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.

2014 Jaguar XFR-S super sedan is 550-HP worth of cool

The 2014 Jaguar XFR-S was considered last year, teased last week and now has been totally let loose. The most powerful sedan the company has ever made and the newest addition to its line of R-S performance cars - following the XKR-S - and we'll be getting even fewer of them than we thought. 200 had been the rumored allotment for the US, but the official word now is that we'll see just 100.
Each XFR-S will use the same 5.0-liter supercharged V8 that powers the XKR-S, meaning a 40-horsepower and 41-pound-foot bump over the XFR for 550 hp and 502 lb-ft in total. Shifting through the adaptive, eight-speed ZF transmission gets it from standstill to 60 mph in 4.4 seconds, but for all that, it gets the same gas mileage as the XFR, aided by its stop/start system, and so doesn't get hit with a gas guzzler tax.
Other XKR-S bits have made the jump, including an upgraded suspension front and rear, the near-straight pipes for the cracking exhaust note we drank up like ambrosia and twenty-inch, six-spoke lightweight wheels that are an inch wider than on the XFR. Lateral stiffness is up 30 percent, the electronic systems have been recalibrated to handle the extra oomph, throttle response has been sharpened and can be made even sharper by going into Dynamic Mode.

Jaguar Land Rover won't get a bailout from the UK

Bailout talks between Jaguar Land Rover and Tata Steel with the UK government have ended, leaving both firms to rely on private financing to overcome the impact of coronavirus on business, the Financial Times reported on Friday. The report said that talks for an emergency funding fell through as Jaguar Land Rover (JLR) did not qualify for taxpayer support. It is the luxury car unit of India's Tata Motors and Tata Steel, both owned by Indian conglomerate Tata Group. The bailout plan, titled "Project Birch", had been authorized by Finance Minister Rishi Sunak in May to rescue companies that are seen as strategically important, with the Treasury saying it may step in to support crucial businesses on a "last resort" basis after other options run out. The report, citing a source familiar with the matter, said that the funding scheme became infeasible for Tata as it imposed strict conditions on any lending. "Tata Steel remains in ongoing and constructive talks with the UK Government on areas of potential support," Tata Steel said in an emailed statement. The UK Treasury said it would not comment on individual companies. Tata Motors did not immediately respond to request for comment. Related Video: Earnings/Financials Government/Legal Jaguar Land Rover
