The BMW 7 Series gets its latest and likely most fuel-efficient version in the 740Ld xDrive, a first-ever U.S. diesel version of the automaker's flagship sedan. Offered in one configuration — long wheelbase with all-wheel drive — the 740Ld xDrive will join more than a dozen other versions of the 7 Series when it goes on sale this spring. The automaker will show the diesel 7 Series at February's 2014 Chicago Auto Show.
BMW says the 740Ld xDrive starts at $83,425, including a $925 destination charge. That's $1,500 more than the gasoline-powered 740Li xDrive and just $30 more than the sole diesel version of Audi's all-wheel-drive flagship sedan, the A8 L 3.0 TDI ($83,395, including destination). If you pick the Audi, you can blow the difference on one of these. Standard and optional equipment lists are pending, but we expect that, like other versions of the 7 Series, optional equipment will send the 740Ld well into the six-figure range.
