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.

Weekly Recap: Things you might not know about the 2015 Dodge Charger and Challenger Hellcats

If you're an enthusiast, and you don't know that Dodge spawned another Hellcat this week, you really must have been living in cave. The 2015 Dodge Charger SRT Hellcat is probably the biggest news for enthusiasts since the reveal of, well the 2015 Dodge Challenger SRT Hellcat.
But, there are some things you might not know or might have missed about the new Charger and Challenger Hellcats. For starters, reports that the Hellcat production would be limited to a low volume are not true.
"We have not capped the Hellcat on either the Challenger or the Charger," Dodge CEO Tim Kuniskis said.

Jaguar moves to trademark C-Pace name

Jaguar is again picking up the pace. The manufacturer has filed a new European trademark application with the word "Pace" in it, and this time it's all about the C-Pace. While there is no other info to go with the name, it could very well stand for a new, upcoming compact crossover that would exist as an entry-level vehicle under the F-Pace, E-Pace and the electric I-Pace (which is easily differentiated from the non-electric E-pace, as the I-Pace doesn't use internal combustion). Australia's CarAdvice suggests the eventual range-topping Pace model would be called the J-Pace, to go along with the XJ nameplate that's formed an upscale backbone for Jaguar for decades. As for sedans, the XE is paired with the E-Pace, and the F-Pace corresponds to the XF; with Volvo's crossover versions already reserving the XC name, there's no chance for Jaguar to have a matching C-Pace and XC combination in its portfolio. The C-Pace could also be a crossover coupe version based on either the E-Pace or the F-Pace. The trademark application was filed on July 9, and along with car-related goods and services, the application also covers software and charging stations, even buildings. We'll keep an eye on it.
