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.

The Jaguar XKSS, famed ride of King of Cool, is new again

You might remember earlier this year, when we told you Jaguar had confirmed that it would follow up the limited-run of continuation E-Types – completely new, built from scratch classics – with a new run of the impossibly cool XKSS. Those folks in Coventry weren't pulling our leg, because we're here in LA and the brand new XKSS is here, too. Actually, they're 60 years late. If you remember the story we told you when Jaguar said it'd be building these things, there were originally to be 25 cars in total. 16 were built, and the other nine were destroyed in a fire at the Browns Lane factory. Thus, nine original XKSS cars have been missing, and the nine XKSSs that Jaguar will build for a cool GBP1 million each will round out the initial production run. If you're not familiar with the XKSS, here's a little background. Jaguar won Le Mans three times in a row in a factory racer known as the D-Type. After withdrawing factory support in 1956, some privateers continued on with the car, but Jaguar didn't. That left several D-Types sitting about Browns Lane in various degrees of completion. Sir William Lyons had them converted to road spec, which involved adding such niceties as a windshield and passenger door, but otherwise they were not far removed from the Le Man-winning cars they were based on. That meant that they were, to put it mildly, a lot of car for the street. The kind of person an XKSS appealed to was stylish and adventurous, and someone who craved speed. Someone like Steve McQueen, perhaps. His old XKSS is sitting in the Petersen Museum in LA, which not-coincidentally is where Jaguar assembled us to see the wraps pulled off the new one. The "new" XKSSs are generally faithful to the original design, with the bodies hand-formed off bucks that were themselves created off an original XKSS. The body is made out of exotic magnesium, an extremely lightweight metal which is often misunderstood to be extremely flammable. It is, but much more so when it's in little pieces, like shavings; formed into a car body, it's not quite the incendiary device you might think it'd be. Even the processes to form the chassis is the same, such as the bronze welding technique used to bond its tubing. A few concessions to modern safety are fitted, however. There's a fuel cell, partly due to the additional safety it provides but also to better resist the harrowing effects of modern ethanol blend fuel.

Automakers want to stop the EPA's fuel economy rules change, and why that's a shortsighted move

With a Trump Administration looming, the EPA moved quickly after the election to propose finalizing future fuel economy rules last week. The auto industry doesn't like that (surprise), and has started making moves to stop the EPA. Ford CEO Mark Fields said he wanted to lobby Trump to lower the standards, and now the Auto Alliance, a manufacturer group, is saying it will join the fight against cleaner cars. The Alliance represents 12 automakers: BMW, Fiat Chrysler, Ford, GM, Jaguar Land Rover, Mazda, Mercedes-Benz, Mitsubishi, Porsche, Toyota, VW, and Volvo. Gloria Bergquist, a spokesperson for the Alliance, told Automotive News that the "EPA's sudden and controversial move to propose auto regulations eight months early - even after Congress warned agencies about taking such steps while political appointees were packing their bags - calls out for congressional action to pause this rulemaking until a thoughtful policy review can occur." The EPA was going to consider public comments through April 2017, but then said it would move the deadline to the end of December. That means that it can finalize the rules before President Obama leaves office. The director of public affairs for the Consumer Federation of America, Jack Gillis, said on a conference call with reporters last week when the EPA originally announced its decision that it is unlikely that President Trump will be able to roll back these changes. Gillis also said on the same call that any attempt by the automakers to prevent these changes would be history repeating itself. "These are the same companies that fought airbags, and now promoting the fact that every car has multiple airbags," he said. "These are the same companies that fought the crash-test program, and now are promoting the crash-test ratings published by the government. So, it's clear that they're misperceiving the needs of the American consumer." There are more reasons the Allliance's pushback is flawed. Carol Lee Rawn, the transportation program director for Ceres, said on that call that the automotive industry is a global one, and many automakers are moving to global platforms to help them meet strict fuel economy rules around the world.
