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.

Motor Trend pits Aston V12 Vantage S against Jaguar XKR-S GT in battle of the Brits

With the recent increase in higher-performance versions of already high-performance vehicles, like Mercedes-Benz and its AMG Black Series, the public is now gaining even greater access to speed and maneuverability. Two of the most recent sports cars to get their wicks turned up include the Jaguar XKR-S GT and the Aston Martin V12 Vantage S.
Both of these cars are the pinnacles of their lines, with the Jag lording over the XKR-S, XKR and XK while the Aston rules over the standard V8 Vantage S and V8 Vantage. Motor Trend has opted to pit the two rivals together for some thorough testing, and it just happened to bring along a few video cameras to capture all the action.

2016 Jaguar XJR meets 1988 XJR9-LM at Silverstone

The current Jaguar XJR is not the first Jaguar XJR. Not by a long shot. In fact there's a long and distinguished history of Jaguar production and racing models that have worn those letters over the years. So to highlight its lineage, Jaguar brought the 2016 model together with its nearly 30-year-old racing namesake to Silverstone. And it brought Andy Wallace along for the ride. Wallace won at Le Mans in 1988 driving the XJR9-LM. Designed for the race track and adorned with iconic Silk Cut livery, the XJR9 looks entirely different from the XJR luxury sedan you can buy today. And with a 7.0-liter V12 mounted amidships instead of the modern sedan's 5.0-liter supercharged V8 placed up front, they're mechanically different beasts as well. But it's not the difference in design, powertrain, or performance that Jaguar is highlighting in this video encounter. Instead, Wallace is impressed by the advancement of the lighting technology from the Le Mans racer he drove in the late 1980s to the sedan sold today. To hear him talk about how they used to use the headlights in the nighttime hours of the famously grueling endurance race is harrowing enough all on its own. Hear his story in the video above. NEW JAGUAR XJR MEETS XJR9-LM AT SILVERSTONE WITH LE MANS WINNER ANDY WALLACE AT THE WHEEL - Andy Wallace drives new Jaguar XJR and Le Mans-winning XJ-R9 LM at Silverstone - XJR9-LM – one of one million XJs now built – back on track at night for the first time since it won the 24 Hours of Le Mans in 1988 - Track session presents benefits of new Jaguar XJ LED headlights in day and night driving conditions - Wallace discusses new XJR headlight technology, which offers drivers more confidence, safety and performance at night - New short film captures all the action https://youtu.be/IgMxSkJb058 (Whitley, Coventry - 16 November 2015): Legendary racing driver and 24 Hours of Le Mans winner Andy Wallace relived his 1988 victory by taking to the Silverstone circuit to drive the Jaguar XJR9-LM during day and night back-to-back with the new 550PS, 5.0-litre Supercharged V8 Jaguar XJR. Wallace discusses his experiences in the XJR9-LM and the new XJR in an exciting new film available to view and share at https://youtu.be/IgMxSkJb058 Driving at night on the Silverstone circuit gave Wallace the opportunity to test the new LED headlights on the new XJ, which are a first for Jaguar. "Driving at Le Mans back in 1988, it was so hard to see at night," said Wallace.
