The BMW E53 is the first-generation BMW X5 mid-sized luxury crossover SUV. It was produced from 1999-2006 and was replaced by the BMW E70. The E53 was developed at a time when BMW still owned Land Rover and as such shares many components and designs with both the Land Rover Range Rover L322 model and the BMW E39 5 Series. The entire in-car entertainment system are shared with other BMWs and L322.
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 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 was frozen, 35 months prior to production. Design patents were filed on 10 June 1998 and 9 December 1998, being registered in the U.S. on 18 January 2000. The takeover of Rover in 1994 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 instead of an SUV. Even though the X5 was an all-wheel drive vehicle, BMW chose from the start to route 62% of the engine's torque to the rear wheels, making it feel as close as possible to the company's rear-wheel drive sedans.
A sport model, badged 4.6is was released in 2001. The 4.6is, equipped with the M62TUB46 V8 engine, made. The 4.6is was available in 4 colors. 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 had a 4.8L N62 engine producing.
2003 Facelift
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. 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. 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 and DSC to brake wheels 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. Also from April onwards, a new X5 4.8is was offered, producing. Sales began in September 2003. Several new extras were added to the 2004 X5 such as:
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, and was also later used in the 2005 750i/Li. It also included a slightly modified bodykit, 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.
