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 Classic heading to Le Mans with vintage racers

A grid full of vintage Jaguars will rumble into France in July to race in the Jaguar Classic Challenge during the Le Mans Classic. The event should give motorsport fans plenty to watch with a bevy of pre-1966 Jags on the famous circuit, including E-Types, XKs, C-Types, D-Types, and even the company's sedans. Jaguar launched the vintage racing series last year to build on the success of the popular E-type Challenge. It continues with a five-event calendar this season but swaps out a meeting at Brands Hatch to go to Le Mans – hard to argue with that change. The drivers also get to lap Donington Park, Silverstone, the Nurburgring, and Oulton Park. Le Mans is practically a home track for these classic Jags. The British automaker dominated the 24-hour race there in the 1950s, including overall victories in '51, '53, '55, '56, and '57. "Watching a diverse array of pre-1966 Jaguars racing on the iconic circuit, some of which even raced there in period, will surely be a sight not to be missed," Tim Hannig, Jaguar Land Rover Classic Director, said in the season announcement. Again, we find it hard to argue with that sentiment.

The Le Mans Classic will be one of the major highlights of the forthcoming season that will see a diverse field of pre-1966 Jaguars going wheel-to-wheel in the competitive single-marque series. Jaguar has a long and successful history at Le Mans, with the marque first winning there back in 1951 with Peter Walker and Peter Whitehead driving the C-type - affectionately known as XKC 003. A one-two finish followed this in 1953 with the duo of Tony Rolt and Duncan Hamilton taking overall honours. Jaguar dominated Le Mans for three consecutive years in 1955, 1956 and 1957 in the D-type.

Jaguar lifts the tailgate on XFR-S Sportbrake

In the market for an amped-up Jaguar? Look for the letter R, adorning such performance models as the XFR and XJR sedans, the XKR coupe and convertible and the new F-Type R. But if it's bonkers performance you're after, you'll want to add the letter S into the mix as well. Jaguar uses the letters to connote its most hard-core performance variants like the two-door XKR-S and four-door XFR-S. And now it's applied them to the XF wagon as well, skipping the R treatment and going straight for the new XFR-S Sportbrake.
Leaked just the other day and headed for the Geneva Motor Show, Jaguar has now revealed its new power wagon in full. The XFR-S Sportbrake packs Coventry's ubiquitous 5.0-liter supercharged V8 engine boasting 542 horsepower and 502 pound-feet of torque. That's the same version that powers the XKR-S and XFR-S sedan (not to mention the F-Type R and XJR), and drives the rear wheels through an eight-speed automatic to rocket the estate to 60 in 4.6 seconds and on to an electronically limited top speed of 186 miles per hour.
That may be pretty quick, but doesn't quite stack up to the Mercedes-Benz E63 AMG S-Model 4Matic Estate whose 5.5-liter twin-turbo V8 offers up 577 hp and 590 lb-ft for a 3.6-second 0-60 time, or to the Audi RS6 Avant whose 4.0-liter twin-turbo V8 churns out 552 hp and 516 lb-ft for a 3.9-second 0-62 sprint. Though the Jaguar is only a little behind in output, it's a good second slower where it's measured. Granted that the Benz and the Audi are both all-wheel-drive where the Jaguar powers the rear only, but if four-wheel traction is how you get the power to the road, we wonder why Jaguar wouldn't fall in line. Particularly when the Jag's starting price in the UK (don't expect to see it imported here) is quoted at £82,495 - several grand more than the £76,985 RS6 but just shy of the £85,880 Mercedes gets for the E63 S-Model wagon in the UK (where the less potent 'base' version is also available as the cheapest in the bunch at £75,885).
