The BMW E53 is the first generation BMW X5mid-sizeluxurycrossover SUV. The vehicle was the first SUV ever produced by BMW. It was produced between 1999 and 2006[1] and was replaced by the E70 X5.
The E53 X5 was developed just after the acquisition of Land Rover by BMW. As such, the vehicle shares many components and designs with both the Range Rover L322 model (specifically the hill descent system and off-road engine management system) and the BMW E39 5 Series (specifically engines and electronic systems). The entire in-car entertainment system (radio function, navigation system, television and telecommunications systems) are shared with other BMWs and L322. As a result, the earlier X5 models can be upgraded with newer BMW technologies (e.g. Bluetooth phone connectivity).[2]
History

The history of the X5 begins in 1994, when ideas began on a BMW sports utility vehicle after the acquisition of Land Rover. Eduard Walek was named project leader and chief engineer of the E53. Chris Chapman joined BMW Group's Designworks in California later and began working with Chris Bangle in Munich on two full-scale clay models of the E53 for two months. By 1996, design work was approved and the design basis for the X5 (E53) was frozen, 35 months prior to production. Design patents were filed on 10 June 1998[3] and 9 December 1998, being registered in the U.S. on 18 January 2000.[4][5][6][7]
The takeover of Rover in 1994 was proved to be very beneficial for BMW in the development of the X5. BMW engineers were able to look at and use Range Rover technology and parts in the development of the X5 - one such example would be hill-descent control. In many respects, the design of the X5 was influenced by its British counterpart; for example, the X5 got the two-piece tailgate straight from the Range Rover. Many parts and electronics were also taken directly from the E39 5 Series parts bin to save costs.
In contrast to the Range Rover models, the X5 was designed as a sporting road car: its off-road capabilities are significantly less than those of Land Rover. BMW reportedly worked hard to ensure it was referred to as an SAV (Sports Activity Vehicle) instead of an SUV (sport utility vehicle).
Even though the X5 was an all-wheel drive vehicle, BMW chose from the start to route 62 percent of the engine's torque to the rear wheels, making it feel as close as possible to the company's rear-wheel drive sedans.
The interior design of the E53 X5 was shared with the BMW 5 Series (E39), featuring a similar dashboard layout. The BMW Business Cassette head unit was standard equipment on all E53 X5 models, and included controls for a separately-mounted CD changer unit. The BMW Business CD head unit was optional, and later became standard equipment on newer E53 X5 models. The BMW Business CD head unit also included controls for an accessory CD changer unit. A GPSnavigation system radio was also available, and replaced the standard CD player with a cassette player located behind the unit's retractable LCD display screen, but included controls for an accessory CD changer unit. A "Hi-Fi" premium sound system was standard equipment on all E53 X5 models, while an upgraded system with a Digital Sound Processing (DSP) was optional, regardless of head unit option. The BMW Assisttelematics system was an option on the E53 X5, and included an "SOS" button in the overhead console.
A sport model, badged 4.6is was released in 2001. The 4.6is, equipped with the M62B46 V8 engine, made 255 kW (342 hp). The 4.6is was available in 4 colors (black, imola red, estoril blue, and titanium silver). It featured 20 inch wheels that were fitted over larger brakes than the stock X5. It also had additional rear fender flares along with different front and rear bumpers. In 2004, the 4.6is was replaced by a 4.8is model which was not the M62B48 4.8L V8, which Alpina developed for its Alpina B10 V8S
and the Alpina Roadster V8, but rather an entirely new engine called the N62 engine producing 265 kW (355 hp).
2003 facelift
Facelift BMW X5 3.0d (Australia)
In 2000, development on mid-cycle updates began scheduled for 2003. By late 2001, a radical design update was chosen favoring the new brand design theme. In 2002, following discontent towards the 2001 E65 design, a more conservative appearance was instead chosen and frozen for 2003 production.[15]
In July 2003, the facelifted X5 was presented for the 2004 model year at the IAA 2003 in September, with new headlights, a few new exterior colors, a new four-wheel drive system and upgraded engines. Production started at Spartanburg on 26 September.[13][16] The grilles were enlarged, as well as their actual slats being modified in a 'flame surfaced' style. In keeping with the E39 facelift of 2001, the 2004 X5's headlights got corona rings around all four headlamp projectors. The tail-lights also received a facelift similar to the BMW E39, and the exterior glass went from a "dotted" pattern to a cleaner "line" pattern. BMW invented a new four-wheel drive system dubbed xDrive shared both in the X5 and X3 in 2004. Instead of using the previous X5 system which consisted of power being split 62-38 (rear wheels-front wheels) and DSC to brake wheels without losing traction, xDrive could vary power to the front or rear axles in milliseconds, transferring up to 100% of engine power to either axle, thus allowing the vehicle to regain traction quickly.
The X5 got the new 4.4i engine which debuted in the 2002 7 Series; power output rose from 216–235 kW (290–315 hp). Also from April onwards, a new X5 4.8is was offered (see below), producing 265 kW (355 hp). Sales began in September 2003.
Several new extras were added to the 2004 X5 such as:
Soft-boot close feature (the top part of the trunk pulls itself closed)
Adaptive Headlights (available only with xenon HID headlamps; these swivel with the direction of travel of the car. Bi-Xenon headlights for both low and high beam replaced the low beam HID headlights)
Originally announced in the end of 2003 along with the rest of the X5 facelift, the X5 4.8is first started shipping in April 2004. It had a new larger 4.8 L engine (which replaced the 4.6 L engine), and was also later used in the 2005 750i/Li. It also included a slightly modified bodykit (parts of the bottom bumper became painted the body color), 20" wheels, and along with the 4.6is, were the only X5's ever to have a large chrome-tipped exhaust which hid the quad pipes.
An intercom to speak with people outside the vehicle.
An assault alarm, which when activated, locks all doors and emits both visual and audio alert signals.
Run-flat tires allowing one to continue driving with flat tires at up to 80 km/h (50 mph) for approximately 50 km (31 mi).[20]
Chinese copy controversy
In June 2008, the Regional Court of Munich ruled that the Chinese SUV model, "Shuang-huan SCEO" is a copy of the BMW X5, prohibited the defendant importer of these vehicles in the "trade in Germany" offer and ordered the destruction of all "vehicles with a certain look" at which the defendant's possession or ownership (Az.: 4HK O 16807/07).[21]
