The rumors have come from several different places throughout the year and they all point to the same thing: we can expect a BMW M760i in 2016 to sit at the top of the 7 Series range. One of the latest scraps of evidence comes from a forum member at Bimmerpost last month who wrote that an M760i would arrive for model year 2017, and it would be the the only regular-wheelbase version with a 12-cylinder engine even if a 760i model joins the lineup. The long-wheelbase 760Li, however, would also get a 12-cylinder motor.

This week, BMW Blog published what it says is an accidentally leaked image from the German BMW configurator (pictured) that shows an M760i badge. The actual model doesn't appear, but the configurator places the badge over the 7 Series model you choose to configure. This will be the second 7 series to wear an M badge, and whenever we see it, we're told it will get the M Sport Package and Ferric Grey accents. The first M-badged 7 Series was a limited edition for the Middle East sold two years ago.

Both the M760Li and 760Li are tipped to use the 6.6-liter V12 found in the Rolls-Royce Ghost and Wraith - that engine being an evolution of the V12 that powered the last-generation 760Li - but their outputs will vary. The long-wheelbase 7 is expected to get 600 horsepower. The M760i is said to get 624 hp, matching the output of the Wraith, and maybe some handling refinements to make it a proper competitor for counterparts from Mercedes-AMG, Audi, and Jaguar. On top of all that there will still be an Alpina B7, rumored to have 600 horses of its own. Introduction of the range could take place at the 2016 Geneva Motor Show.
