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 sends off the F-Type with commemorative 75 model

Jaguar is preparing to send the F-Type to the pantheon of automotive history. It unveiled a commemorative model named F-Type 75 that announces the end of a roughly decade-long production run with a small handful of specific design accents inside and out. Offered as a coupe and as a convertible, the 75 stands out from other members of the range with subtle emblems depicting the F-Type's silhouette positioned behind the front wheel arches. The F-Type 75 ships with 20-inch five-spoke wheels finished in gloss black, while the more powerful F-Type R 75 wears 20-inch, 10-spoke wheels with a gloss black and diamond-turned finish.  Inside, the F-Type's silhouette appears on the piece of trim positioned above the infotainment system's display and on the door sills. Every 75 regardless of body style or output comes with the Interior Black Pack and what Jaguar calls "Performance-design" front seats. While a 75-horsepower bump would have been fitting, Jaguar made no mention of mechanical changes. The four- and six-cylinder engines were dropped for the 2022 model year, so the F-Type will end its career with a V8-only range. Power for the base model comes from a 5.0-liter V8 that's supercharged to 444 horsepower and 429 pound-feet of torque, while the R benefits from an evolution of this engine rated at 575 horsepower and 516 pound-feet of torque. The base F-Type is rear- or all-wheel-drive, while the R is rear-wheel-drive-only. Jaguar will begin delivering the F-Type 75 to customers in England in early 2023 — about 75 years after the XK120 made its debut, hence the name. Pricing and availability haven't been announced yet, and Jaguar confirmed to Autoblog that details about the F-Type 75 that will be sold in the United States will be published in December 2022. The company added that 2024 will be the F-Type's last model year. As for what's next, your guess is as good as ours, but it doesn't sound like a direct successor to the F-Type is around the corner.

Cars with the worst resale value after 5 years

While the old saying that cars lose a massive chunk of their value as soon as they’re driven off the dealerÂ’s lot might not be entirely true these days, most new vehicles steadily lose value as they age and are used. iSeeCars recently released its latest study on depreciation, finding the models that lose value the fastest, and the list is packed with high-end nameplates. The vehicles that lost value the fastest over five years include: Maserati Quattroporte: 64.5% depreciation BMW 7 Series: 61.8% Maserati Ghibli: 61.3% BMW 5 Series Hybrid: 58.8% Cadillac Escalade ESV: 58.5% BMW X5: 58.2% Infiniti QX80: 58.1% Maserati Levante: 57.8% Jaguar XF: 57.6% Audi A7: 57.2% While sports cars, hybrids, and trucks dominated the list of slowest-depreciating vehicles, luxury brands accounted for all of the top ten fastest-depreciating models. iSeeCars executive analyst Karl Brauer also pointed out EVsÂ’ lack of representation on the slow-depreciating vehicles list, saying that thereÂ’s a disconnect between what automakers are building and what people actually want. The average five-year depreciation for all vehicles in the iSeeCars study was 38.8 percent. ThatÂ’s an almost 11% improvement over 2019Â’s figures, but some vehicle types perform worse than others. EVs depreciated 49.1 percent over five years, while SUVs dropped 41.2%. Trucks only fell 34.8% and hybrids 37.4%. Brauer noted that all vehicles depreciate slower than they did five years ago. Even so, EVs are not the best choice if youÂ’re looking for a vehicle that wonÂ’t feel like a ripoff when itÂ’s time to trade in. On the flip side, used EVs can present a stellar value, saving thousands over their new counterparts. Charging times and availability remain concerns for buyers in large parts of the country, but a heavily depreciated EV could be the used car value youÂ’ve been looking for. The same wisdom applies to used luxury vehicles, as the list above indicates. While new-car buyers shopping for luxury cars are set to see big depreciation during their ownership, that means the used car market is flooded with inexpensive used luxury cars. High repair costs and costly maintenance schedules are real issues that used luxury models face, however. Green Audi BMW Cadillac Infiniti Jaguar Maserati Car Buying Used Car Buying
