BMW X5 xDrive 35i receives a brand new inline-6 gasoline engine, internally dubbed "N55." The new engine features the same 3.0-liter displacement and 300 horsepower output of its predecessor (the "N54"), but features a single twin-scroll turbocharger in place of the previous twin, low-mass turbocharger units. Furthermore, the new inline-6 of the BMW X5 xDrive35i is the first BMW inline-6 to combine BMW's revolutionary Valvetronic throttle-less intake technology, High Precision direct fuel injection, and turbocharging. The result of combining this new inline-6 with the new 8-speed automatic is an BMW X5 with incredibly spontaneous responsiveness, exceptional power, and remarkable efficiency. The new BMW X5 xDrive35i will perform the 0-60mph sprint in 6.4 seconds, coincidentally on the same pace as the outgoing V-8 powered BMW X5 xDrive48i.

For the 2011 model year, BMW has made the X5 xDrive35i available in two additional trim levels: "Premium" and "Sports Activity."

The essential BMW X5 xDrive35i has an MSRP of $46,675 including Destination & Handling, and includes a popular profile of standard equipment often specified by BMW X5 customers, including BMW's Xenon Adaptive headlights, Rain Sensor with automatic headlight control, HD Radio, automatic climate control, foglights, 18" light alloy wheels, cruise control, and anti-theft alarm system.
