BMW 7 series E23 (1977– 1986)
The first generation BMW 7 series models offered were the BMW 725i, 728, 728i/iS, 730, 730i, 732i, 733i, 735i, 745i Turbo, 745i South Africa, and L7.
BMW 7 series E32 (1987-1994)
The BMW E32 was introduced in 1987 as the replacement second generation BMW 7 series, with the 730i and 735i featuring 3.0l and 3.5l straight-6 engines respectively, and a new, 5-liter, 300 horsepower V12 engine for the 750i. In 1992, 3.0l and 4.0l V8 BMW engines were added to the lineup (730i and 740i). All models were also available in a stretched 'L' version, which had 10 cm of extra legroom for the rear passengers.
BMW 7 series E38 (1995-2001)
The E38 third generation BMW 7 series (1995-2001) had a five-speed automatic or manual transmission. The engine variants in Europe were BMW 725tds, 728i, 730i, 730d, 735i, 740i (4.0 and 4.4 L), 740d and 750i (with a 5.4 L 322 bhp [240 kW] engine, as was used in the Rolls-Royce Silver Seraph).
In the Americas, the models were sold as the 740i, 740iL and 750iL. The 740i and 740iL share the same 4.4 L V8 BMW engine. The 740iL is essentially a long-body 740i (hence the "L" in the model name). The considerably rarer 5.4 L V12-BMW powered 750iL was only available as a long-body; there was no BMW E38 750i in the US lineup. The 750iL was BMW's flagship sedan.
A performance-enhancing sport package was available in the 740i as well; cars with this package are called the 740i Sport. A separate sport package was finally offered in the 740iL and 750iL in 2001, the final year of E38 production.
Features of the E38 7 Series included high-pressure headlight washers, auto-leveling Xenon low-beam headlamps, power moonroof, a six-CD changer with 14 speakers and four subwoofers, onboard navigation and rain-sensing wipers. Other features included an automatic climate control system with full left/right controls and a 3-position memory system for the driver’s seat, safety-belt height, steering wheel and outside mirrors. Front side airbags and a Head Protection System (HPS) were also standard. The car featured an all-leather interior with burl walnut trim. The continuous passive motion "Active" seat technology was introduced in 1998 to improve comfort for the driver and front passenger.
The 5-speed automatic transmission came with Adaptive Transmission Control, Sport and Manual modes for responsive handling.
The base prices in 2001 were US$62,900 for the 740i, US$66,900 for the 740iL and US$92,100 for the 750iL.
740iL and 750iL Protection Line light-armored vehicles were built from 2000-2001, and cost US$99,100 and US$124,400, respectively. These models included body armor, bullet-resistant glass and run-flat tires.
A rare executive V12-powered stretch limousine was also produced, called the BMW L7.
BMW 7 series E65/E66 (2001—present)
The current fourth generation BMW 7 Series is available on two different platforms: the standard-wheelbase E65 (2990 mm, 118 in) and the extended-wheelbase E66 (3130 mm, 123 in).
This car was also the first production BMW to be styled by Chris Bangle. The styling is controversial and has received mixed reviews.
The E65/E66 BMW 7 Series features BMW's iDrive system, consisting of a video screen in the dashboard and a controller mounted on the center console that is used in a similar way to a computer mouse. Using a system of eight menus, most of the car's climate, audio, navigation, suspension and communication settings are controlled via BMW iDrive. However, the system has been criticized by some for being too complex and for distracting the driver from the road.
"Active" Seat continuous passive motion technology is made standard equipment on the 750/760 models and included in the BMW Luxury Seating Package with heated and ventilated seats for driver and front passenger on the 745 models.
The BMW 7 Series was refreshed for 2005 with tweaked front and rear styling and a larger, more powerful V8 BMW engine.
Considerable work went into the rear quarter of the car to reduce the "Bangle Butt" design. The refreshed BMW 7 Series sport a new taillight and reduced height for the trunk lid. The front headlight and the kidney grille was also raised a tad, as well as a new front air dam.
The 4.4 L BMW V8 was replaced by a 4.8 L unit producing 360 hp (269 kW) and 360 ft·lbf (488 N·m). The new model with the enlarged engine is now known as BMW 750i and 750Li (for the long wheel-base model). The 750i and 750Li replace the 745i and 745Li in all world markets. The 745d, powered by a 4.4 L BMW diesel producing 295 hp (220 kW), replaces the 740d. As before, a six-speed automatic transmission with BMW Steptronic is standard on all models.
