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, Brian Johnson and Lord March pick 10 top Jaguars

An automaker with as rich a heritage as Jaguar is bound to create a few experts along the way... and some divergent opinions, too. So on the eve of the debut of the new XE, Jaguar brought together three experts to whittle down the long list of classic Leaping Cats to just ten.
For this gargantuan task, it brought in Ian Callum (who, as the company's chief designer, knows a thing or two about Jaguars), Lord Charles Henry Gordon-Lennox (the Earl of March and founder of the Goodwood Revival) and Brian Johnson - who may be better known as the frontman of AC/DC, but also a classic car enthusiast, collector and racer in his own right.
So what did the designer, the nobleman and the celebrity choose? The SS100, XK120 (namely number NUB 120), the C-Type that competed at the 1953 Mille Miglia, the D-Type that won at Reims, the Mk II sedan, the E-Type that served as the Geneva show car, the one and only XJ13, company founder Sir William Lyons' personal XJ6 S1, the TWR XJS touring car and the 1988 Le Mans-winning XJR-9.

Land Rover plotting high-performance Disco Sport, Evoque

Jaguar Land Rover is getting serious about performance with its new SVR line of high-output machinery. We've already seen the Range Rover Sport SVR, and we're anticipating more to follow with SVR versions of the new Jaguar XE, Range Rover LWB, outgoing Land Rover Defender and plenty more. The lineup will eventually include performance versions of most, but not all of the British automaker's products. But while the smallest Land Rovers may not get the full-on SVR treatment, JLR reportedly has something in the works. According to Australian website Motoring, Land Rover is watching the segment and considering its options. It sees Audi with its SQ5, BMW planning performance versions of the X3 and X4, and Mercedes plotting an AMG version of the GLC that's set to replace the GLK. The question is just what Land Rover will do. Both the Discovery Sport and Range Rover Evoque are based on the same D8 platform that incorporates transversely mounted inline-fours, so fitting something larger might be prohibitive, but a high-output turbo version of the new Ingenium four-cylinder engine design could do the trick. Considering what the likes of Volvo and Mercedes have managed to do with their high-strung turbo fours, Land Rover's approach could prove to be no slouch at all – even without the 5.0-liter supercharged V8 powering the flagship SVR models. In related news, Autovisie – the automotive section of Dutch newspaper De Telegraaf – projects that an SVR version of the Jaguar F-Type will be among the high-performance models coming up next. Slotting above the F-Type R with its 550 horsepower, the F-Type SVR will be even more powerful. The Project 7 speedster packaged a 575-hp version of the same supercharged V8, potentially pointing the way forward for future SVR models.
