Offer is part of new options available for X5 and X6 models as of the spring. New 20-inch alloy wheels also part of the expanded list.

BMW is offering a new set of options for the X5 and X6 models, including a conversion to a 5-seater for the X6 SUV coupe.

By removing the center console on the four-seat X6, an extra rear seat is added large enough to comfortably fit an adult, as BMW demonstrates in the photos published here.

The extra seat option is available for all X6 variants, including the X6 M, except for the X6 ActiveHybrid.

Also new for the X5 and X6 models are 20-inch alloy wheels in a Y-spoke design and a black gloss finish fitted with 275/40R20 tires at the front and 315/35R20s for the rear.

BMW will also be fitting Comfort Access to the X5 and X6 starting in the spring, a feature which provides lighting for the exterior door handles as part of the car key access system.

The brand is also promising shift paddles on the steering wheel for the future X5 and X6 and extending the services of BMW ConnectDrive for the X5 and X6 range to include BMW Apps - a feature which allows connectivity via an iPhone to Apple's iTunes, Facebook and Twitter as well as accessing web radio from inside the car.
