Scalable architecture is all the rage as automakers streamline designs in order to save costs. For example, Jaguar's current supercharged V6 is quite literally a V8 with two holes missing. They didn't even change the length of the block. It seems both of those designs are on their way out, with the V6 being replaced by a inline-six closely related to the company's inline four. It seems that rather than designing an new and expensive V8 for their top of the line models JLR, is sourcing from BMW.
From 1994 to 2000, BMW owned Land Rover. A few models, including the Land Rover Range Rover, used BMW engines then and in the initial years of Ford's JLR stewardship. It seems things have now come full circle. BMW currently makes a twin-turbo 4.4 liter V8 that produces anywhere from 440 to 600 horsepower, depending on the application. Automobile says that a new 4.0 liter V8 is in the works and that it will most likely be the engine that JLR uses. Expect it to be more powerful, more fuel efficient, and lighter than what both BMW and JLR currently offer.
This seems like a win for both companies. BMW gets to offset the cost of a new motor while JLR, a smaller company, doesn't have to invest in a whole new architecture. As automakers search for ways to cut costs, expect collaborations like this to continue. Infiniti and Mercedes-Benz both share a four-cylinder engine. Ford and GM have worked together to design a shared 10-speed automatic. While we may lament the loss of that wonderful Jaguar Land Rover engine, we can still be happy that they haven't abandoned the V8.
