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.

Ian Callum makes the Jaguar C-X75 concept street-legal

Unveiled at the 2010 Paris Motor Show, the Jaguar C-X75 could have been one of the British brand's wildest and coolest models. It received the green light for production, got canned, and resurfaced in the 2015 James Bond movie Spectre before disappearing for good. However, not everyone has forgotten it: Callum, the design firm founded by former Jaguar design boss Ian Callum, has made a C-X75 street-legal. Precisely how Callum's customer ended up with a C-X75 remains a mystery. The example modified is one of the four surviving stunt cars built by Williams Advanced Engineering for Spectre, so it might be the one that auction house RM Sotheby's offered at its Abu Dhabi sale in November 2019. The car was estimated to sell for anywhere between $800,000 and $1.2 million; it ended up not selling during the auction. Regardless, Callum was the right person to take on the Herculean task of making an obscure, experimental supercar street-legal, as he led the team that designed the model. His company made hundreds of small but significant changes including replacing the glass, adding a quieter exhaust with catalytic converters, making tuning changes to the supercharged, 5.0-liter V8, and fitting additional switches inside. Interestingly, the stunt cars were built with foam door mirrors. These had to be replaced with real mirrors fitted with turn signal repeaters. The team also took advantage of the tear-down to make visual improvements, such as reducing and aligning the panel gaps. The C-X75 received a new coat of paint, and engineers made changes to the suspension system — they notably adjusted the ride height. It helps that this version of the C-X75 uses an engine already approved for road use; the V8 has powered the Range Rover, among other cars. Callum's street-legal Jaguar C-X75 will make its public debut at the Bicester Heritage Scramble event held in England on April 21, 2024.
