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 hits the 'Ring wearing swirly camo

Jaguar is happy to show off its new XE sedan on its social media sites, but when testing at the Nürburgring, it's a very different story. These spy shots show the new model in camouflage to make it much harder to discern, but there are still some intriguing details to pick out.
These photos give us a really good look at the XE's quirky rear end. The sedan has a super short trunk that almost fools you into thinking its a notchback, but the top edge of the trunk is clearly visible. It's a somewhat odd-looking design with the rear glass running underneath the roof's overhang to create an integrated spoiler. Despite the camo, the front end is the same as ever with a blunt edge and sharp headlights. Jag certainly isn't afraid to try something a little different compared to the XE's competitors, notably the BMW 3 Series and Audi A4.
Some technical details about the XE are already established. This 3 Series-fighter is slated to go on sale in foreign markets in 2015 and in the US in 2016. We know that it ride's on Jag's new aluminum platform that also underpins the C-X17 crossover concept, and power comes from a pair of 2.0-liter turbocharged four-cylinder engines, available in petrol- or diesel-fueled configurations.

Jaguar recalls 7k F-Types for two seperate issues with electrical system

Jaguar is the latest automaker to join in on the recall action from this morning, as the British automaker has announced steps it's taking to remedy two separate problems. The larger of the two recalls deals with an issue related to the seatbelt sensors specifically on the F-Type (we're inquiring with Jaguar if the recall pertains to the coupe, convertible or both models). According to the notice issued by the National Highway Traffic Safety Administration, "the seatbelt harness connector which connects the Seatbelt Tension Sensor (STS) to the Occupant Classification Sensor Control Module (OCSCM) may not have been correctly wired," which could result in the front passenger air bag remaining activated even when a shorter individual (child or adult) occupies that seat. As a result, the British automaker is notifying the owners of such F-Types manufactured between August 31, 2012, and October 22, 2014, to bring their cars in to their local dealership to correct the configuration of the harness connector wire. The second Jaguar recall addresses a wider range of models but a much smaller number of actual vehicles. It affects the F-Type as well as the 2015 XF and XJ sedans, but only 272 of them in the United States. In those affected vehicles, the Front End Accessory Drive belt, Power Assisted Steering pump pulley and the battery positive cable at the alternator may detach. Since those issues could increase the risk of fire or the loss of power steering, Jaguar is calling those few affected units in to dealers to have the requisite components checked, and if necessary, repaired. Details of both recalls can be found in the notices below. Report Receipt Date: NOV 07, 2014 NHTSA Campaign Number: 14V714000 Component(s): ELECTRICAL SYSTEM Potential Number of Units Affected: 7,079 Manufacturer: Jaguar Land Rover North America, LLC SUMMARY: Jaguar Land Rover North America LLC (Jaguar) is recalling certain model year 2014-2015 F-TYPE vehicles manufactured August 31, 2012, to October 22, 2014. In the affected vehicles the seatbelt harness connector which connects the Seatbelt Tension Sensor (STS) to the Occupant Classification Sensor Control Module (OCSCM) may not have been correctly wired. The OCSCM senses whether there is an occupant in the front passenger seating position, and the STS senses whether tension on the seatbelt indicates a child restraint is being used in the front passenger seating position.
