The facelifted BMW 7 Series goes on sale this July and along with mild exterior upgrades, it also brings to market new exterior colors, engines and features.

BMW introduces a new model in the 7 Series lineup: 750d and 750Ld. The high-end diesels are powered by the new tri-turbo 3.0 liter engine which is based on the popular 3.0 liter inline-six (N57D30), but with an extra turbocharger. The innovative powerplant produces 381 horsepower and 740 Nm (546 lb-ft) of torque. With 93.6 kW/127.3 hp per liter of displacement, the N57 sets a new benchmark standard for diesel engines.

Another diesel model to receive an upgrade is the entry level 730d. The updated N57D30001 unit now produces 254 horsepower and 560 Nm of torque (413 lb-ft).

The two diesels, in both rear-wheel-drive and xDrive, are available only to European customers.

Both the F01 and F02 7ers will offer their customers an extensive range of exterior colors, with the latest additions being Havana, Glacier Silver and Midnight Blue.

Starting as of July 2012, the next generation iDrive navigation system will be available on the 7 Series. The new system offers faster processing and an enhanced design over the current iDrive system. A new multi-touch iDrive knob, similar to the Audi system, will allow the driver and passenger to easily enter numbers and characters through gestures without looking at the system. The new iDrive also includes software upgrades: Streamlined radio/menu and navigation structure, Advanced Real-Time Traffic Information, Weather info and more Google Search features.

Moving outside the car, the F01 and F02 7er LCI models will feature full LED headlights that were redesigned to look sleeker and are smaller in size. A new eyebrow now hosts the turn signal indicator. All 7 Series LCI models will get the signal indicator integrated into the side mirrors.

We anticipate a web debut of the 2013 BMW 7 Series in the upcoming weeks.
