A report that appeared on Spanish site Motores suggests that the next BMW 7-Series flagship will use the Rolls Royce Ghost and Wraith’s newer V12 engine for the top of the range model (probably still called the 760i).

The 6.6-liter twin-turbo unit codenamed N74B66 is an offspring of BMW‘s NB60 6.0-liter V12 found in today’s 760i/760Li.

The V12 is said to produce around 600 hp in the BMW, but curiously, the source report suggests it won’t be made available with xDrive all-wheel drive.

At the other end of the engines range, there will be a 730i mode that will get its power from a turbocharged 2.0-liter four-pot with 250-ish hp. Additionally, there will apparently be more than one hybrid version to choose from too – these could be dubbed 730e and 740e.

We’ve already seen the new 7-Series’ interior and its new touchscreen iDrive infotainment display. It looks like fairly typical BMW fare, but the inside was never the issue with the big BMW – the somewhat grotesque exterior styling (especially visible on the pre-facelift current gen car) will be gone, and we hope to have the first really classy looking 7 since the iconic looking E32 of the mid 1980s (the E38 looks nice too, but it’s a tad boring to behold).
