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's latest beast is the 2018 XJR575

Hot off the rear wheels of the insanely quick XE SV Project 8, Jaguar is back with another pumped-up sedan. It's called the XJR575, and although it isn't as extreme as the aforementioned XE, it still packs a version of the company's 5.0-liter supercharged V8 that makes 575 horsepower and 517 pound-feet of torque. According to Jaguar, that will get the full-size luxury sedan to 60 mph in 4.2 seconds on its way to a top speed of 186 mph. There isn't much on the outside to tell this hot-rodded kitty from the regular XJR. The front bumper, rear spoiler, hood vents, and side skirts are all the same as the lower-powered version. It does come standard with black wheels, but they can also be optioned on a normal XJR. There are only a couple of unique points. One of which is the addition of XJR575 badges. The other is the application of a model-specific paint color. Buyers of the XJR575 will have the option to coat their cats in the Satin Corris Gray seen above, or a hue called Velocity Blue. Inside, seats are upholstered in black leather with red stitching. They feature diamond-stitched panels, as well. In the seat backs, the number 575 is embroidered. The sill plates also feature the XJR575 logo. The infotainment gets an upgrade, too, in the form of a bigger 10-inch touchscreen. Jaguar hasn't announced pricing or availability of the XJR575 yet. However, we will likely know soon, as the company will be revealing some updates for the rest of the XJ line-up for the 2018 model year. We expect to get details on pricing and availability at that time. Related Video:

Cars with the worst resale value in 2022

Car values are all over the map right now. Used vehicles that were worth a small fortune earlier this year are now coming back to Earth, but the new vehicle supply remains tight. Prices are still elevated overall, but some models have seen more severe price drops. Depreciation strikes almost every model, supply constraint or not, though a few vehicles are leading the way. New research from analytics iSeeCars found that a handful of cars depreciated more than 50 percent over five years, with the BMW 7 Series dropping 56.9 percent and an average price cut of $61,923 over that time. The vehicles with the highest depreciation — or worst resale value — over five years: BMW 7 Series: -56.9% Maserati Ghibli: -56.3% Jaguar XF: -54% Infiniti QX80: -52.6% Cadillac Escalade ESV: 52.3% Mercedes-Benz S-Class: 51.9% Lincoln Navigator: -51.9% Audi A6: -51.5% Volvo S90: -51.4% Ford Expedition: -50.7% iSeeCarsÂ’ research showed that midsize trucks, sports cars, and fuel-efficient vehicles were slowest to depreciate over five years, while itÂ’s clear that luxury brands tend to lose value much faster. As iSeeCarsÂ’ Executive Analyst Karl Brauer explained, used buyers donÂ’t value high-end vehiclesÂ’ features as much as the first owners, so resale values tend to be softer. The tech and options that made the cars so expensive and appealing new donÂ’t add the same value on the used market.

The Nissan Leaf depreciated most among EVs, dropping by 49.1 percent. The average EV depreciation is 44.2 percent, with the Tesla Model S and Model X sliding in right under the bar at 43.7 and 38.8 percent, respectively. As iSeeCars notes, itÂ’s important to be vigilant when car shopping and not let your emotions win over reason. Shiny new luxury cars look great in the showroom, but you could end up taking a bath when you try selling them a few years later on.
