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.

2023 J.D. Power APEAL Study shows new-car customer satisfaction scores slip

J.D. Power survey results have been slightly up but mostly down for automakers this year, literally. In February, the 2023 Vehicle Dependability Study showed an overall decline compared the 2022 a month before the Customer Service Index Study did the same. The trend reversed in June with a better overall score on the 2023 U.S. Electric Vehicle Consideration Study than in 2022, then declined again the same month on with a lower overall score on the 2023 Initial Quality Study. The declines continue with the 2023 J.D. Power U.S. Automotive Performance, Execution and Layout (APEAL) Study, overall satisfaction among the 84,555 respondents down two points overall compared to 2022, to 845 out of 1,000 points. Because last year's score dropped compared to 2021, this year marks the first consecutive decline in the study's 28-year history. The study tries to "[measure] owners' emotional attachment and level of excitement with new vehicle" after 90 days of ownership by asking new owners to rate 37 attributes in 10 areas around the vehicle, such as the feeling they get when they hit the accelerator. Satisfaction with nine of the attributes is down this year versus last, fuel economy the only segment to show better results with 15 points more satisfaction. Styling and infotainment are big drags on satisfaction. Responses to new car exterior looks tallied 888 points, down from 894 last year, the largest drop in this year's study. On the digital side, less than half of those surveyed this year said they prefer using a manufacturer's built-in infotainment. From 70% of respondents in 2020 preferring to use a manufacturer's in-house software to play audio instead of Android Auto or Apple CarPlay, that's 56% in 2023. Going all-in on Google appears to have the best effect. J.D. Power said that vehicles with both Google's Android Automotive Operating System (AAOS) and Google Automotive Services (GAS) "score higher in the infotainment category than those with no AAOS whatsoever. AAOS without GAS receives the lowest scores for infotainment of the three categories."  Frank Hanley, senior director of auto benchmarking at J.D. Power, said, "Despite the technology and design innovations that manufacturers put into new vehicles, owners are lukewarm about them. While innovations like charging pads, vehicle apps and advanced audio features should enhance an owner’s experience, this is not the case when problems are experienced.

Jaguar design boss admits X-Type was a mistake

History has a way of repeating itself, especially in the auto industry. When Jaguar was owned by Ford, the British brand attempted to field a competitor for the BMW 3 Series, called the X-Type. Based on the bones of a Ford Mondeo, it aped the styling of Jaguar's flagship model, the XJ, while borrowing liberally from the Ford parts bin. That was 2001.
Now, in 2013, Jaguar is planning a new 3 Series challenger based on the platform previewed by the C-X17 Concept, while Ford is attempting to take the latest Mondeo upmarket. The moves have both brands recognizing where, why, and how the X-Type failed. "It didn't look mature or powerful or anything. It was just a car," Jaguar's current head of advanced design, Julian Thomson, told PistonHeads. Basing the X-Type on a front-drive car while giving it styling that was meant for a rear-driver lead to proportions that "were plainly wrong," Thomson told PH. Ford's European head of quality, Gunnar Herrmann, added that the X-Type was "a fake Jaguar, because every piece I touch is Ford."
For what it's worth, the X-Type's successor in the segment will sport rear-drive, with plenty of input from Ian Callum. Thomson described the new model, which would challenge the 3 Series as having, "Big wheels right to the ends of the car, low bonnet, short overhangs, very low cabins." Sounds good to us.
