Jaguar spotted testing hardcore F-Type SVR

Jaguar keeps churning out more and more potent versions of the F-Type. And if these latest spy shots are anything to go by, it's got an even more powerful version in the works. Spotted undergoing testing near the Nurburgring is what appears to be a more hardcore variant of Coventry's shapely sports car. Beneath the usual swirly camouflage we can make out a reshaped front end with a deeper splitter and bigger air vents, along with a giant rear wing affixed to the tail atop an enlarged diffuser and quad exhaust tips. The wheels look like they're mounted to a lowered suspension and pack bigger carbon-ceramic brakes as well. Following the Range Rover Sport SVR, Jaguar is likely to label the new F-Type performance flagship as an SVR as well. Jaguar spokesman Richard Agnew confirmed to Autoblog that the R-S badge that previously adorned the most potent Jags is being phased out. That leaves the SVR badge as the most likely to appear on the back of this beast once it reaches production, although that much has yet to be confirmed: "As we stated when Jaguar Land Rover Special Operations was formed," says Agnew, "it is our intention to create a high-performance Jaguar SVR and we are currently evaluating what product to launch first." Nameplates aside, we're more interested in what this amped-up F-Type is packing underneath. We'll likely be looking at an even further enhanced version of the company's signature 5.0-liter supercharged V8 pumping out a good 600 horsepower, which would eclipse both the 550 hp in the F-Type R and the 575 in the Project 7 speedster – potentially driving all four wheels. We'll just have to sit tight to find out, but in the meantime you can scope out the spy shots in the gallery above for a closer look at what Jaguar's Special Vehicle Operations division has got in the cooker.

Jaguar models could rev with inline-six engines again

Rumors are swirling once again that Jaguar might return an inline-six engine to its lineup. Autocar claims Jaguar Land Rover will use the modular Ingenium engine family to create a 3.0-liter straight-six. The new motor will replace the automaker's current V6. As with the Ingenium 2.0-liter four-cylinder, JLR will likely offer the powerplant in gasoline- and diesel-fueled versions. A rumor in May 2015 also suggested JLR would create an Ingenium-based turbocharged 3.0-liter inline-six and a 1.5-liter three-cylinder unit. According to Autocar, the engine bay in the XE, XF, and F-Pace can already fit the longer engine. The automaker isn't talking, though. "We can't comment on future product one way or another," company spokesperson Nathan Hoyt told Autoblog. Jaguar built much of its performance legacy with straight-six-powered vehicles. While the C-Type and D-Type were winning races with the engine layout, practically every Jaguar production model used them as well. Today, straight-sixes are less common. BMW continues to use them, and Mercedes-Benz reportedly also plans to offer one soon. While Autocar's report is still just a rumor, the move to an inline-six could be advantageous for JLR. For example, using an Ingenium-derived design could simplify manufacturing by allowing the company to build the powerplant in one factory alongside the 2.0-liter version. Returning to a design with such an important heritage for Jaguar would also make life easy for the brand's marketing team because it could link the new engine to past racing glory. Related Video:

Jaguar Land Rover to drop supercharged V8 for turbocharged BMW power

There are few things that sound as good as Jaguar's 5.0 liter supercharged V8. As great as it is when the supercharger whines or the exhaust cracks and pops on throttle lift-off as the air pressure equalizes, the basic design dates back to the '90s. Plainly, the engine isn't as efficient as it needs to be, but designing a new V8 from the ground up is an expensive proposition. Instead, Automobile reports that Jaguar Land Rover is set to use a twin-turbocharged V8s supplied by BMW. Scalable architecture is all the rage as automakers streamline designs in order to save costs. For example, Jaguar's current supercharged V6 is quite literally a V8 with two holes missing. They didn't even change the length of the block. It seems both of those designs are on their way out, with the V6 being replaced by a inline-six closely related to the company's inline four. It seems that rather than designing an new and expensive V8 for their top of the line models JLR, is sourcing from BMW. From 1994 to 2000, BMW owned Land Rover. A few models, including the Land Rover Range Rover, used BMW engines then and in the initial years of Ford's JLR stewardship. It seems things have now come full circle. BMW currently makes a twin-turbo 4.4 liter V8 that produces anywhere from 440 to 600 horsepower, depending on the application. Automobile says that a new 4.0 liter V8 is in the works and that it will most likely be the engine that JLR uses. Expect it to be more powerful, more fuel efficient, and lighter than what both BMW and JLR currently offer. This seems like a win for both companies. BMW gets to offset the cost of a new motor while JLR, a smaller company, doesn't have to invest in a whole new architecture. As automakers search for ways to cut costs, expect collaborations like this to continue. Infiniti and Mercedes-Benz both share a four-cylinder engine. Ford and GM have worked together to design a shared 10-speed automatic. While we may lament the loss of that wonderful Jaguar Land Rover engine, we can still be happy that they haven't abandoned the V8.
