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.

Jaguar sets a lap record at a near-forgotten French race track

If asked to name any race track in France, most racing and car enthusiasts would probably answer the Circuit de la Sarthe, known for the 24 Hours of Le Mans. Then there's the famous Magny-Cours or Circuit Paul Ricard, but not everyone remembers the Circuit de Charade near Clermont-Ferrand. This challenging track has been called a "twistier and faster" version of the Nurburgring, and in its original five-mile form, it barely had any straights. Formula 1 races were held there in the late 1960s and early 1970s, but safety concerns saw the French Grand Prix moved to Paul Ricard for most of the 1970s and 1980s, alternating with Dijon-Prenois. Later on, the track was essentially halved during modernization work, and it's now largely used for track days. The full length circuit was last used in 1988. This history lesson about a seemingly forgotten French race track is due to one good reason: Jaguar has returned to the venue to set a lap time with a new, all-wheel drive XE. The flying lap of the full five-mile track was the first one in 30 years, and the 4-minute, 9-second lap time set by Belgian racing driver Vincent Radermecker now stands as a record. Due to changes and the fact that the track originally utilized parts of public roads, the lap now included two gateways and a roundabout. Unshockingly, those weren't around in its racing days. The comparisons with the Nurburgring are apt, as Radermecker's comment confirms. "I set the production (sedan) record at the Nurburgring in the XE SV Project 8 last year and this lap was every bit as demanding. The longest straight is barely 600 metres, so I can see why drivers used to call this the French Nurburgring." The Jaguar used for the record lap is an XE 300 Sport, which is powered by Jaguar's 300-horsepower 2.0-liter four-cylinder turbo engine. It hits 60 mph in 5.4 seconds, and the average speed on the Charade lap was 72 mph. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

2017 Jaguar F-Type SVR First Drive

Jaguar's F-Type SVR has a special new exhaust. I drove the car in Monterey, California, where there's this tunnel right in the middle of town. You see where I'm going with this. The pipes attached to the "normal" F-Type R's supercharged 5.0-liter V8 is a flatulent riot, one of the most flamboyant wind sections in modern exhaust-dom. And then Jaguar's Special Vehicle Operations, the group of madmen responsible for the Project 7, comes along and rips it all out for the SVR. The room is needed for a rear diffuser, see. So a new system is fabbed using two fancy lightweight alloys, Inconel and titanium. A pair of mufflers sprout where one used to be. More. Better. Louder. Yes, all of that. Geez it's loud. And there's this tunnel, remember. Enter it and lift from the throttle, and it sounds as though there are some kids stowed away in the trunk tossing handfuls of M-80s out the back. "Big report" is what it'd say on the box if the F-Type SVR were a firework. It's dramatic, perhaps excessive. Scratch that – it's definitely excessive. This F-Type is only the second full-production effort from Jaguar Land Rover's SVO, the first being the Range Rover Sport SVR, and so it's also the first Jaguar SVR ever. Whereas that Range Rover combines quickness with surprising cross-country abilities, the F-Type SVR has a singular mission: Go faster. And so, with a tweak of the electronic limiter and some other fiddling, voila!, suddenly the coupe can reach a top speed of 200 mph. The convertible is not far behind at 195. Although there aren't many places in the world where you'll actually want to probe those max velocities, the engine's 575 horsepower and 516 pound-feet of torque are plenty to risk your license. The SVR adopts many of the engine improvements that hoisted the Project 7 to the same power level but bests that very special car's torque figure thanks mostly to new intercoolers. Remember, the regular F-Type R is only good for 550 hp. Only. What a world we live in. Aside from the added power, this is much more of a range-topping special trim than it is a significantly different model. Like the R, the SVR comes only with all-wheel drive and an eight-speed automatic transmission. Operating it in manual mode is more pleasant, in part because the paddle shifters behind the wheel are made out of aluminum instead of plastic like on other automatic F-Types.
