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.

2013 Jaguar XF 3.0 Supercharged

Generally speaking, I don't get too upset about the growing need to replace displacement in modern cars. Sure, there are exceptions (don't you touch my 6.2-liter AMG V8), but honestly, the industry's new forced induction powertrains are all lovely, and their gains in fuel economy - when they actually make good on them - can make up for the ever-so-slight losses in performance or driving character.
But I'm having a hard time keeping my chin up with this Jaguar XF. For the 2013 model year, Jaguar has killed off the naturally aspirated 5.0-liter V8 and fitted a supercharged 3.0-liter V6 with an eight-speed automatic in its place (and even offers a turbocharged four-cylinder engine below that). That all sounds perfectly well and good, but a week behind the wheel of this British Racing Green sedan just left me missing that V8. And then some.

Seven-figure cars highlight day one of RM's Monterey auction

RM Auctions is one of several houses holding auctions during the Monterey weekend, and Friday night's festivities got quite pricey. Seven-figure vehicles were not at all uncommon during the first day of the two-day event, with the 1953 Ferrari 375 MM Spider, seen above, crossing the block for $9,075,000.
Other big earners included a pair of rare Ferraris, a 1950 166 MM Barchetta and a 1955 750 Monza Spider, which took $3,080,000 and $4,070,000, respectively. Outside of the red Italians, a 1939 Mercedes-Benz 540K Special captured $7,480,000 while a stunning, color-appropriate 1955 Jaguar D-Type took $3,850,000. We've got images of these vehicles, and a few other stunning examples of last night's auction, in the gallery above.
Thought it seems impossible, tonight's auction is expected to see even more high-dollar action. The winner of the 2012 Pebble Beach Concours, a 1928 Mercedes-Benz 680S Torpedo Roadster is expected to command over $10 million. Also crossing the block will be a car we reported on a few weeks back - a supremely rare 1967 Ferrari 275 GTB/4 NART Spyder. One of only 10 in the world, it's expected to take anywhere from $14 to $17 million when it hits the stage tonight.
