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.

U.S. issues new tariff threat, this time against British-built cars

WASHINGTON — Britain is the United States' closest ally but their long friendship may be sorely tested as the two countries try to forge a new trade agreement after Britain's exit from the European Union. U.S. Treasury Secretary Steven Mnuchin said on Saturday in London that he was optimistic that a bilateral deal with Britain could be reached as soon as this year. But Mnuchin gave up no ground after a second meeting with his UK counterpart, Sajid Javid. Javid has insisted that Britain will proceed with a unilateral digital services tax, despite a U.S. threat to levy retaliatory tariffs on British-made autos. Mnuchin told reporters after Saturday's meeting that such taxes would discriminate against big U.S. tech companies like Alphabet Inc's Google, Apple, Facebook and Amazon. The UK Treasury declined to comment on the private meeting. The divide highlights the challenges ahead as the Trump administration seeks a new bilateral agreement with Britain, part of a broader push to rebalance relations with nearly all its major trading partners. The stakes are high — British Prime Minister Boris Johnson has pegged the trade deal with United States as a way to ease the pain of breaking with Europe, Britain's largest trade partner. U.S. President Donald Trump, has promised a "massive" trade deal to support Brexit, the product of a populist movement similar to his "America First" agenda. The goodwill and special relationship the two countries have enjoyed for decades may not count for much, experts say. "Trump is not going to be doing Johnson any favors," said Amanda Sloat, a senior fellow with the Brookings Institution in Washington. "He's not going to give him a trade deal without major concessions." Even before the digital tax issue arose, the Trump administration threatened to tax foreign car imports, which could hit British-made Jaguar, Land Rover, Mini, and Honda Civic hatchback cars. Stiff U.S. trade demands include increased access for U.S. farm goods, concessions that will be difficult for Britain's entrenched natural food culture to swallow. The United States also wants Britain to change the way its National Health Service prices drugs and allow in more U.S. pharmaceuticals, which could prove politically unpopular for Johnson's government. Washington's demand that London block Chinese telecoms equipment maker Huawei Technologies Co Ltd for national security reasons could also cloud talks.

Jaguar Land Rover data leak reveals employee records, upcoming layoffs

A massive data leak has revealed the personnel files of hundreds of employees at Jaguar Land Rover's factory in Solihull, England. The documents reveal details such as sick days used, disciplinary issues and — most notably — red lines indicating potential firings in the weeks or months ahead. In total, the personal records of more than 600 workers were released. JLR is scrambling to contain the crisis. The breach was first reported by the Huffington Post UK, with the automaker initially claiming the story was "fake news." That publicity gaff certainly didn't help matters, especially for employees staring at their name with a red line slashed across it. Last month, the British automaker had said it would be eliminating roughly 1,000 employees at factories in the U.K. The Solihull plant, which produces models like the Range Rover, Range Rover Sport, Jaguar F-Pace and Jaguar XE, was among those mentioned in the statement. JLR, which is owned by the Indian conglomerate Tata Motors, is facing a steep drop in sales, particularly in its home market. The main culprits include a huge slump in sales of diesel-powered vehicles - a vital part of JLR's business in the U.K. and throughout Europe - along with fears about how the upcoming "Brexit" will affect business operations. In the HuffPost UK story, one worker called the situation "disgusting" and "embarrassing," adding that people at the factory now know whether they, or their colleagues, are soon due to lose their job.
