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.

Harry bravely drives Jaguar XJ-S V12 1,000 miles to Monaco

There are a great many cars we'd like to take on a transcontinental journey – especially across Europe. And a good portion of them would probably be grand tourers with twelve-cylinder engines. We're just not sure we'd be as brave as Harry Metcalfe, who drove his 1980 Jaguar XJ-S V12 from his home in the UK all the way down to Monaco. Don't get us wrong, the XJ-S looks like a rather comfortable ride, and with the V12 is surely both smooth and powerful. It's just that Jags didn't have the best reputation for reliability back then, and we'd have been at least a little worried that we wouldn't make it all the way across France on this trip. Nor are we sure we would have wanted to without air conditioning. The model in question, as you'll find out if you watch the video, is an early 1980 example, produced just before Jaguar updated the line with the High-Efficiency versions. As such, it's got a bit more power and shorter gearing than later models. The XJS (as it would later be labeled) would undergo a number of updates over the following years, and would stay on the market until 1996 when the XK came along to relieve it. By Harry's reckoning, his early XJ-S was every bit as good as the Porsche 928 and other front-engined GTs of the era, and would have been more fondly remembered if it hadn't had to live in the shadow of the E-Type that came before. You'll want to watch the 17-minute video of the journey, undertaken for a cover story to appear in the September issue of Octane, to see for yourself. Related Video:

Jaguar Land Rover is going to call itself 'JLR' and spin off brands

Embracing the current popular philosophy that less is more, the executives at Jaguar Land Rover plan to officially rename their company “JLR” and to create a new “house of brands” that will emphasize name equity and refocus its vehicle offerings. In simple terms, the British-based, India-owned company will split into four separate brands: Range Rover, Discovery, Defender and Jaguar. While this shift may appear to be essentially a function of marketing and dealership bookkeeping, the over-arching reason is to give some of the brands more visibility. Details of the plan, which would reconfigure showrooms in Britain into discrete brand footprints, were discussed this week at a presentation by JLR CEO Adrian Mardell. “The reality is Range Rover is a brand and so is Defender,’” said creative officer Gerry McGovern. “Customers say they own a Range Rover. In luxury, you need absolute clarity. Land Rover Range Rover SV Autobiography doesnÂ’t give it. We love Land Rover, but there isn't as much equity as Range Rover, and Defender is increasing massively.”  Underlying the effort is plans to reinvent Jaguar as an electric-only luxury brand, Mardell said that this was “unfinished business” for him since he joined Jaguar 32 years ago. “The Jaguar of 32 years ago is where weÂ’re going back to and the right place for us to be." He further acknowledged that JLR had been “quiet” recently in the face of semiconductor chip shortages, but allowed that that situation was easing at his company.
