BMW X5 E53

BMW introduced it’s E53 series X5 to the market place, which saw the first line up of the new SUV roll off the production lines in late 1999 and into car dealership showrooms in early 2000. It was classed as an American: Mid-sized SUV and European: J-segment 5-door vehicle with a front engine, four wheel drive layout and was manufactured until September 2006. The BMW X5 E53’s were manufactured in Greer, South Carolina at the Spartanburg BMW plant and in Mexico at the de México Toluca plant. Since 2009 certain vehicle assembly operations were also performed in Russia by Avtotor.

The BMW X5 is also referred to as a midsize luxury CUV or ‘Crossover Utility Vehicle’ that was produced by the automaker BMW. The first generation of the X5, with the chassis code E53, made its debut in September 1999 and was BMW's first SUV or ‘Sport Utility Vehicle’, also known as "4X4" in the United Kingdom, which featured an all-wheel drive or 4x4 and was made available in manual or automatic transmission.

The X5 Sport Activity Vehicle was branded as an SUV instead of a 4X4 vehicle to emphasize its road characteristics and road comfort and ability, despite its size. The X5 shifted from light truck based body-on-frame SUVs to crossovers underpinned by unibody car platforms while the Mercedes-Benz M-Class had beaten the X5 to the market by a full year.

The E53 was fitted with a 4.4 litre V8 all aluminium engine with a four valve per cylinder and a double VANOS and DOHC cylinder head configuration and is also fitted with Sequential fuel injection. The variable valve timing was fitted to the later "M62TU" engine. The conrods are forged sintered and fracture slit to ensure a better fit, preventing distortion of the big end of the connecting rod.

Compared with its M60 predecessor, the M62 features an Alusil cylinder block and liners in market where high sulfur fuel was sold and a single row timing chain and tensioner rail setup for better performance. BMW together with

Kolbenschmidt enhanced the older type block prevalent in the pre 1997 engines that featured cylinder block liners that were electroplated with Nikasil, a hard chrome like plating.
