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 previews XF sedan ahead of New York debut

Jaguar is in the midst of an aggressive product expansion, with the new F-Type taking it back into sports-car territory, the upcoming F-Pace putting it in the crossover market for the first time and the XE renewing Jag's assault on the entry-level luxury-sedan segment. But it hasn't forgotten about its core models. The British automaker has a new flagship XJ under development, and Jag will showcase a brand-new XF at the New York Auto Show next month. But before it does, Jaguar has given us something to chew on with these teaser images: one showing the new sedan from above, and one showing the new cockpit. Now it may be hard discern much from that overhead view – which is not a typical teaser – but it's clear the new XF will feature more sharply creased body lines and a large panoramic sunroof. Meanwhile the interior looks like a modern update of the current model, borrowing some elements from the smaller XE. There's a wider infotainment display, the rotary knob for the transmission has moved toward the center, some (but not all) of the air vents appear to hide away when not in use, and there's a sportier steering wheel – though we do appear to be looking at the more performance-oriented S model. The XF, for those having trouble keeping track, is Jaguar's challenger to the likes of the Mercedes E-Class, BMW 5 Series, Audi A6 and Maserati Ghibli. It was introduced in 2007, and has been available (in certain markets anyway) in sedan and wagon forms, with engines ranging from a 2.0-liter turbo four with 240 horsepower all the way up to a 5.0-liter supercharged V8. With the New York show fast approaching, we won't have to wait much longer for a complete view of the new XF. But even before then, Jaguar promises to reveal the new XF in dramatic fashion in London: on March 24, it will drive the new sedan on two wires barely more than an inch thick suspended high above the river.

Lister LFT-C brings 666 horsepower to the Jaguar F-Type

Lister just announced a limited run of its LFT-C Jaguar F-Type conversion cars. It made 99 of the coupes in this spec, but now there will be 10 convertibles available for purchase worldwide. The LFT-C name further confuses Lister's naming for this car, which was initially known as the Thunder, then morphed into the LFT-666, and now these new convertibles are called LFT-C. We would've just stuck with Thunder all along and called this one a Thunder convertible. It makes the same 666 horsepower as the Lister F-Types before it, but that's still substantially more than the 575 horsepower out of the F-Type SVR. Lister does a lot of its own work to the 5.0-liter supercharged V8 to eke out the extra horsepower on top of what Jag is able to do with its performance division at the factory. The nice part of this aftermarket work is that it still comes with a seven-year warranty from Lister, so it's similar to a new car powertrain warranty. This should give you some peace of mind when dashing to 62 mph in just over three seconds.

Lister has designed its own suspension, exhaust, braking system and wheels to bring the rest of the car up to snuff. Carbon fiber body panels replace everything from Jaguar where possible. Other Lister design touches on the exterior include a new front bumper, front splitter, rear diffuser, rear spoiler, rear wheel arches, a new grille design and lightweight alloy wheels fitted with Michelin tires. Lister is differentiating this 10-car run by adding in a unique interior, but customers can request anything they desire on the customization front. With so few cars available, it's unlikely to see one on this side of the world after being manufactured in the U.K. That said, we asked Lister, and they said you can buy one here. Base price for the LFT-C is a cool $182,995, and that's only where it starts. We're sure customization options will allow it to skyrocket from there. The price for a base F-Type SVR Convertible is $127,725, so you're looking at a hefty premium over the donor car for what Lister has to offer. The LFT-C is available to order now.
