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 XE SV Project 8 looks like an XE, but is almost completely new

Jaguar's XE SV Project 8 is a thoroughly astonishing sports sedan. With a 592-horsepower V8, it's the most powerful Jaguar road car ever produced. And it's amazing to think that Jaguar's most powerful car is a version of its entry-level sedan. Or at least it looks that way. In reality, the majority of the body is completely unique to the Project 8. A Jaguar representative told us that only the roof and door skins are shared with the standard XE. The other 70 percent of the exterior is completely unique to the car. These changed body panels include wider fenders of course, and many of the pieces are made from carbon fiber rather than metal, but there are also some more unusual tweaks. For instance, the headlights actually had to be moved to a different position to make space for the Project 8's massive wheels and tires. The tires, for reference, are 265-mm wide at the front, and the rears are 305-mm wide. There were also some changes for style. The air vents at the front that consist of many small holes in the bumper are a tribute to Jaguars of the past. The hexagonal shape of the holes apes that of the vintage Jaguar logo, which featured the word Jaguar in an elongated hexagon. All in all, there's an impressive amount of new engineering that went into creating the Project 8. The results are, in a word, stunning. Related Video:

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.
