The BMW F25 is the 2nd generation model of the BMW Sports Activity Series X3, on sale since 2010. The 2011 X3 was unveiled on July 14, 2010. The new car is larger than its E83 predecessor and is assembled in BMW's Spartanburg Plant, in Greer, South Carolina in a new manufacturing facility alongside the existing X5 and X6 assembly hall.

Power for the North American version of the X3 comes from BMWs' N52 3.0L Direct Injection I6 engine for the xDrive28i shared with the new F10 528i and BMWs' new N55 3.0L TwinPower Turbo (single turbo twin scroll) Direct Injection I6 engine for the xDrive35i as seen in its larger facelifted X5 sibling.

(For the 28i the I6 N52 engine is to be replaced with the four-cylinder, TwinPower Turbo N20 engine all across the BMW lineup for the 2012 and 2013 model year; implementation date in the X3 is to be confirmed.)

Both engines are mated to either a 6-speed manual or 8-speed automatic transmission. The U.S. market gets the 3.0 inline-6 and automatic transmission combination; no four-cylinder diesel engine version will be sold. Outside the USA & Canada, the X3 is offered with three diesel engines: the 20d (2.0-liter I4 diesel), the 30d (3.0-liter I6 diesel), and BMW's new 35d (3.0-liter TwinPower Turbo I6 diesel). In some European countries, the 35i and 28i petrol engines are not offered on the F25.

The BMW X3 is a compact crossover SUV marketed by the German automaker BMW since 2003. Based on the BMW 3 Series platform, and now in its second generation, BMW designed the X3 in conjunction with Magna Steyr of Graz, Austria—who manufactured all X3s under contract to BMW for the first generation. Production of the second generation vehicle has transferred to BMW's Spartanburg plant in South Carolina, United States.

Following the X5, the X3 was the second vehicle marketed by BMW as a Sports Activity Vehicle (SAV).

BMW presented the precursor to the X3 as a concept vehicle unveiled at the Detroit Auto Show in 2003. Dubbed the xActivity, BMW previewed a SAV based on the 3 Series platform, without windows and a vestigial roof.

As BMW used parts from the E39 5 Series in making the X5, likewise BMW engineers employed 3 Series parts with the X3, for example, the rear suspension from the E46 330xi.

When the BMW X3 premiered in late 2003, BMW announced that it would employ a new four-wheel drive system to power it and the X5, a system marketed as xDrive that would intervene transparently to the driver before the driver was aware of instability.

Armin van Buuren (Dutch pronunciation: [ˈɑr.mɪn vɑn ˈby.rə(n)]), OON (born 25 December 1976 in Leiden, Netherlands) is a Dutch trance producer and DJ. Between 2007 and 2010, he was voted number one in DJ Magazine's annual top 100 list of the most popular DJs. In the 2011 list, he ranked in second place. Since 2001, Van Buuren has hosted a weekly radio show called A State of Trance, which claims to have around 15 million weekly listeners in 26 countries, which would make it one of the most listened-to radio shows in the world. His 2008 studio album, Imagine, entered the Dutch album chart at #1, a first for a dance music artist in Dutch music history.

Armin van Buuren was born in Leiden, Netherlands on 25 December 1976, but grew up in Koudekerk aan den Rijn. Van Buuren started making music when he was 14.^{[citation needed]} He was inspired by French electronic music composer, Jean Michel Jarre, and wished to become a great electronic music composer like Jarre.^{[citation needed]}

He finished high school at the Stedelijk Gymnasium Leiden in 1995, and left for college to study law at Leiden University. While studying law, Van Buuren's interest for making music blossomed, and he began working as a DJ in a local club called Nexus. As his musical career began to take off, he put his law degree on hold, although he did return to finish law school in 2003.
