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.

2015 Jaguar F-Type R Coupe [w/video]

This is it. This is the nasty cat we've been hankering for most. Whereas the Jaguar F-Type convertible remains the company's purest expression of lifestyle fun and expendable income, it's this coupe version that originally stole our eyeballs and never gave them back when it debuted as the C-X16 Concept way back at the 2011 Frankfurt Motor Show. And now we've had an early turn at driving the most potent variant, the Jaguar F-Type R Coupe.
This F-Type Coupe design is so utterly visually stunning that, even if something dynamically or functionally was not really to our liking, we would still want to have the wherewithal to buy one and garage it, if only to stare at it - not unlike our reaction to the 2007-2009 Alfa Romeo 8C Competizione coupe, then. Whether such beauty needs to be in the form of this $99,000 mondo 542-horsepower R version or the more attainable six-cylinder trim is an open question.
In case you need reminding, that's 542 horses maxing out at 6,500 rpm, along with 502 pound-feet of torque on tap between 2,500 and 5,500 revs. There is no indicator yet as to whether Jaguar will eventually come out with an R version beyond the 488-hp V8 S for the convertible, either, so this may well be our only shot at such hair-brained antics in this small Jag. Small and not quite light, we should add - despite its all-aluminum goodness - the F Coupe rings in at 3,638 pounds. That sort of heft is one thing on the street, but it's quite another on a twisty roadcourse, and we aimed to figure out if the coupe's 80-percent greater stiffness versus the open F-Type (along with its higher attendant spring rates) were enough to make a big difference.

2014 Jaguar XJR unleashed just ahead of New York show [w/video]

Just a week after teasing us with the first image of the car, and mere hours before revealing it to the public at the New York Auto Show, Jaguar has pulled the wraps off of its 2014 XJR super sedan.
The British automaker has confirmed that the XJR will be kicking out a full 550-horsepower and 502 pound-feet of torque from its supercharged 5.0-liter V8, affording the sedan a 0-60 mile per hour sprint of 4.4 seconds and a top speed of 174 miles per hour. A ZF eight-speed automatic transmission will still allow for respectable fuel economy, as Jag estimates ratings of 15 miles per gallon city and 23 highway.
Newly tuned dampers and stiffer spring rates, along with an electronically controlled differential should ensure that the massive power of the engine isn't wasted in transition to the road. Jaguar has also tweaked steering software and hydraulics, with the goal of increased road feel, response and overall feedback. 20-inch signature wheels carry wide Pirelli rubber (265-section up front, 295 in back) to keep the XJR planted.
