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.

How Jaguar optimized the Ingenium gas engine for the F-Type

At the 2017 New York Auto Show, Jaguar showed off the new entry-level F-Type, packing a 2.0-liter, turbocharged, gasoline-fueled inline-four that produces 296 horsepower, which is built in-house in the UK. It's the debut of this branch of the Ingenium engine series, and it's also the top of the Ingenium gas range; most JLR vehicles will offer a less powerful 247-hp version. We caught up with Jaguar's engineers to figure out exactly how this high-output Ingenium engine differs, and what Jaguar had to do to fit it in the F-Type's engine bay. While all Ingenium 2.0-liter gas fours share major architecture – the aluminum block and heads, as well as the bore and stroke – there are some internal differences. The most important are the low-compression pistons, which allow for more boost without detonation. The new compression ratio is 9.5:1, compared to the 10.5:1 ratio in the 247-hp spec engines. To make the most out of more boost, you need new plumbing and a way to get more fuel into the combustion chamber. So Jaguar fitted a larger twin-scroll turbocharger that's unique to this application. It features low-friction ceramic ball bearings – Jaguar says this improves transient response. There are also new fuel injectors and a fuel pump to accommodate the increased demand for gas in the high-output engine. On the back end, there's a unique exhaust system with active flaps to give it a louder bark when called for. Of course, some new hardware and more boost means the various electronic systems that control the engine needed changes. For one, Jaguar's changed the cam timing and valve lift mapping, as well as the ignition timing. The throttle mapping and transmission calibration have also been optimized for the new engine.

As far as the driver's concerned, the biggest change from the 247-hp engine to the 296-hp one – other than increased scoot – will be where the power peak is. The 296-hp engine makes peak power at a higher point in the rev range, which should reward drivers who generously prod the throttle and hold gears in manual mode. Remember, F-Types equipped with this engine will only be available with an automatic transmission. You should also remember that it's an excellent gearbox overall, with rapid, smooth shift characteristics, if the other 8-speed Jaguars are anything to go by.

Jaguar Land Rover might buy another luxury brand that it doesn't need

It seems that Jaguar Land Rover may be getting bigger in the near future. According to Bloomberg, the company is looking at acquiring some tech companies, and possibly yet another luxury car brand, provided that it fits with the current lineup of cars. On the surface, this makes some sense since Bloomberg reports that a whopping 78 percent of Tata Motors' revenue comes from luxury brands. And of course, any kind of tech acquisition could be useful considering the rapid development of electric and autonomous vehicles. But dig a little deeper, and a possible luxury brand acquisition just doesn't make sense for Jaguar Land Rover. The main reason for this is that the Jaguar and Land Rover brands have the luxury market thoroughly covered. Both brands offer full luxury lines from entry-level to high-end ( Discovery Sport to Range Rover on the Land Rover side, and XE to XJ on the Jaguar side). They also cater to every kind of luxury, from sporty vehicles such as the F-Type and SVR Land Rovers, to cushy luxury machines such as the XJ and Range Rover. So whether the company is competing with BMW or Mercedes, Jaguar and Land Rover have the bases covered. There aren't any other typical luxury brands that would actually add anything to the current lineup. In fact, adding another conventional luxury brand could actually result in the new brand poaching existing Jaguar and Land Rover buyers, rather than picking up new ones. What would make more sense for Jaguar Land Rover would be to pick up either a more mainstream brand, or an ultra-luxury marque. Neither Jaguar nor Land Rover has something that competes directly with the likes of Ford or Toyota in the mainstream game, or Rolls-Royce or Bentley at the top of the luxury heap. Picking up a brand in one of these segments would allow JLR and Tata Motors to actually expand offerings and pick up more sales, rather than having an internal competitor. What path would be ideal? Probably going even farther upmarket. Supercar makers and ultra-luxury brands continue to sell well, and there's the potential for significant profit by layering on features and content to existing platforms. Perhaps the best possibility for a high-end complement to Jaguar Land Rover would be Aston Martin. Not only does it have a strong reputation and line-up, it also could handle both supercars and luxury sedans, thanks to its Lagonda sub brand. Of course it would require Aston Martin to be receptive to a purchase.
