BMW's workhorse 3.0-liter, turbocharged 6-cylinder engine makes 300 horsepower in those models with "35i" designations, while the xDrive50i gets an upgraded and more powerful 445-horsepower, twin-turbocharged V-8 engine for 2015.
A variety of wheel choices help tailor the new X6 to specific tastes, and buyers can upgrade the HID headlights to LED illumination complete with automatic high-beam operation.
Inside, BMW's layered design approach is rendered in a variety of materials and colors, and Interior Design packages add greater levels of luxury.
Leather seats are standard, along with BMW's iDrive infotainment system and a new Dynamic Digital Instrument Cluster with configurable black-panel technology. Seating is designed to supply comfort for four people, though a fifth passenger can squeeze in when necessary.
The 40/20/40 split-folding rear seat expands cargo capacity from 20.5 cu. ft. to 53.9 cu. ft., and a power tailgate with a soft-close function is standard. Optionally, the tailgate can power open and shut by itself after the person with the Comfort Access key fob waves his or her foot under the rear bumper.
Every 2015 X6 is equipped with BMW Assist and BMW Apps services, supplying a number of safety and infotainment functions. Upgrades include a navigation system with touchpad entry technology, a premium surround-sound audio system, rear-seat entertainment system, head-up display, and a park-assist system.
Among the X6 model's option packages are the Dynamic Handling package, Cold Weather package, Driver Assistance package, and the Driver Assistance Plus package.
In Eco Pro mode, the X6 attempts to maximize fuel economy through powertrain response, a coasting function, Proactive Driving Assistant feature, and more efficient navigation route mapping. Additionally, the new X6 is equipped with automatic start/stop technology and a regenerative braking system.
