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 hints at what might become of XK after F-Type's arrival

Jaguar may move the company's XK further upmarket following the introduction of its forthcoming F-Type. The newcomer to the range easily shoulders the burden of carrying the Jaguar sportscar mantle, freeing up the XK to evolve in another direction. While speaking with Autocar, Jaguar Design Director Ian Callum said there's an opportunity to grow the grand tourer both in size and luxury.
Whether that means the vehicle will retain its two-plus-two seating configuration or swell to offer buyers even more space remains to be seen. Either way, the future will likely see the XK soften its claws moving forward. And that's no bad thing. Jaguar has a long history of building luxurious grand tourers more content to soak up miles of highway than bounce from apex to apex.
What else is in store for the brand? Callum seems to have kept his cards close to his chest, refusing to acknowledge ongoing rumors of a Jaguar crossover beyond saying the brand "had to take notice" of the popularity of the luxury SUV market.

Waymo opens its self-driving taxis to 'Trusted Testers' in San Francisco

Alphabet's fully autonomous driving unit Waymo is ready to offer rides to select passengers in San Francisco, the company announced on Tuesday. Starting later today, residents can sign up to become "Trusted Testers." With an invite to the program, you can use the Waymo One app to take rides in the fleet of Jaguar I-Pace vehicles Waymo will have stationed in the city.  Waymo describes the Trusted Tester program as a "research-focused" effort designed to help it collect feedback on its ride experience, with an emphasis on gathering information related to accessibility.    "We kicked off this program last week with a select few and are now expanding the program to all interested San Franciscans," the company said. "We’ll begin with an initial group and welcome more riders in the weeks to come." Much like it did in Arizona, Waymo won't let the cars drive without supervision right off the back. The company will have employees in the cars to ensure its fifth-generation Waymo Driver technology doesn't get lost on San Francisco's tricky one-way streets and hills. The company also told Bloomberg passengers will ride for free.   The expansion comes after Waymo recently announced CEO John Krafcik was leaving the company to pursue other projects. Some saw Krafcik as being too slow to push the company toward commercialization.  This article by I. Bonifacic originally appeared on Engadget. Related Video: This content is hosted by a third party.
