The BMW 7-Series is a full-size luxury sedan that’s considered to be the benchmark for standards in the large sports sedan class. The 7-Series comes with a variety of drivetrain choices, including the economical inline-six engines to the more power V-12s, but the V-8s are the most common for 7-Series in the U.S. Since some 7-Series cost more than $150,000, it can be optioned to be the most expensive BMW. It competes with other large luxury sedans, like the Lincoln LS, Jaguar XJ, Mercedes-Benz S-Class, and the Audi A8.
See our 2014 BMW 7-Series review for pricing with options, specifications, and gas mileage ratings.The first 7-Series was introduced in 1977, and was sold through the 1986 model year. A large, roomy four-door, the "7er" came to America in three versions: 733i, 735i, and L7. The U.S. versions were outfitted with power features, leather and wood trim, and a sunroof, as well as bigger bumpers, and marketed as luxurious competitors to the most expensive Mercedes four-doors. Some versions of the European-market, turbocharged 745i were sold in the U.S. in the grey market--technically not illegal but not imported by BMW itself. The L7 was a version of the 735i fitted with more leather trim and more standard features, as well as an automatic transmission and a driver-side airbag--making it the first vehicle sold in America with that safety feature.
With the second-generation 7-Series, which was sold from 1987 to 1994, BMW added a new engine variant. The 730i sported a 3.0-liter in-line six; the 735i carried on with its 3.5-liter in-line six; and the new 750i arrived with a 300-horsepower V-12 under its hood. The new sedan's styling was more sleek and yet still dynamic, with the quintessential BMW twin-kidney grille tilted forward at the front and inside, a functional--almost austere--cockpit that still featured a manual gearbox on some versions. An "L" version added length to the wheelbase, and late in life the 7-Series gained a new 3.0-liter in-line six and a 4.0-liter V-8.
In the third generation, which ran from 1994 to 2001, BMW watered down the car's styling to near-anonymity. The six-cylinder engine was discontinued, leaving behind a 740i and a 740Li model with a 4.0-liter V-8 (later upgraded to 4.4 liters) and the V-12-powered 750Li. A five-speed automatic was featured, and some mild facelifts accompanied the car through the end of its model run in 2001. This 7-Series also made a start turn, in the 1997 James Bond film Tomorrow Never Dies.The fourth-generation 7-Series changed dramatically, and with that change came controversy. This 7-Series, sold from 2002 to 2008, brought with it a radically "flame-surfaced" style that was said to have been a response by chief designer Chris Bangle to a BMW board demand that their cars become more expressive. Expressive they were, but critics contended the high roofline, big glass areas, and oddly tiered styling didn't work well, and disrupted the company's focus on "ultimate driving machines." BMW would go on to sell more of this generation 7-Series than any before, but sales grew thanks to expansion in new markets, particularly China. Over its lifespan, this generation would include short- and long-wheelbase variants, rear- and all-wheel-drive versions, but no manual-gearbox versions.
Perhaps the most disliked feature of the new 7-Series was iDrive. BMW pioneered the round controller on the center console, and intended it to take the place of dozens of buttons and switches in its cockpits. iDrive proved difficult for many users to master, even with haptic feedback and a large LCD screen for navigation. Changing radio stations could be an exercise in frustration; even redundant voice controls for the car's navigation system proved to be a hurdle. Widespread dissatisfaction with both the car's styling and iDrive didn't temper enthusiasm for its handling nor for its brisk acceleration, however. In 2006 BMW uprated the V-8 engine to 4.8 liters and 360 horsepower, and changed the car's nomenclature to 750i / 750Li. It had boosted the V-12 to 6.0 liters and 438 hp in 2004, making it the 760Li. In 2007 it reintroduced an Alpina B7 with the 4.4-liter V-8, without output rated at 500 hp.
In 2009, BMW introduced the current version of the 7-Series. With a revamped look that greatly muted the prior car's humps and crests, the new car turned out much more attractive, particularly inside, where iDrive lost the battle to control every function, and the dash was clarified into a more logical, handsome piece. The iDrive system itself received an entirely rethought, more logical action, with intuitive icons, plus more redundant buttons that "bookmarked" settings for audio, climate, and navigation--whatever the driver's preference. Performance came from a range of V-8 engines for the first model year, with a six-speed automatic the norm in the 750i and long-wheelbase 750Li; in the 2010 model year, BMW added six- and twelve-cylinder (735 and 760) versions, as well as a hybrid teamed with lithium-ion batteries, and new all-wheel-drive versions--and wait, there's also a new Alpina edition. The V-12 version brought with it a new eight-speed automatic transmission, which is expected to make its way through the lineup in due course. A bulletproof version can be ordered, and BMW has long experimented with hydrogen-powered 7-Series sedans--though none has been offered for sale.
The 2013 BMW 7-Series lineup received an extensive mid-cycle refresh. While the exterior design didn't change significantly (a new grille and front fascia was the most noticeable part), the 2013 7-Series sedans packed next-generation turbocharged V-8 engines in the 750i variants, plus xDrive all-wheel drive offered on most of the lineup and an eight-speed automatic for the entire lineup--with both power and fuel economy figures rising for all of these models. Bang & Olufsen premium audio system arrived for these models; iDrive received a revised menu structure and voice-command system, while the navigation system offered faster rendering and 3D maps.
A new generation of 7-Series sedan is expected sometime around the 2015 model year. An effort toward lighter curb weight is expected, as BMW learns how to put carbon fiber into more mainstream vehicles via its i8 and i3 electrified cars. The new 7-Series could also gain a new ultra-luxury model, just as the Benz S-Class will--as a bridge model to the Rolls-Royce Ghost, also engineered in part by BMW, the parent company of the British automaker.
