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.

2018 Jaguar I-Pace hits the Nurburgring in all its electric glory

Jaguar is continuing development work on the I-Pace, its first all-electric model set to arrive in 2018. Today we're getting fresh spy shots of the svelte crossover being unloaded for testing at the Nurburgring, and the I-Pace looks almost identical to the concept model and a prototype we spied earlier this year. It's expected to debut next fall at the Frankfurt Motor Show. Despite wearing Slimer-green camouflage, the I-Pace's curves and creases are evident. It's fronted by a prominent grille that's mainly for looks, angled headlights, and short overhangs. Obviously, Jag wants you to know it's working on an electric car, as the test mule wears the hashtag #jaguarelectrifies on the sides and #ipace on the hood. Subtle. Jaguar hasn't confirmed US specs, but based on the concept car the I-Pace generates 400 horsepower and 516 pound-feet of torque to all four wheels from a 90-kilowatt-hour lithium-ion battery pack. The crossover can hit 60 miles per hour in 4 seconds and has an expected range of 220 miles. Jaguar is investing in electric technology, though it's also looking to diesels and smaller-displacement four-cylinder engines as part of its future powertrain strategy. On Monday, the company confirmed plans for a 296-hp turbo four-cylinder that will be offered in the 2018 XE, XF, and F-Pace, as the well-received Ingenium engine family expands. In Jaguar parlance, the "Paces" are crossovers: The F-Pace is a midsize utility vehicle. The E-Pace is a compact crossover, and the I-Pace is an electric crossover. Try to keep up.

Jaguar's Callum refutes two XJ bodystyle rumor

Not long ago, we relayed word from Edmunds that Jaguar was planning to split its next-generation XJ sedan into two bodystyles - one model that continued the ambitious design approach fostered with the current X351-based model, and another, more upright model to better appeal to China's conservative design sensibilities.
We expressed some cynicism in the idea, noting that such a strategy "might catch more profits for the marque, but it might also represent a setback to design head Ian Callum's vision for a thoroughly modern Jaguar portfolio." Callum has been quite insistent in his belief that Jag needs to be a forward-thinking brand in terms of design, and the two-model strategy seemed to conflict with that idea. We tried to get some comment from Callum at that time, but were unable to reach him.
As it turns out, our cynicism was well-placed. Autocar says that while the next XJ will continue to have two wheelbases, Callum has denied the two-model talk, saying flatly: "I can't see us doing two bodystyles. The cost would be enormous and the message inconsistent. You have to believe in what you produce and to do two bodystyles would undermine that."
