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 readying a pop-top F-Type Coupe? [w/poll]

Typically convertibles are spun off of coupes, but sometimes it goes the other way. Like the Porsche Cayman that was based on the Boxster, the Lotus Exige spun off of the Elise, and the Jaguar F-Type, which arrived as a roadster before the coupe debuted. But if the latest reports are to be believed, Jaguar could be planning something in between.
According to Auto Express (which has, mind you, been known to stretch the rumors out some), Jaguar is toying with the idea of offering a partial convertible version of the F-Type - something Porsche would call a Targa (and which we would too if Stuttgart weren't so litigiously protective of the name). The additional roof configuration would give the F-Type three body-styles, giving its customers more choices.
It wouldn't be the only sports car to offer three roof options: There's the Porsche 911, of course. Ferrari once offered GTB, GTS and Spider versions of the 348 and 355. The Chevy Corvette has been offered in all three forms, as was the Pontiac Solstice many moons ago. But that kind of variety in roof configurations has become scarce. Jaguar's decision reportedly depends on whether it can make the business case or not. Do you think there'd be enough demand for a lift-roof F-Type?

The Jaguar E-Type Lightweight is back on the prowl after a few decades away

Sometimes procrastination has its benefits. Jaguar originally planned to build a run of 18 E-Type Lightweights for racing in the '60s. However, it was only ever to complete 12 of them. It has taken all of the intervening decades to finally get back to the project and build the final run of new Lightweights. While Jag announced the plan recently, the first continuation model was unveiled during the Pebble Beach weekend.
Coming from Jaguar Land Rover's Special Operations unit, these cars are identical to the way they left the factory in the '60s. Jag is even using the same grade of aluminum for the bodies, and the cars are fully compliant for FIA historic racing. Power comes from an aluminum, 3.8-liter inline-six with about 300 horsepower and 280 pound-feet of torque routed through a four-speed manual gearbox. Who could guess that in 2014 someone could buy a brand new vehicle from a major manufacturer that comes with Weber carbs? Though, Lucas mechanical fuel injection is an option.
While they look old, these new E-types are also a wonder of modern technology. To get things just right, the company laser scanned an original car to create the new bodies. Check out the gallery from the unveiling to see this old cat on the prowl again.
