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 XE promises to net 'over 75 mpg,' just not for us [w/video]

With around a month away from its world debut on September 8, Jaguar continues to issue a constant drip of updates about its upcoming XE compact luxury sedan that's aiming to take on the BMW 3 Series and Audi A4. Where the company's last bit of info focused on the car's suspension setup, this time Jag's putting the spotlight on the new model's modular platform and making some big promises about it, too. How big? Try over 75 miles per gallon big.
That's the headline figure that Jaguar is claiming for its new sedan, but it's keeping mum on just what powertrain will realize that figure. Furthermore, that result is on the European test cycle, which is more lenient than America's EPA testing regime. In any case, when the XE hits the road, Jag says it will be the most efficient vehicle from the company, ever.
That's thanks in no small part to the aluminum-intensive monocoque chassis underpinning the sedan. It's constructed from a new grade of the lightweight metal called RC 5754 that uses a high portion of recycled material. "The Jaguar XE body uses over 75-percent aluminum content, which far exceeds any other car in its class. This gives us a body structure with unrivaled low weight: it's light but also immensely strong with extremely high levels of torsional stiffness," said Dr. Mark White, Jaguar Chief Technical Specialist; Body Complete.

Jaguar Land Rover and Chery investing in Chinese plant

While the European auto market for Jaguar and Land Rover is waning, Chinese car buyers can't get enough of the British marques. To meet that demand, Tata Motors, parent company of Jag and Land Rover, is partnering with Chinese automaker Chery Automobile Co.
The two announced plans to invest $1.75 billion to build a new plant and create a new, China-focused brand. 2014 is the target for completion of the factory. Jaguars and Land Rovers built at the facility will be the first ever produced outside the UK according to the Associated Press. The JV will be called Chery Jaguar Land Rover Automotive Company Ltd.
The announcement comes less than a month after JLR announced it would open a design studio in China. It's not clear from the reports whether the two announcements are part of the same JV or two separate plans.
