Hardcore Jaguar F-Type underway, 600 horsepower possible

Thanks to an already potent range of supercharged engines with some of the best exhaust notes available, the Jaguar F-Type is without a doubt a sublime performer. Still, there's always room to grow, and we are getting another good look from the Nurburgring at what's suspected to be an even more powerful version on the way. Spy shots of what was believed to be the Jaguar F-Type R-S first came out last spring. This time the roadster is practically uncamouflaged, though. The similarities are definitely there, and both test cars wear the same wheel design and quad-tailpipe rear diffuser. The latest one lacks the massive front splitter jutting out but gets a quite large, fixed trunk lid spoiler at the rear. You can also spot some large-diameter ceramic brake discs behind the wheels. The things happening under the bonnet might be even more interesting, though. To befit all of the exterior performance upgrades, Jaguar's supercharged 5.0-liter V8 is expected to nestle between the front wheels, and the mill is likely getting a boost in power to take output to 580 or even 600 horsepower, versus 550hp in standard form. Hopefully, the extra grunt makes the exhaust note even more intoxicating, as well.

Weekly Recap: The divergent paths of Tesla and Fisker

There's no doubt that Tesla is downshifting while Fisker has been grinding its gears. But it wasn't always that way.
In the wake of Tesla's recent success, it's easy to forget that there were once two California electric carmakers with bright futures.

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.
