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.

Land Rover could build a baby Defender on a platform sourced from BMW

The collaboration between BMW and Jaguar-Land Rover started out small, it was originally limited to motors for electric cars, but it might not stay that way for long. The Tata-owned British sister companies will allegedly rummage through Munich's sizable parts bin to build nearly half a dozen cars scheduled to come out during the 2020s. According to a report by British magazine Autocar, Jaguar has started designing two small cars that will join its growing family of Pace-badged soft-roaders. They'll be new additions to the firm's portfolio, not replacements for existing cars. One will be a regular crossover, while the other will be a swoopier, form-over-function four-door model ostensibly marketed as a coupe. Both will slot at the very bottom of the Jaguar portfolio, below the already pretty small E-Pace, in a growing market segment where the competition is fierce, and profit margins are thinner than an i3's tires. Here's where BMW apparently comes in. Instead of developing a platform from scratch, the two crossovers could ride on the hybrid-ready, front-wheel drive FAAR architecture found under the third-generation 1 Series hatchback and the upcoming 2 Series Gran Coupe. If we believe an earlier report claiming Jaguar and BMW will also share engines, most of the hardware found under the sheet metal will have German genes. All-wheel drive will certainly be available, and it could also come from BMW. The same platform -- and, presumably, the same engines -- would provide the basis for a Land Rover-badged model positioned in the same segment. Autocar learned it will be to the next-generation Defender (pictured) what the Mercedes-Benz GLB is to the G-Class. Some key design cues will carry over, but the two models will share absolutely nothing under the sheet metal. The soft-roader could resurrect the Freelander nameplate when it goes on sale during the 2020s. Looking even further ahead, the front-wheel-drive platform the next Mini Countryman and X1 will utilize could find its way under the replacements for the next Range Rover Evoque and Discovery Sport. These plans could very well change; the Evoque and the Disco Sport barely entered their second generation, so they're not due for a replacement until the second half of the coming decade. While neither company has confirmed or denied the report, the partnership makes sense from a business standpoint.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
