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.

The diesel premium in our Jaguar XE quickly pays for itself

Our long-term 2017 Jaguar XE 20d AWD recently returned from a 2,000-mile road trip. My wife and I took a few days to visit her family in Auburn, Alabama, and it was the first real chance anyone has had to stretch the Jaguar's legs outside of Michigan. It was also a good opportunity to see what sort of fuel economy I could wring out of the XE's 2.0-liter turbocharged diesel. The diesel engine was the main reason I chose it over our equally lovely long-term 2017 Audi A4. For me, chasing fuel economy is a great way to stay focused on the road. The XE 20d AWD is rated at 30 city/40 highway and 34 combined. The drive to and from Auburn is almost entirely highway, so I knew matching the highway rating would be easy enough. The XE has a 14.8 gallon tank, so I was looking at a minimum of 600 miles per tank and four fills for the trip, counting the initial pre-departure fill. I had two main concerns: first, this was a new route, so I didn't know how available diesel would be along I-75; second, crossing the Appalachian Mountains was going to severely cut into my overall average. The first worry turned out to be a nonissue, especially as we went further south. Not once was I forced to go from station to station looking for a lone green-handled pump. People in the South love their Cummins, Powerstroke, and Duramax-powered trucks, meaning diesel pumps were plentiful. Rolling up in a Jaguar does garner attention, though. An older gentleman even asked if I knew that I was putting diesel in the car. It seems he didn't have much faith in my reading comprehension skills. The mountains were more of a problem. There was literally no getting around them, but were west of the highest parts, so it could have been worse. The indicated fuel economy dropped by 4 mpg on the way up, from 47 mpg to 43. Still, I managed more than 650 miles from a tank, though I was starting to push my luck. We filled up for the short final leg. By the time we rolled into Auburn, the display indicated 44 mpg – pretty damn good, I'd say. It held there for the entire trip. Calculating the actual mileage revealed the computer was generous by 2 mpg, but that's par for the course. Few automakers display precise numbers. The relative ease of getting this sort of fuel economy was complemented by the price of diesel. At each one of my four stops, diesel cost less than premium, the required fuel in all of the XE's gasoline engines. According to AAA, the same is true nationwide.

We drove to the Grand Tour Lapland taping in a British beater

In October, it was revealed that the Great British Motoring Show That Is Not Top Gear was going to be filming an episode somewhere in Finland. I happen to be Finnish, which meant I immediately applied for audience tickets, and then waited for the phone to ring. It never did, but a friend of mine got two tickets of his own. By that time it was announced that the filming was going to take place "somewhere in Lapland", and more precisely hundreds of kilometers north from the Arctic Circle. Excellent! We knew just how to get there. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Last summer, we spent GBP1000 ($1230 as of the publishing date) on a running and driving, British Racing Green Daimler Six on eBay and drove it home to Finland the long way, via Scotland. (In America, this car is known as the Jaguar XJ Vanden Plas.) It was still a little bit road legal in early November, as we had attempted to get it through Finnish import inspection. It failed on the grounds of the rocker panel welds being a bit crusty, but the following one-month grace and repair period meant we could still drive it on temporary sticker plates. So, after buying a set of Nokian winter tires the previous week, we set off from Helsinki the day before the filming. This content is hosted by a third party.

There is nothing quite like driving the entire length of Finland in a right-hand-drive four-liter rebadged Jaguar in one day – still on British plates, albeit taped over. We clocked up over 1100km in the comfort of the leather interior, whisked away by the four-liter six's oomphy torque and ambient thrum; every now and then stopping for fuel, swapping drivers and wiping the headlights clean from accumulating highway muck. As we passed Rovaniemi and the Santa's Village, roads gradually got so slippery the Nokians really proved their worth. Reindeer flocked on the road, along with foxes and the single white rabbit (he did not have a pocket watch, as far as we could tell). It was not the lack of sleep doing us in, even if the hotel bed was sorely needed after finally reaching the village of Saariselka in deepest Lapland. After a celebratory beer while watching Finnish karaoke, of course. But the show! The next day we spotted the Fisker, the Boxster, and the Saab 900 driving back from taping the show's localized intro.
