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.

This classic Jaguar XJ has a 720-hp ungentlemanly secret

Forget Tawny Kitaen. If you want to make a Jaguar XJ rock, just do what this guy did: stuff a heavily modified and turbocharged General Motors V8 under the hood, and take it to the track.
The video calls this Series 1 XJ a sleeper, but with its open exhaust and obvious turbo whistle, the once-gentlemanly sedan is anything but. The owner says that the engine is GM LQ9 V8 that has been stroked to 402 cubic inches putting out around 720 horsepower with 12 pounds of boost (in standard form, this 6.0-liter V8 was used in the second-gen Cadillac Escalade). Check out the video below to see what that kind of power does for this classic Jaguar in the eighth-mile.

2017 Jaguar F-Type SVR is a very fast, very angry kitty

Well, Jaguar has gone and done it. The British marque hit the perfect sweet spot with its newest F-Type, the range-topping SVR, landing squarely in a price/performance segment its butt-engined rivals from Stuttgart aren't playing in. Confirming our previous reports, the new SVR will debut at the 2016 Geneva Motor Show with the latest version of Jaguar Land Rover's 5.0-liter, supercharged V8. With some fettling by the team at JLR's Special Vehicle Operations, the engine has been boosted to 575 horsepower, 25 more than F-Type R. Torque is up from 501 pound-feet to 516 pound-feet, while the 0-60 time has dropped from 3.9 to just 3.5 seconds. And yes, 200 miles per hour is possible with the hardtop – the convertible will only do 195. That means you'll be getting more power, more torque, a quicker run to 60, and a higher top speed than an all-wheel-drive Porsche 911 GTS, but for just $5,000 more, a figure that's quickly erased by Porsche's insane options catalog. The Jag can't stand up to the 0-60 performance of 540-hp, 2.9-second 911 Turbo or the high speed of the 205-mph Turbo S, but with prices for the SVR Coupe starting at just $126,945 ($129,795 for the droptop), it's going to cost anywhere from $33,000 to $62,000 less than the Carreras. With only modest increases in output, it's pretty clear SVO made some bigger changes to score an extra 14 mph on the high end and cut 0.4 seconds off the 0-60 time. At its most basic level, the SVR is 55 pounds lighter than the F-Type R, thanks in large part to the new Inconel titanium exhaust, which cuts 35 pounds of fat (and makes for a more sinister note, we're told). Tack on the optional carbon-ceramic brakes, along with a few carbon-fiber accents, and the overall savings sits around 110 pounds. JLR is also promising faster performance from the eight-speed ZF automatic transmission, which still sends its power to all four wheels. Speaking of which, the new 20-inch forged aluminum alloys are shod in wider Pirelli PZero – 265s in front and 305s in the back, compared to 255/295 on the R model. There is also the usual array of aesthetic and aerodynamic changes. You can check out the more aggressive body work in the full gallery, but know the changes contribute to improved cooling and cut the coefficients of drag and lift by up to 7.5 and 45 percent, respectively, when the adjustable rear wing is in its aerodynamic down position, and 2.5 and 15 percent with the wing up.
