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 XFR-S pitted against Mercedes E63 AMG

It was Steve Sutcliffe at Autocar who got the tough job of comparing the Mercedes-Benz E63 AMG to the limited edition Jaguar XFR-S on the track and sheep-strewn British B-roads. In UK spec both Mephistophelean sedans wrangle the same 542 horsepower, but step out of the corral and things look to weigh heavily in the Mercedes' favor: it has more torque, it's lighter, it's quicker from 0-to-60 and it's less expensive.
But that's on paper. Sutcliffe was given the job to see what effect all those letters and numbers had on the real-world driving experience. One of them is "an absolute hoot at the track" with great steering and weight management, one is "magnificent." To find out which is which, watch the video below.

Jaguar's futuristic 'Sayer' steering wheel might make your morning coffee

In the not-too-distant future, it would be the only part of the car you'd actually own. If it were the subject of a surrealist painting from 1929, it might feature the tagline, "Ceci n'est pas un volant," the French word for steering wheel. Jaguar calls it Sayer and says it's the steering wheel of the future — the first voice-activated, artificial intelligence steering wheel that will be able to carry out hundreds of tasks and follow you from car to car. "Imagine a future of autonomous, connected and electric cars where you don't own a single car, but instead call upon the vehicle of your choice where and when you need it," the company says. "That's a future vision Jaguar Land Rover is exploring with Sayer, the connected steering wheel that could be the only part of the car you own." Automakers focused on developing autonomous vehicles have proposed doing away with pedals and steering wheels, but this is the first we've heard of that envisions the steering wheel, such as it is, as your veritable car keys in a self-driving, car-sharing world. Jaguar says it could order up a ride to get you where you need to go on time, and it could even advise you when you might enjoy driving part of the journey yourself. No word on whether it can sync with a toaster for breakfast, however. The concept device is named after Malcolm Sayer, a Jaguar designer from 1951 to 1970 who's responsible for the E-Type and D-Type racer, which won the Le Mans 24-hour race three times in a row in the 1950s. It will feature on a Jaguar concept called Future-Type in 2040. In the meantime, it will be unveiled at Tech Fest at Central St. Martins, University of the Arts London on Thursday, Sept. 7, as part of the automaker's "Technology with Heart" presentation. The festival is free to the public Sept. 8-10. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
