The E32 was introduced in 1987, with the 730i and 735i featuring 3.0 L and 3.5 L straight-6 engines respectively, and a new, 5.0 L, 300horsepower (220kW) V12 engine for the 750i. In 1992, 3.0 L and 4.0 L V8 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. See BMW E32 article for more information.

The E38 generation (1995-2001) had a five-speed automatic. The engine variants in Europe were 725tds, 728i, 730i, 730d, 735i, 740i (4.0 and 4.4 L), 740d and 750i (with a 5.4L V12 322bhp (240kW; 326PS) 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 shared the same 4.0L V8 engine in model year 1995, but the next year the V8 grew to 4.4L while stated power stayed at 282hp, though torque grew from 295lb-ft to 310lb-ft. Then again coinciding with the 1999 facelift, the V8's power again stayed the same but now torque grew further to 324lb-ft, due to new variable valve timing. The 740iL is essentially a long-wheelbase 740i (hence the "L" in the model name). The considerably rarer 5.4L V12-powered 750iL was only available as a long-body; there was no E38 750i in the US lineup. The 750iL was BMW's flagship sedan (not counting the Rolls-Royce models, owned by BMW at the time).

The current 7 Series is available on four different platforms: the standard-wheelbase E65 (2990mm, 118in), the extended-wheelbase E66 (3130mm, 123in), the High Security version E67 and the hydrogen powered version E68.
The E65/E66/E67/E68 7 Series features BMW's first of a kind 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 iDrive. However, the system has been criticized by many automotive writers as being too complex and not intuitive enough.
