Jaguar recalls 1,500 XJ sedans over brake issues

A problem with the hydraulic brakes on the flagship XJ sedan has prompted Jaguar to issue a recall. The issue, as publicized by the National Highway Traffic Safety Administration in the notice you can read below, revolves around the brake line junctions underneath the affected vehicles, which may leak fluid, thereby reducing the effectiveness of the braking system. The problem only affects an estimated 1,571 units from the 2014 and 2015 model years, manufactured between February 6 and July 23, 2014. Owners of those affected units are being notified to bring their vehicles in to their local Jaguar dealers to have the brake line junctions inspected and tightened. This issue appears to be unrelated to Jaguar's recent recall of several model lines, the XJ included, over a problem with the power steering system. RECALL Subject : Incorrect Torque of Brake Pipe Unions Report Receipt Date: NOV 19, 2014 NHTSA Campaign Number: 14V741000 Component(s): SERVICE BRAKES, HYDRAULIC Potential Number of Units Affected: 1,571 Manufacturer: Jaguar Land Rover North America, LLC SUMMARY: Jaguar Land Rover North America (Jaguar) is recalling certain model year 2014-2015 Jaguar XJ vehicles manufactured February 6, 2014, to July 23, 2014. In the affected vehicles, the brake line junctions under the vehicle may leak brake fluid. CONSEQUENCE: A brake fluid leak may reduce the vehicle's braking ability, requiring additional distance to stop the vehicle, thereby increasing the risk of a crash. REMEDY: Jaguar will notify owners, and dealers will inspect the brake line junctions, tightening them as necessary, free of charge. The recall is expected to begin on January 16, 2015. Owners may contact Jaguar customer service at 1-800-452-4827. Jaguar's number for this recall is J048. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

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.

Audi, Jag, Kia and Tesla top Strategic Vision 2014 Total Quality Index

A couple weeks ago, J.D. Power released its latest Initial Quality Study, which gave high marks to Porsche, Hyundai and General Motors, with the latter earning more individual IQS awards than any other manufacturer. Now, it's Strategic Vision's turn, and it's doling out its praise not to Porsche, but to Tesla, which wasn't even included in the JD Power IQS.
The Model S was named the best vehicle overall in total quality, while Porsche's corporate brother and endurance-racing rival, Audi, was named the best premium brand, alongside Jaguar. Strategic Vision cited the Q5 and the ancient Q7 for individual segment awards, as well as the A5, which was a mere point off the top of its segment. SV also handed out compliments for the Audi's interior work. The win for the German brand is a nice improvement over its IQS score, with which it landed above the industry average, but solidly mid-pack.
Jaguar was without a segment winner, although SV did say that the Indian-owned English brand had a number of vehicles very near the top of their segments. This is the second significant win for Jag in two weeks, after it finished second overall on the JD Power IQS a few weeks ago.
