In fact, we know the engine will come in at least two versions, one rated at 340 horsepower and the second, exclusively reserved for the F-Type, rated at 380 horsepower. Both engines are based on technology developed for Jaguar's supercharged 5.0-liter V-8, so expect both versions to come with direct fuel injection, variable valve timing and extensive use of aluminum to reduce weight.
As for the lower-output V-6 engine, expect to see that debut in XF and XJ models, but whether or not that includes models bound for the United States remains a mystery. All XF and XJ models sold here currently come with Jaguar’s 5.0-liter V-8, which makes a minimum of 385 horsepower and 380 pound-feet of torque in normally-aspirated trim.
That makes the supercharged 3.0-liter V-6 a step backward in performance, although it will likely serve up better fuel economy than the current V-8. For markets that will soon get a turbocharged 2.0-liter four-cylinder in XF and XJ models, the supercharged V-6 will offer a more economical upgrade path than the 5.0-liter V-8.
