW interiors, and we noted in an Editor’s Notebook review of a 2012 650i Coupe that “all the materials look and feel expensive,” something you would hope was present in a vehicle whose price can crest $100,000. One downside to the 6 Series, indeed many BMW models, is the way they can get pricey in a hurry with options.
We suggest passing on the turbocharged 3.0-liter I-6 (640i models) on account of the performance, as we noted in a Driven review of a 2014 640i Gran Coupe, “Its 315-hp, 3.0-liter turbocharged I-6 is powerful enough, but the 640i Gran Coupe lacks any real urgency or excitement.” Opting for any variant of the twin-turbo V-8 solves that problem (650i, M6, Alpina B6), as in an Editor’s Notebook review of a 2012 M6 Convertible we said, “[the M6 Convertible] feels like a (recent) BMW M car: an otherwise heavy car that bends physics and delights passengers.”
Speaking of passengers, the M6 Gran Coupe is a more stylish M5, but with a much improved interior for four. In our Driven review of a 2014 M6 Gran Coupe at the Circuit of the Americas in Texas, we noted that “it will lap racetracks faster than any other BMW production car, including the vaunted M3.” The Alpina B6 xDrive Gran Coupe is the best of the 6 Series bunch if touring is your aim, and as we noted in a Driven review of a 2015 Alpina B6 xDrive Gran Coupe, “It’s more refined and sensible than the M6, and makes the regular 6 Gran Sport seem downright frumpy.”
6 Series Gran Coupe and M6 Gran Coupe compete with the Audi A7 and Mercedes Benz CLS-Class (and their high-performance variants); all vehicles that overlap their four-door platform mates but deliver “decked-out interiors,” sloping rooflines, and that coupe-like four-door look. Does the 6 Series make financial sense over a similarly-equipped 5 Series? No, but as with other popular coupe-like four-door luxury cars, style is the name of the game, something the 6 Series line does well.

2015 Dodge Charger SRT Hellcat Front Three Quarters Top View
Enthusiasts might love useful wagons, sporty coupes, open-air convertibles, and capable off-roaders, but sedans are still the go-to choice for buyers in the U.S. Make no mistake though, not all four-doors are doomed to grocery toting and commuting. Some sedans beg for more. Some sedans have an appetite for asphalt and a mean streak to boot. These top ten most powerful sedans you can buy here in the States can do it all, from laying down hot laps at the track to picking up the kids from school. Dive in and you'll see the ten most powerful four doors in their standard condition--that means no special tunings or performance packages that are added on at a premium.
