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 details new Ingenium four-cylinder engines [w/video]

When Jaguar lifted the veil on its new XE sports sedan earlier this month, it only revealed details on one engine - that being the 3.0-liter supercharged V6 in the flagship XE S. But we already knew that the British automaker's new entry-level model will offer many other powertrain options, and now it has revealed a little more.
Jaguar has been developing a new family of 2.0-liter four-cylinder engines it calls Ingenium, which will be offered in a wide array of configurations and specifications. In advance of its debut at the upcoming Paris Motor Show, the Leaping Cat marque has announced the specifications of the two diesel versions. The first will offer 161 horsepower and 280 pound-feet of torque and some of the best environmental credentials on the market. There will also be a more potent version with 177 hp and 317 lb-ft, which Jaguar says is "one of the highest torque outputs in the class." Either way, both versions feature variable exhaust valve timing, cooled low-pressure exhaust gas recirculation and selective catalytic reduction technologies to help meet the stringent Euro 6 standards.
That's all well and fine, but considering that Jaguar doesn't offer diesels in North America, the chances of these oil-burners making their way Stateside seem slim. But if you watch the video below, you'll also find basic specs on their gasoline counterparts as well. Like the diesels, they're turbocharged and displace 2.0 liters, but in petrol form, they offer 197 hp and 206 lb-ft of torque, or 236 hp and 250 lb-ft.

Autocar compares new Maserati Quattroporte to Jaguar XJ

Autocar's Steve Sutcliffe took the 2014 Maserati Quattroporte on a spin along snowy mountain roads to test it for a specific brief: as a limousine for the chauffeured class. It's sporting credentials are impressive: Twin-turbocharged 3.8-liter V8, 532 horsepower, 475 pound-feet of torque in casual circumstances that rises to 532 lb-ft in overboost, a 0-to-60 mile-per-hour sprint of 4.7 seconds and a top speed of 191 mph.
However, citing Maserati's desire to not just increase its sales to 50,000-per-annum by 2015, but to sell many more of its cars in China, Sutcliffe wanted to find out if the livery side of the Quattroporte could match its sport sedan side. So after taking the pilot's seat and trying out the sport settings, Sutcliffe hops in back to test out the CEO's seat.
Then he compares the Quattroporte against the long-wheelbase Jaguar XJ with its supercharged V8, a sedan that's 15,000 pounds less expensive than the Maserati. It doesn't take long for him to find that one of them is a clear winner when it comes to transporting VIPs. To find out which one, enjoy the video below.
