2017 Jaguar XE 20d Quick Spin

Base models rarely get their due in the press. Big-engine, high-horsepower variants get all the headlines, but the junior version is what sells in volume. We're just as guilty here at Autoblog, with both a first and second drive of the Jaguar XE in supercharged V6 guise, and barely a mention of the entry-level, 2.0-liter diesel. So, in Perd Hapley style, the Jaguar XE diesel is the model of the Jaguar XE we're going to discuss. Yes, the volume model of the Jaguar XE is a diesel, at least for now. A turbocharged 2.0-liter gas engine, wearing the 25t badge, will arrive after the XE's early 2016 on-sale date. Oil-burners and volume are not a thing in the United States, except for heavy-duty pickup trucks. Despite that apparent contradiction, the XE 20d could find some converts. Driving Notes The biggest clue to the engine's fuel source is the tachometer, which only counts to 6,000. But you wouldn't know from the fast throttle response or the way revs climb when you mash the accelerator. All 180 peak horsepower come at 4,000 rpm, and the 317 pound-feet of torque are available from 1750 to 2500 rpm. Really, this engine is smooth. Credit the low 15.1:1 compression ratio, which also helps make the engine's aluminum construction possible. The surge of power from the turbo builds steadily instead of kicking in all at once. Jaguar's engineers focused on friction reduction with a fanatical devotion, all in the name of efficiency. One key feature is the offset crankshaft. That is, the crankshaft is located to the side of the cylinder centerline. This reduces the side load forces during the firing cycle. In the manual transmission the gears are cupped to reduce mass. A pump sprays oil directly on the cogs, which cuts back on the total amount of fluid and cuts back on friction loss due to windage. No, the manual transmission isn't coming to the US. And yes, it's really good. Not just in the cliche journalist love for the diesel-manual combo, but objectively good. That smooth responsive nature of the engine is amplified when you get to choose your own gears. So we make due with the eight-speed automatic, the 8HP45 version of the ubiquious ZF box. The coolest trick here is a pendulum-style damper in the torque converter instead of a typical spring damper. When the torque converter is locked up this cuts down on torsional vibration between the engine and transmission. And that enables low-rpm cruising and higher mpg.

Jaguar shows off production XE body in camo

Jaguar turned to Twitter and Facebook to reveal the production form of its coming XE sedan that we'll see for real at the Paris Motor Show. This is the first of a series of show-offs, Jaguar planning to wrap the bodywork in see-through camo that shows off the aluminum monocoque and other internals the company will use to promote the XE over its German rivals. That aluminum structure, which Jaguar calls iQ[Al], will also be used for other Jaguar and Land Rover vehicles.
Underneath that long bonnet and ahead of that terribly short trunk will come a series of Ingenium engines, the 2.0-liter turbocharged four-cylinder engines in diesel and petrol forms that will come in a variety of power options, and the 3.0-liter supercharged V6 that can also be found in the F-Type. Before the XE goes on sale early next year, you can click the image above to get a slightly larger view of what the The Leaping Cat's near future looks like.
