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.

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 likely moving HQ to Britain's most iconic racetrack

Jaguar Land Rover looks increasingly likely to make Britain's iconic Silverstone race track the automaker's new headquarters. There isn't a final deal in place yet, but the British Racing Drivers' Club, which owns the circuit, plans to have the membership vote on whether the negotiations should move forward, according to Autosport. BRDC leaders already presented the plan to members, and they were open to the idea. "The response was favorable so we will now set up an EGM for the members to vote and give the board a mandate to proceed with the deal and continue with the negotiations with JLR," BRDC president Derek Warwick told Autosport. There's no guarantee yet that JLR actually completes the deal. "There's still a lot of work to do to get the deal to where both sides are happy and more importantly what's right for the BRDC and its members." Warwick said. Rumors in early December suggested JLR was among the firms submitting bids to purchase the track, and the automaker allegedly offered 22.7 million pounds ($34.1 million at the time) for it. The company would also reportedly invest nearly $80 million to renovate the site, including adding a museum, experience center, hotel, and offices. The track would still be open for motorsport, too. Silverstone has hosted the Formula One British Grand Prix many times over the decades, and organizers signed a 17-year deal in 2009 to keep things that way well into the future. Series like the FIA World Endurance Championship, MotoGP, and British Touring Car Championship also compete there. Related Video:
