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.

The Jaguar E-Pace shows off a rather cab-forward look in these spy shots

It seems the Jaguar F-Pace may be getting a little sibling soon. A smaller crossover, which we expect will be called the E-Pace, has been caught during winter testing. The SUV seen here appears to be sized like compact luxury crossovers such as the Audi Q3 and BMW X1. This also fits with Jaguar's brand director's statements that it has been considering an SUV for this class. Much of the car is well camouflaged, but taking a close look, this E-Pace has a surprisingly short dash-to-axle ratio. It's not as drastic as the electric I-Pace concept, but there's so little space between the bumper and the base of the windshield that we sincerely doubt that a longitudinal inline-4 or V6 could be lurking under the hood. And, if the E-Pace does in fact use a transverse-mounted engine, it probably doesn't share a platform with any of its rear-drive-based stablemates. It may seem strange that a company known for its rear-drive cars is considering a transverse, front-drive-based vehicle, but there are reasons it may be going this way. For one thing, Jaguar's brand director said he wasn't sure that the company's existing platforms could be scaled down far enough for such a compact crossover. That would seem to preclude using an existing rear-drive platform or developing a totally new one. In fact, it only leaves one real option in the Jaguar Land Rover line for this vehicle: the Range Rover Evoque platform, which is also shared with the Discovery Sport. It's a small SUV platform with a transverse layout. It's also currently available and should be cheap to adapt; perfect for capitalizing on the hot crossover market. We just hope Jaguar can inject some more fun into it than Land Rover did with the Discovery Sport. Using that platform also means Jaguar would probably borrow one or more engines from the Evoque and Discovery Sport. In the US, both models are only offered with a turbocharged 2.0-liter inline-4 making 240 horsepower. Overseas, both vehicles are available with 2.0-liter turbodiesel four-cylinders, making either 150 or 180 horsepower too. Considering that the 180-horsepower diesel model will arrive in the US under the hood of the Jaguar XE, it's possible that it will show up in the E-Pace as well. Don't expect any of the overseas manual transmissions to make the trip, though. Jaguar only offers a manual on the F-Type sports car in the US, so there really isn't any reason to add one to a small crossover.

Jaguar XJ220 owners will finally be able to get new tires

Bridgestone announced today that the underserved Jaguar XJ220 used-car market would finally have access to new tires. Apparently a number of years ago, companies stopped supplying road tires for the XJ220 altogether. Don Law, owner and operator of XJ220 parts and restoration company Don Law Racing, brought the issue to the attention of Bridgestone. Now, Bridgestone and Don Law have assembled a team that includes the vehicle's original chief development engineer and test driver to create a modern tire for the 213-mph supercar. Bridgestone was also able to get access to pre-production car 004 for testing purposes. The company plans to have the new tire ready for the car's twenty-fifth anniversary next year. From the sound of it, the tire will likely outperform the original one, as Bridgestone's vice president of consumer OE tires cited the advancement of tire technology over the years when talking about the project. This whole project also raises an interesting question. Are there any other supercars that don't have original equipment tire options anymore? The XJ220 certainly wasn't the only supercar of the '90s with fat tires on relatively small-diameter wheels. Also, what will happen to the tire market for modern supercars? The Bugatti Veyron famously has special tires designed to handle its extremely high top speed. It certainly is an interesting first-world conundrum, and one we're going to keep tabs on. Related Video:
