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 might not sell many XF Sportbrakes in the U.S., but here's why it's trying

One of the wonderful surprises of this year was when we learned that the U.S. would receive the XF Sportbrake wagon, and — less of a surprise — it's as much a looker as the previous generation. And while we're never one to look a gift car in the grille, it did seem strange that Jaguar would attempt to bring a wagon to the U.S., especially when it already had a similarly sized F-Pace crossover. So we spoke with Jaguar CEO Joe Eberhardt, Jaguar Design Director Ian Callum, and Jaguar's head of product planning in the U.S. to find out what prompted the company to bring the XF Sportbrake here. There were a few key reasons. One was simply that the folks at Jaguar really like the car, and they know that journalists like wagons. That doesn't exactly pay the bills for a car, but the enthusiasm is good. According to these people at Jaguar, though, they do believe there is a market for the car, and they expect to sell most of them on the coasts. Obviously, even if Jaguar sees a wagon market, it's still going to be much smaller than for crossover SUVs. But no matter how small that market is, Jaguar has an extra advantage for bringing the wagon here. The company knew it was going to make a wagon regardless of whether it would come to America, since the wagon market in Europe is so strong. In fact, Jaguar expects that half of XF sales in Europe will be Sportbrakes. So the majority of the engineering costs will be covered from those sales. The folks at Jaguar also told us that the car wasn't difficult to homologate for the U.S., so the cost of bringing it here was minimal. So in the worst case scenario that has the XF Sportbrake hardly selling in America, Jaguar isn't going to be seriously hurt. And if it's a success, then it's even more of a success. So the XF Sportbrake isn't purely a passion product, but that's OK. It means consumers have one more option to the multitude of crossovers in the U.S., and enthusiasts have the chance to own a super cool wagon. Also, although the XF Sportbrake is currently only available in America in top-level 380-horsepower S trim, Jaguar said lower trim levels and lower-output engines, all at lower prices, will be available here in the coming year or so. Meaning there will be even more ways to satisfy your wagon itch. Related Video:

2016 Jaguar XF to hit 60 mph in 5 seconds, lead with cutting-edge infotainment

Since the second-gen XF's unveiling last week in an epic publicity stunt over London's Canary Wharf, the details on the new four-door have been rather scarce. That changes now, with the Jaguar revealing just about everything we could hope to know... aside from the price and fuel economy. As we covered in our original post, Jaguar has trimmed the weight for both rear- and all-wheel-drive variants by 132 pounds and 265 lbs, respectively. That means that, regardless of engine output, the two-wheel-drive model tips the scales at just 3,770 lbs, while the AWD XF slips in at 3,880. This was mainly done by way of aluminum construction – the 13th element constitutes 75 percent of the XF's structure – although ultra-high-strength steel also plays a role. Jag claims these elements not only reduce weight – which is almost perfectly distributed, with a "near" fifty-fifty ratio – but increases torsional rigidity by 28 percent. The new XF should be just as agile as the brand's namesake, thanks not only to the reduced weight and stiffer structure, but also to a new chain-driven all-wheel-drive system that's both lighter and more efficient than a traditional version. Impressive though that may be, the brand's Intelligent Driveline Dynamics system is the standout here. IDD manages the torque split, diverting power to the rear axle until it predicts, through factors like yaw rate, steering angle and lateral acceleration, when torque should be shifted to the front wheels. Moreover, the AWD system features Adaptive Surface Response, which takes the place of the old XF's winter driving mode. It monitors road conditions, modifying the behavior of the sedan's systems as needed. The second-gen sedan comes to the US in 340-horsepower and 380-hp variants – torque remains fixed at 332 pound-feet – courtesy of Jaguar Land Rover's familiar 3.0-liter, supercharged V6. The new XF's straight-line performance should be just as entertaining as it sounds, too. The rear-drive, 340-hp XF will hit 60 in 5.2 seconds, while the rest of the range can get there in 5.0. That marks a significant reduction compared to the first-gen V6 models, which used their 340 hp to sprint to 60 in a more leisurely 5.7 to 6.1 seconds. Regardless of output, the rear-drive XF will outrun both the BMW 535i and Mercedes-Benz E350 (we're still waiting on performance figures for the 329-hp E400, so Jag's RWD dominance may not last), which take 5.5 seconds and 6.5 seconds, respectively.
