2017 Jaguar XE: We'll miss our long-termer, but not its diesel engine

This may be automotive journalist blasphemy, but diesels aren't always a good thing. And I don't mean that from an emissions standpoint. Sometimes the diesel in question isn't a good engine, and/or is a bad fit for the cars to which they're fitted. Our long-term Jaguar XE diesel is a textbook case of both issues. The first issue becomes apparent from the moment the 2.0-liter turbodiesel four-cylinder fires up with all the clattering, tapping and ticking that can only come from a compression-ignition engine. It's far from the shaking and knocking of full-size diesel trucks of a few decades ago, but it definitely feels a generation or two behind other diesel cars. For instance, we had a diesel Chevy Cruze in the office, which was quieter and smoother than the Jaguar despite a base price roughly $10,000 less. It becomes a bit smoother and less raucous as revs increase, but the volume remains rather high, making it sound as though the engine is struggling more than it is. Though, to Jaguar's credit, the company has managed to keep virtually all engine vibrations from entering the cabin. Now, the diesel engine's voice would be less problematic if it provided some engaging performance, but, outside of the high fuel-economy numbers, there's hardly any to be found. This may seem surprising considering the Jaguar's 318 pound-feet of torque, but that torque figure lasts only briefly from 1,750 rpm to 2,500 rpm. After that, the torque rapidly falls off, and you don't see the Jag's meager 180 horsepower peak until 4,000 rpm -- not far off of the engine's roughly 5,000-rpm redline. As a result, the XE has adequate passing power and around-town shunt, but anytime you want to play with more revs, it faceplants. But at least it does nail, and even exceed, its 40-mpg highway fuel economy rating without trying. The faults of this diesel engine are then exacerbated by the fact that it's in such a smooth and fun car as the XE. It positively glides across rough city streets and highways, keeping the chassis steady and its passengers soothed. Coupled with a quiet cabin, the XE is a peaceful place to be. At least it would be if the diesel didn't rudely interrupt every time the throttle pedal is pressed. Through some sort of black magic, the XE handles about as well as it rides. The incredibly sensitive and accurate steering is superb. It feels like adjustment knobs on a high-end stereo -- weighted perfectly and fine enough to get it right where you want it.

Lightweight E-Type to show historic side of Jaguar Special Operations in Monterey

Jaguar has made a lot of great vehicles over the years, but as far as historians are concerned, it still very much lives in the shadow of the original E-Type, small as it was. In its image, Jaguar has made two generations of XK and the new F-Type, but what we have here is the most faithful continuation of the E-Type heritage yet.
Alongside the Range Rover Sport SVR and the F-Type Project 7 (making its US debut), Jaguar Land Rover and its new Special Operations division will roll into Pebble Beach this year with the continuation Lightweight E-Type. Of the 72,500 E-Types which Jaguar built between 1961 and 1975, only a dozen were Lightweight versions, and they remain the most coveted E-Types of all. It originally planned on building 18 examples, though, and five decades later, it's now committed to completing that original production run in faithful detail.
The Lightweight E-Type was based on the standard roadster and was homologated as such, just with some key upgrades to make it lighter and faster. The biggest change, of course, was the lightweight aluminum bodywork that cut 205 pounds off the curb weight. To replicate it, Jaguar took the last example (the only one made in 1964 after the original eleven were made in '63), scanned half its body surface, mirrored it to ensure symmetry and set about reproducing it with the same standard of materials available in the Sixties (and resisting the urge to go with more modern grades of aluminum). 75 percent of the 230 components are made in-house, with the largest stampings outsourced and built on machinery built to Jaguar's specifications off-site.

Jaguar envisions future without V8 engines

With tighter emissions and fuel economy regulations looming, Jaguar may have to do more than make a small, fuel-efficient hatchback to lower its model range's consumption figures - it also might give up its venerable V8 power, Drive reports. But not anytime soon, says Steven de Ploey, Jaguar's product and marketing director, who recognizes that the V8 can be replaced only by something that offers the same, or better, performance. But he has a word of caution: "We are not wedded to V8s."
In the meantime, de Ploey says there are other ways to reduce emissions. One of the first steps Jaguar could take is to shift away from the use of superchargers, which aren't as good as turbochargers at maintaining efficiency and making power. But he adds that supercharging still is "at the heart of Jaguar's performance proposition," and that the company has addressed the current downsizing trend by "replacing our naturally aspirated V8 with a 3.0-liter supercharged V6."
Consider one of de Ploey's comments on the cancelled C-X75 supercar (pictured) for some clue about Jaguar's future: "Some of the stuff we have already exploited to the extreme in the C-X75 is the kind of thinking for us and is an essential test bed to see how we could evolve from today to something that is sustainable in the future."
