In 2015, Motor Trend noted the supercharged V6 would die at the end of 2016, succeeded by a “more powerful Ingenium inline-six,” likely to be turbocharged. One year later, Car laid out a new family of Ingenium inline-sixes in gasoline and diesel versions. There would be three gas options with 300, 400, and 500 horsepower, plus three diesels with 275, 335, and 400 hp and herds of torque. In Car‘s report, the engines were meant to be here in 2017. This could be the year it finally happens.
A Jaguar spokesman in the UK told Autocar that an uptake of less than 2 percent on the S models, “Coupled with impending emissions regulation changes, it makes sense to remove these variants from sale in the UK.” When Jalopnik asked Jaguar U.S. about availability here — we aren’t a party to the imminent European emissions changes — the carmaker would only say that the engine remains available in the current XE, XF, XJ, F-Type and F-Pace.
No matter the timeline, Jaguar would want a six-cylinder to fill the gap from the 296-hp Ingenium 2.0-liter four-cylinder to the supercharged 5.0-liter V8 that starts at 470 hp. Jaguar expanded an area of its Wolverhampton, UK, engine factory to build the scalable Ingenium line. An inline-six would not only reconnect with Jaguar’s past — and the firm’s long-hooded cars remain ready to swallow them — the straight-six is lighter, has fewer moving parts, and emits less pollution than the supercharged V6. It is also compatible with front-, rear- and all-wheel drive, longitudinal and transverse mounting, and hybrid applications, so expect to see the motor migrate to the Range Rover, Range Rover Sport, and Land Rover Discovery.
Looking to either end of the Ingenium spectrum, Motor Trend reported that a 1.5-liter, three-cylinder gasoline Ingenium engine could one day serve the Jaguar XE and F-Pace, as well as the Evoque and Discovery Sport. When it comes to the V8, an Autocar piece from 2016 said Jaguar might let its 5.0-liter V8 die, and turn to BMW or Mercedes-Benz for a big engine.
