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 will put a Covid-nuking air filtration system in future cars

Jaguar - Land Rover (JLR) is developing an air filtration system that inhibits up to 97% of viruses and airborne bacteria. Designed like a face mask for your car's HVAC system, it's built on Panasonic's Nanoe X technology. Most of the company's models (including the Land Rover Defender) currently come equipped with Panasonic's Nanoe technology and PM2.5 filtration. Nanoe X is 10 times more effective, according to the brand, because it relies on a high voltage to create trillions of hydroxyl (OH) radicals enveloped in nano-sized water molecules. Think of them as Roman guards in front of a fortress: they keep the bad out, and ensure only the good can come in. Viruses and bacteria proteins are denatured when they come into contact with the filtration system, meaning they can't reproduce or grow. The OH radicals also zap common allergens and mold, but they're harmless to humans. JLR stressed it's not relying on computer simulations to decide whether its filtration system works as designed. It asked British laboratory Perfectus Biomed to perform a test that simulates a ventilation system in recirculation mode for a 30-minute cycle in a sealed chamber. The results were encouraging: 97% of viruses and airborne bacteria were nuked. The carmaker pointed out Panasonic's Nanoe X technology has been independently proven to inhibit 99.995% of coronaviruses during a two-hour laboratory test carried out by French immunology lab Texcell. Future models from Jaguar and Land Rover will use this technology, though a representative for both companies declined to tell us when it will reach production, and which nameplate(s) will inaugurate it. Meanwhile, Honda launched its own coronavirus killer across the pond. It's a cabin air filter sold as a genuine replacement part that consists of four layers, including one coated with an active substance of fruit extract that inactivates nearly 100% of the viral aerosols it captures. It's available in Europe through Honda dealers, but it won't be sold in America. Jaguar Land Rover

2018 Jaguar XF S Sportbrake Review | Who needs a crossover with a wagon this sexy?

PORTO, Portugal — SUV and truck mania is real — just ask the 63 percent of American buyers who opted for the high-riding vehicles last year. But there has been a recent groundswell of alternative options in the burgeoning wagon segment. Sure, there are lower-end wagons such as the tried-and-true Subaru Outback ($25,895) and the new-kid-on-the-block Volkswagen Golf SportWagen ($21,580). But the 2018 Jaguar XF S Sportbrake competes more closely with the stalwart Mercedes-Benz E400 ($64,045) and the stylish Volvo V90 Cross Country ($52,300). This begs the nagging question: Could wagons become a serious thing in the States? We spent a day bombing through Portuguese backroads to find out how the Sportbrake fares among its niche competitive set. The 2018 Sportbrake is a wagonized version of the second-gen XF sedan that arrived in 2016. While the first-gen model only offered a wagon variant for the European market, the new Sportbrake is a global vehicle that brings a more streamlined, aluminum-intensive architecture to the table and finally gives American wagon lovers the Jag they've been craving. First off, the essential reason we're here: the cargo area. Activate the power tailgate (which uses a one-piece composite tailgate, just like the F-Pace), and the opening reveals a flat surface on all sides with 31.7 cubic feet of storage. Fold the rear seats down, and volume expands to a considerable 69.7 — an increase of 12.6 and 38.4 cubic feet, respectively. For comparison, the Volvo V90 Cross Country offers 19.8/53.9 cubic feet, and the Mercedes-Benz E400 Wagon has 35.0/64.0 cubic feet. Folding the Sportbrake's rear seats down produces a nice, flat expanse for cargo, with no obtrusive humps or bumps on the side. Standard rear air suspension keeps things level when loaded up. Onward to the front seats, where the cabin brings the XF's familiar design with the dashboard rimmed in a curved ribbon of wood veneer — a pleasant touch that offsets the otherwise blase textured aluminum bits on the dash and shifter surround. Of course, there's the love-it-or-leave-it cylindrical shifter that rises from the center console, a confounding bit of design that leaves most PRNDL traditionalists cold. So, too, does the plastic starter button on the dash, one of the few unsatisfying puzzle pieces in the otherwise agreeably finished interior. But fire up the engine, and it's easy to forget these quibbles.
