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.

Ferrari and Jaguar dominate the 2017 Arizona Auctions

The 2017 Arizona Auctions took place this past weekend, and one look at the results should be a reminder that big-name auto auctions are no place for mere mortals. Aside from the fast paced nature – seven auction houses moved 3,486 vehicles across the auction block – the rarest and most desirable cars sold for more than most people will make in a lifetime. There were around 20 cars that sold for at least $1 million, with Bonhams topping the list with a $7,370,000 1963 Jaguar E-Type Lightweight. Despite $259.8 million in sales, Hagerty reports that 2017 was only the second biggest weekend in the Arizona auction's long history. The figure was up $9 million from 2016's total, but much of that increase can be attributed to the 12-percent increase in the total number of cars auctioned. The average selling price was $89,601, with the vast majority of vehicles selling for less than $100,000. Aside from the 1963 Jaguar E-Type, there were a number of rare and noteworthy vehicles for up for grabs. RM Sotheby's $6,600,000 1939 Mercedes-Benz 540K Special Roadster was the runner-up in value, followed closely by a $6,380,000 1952 Ferrari 340 America Competizione Spider from Bonhams. The various top-10 lists were awash with Ferraris and other European automakers, though much of the lower-end sales were populated by classic American autos. Most of the top sellers were built before 1970, though the occasional newer model (1995 Ferrari F50, 2005 Porsche Carrera GT, 2006 Ford GT) made it through. Based on 2017's overall theme, it appears that interest on cars from American automakers is on the rise. Hagerty notes that a number of 1980s American sports cars like the Chevrolet Corvette and Pontiac Firebird did surprisingly well. Look for the 2018 auctions to see if the momentum continues.
