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 output at two UK plants hit by chip shortage

LONDON — Output at two of Jaguar Land Rover's (JLR) British car factories will be temporarily halted from Monday, due to COVID-19 supply chain disruption, including a lack of semi-conductors, the firm said on Thursday. "We have adjusted production schedules for certain vehicles which means that our Castle Bromwich and Halewood manufacturing plants will be operating a limited period of non-production from Monday 26th April," the Tata Motors-owned company said. The COVID-19 pandemic has driven up demand for semiconductor chips for use in electronics like computers, as people worked from home, and suppliers are struggling to adjust, hitting output at many automakers. Trade flows have also been affected. On Wednesday, carmaker Stellantis said it would replace digital speedometers with more old-fashioned analogue ones in one of its Peugeot models, as the fallout continues. Renault's finance chief said on Thursday that car production fell by tens of thousands of vehicles in the first quarter as a result of the shortage. Output at JLR's third British car factory in Solihull, central England, will continue, the company said. "We are working closely with affected suppliers to resolve the issues and minimize the impact on customer orders wherever possible."  

Are you the Jaguar F-Type Coupe R-S?

It's no secret that Jaguar is working on a fixed-roof version of the F-Type roadster, but now it looks like it's also developing a high-performance model for said coupe. Captured sharpening its claws at the Nürburgring, this F-Type Coupe prototype could very well be an R-S or even a more track-ready R-S GT variant.
Our biggest clue suggesting the latter are its massive brake rotors with bright-yellow calipers - similar pieces are also found on the recently introduced XKR-S GT. This would make sense, since a report in May said that Jaguar is looking to create a full line of R-S GT models in a similar fashion as the Mercedes-Benz AMG Black Series. Missing from this prototype, though, are the telltale aero add-ons we seen on the XKR-S GT - go-faster bits like the latter's front fascia winglets and rear wing, though this model is obviously still being developed. Regardless of what this new grippier, quicker kitty is called, we say "Yes, please."
