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 could yet offer more hardcore F-Type R-S

Jaguar pulled a fast one on us all when it unexpectedly shoehorned all 550 horsepower of the 5.0-liter supercharged V8 from the XKR-S into the new F-Type Coupe to supersede the existing V8 S model with the F-Type R. But that's just the beginning, according to the latest intel coming from the UK.
According to Autocar, in speaking to Jaguar design director Ian Callum during the coupe's unveiling at the LA Auto Show, the British automaker could yet offer R-S and R-S GT versions of the F-Type. Just what mechanical changes those would bring when the F-Type R already packs the company's top engine remains to be seen, but given that the same engine also powers the flagship XJR performance saloon, we could envision Jaguar developing an even more powerful version for R-S versions of the little coupe and big sedan.
The GT version, meanwhile, would likely offer more extreme aero and a lighter form for the truly performance-obsessed. Considering that the new top-of-the-line F-Type is already pushing the hundred-grand mark, you can bet any R-S and R-S GT version would approach double the base F-Type's $65k sticker price.

Junkyard Gem: 1985 Jaguar XJ6

The Series III Jaguar XJ was built for the 1979 through 1992 model years, the final chapter of a quarter-century of the iconic original Jaguar XJ (though production of the straight-six model ended in 1987). Thanks to notoriously troublesome electrical systems and rapid depreciation, but blessed by stay-of-execution-obtaining beauty, most of these cars were parked under blue tarps in driveways before the end of the 1990s... awaiting repairs that never came. Here's one that I spotted in a San Francisco Bay Area self-service wrecking yard over the winter. If you were serious about driving a Jag during the easy-money 1980s, you needed the optional wire wheels. That showed those rubes in the BMW 735s and Mercedes-Benz 500SELs what real class was all about. The 4.2-liter version of Jaguar's legendary straight-six engine made 176 horsepower in 1985. That was six fewer than the 735i's six and eight fewer than the 500SEL's V8. However, the XJ6 cost $32,250, versus $36,880 for the BMW and $51,200 for the Benz. Given that the Jag offered at least as much (and maybe more) status on the street, its price tag looks like a pretty good deal. Of course, the electrical stuff would have a few issues, but so what?
