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.

Here's what a front-row seat looked like in 2014 Mille Miglia

From 1927 to 1957, the Mille Miglia was one of the great, romantic European road races of the golden era of motorsports. The cars were fast, beautiful and loud but also extremely dangerous and regularly claimed drivers' lives. After two fatal accidents in '57, the event finally had to reform and came back in 1977 as a historic rally held over the course of several days. That didn't make things boring, though, and Xcar found that out firsthand with a front-row seat to this year's race in a 2015 Jaguar F-Type R Coupe.
Xcar was actually following the Jaguar team this year that included Ian Callum and Jay Leno in an XK120, which we previously got a glimpse of when it was covered on Jay Leno's Garage. Where Leno focuses on a more personal story of competing, this one takes a more macro view. You really get an idea of how crazy the Mille Miglia still is, and while the F-Type is way too new to actually compete in the rally, it can still wear an event sticker and drive with the vintage racers.
One amazing fact about today's Mille Miglia is that if you're competing in the event, there are basically no rules. The roads are technically still open to traffic, but the police shut down intersections and provide a rolling roadblock. Xcar's F-Type alternated between following on the course with the classics and snipping off chunks of the route to watch the participants arrive at each stop.

Jaguar F-Type US order guide loose online

An alleged US order guide for the 2014 Jaguar F-Type has made its way online courtesy of the good people at F-TypeClub.com, documenting everything from wheel color options to special equipment packages. From the looks of things, buyers will be able to choose from a total of eight wheel designs in sizes ranging from 18 inches on the base model all the way up to 20 inches. While most of those rollers are available in either silver or black finishes, the 20-inch blade-style wheels are not only forged, but come with carbon-fiber trim. Fancy.
Depending on trim, F-Type buyers will get to choose between two types of seat, including a set of performance-style 14-way power adjustable thrones, complete with seat belts in black, red or tan. Other fun tricks include available power folding side view mirrors and a 770-watt, 14-speaker Meridian sound system.
