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's Callum: 'Huge' opportunities with electric vehicles

Eventually, some brave innovator, with an imagination light years ahead of the rest of us mere mortals, will envision an automotive future that the rest of us can't conceive. This person will step up and tell us how electric vehicles have the potential to change our lives for the better. They'll have the guts to tell us that if we could only open our eyes, we'd see that there's a way to get from one place to another that doesn't pollute the air we breathe. They'll explain that it won't just be globally responsible, it'll be magnificent. Yes, the electric car needs a champion, a figurehead, someone so inspirational that comic book superheroes are modeled after him. Finally, that champion has revealed himself. Saying out loud what the enlightened few of us know but dare not utter for fear of ridicule, our hero has spoken. "Electrification will kickstart the biggest change in automotive design in history," Ian Callum, design director at Jaguar told Autocar. That Jaguar sees the potential for electric vehicles is welcome progress. Sarcasm aside, that Jaguar sees the potential for electric vehicles is welcome progress. Even more appealing is that Callum approaches the potential of EVs from a design angle, where the slate is essentially blank, he feels, and so much is possible. "The opportunities an electric powertrain offers are huge," Callum says, "especially in terms of the space for occupants. By removing so much of the mechanical hardware and placing the batteries in the floor plan you open up all sorts of possibilities with packaging." To peer into Callum's mind when it comes to EV design would be extraordinary to behold. In many ways, his vision truly is something most of us cannot grasp completely, having spent a long career designing some of the most desirable cars of our time for some of the most prestigious automotive brands on the planet. So when he talks about the freedom EVs present from a design standpoint, it's not difficult to get excited. A Jaguar EV isn't as far-fetched as it might seem at first. Plus, a Jaguar EV isn't as far-fetched as it might seem at first, as Callum explains. "I'm clear in my mind that an electric Jaguar would be suitable for the brand," he says. "You have to move with the times and design for the opportunities. Look at the C-X75 concept – that was a car that was designed for an alternative powertrain, and nobody had any complaints about how that looked.
