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.

Junkyard Gem: 1965 Jaguar S-Type 3.8

The first Jaguar XJs appeared on American roads in late 1968, and decades of production made it the iconic Jaguar sedan most familiar to us today. Before the XJ, however, there was the Mark 2, and that powerful and stylish midsize saloon sold fairly well here during the 1960s. The S-Type (yes, the Leaper-badged Lincoln LS sibling built by Ford around the turn of the century took its name from this car) was an upgraded version of the original Mark 2, sold here for the 1964 through 1968 model years. Here's a rough but recognizable '65 S-Type 3.8, found in a Denver-area wrecking yard recently. The feature that set the S-Type apart from the ordinary Mk2 was this independent rear suspension, based on the one used in the bigger and costlier Jaguar Mark X. The base Mk2 and its old-timey solid rear axle remained available in 1965, with a sticker price of $5,419 (about $51,460 in 2022 dollars), while the S-Type cost $5,933 (around $56,340 now). Yes, those inboard disc brakes were just as much a nightmare to work on as you'd think, but they reduced unsprung weight and improved the handling and ride. This car was about the same size as a typical Detroit midsize sedan of the day, but far more expensive and much more prestigious. GM's swankiest S-Type-sized offering, the Buick Skylark, cost a mere $2,552 ($24,235 today) and had a notable lack of real wood inside. Actually, that Skylark with the optional 300-cubic-inch (5.0-liter) "Wildcat 355" V8 would have been a lot quicker than the S-Type, at least in a straight line, and your friendly Buick dealer probably could have arranged to have the hot-rod 401 (and its 325 horses) out of the Gran Sport coupe stuffed into a new Skylark sedan. The S-Type of 1965 got this sophisticated DOHC straight-six of 3.8 liters' displacement, rated at 220 horsepower. As you'd expect, someone grabbed the pair of SU sidedraft carburettors before I got here, perhaps before the car even arrived at this place. The 4.2-liter version of this engine used in the Mark X got three carbs. I suspect that this car was bought by a Denver-area Jaguar enthusiast for parts, decades back, and then was used for outdoor storage of components for future projects.  These cars are worth decent money in good condition, but this one would need the application of tens of thousands of dollars to be worth … tens of thousands of dollars. As someone who daily-drove an MGB for a few years, the sight of all this Lucas electrical hardware makes me sweat a little.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.
