Jaguar Land Rover to drop supercharged V8 for turbocharged BMW power

There are few things that sound as good as Jaguar's 5.0 liter supercharged V8. As great as it is when the supercharger whines or the exhaust cracks and pops on throttle lift-off as the air pressure equalizes, the basic design dates back to the '90s. Plainly, the engine isn't as efficient as it needs to be, but designing a new V8 from the ground up is an expensive proposition. Instead, Automobile reports that Jaguar Land Rover is set to use a twin-turbocharged V8s supplied by BMW. 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.

Hey wait, not everyone hates the diesel engine in our 2017 Jaguar XE

My friend Joel doesn't seem to care for the turbocharged 2.0-liter diesel engine in our long-term 2017 Jaguar XE 20d. That's fine. He's entitled to his opinion. But he does not speak for the entire Autoblog staff. I, for one, am a big fan of this oil burner. I said so months ago after I returned from a 2,000-mile road trip. The intervening months have done nothing to sway my opinion. It's smooth, efficient, and all the engine you need in a non-performance application. It may not have the raw power or full range torque of the XE's gasoline engines, but it's a fine fit in this car. Not everyone who buys a sports sedan like the XE or BMW 3 Series does so because they want a sharp canyon carver. Some just want a handsome car that will get them from point A to B in relative comfort. The Jaguar XE diesel does just that, and it does so while achieving some pretty astounding fuel economy numbers. We met the 30 mpg city rating and eclipsed the 40 mpg highway rating with ease. It's not like the XE diesel is slow. Sure, a 0-60 mph time of 7.5 seconds isn't blistering, but it's far from what anyone should consider slow or lethargic. That time is right on par with the BMW 328d. Sure, it runs out of breath at peak revs, but so does every other diesel. If you care about wringing it out, buy a gas version. By Joel's own admission, the engine's 180 horsepower and 318 pound-feet of torque are available when needed for highway passing or city driving. That's all most people really need. So what if it falls on its face at high revs. I will concede that this isn't the most refined diesel on the market. At idle, it shimmies like an unbalanced washing machine. Jaguar has tuned a lot of that out, but it isn't nearly as calm as the competition (though it's miles better than diesels of old). It revs quickly for a diesel, but the exhaust note is one to forget. The engine sounds like a muffled foghorn mixed with a jar of nails. Not good. Once you get moving, it settles down. Highway cruising is a breeze. You forget you have a compression ignition engine under the hood. Even around town, turn the radio on and you'll be fine. Joel is right about the ride and handling totally outclassing the diesel engine. The car is comfortable on highways and city streets but sharpens up on a curvy backroad. The steering and suspension communicate to the driver what the car is doing at all times. The brakes inspire confidence with a firm pedal and sharp bite.
