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.

Xcar focuses on famed Jaguar test driver Norman Dewis

If you have any interest at all in motoring history, especially when it comes to European sports car racing from the '50s and '60s, do absolutely whatever you can to set aside 38 minutes for this interview with former Jaguar test driver Norman Dewis from XCar. Dewis had a hand in developing the British brand's vehicles from 1952 to 1985, and as expected over that time, he amassed some fantastic stories. Xcar did a great job of teasing a few of those great tales out of him here. From the very beginning, Dewis was gifted with a natural talent to read a car as a test driver. When he was just 16, he was taken out on his first chance to evaluate a vehicle and picked out even more intricacies than his instructor. Dewis eventually wound up at Jaguar, and that's where his career really took off. Among his many accomplishments there, he had a role in developing disc brakes both for racing and the road, set multiple world top speed records, and helped bring the E-Type to the world. Dewis even made the famous overnight drive in an XKE convertible from England to display it at the Geneva Motor Show. Dewis tells a first-hand account of being in the Jaguar paddock during the tragic accident during the 1955 24 Hours of Le Mans that took the lives of dozens of spectators. It's a story that we usually can only read about or watch in black-and-white films. Hearing Dewis' side really brings this history to life.

Jaguar turns down offers to join V8 Supercars, questions AMG, Volvo participation

Rumors have swirled in recent weeks that Jaguar may be the next manufacturer to join the V8 Supercars racing series, made popular in Australia but now well-known in other parts of the world as well. Sadly, Jag's participation is not to be. In fact, it would be "insane," according to Jaguar Land Rover Asia Pacific Managing Director David Blackhall, for it to accept either of the two offers it has received to bring Jaguar into V8 Supercars.
Not only is Jaguar not interested in entering V8 Supercars, says Blackhall, it also fails to understand the recent entries from AMG and Volvo. "I don't know what it does for AMG to get flogged by a V8 Commodore week after week, but it's their brand, their issue. And the same thing will happen to Volvo to be honest."
Judging by Blackhall's statements to motoring.com.au, after not-so-serious consideration, the automaker decided the monetary commitment it would take to compete for wins would be more than any potential exposure would be worth, despite the fact that Jaguar has a 5.0-liter V8 to go along with what would seem to be a tailor-made rear-wheel-drive chassis. For what it's worth, one offer would have had Jaguar putting its name across an engine made by someone else, an option that was flatly turned down.
