BMW 7 Series (E38)
Produced from April 1994 to 2001, the BMW E38 was the third generation of the BMW 7 Series. The flagship represented an attractive evolution in design language of the prior E32 generation. The new 7 was available with straight-six, V8 and V12 petrol and straight-six and V8 diesel engines. In 2001, the E38 was replaced by the E65 7 Series.
The E38 was the first car available with curtain airbags. It was also the first European car to offer satellite navigation and the first BMW to offer an in-built television. The E38 was the first 7 Series to be available with a diesel engine.
Development
In early 1988, development began on the third generation of the 7 Series. From 1988 to 1990 styling work was done initially under design director Claus Luthe, when Boyke Boyer's concept design was chosen and further refined into production form.In February 1991, the final production design for the new 7 Series was approved by the board 36 months ahead of scheduled start of production for February 17, 1994. On April 27, 1993 German design patents were filed featuring a pre-production prototype as a design representation. Patents were later filed on October 27, 1993 in the United States.
Production
Production started on July 23, 1993 on pilot production models and US specification variants on January 13, 1994, with series production commencing in April 1994 for June 1994 domestic German launch with the 730i and 740i. US-specification cars entered production in September 1994, for November 1994 launch. On February 18, 1994, the E38 BMW 7 Series was unveiled for the 1995 model year via a BMW press release. The 750i production began in November 1994, in advance of its January 1995 launch.The last E38 rolled off BMW's assembly line on July 27, 2001 to make way for the replacement E65 7 Series.
Equipment
Safety features include ASC+T traction control, headlight washers and auto-leveling low beam xenon HID headlamps. Side tubular airbags were fitted as standard equipment. "Active Comfort Seats" were introduced in 1998, to improve comfort and reduce fatigue for the driver and front passenger. This system uses two fluid-filled bladders which alternate in height.Other equipment includes Electronic Damper Control, power moonroof, rain-sensing wipers, dual zone climate control, electric drivers seat adjustment and electric steering wheel adjustment.
Double glazed windows were available. Break resistant laminated "security glass" was also available, which is known to delaminate. The delamination occurred with the Protection S357A option only, not with normal S352A dual pane windows. Bullet-resistant glass was used for the Protection model, with even thicker glass used for the Security model.
The Sport Package included a sport steering wheel, sports seats, sports suspension, "shadowline" exterior trim and unique wood trim for the interior. Some sports models also included a shorter differential ratio and higher stall speed for the torque converter. This allowed for a 0–97 km/h acceleration time of 5.9 seconds.
In-car electronics
The E38 was the first European car to be available with satellite navigation, a system called CARIN jointly developed by BMW and Philips.The in-car entertainment are part of an automotive communication system called I-bus.
A "multi-function" steering wheel, with controls for the audio, phone, cruise control and air recirculation, was standard equipment.
Transmissions
A 5-speed ZF 5HP automatic transmission was available on all models.In some markets, a 5-speed manual transmission was available for the 725tds, 728i, 730i, 735i and a 6-speed for the 740i.

Features included electrically adjustable rear seats, rear footrests, fold down rear trays, a fridge, rear television screen, video player and a fax machine.Based on the 750iL with a 12-cylinder engine, the L7 has an electronically limited top speed of. The L7 was only available in the Middle East, Southeast Asia and Europe, and 899 examples were built. The 2000-2001 models had an optional "privacy window" glass partition to separate the driver from the rear passengers.
Protection line
The armoured "Protection Line" vehicles were built from 2000–2001 and were based on the 740iL and 750iL models. Security features include body armor, bullet-resistant glass and run-flat tyres. An intercom system is provided to communicate with people outside the vehicle while the windows and doors are shut.Security line
A High-Security version with protection up to B6/7 was also available in Europe, known internally as the 750iL S. The additional security measures brought an additional weight of compared to the normal 750iLFeatures include explosive cord around the windshield allowing removal of the windshield facilitating escape through it in case of a rollover crash and Hydraulically actuated windows.
A gas sensor can detect irritants like CS gas and respond by turning the blower motor off closing the fresh air flaps and all windows. A fire suppression system is triggered by either a button or the detection of extreme temperatures in the engine bay or the vicinity of the fuel tank.
A breathing air system is also available which delivers air from a cylinder in the trunk,
up to three firearms cases designed to fit a Heckler & Koch MP5K were also optionally available as well as spherical gunports in the doors.
Hydrogen 750hL
On May 11, 2000, BMW presented a fleet of fifteen 750hL's in Berlin.Its twelve-cylinder hydrogen combustion engine can be operated on both hydrogen and petrol. In operation on hydrogen, it delivers, accelerating from 0 to 100 km/h in 9.6 seconds and slowing the car to attain a top speed of.
The production of the hydrogen engine was integrated into the regular engine production at the Dingolfing plant. It differs from the conventional petrol engine essentially only in regards to the intake tract with additional injection valves for hydrogen. The hydrogen is stored cryogenically at a temperature of minus 253 degrees Celsius in a double-walled steel tank behind the rear seat back. The hydrogen tank holds 140 litres and allows an additional range of. In addition, the 750hL has a fuel cell rated at at 42 volts. This is not used as a drive unit, but as an auxiliary power unit for power supply to the electrical system.
During the Expo 2000 in Hanover the vehicles were used as shuttles. From February to November 2001 the vehicles were part of the "CleanEnergy WorldTour 2001" in the cities of Dubai, Brussels, Milan, Tokyo, Los Angeles and Berlin. By November 2001 the 750hL had achieved a mileage of over 150,000 km. On the Nürburgring the 750hL recorded a time of 9 minutes and 53 seconds while powered by hydrogen.
