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 Land Rover to badge vehicles based on horsepower

Add Jaguar and Land Rover to the list of automakers changing their nomenclature due to the realities of engine downsizing. Spy photos of an unreleased Jaguar F-Type model show a badge reading P380 AWD. The letter P evidently refers to Petrol (British for gasoline), and 380 is the engine's horsepower. According to Auto Express, the entry-level F-Type will be badged P300, indicating the power output of its 2.0-liter turbocharged four-cylinder engine. Land Rover is expected to follow suit with the new badging nomenclature. Diesel models will get a D instead of a P, while electric and hybrid models will get an E badge, along with a number corresponding to total system power. So, expect the I-Pace to sport an E400 badge on its hind end. One question we have, though, is how the disparity between mechanical, metric and imperial horsepower will be dealt with. While such power-specific badges are arguably unnecessary, we expect the trend to proliferate as engines continue to get smaller but turbocharging and electrification keep horsepower climbing. At least JLR's badges are easier to understand than the messy way Audi plans to rename its models or the way BMW completely dismisses actual engine size in its naming convention.

Jaguar F-Type coupe to cost more than convertible?

Jaguar may price the much-rumored F-Type Coupe above the F-Type Convertible, if a report from Australia's Drive is to be believed. What makes Jag think that such a pricing strategy would work? Porsche. Take a look at the German manufacturer's consumer site, and you'll notice that the Boxster is less expensive than the Cayman, despite being essentially the same car.
It's a fair point, and a price premium does a good job of emphasizing the sporting chops of the coupe over the open-air experience that normally entitles convertibles to higher MSRPs. It's unclear just how closely Jaguar will follow Porsche's example, though.
Both the Cayman and Cayman S boast an extra ten horsepower over a Boxster or Boxster S, and while this bump in grunt is negligible in every situation but an argument over which is "best," it isn't something to be ignored in the F-Type, particularly as cranking more power out of its supercharged engines should be a rather simple matter.
