According to a leak concerning the latest plethora of patent applications from Alpina we can conclude the high-performance brand is looking to bring to the market a roster of hardcore diesel engines for the top three BMW models.
Alpina today has a few diesels up its sleeve: the D3, XD3, D4, and D5 which can be had in the BMW 3 Series, X3, 4 Series, and 5 Series models. The latest rumor flying off the mill now states the company is looking to expand its diesel offering to the flagship series – even taking into account the yet unreleased X7 top of the range sport utility vehicle. Alpina has apparently used a German company dealing with property law to register the trademarks for the D6, D6S, D7, D7S and XD7. The D6 and D7 would most likely be used inside the strong 6 Series and 7 Series diesels which now make use of the biturbo 3.0-liter B57 unit. The D6S and D7S will of course bring even more oomph to the table, but it’s anyone’s guess if the basis will be the same engine used in the regular D6 and D7 or it’s an entirely different, new animal.
BMW has recently outed a new dinosaur – quad-turbodiesel 3.0-liter, six-cylinder in the 7 Series and the power levels are absolute: 394 horsepower (294 kilowatts) and 560 pound-feet (760 Newton meters) of torque. Of course this being an entirely new engine more tweaks can be delivered and Alpina may have the idea of working on it. The XD7 moniker is Alpina planning long ahead – since the BMW X7 itself is not expected on the market until at least 2018.
