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.

Evo pits Jaguar XKR-S vs. Mercedes SL63 AMG in heavyweight droptop fight

We recently received the sad news that the Jaguar XK is ceasing production by the end of the year, but what better way to bid it farewell than with some big, smoky powerslides? The retirement of the sporty GT isn't actually the topic of the latest video from Evo - it's on hand to compete against the Mercedes-Benz SL63 AMG to see which is faster around a track. Still, we can think of it as a wonderful sendoff for the Jag.
Both convertible grand tourers get their laps around the course, and they couldn't be more different. Driver Jethro Bovingdon gets some grins out of them both, but absolutely giggles while behind the wheel of the XKR-S convertible. The SL63 AMG is the more powerful of the two, but as we know, that doesn't always matter at a racetrack. You'll just have to scroll down and watch the video to see which of them is actually the winner.

Jaguar to build 25 D-type racing cars to finish off 1956 production run

It's good to pick up where you left off, even if it's been more than 60 years. In 1956, Jaguar planned to built 100 D-type racing cars, but only 75 were completed. The missing 25 cars will now be built at Jaguar Land Rover Classic Works in Warwickshire, England, and they will all be built according to the original, authentic specifications. Customers can choose between 1955-style "Shortnose" cars and 1956-style "Longnose" versions; the prototype is of the latter specification. All of them will have the original six-cylinder XK engine, and they will come with a lot of Le Mans heritage, as D-types won the famous 24 hour race in 1955, 1956 and 1957. During their competition years, D-types were driven by such motorsport legends as Mike Hawthorn, Stirling Moss and John Fitch. This content is hosted by a third party.

Earlier, they announced they were building nine XKSS cars to finish off a production run that was cut short by a 1957 fire, and in 2015 the division built six Lightweight E-Types. The XKSS itself was strongly related to the D-type, as originally it was based on unfinished D-types sitting around in the workshop after Jaguar temporarily retired from racing. As Jaguar Classic's Engineering Manager Kev Riches says of the continuation cars: "Each one will be absolutely correct, down to the very last detail, just as Jaguar's Competitions Department intended." No pricing details have yet been announced, but they will surely follow the D-type's official debut at the Retromobile classic car show in Paris this week. Related Video:
