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 XJ50 Road Trip Review | Driving the XJ50's history

PARIS, France – It's motor show week in Paris, and Jaguar – which launched the original XJ here in 1968 – is indulging in a little nostalgia to celebrate the 50th anniversary that event. In the half century since, it's become the brand's definitive model – as the Wrangler is to Jeep and the 911 is to Porsche. This sexy, curvaceous and unashamedly sporty sedan set the template for generations of XJs. And to get to the show, I'm going to drive examples of each on a roadtrip from Jaguar's home in Coventry and onward to Paris, via Goodwood and Le Mans. There's new product to enjoy along the way, too, in the shape of the celebratory XJ50 trim level created to mark the anniversary. But this is really a chance to explore Jaguar's past, and how previous XJs will inform the company's future. Respecting traditions without being chained to them is a recurring theme in the XJ story and one Jaguar has, at times, struggled with. Nobody understands this better than design boss Ian Callum, who says the original XJ inspired his dream to one day design cars for Jaguar. When his moment came, however, the opposing pressures of nostalgia and innovation became apparent. He recalls seeing the clay models for the circa 2002 XJ, code named X350, styling for which had already been signed off when he started. "I asked 'this is the new one?' because, to me, it looked just like the old version," he says with characteristic bluntness. Callum's chance to truly reinvent the XJ finally came in 2009 with the current model, a car that jolted Jaguar and its customers out of their comfortable slumber. "It's nearly 10 years old now but I still think it looks good – I'm very proud of what we did with that car," he says. Professionally Callum is always looking ahead. Personally he's happy to indulge himself in what came before. He even brought his own XJC – the rare coupe version of the 70s XJ – to drive on the event. Sadly, the XJC didn't make it off the start line in England, but he's clearly enjoying the chance to immerse himself in XJ history. As am I. Given his appraisal of its retro looks, it's interesting to start in the X350. Here you encounter those aforementioned opposing forces: the forward-thinking aluminum construction (which inspired manufacturing techniques used by Jaguar to this day) and the staid styling. Like many of the heritage fleet examples here, this one is actually badged as a Daimler – to Jaguar what Maybach is to Mercedes.

Jaguar Land Rover seeks to block U.S. imports of Porsche, Audi, Lamborghini, VW SUVs

You wouldn’t know it was about Jags and Lambos, to judge by its rather dry name: In the Matter of Certain Vehicle Control Systems. But thatÂ’s the complaint Jaguar Land Rover Automotive Plc filed on Thursday to block U.S. imports of Porsche, Lamborghini, Audi and Volkswagen sport utility vehicles it says are using its patented Terrain Response technology without permission. Jaguar Land Rover, a British carmaker owned by IndiaÂ’s Tata Motors Ltd., said in its filing with the U.S. International Trade Commission that the technology helps negotiate a “broad range of surfaces” and is a key feature in JaguarÂ’s F-Pace and Land Rover Discovery vehicles. “JLR seeks to protect itself and its United States operations from companies that have injected infringing products into the U.S. market that incorporate, without any license from JLR, technology developed by JLR and protected by its patent,” JaguarÂ’s lawyer, Matthew Moore, said in the filing. Representatives of Volkswagen didnÂ’t immediately respond to emails seeking comment on the complaint. Jaguar wants to block imports of PorscheÂ’s Cayenne; LamborghiniÂ’s Urus; AudiÂ’s Q8, Q7, Q5, A6 Allroad and e-tron vehicles; and VWÂ’s Tiguan vehicles. It said there are plenty of other luxury midsize SUV and compact crossover vehicles to meet consumer demand if the SUVs are banned from the U.S. Still, the premium Porsche and Audi lines provide much of the profit VW is using to fund its investments in technology for electric vehicles, autonomous vehicles and further innovations. In addition to the four brands, Volkswagen Group owns other upscale nameplates, including Bentley and Bugatti. The International Trade Commission is an independent, quasi-judicial agency that investigates complaints of unfair trade practices, like patent infringement. It canÂ’t award damages but does have the power to block products from entering the U.S. Owners of patents and trade secrets like it because it can work faster than the federal district courts -- the typical investigation is completed in 15 to 18 months. But Jaguar also filed patent lawsuits against the companies in federal courts in Delaware and New Jersey, seeking cash compensation for the use of the technology. Those cases are likely to be put on hold once the trade commission launches its investigation. The case is In the Matter of Certain Vehicle Control Systems, 337-3508, U.S. International Trade Commission (Washington).
