The next-gen G11 BMW 7 Series – due in 2016 – could come with an ‘extended wheelbase’ version as a response to the upcoming Mercedes-Benz S-Class Extended Wheelbase, according to BMWBlog.

The current F01/F02 7 Series LCI (pictured) is available in short- and long-wheelbase configurations, but the new W222 S-Class sedan will spawn short-, long-, extended-wheelbase and six-seater Pullman versions.

While the S-Class Pullman will be in a class of its own, the introduction of an extra-long 7er could divert the┬áS-Class Extended Wheelbase’s crosshairs away from BMW’s Rolls-Royce Ghost. Unsurprisingly, the main markets are likely to be China and the Middle East.

Thanks to more extensive use of carbon fibre, plus a roof, bonnet and boot lid that are likely to be made out of CFRP (carbon fibre reinforced plastic), the G11/G12 BMW 7 Series is set to be lighter than the current car. The base 740i is said to weigh “dramatically” less than 1,900 kg, BMWBlog reports.
