New, four-cylinder version of Jaguar F-Type spotted testing at Nurburgring.

A facelifted version of the Jaguar F-Type Coupe has been spied near the brand’s Nurburgring test facility in Germany. But instead of a snarling V6 or V8, this test mule houses a more modest 2.0-litre four-cylinder turbo engine under the bonnet.

It’s the first time we’ve seen the new F-Type testing – and indeed the first time it’s been spotted with the new engine. While the existing 3.0 and 5.0-litre engines will remain, the lower-powered versions will take the fight to Porsche’s new 718 Boxster and Cayman, both of which now utilise powerful four-cylinder turbo units.

While details are currently quite scarce, the F-Type will likely take the new Ingenium petrol engine destined for model like the XE and XF saloons. It’ll power those cars first, along with the F-Pace, Range Rover Evoque and Land Rover Discovery Sport, before appearing in the F-Type sports car. Power and torque figures haven’t been disclosed, but with the Porsches already gaining justified acclaim, it’s likely Jag’s motor will have upwards of 300bhp.

In the F-Type that should mean a 0-62mph sprint of around five seconds, with a top speed of almost 170mph. There’s a good chance it’ll be offered with manual and automatic gearboxes, too, though four-wheel drive isn’t likely to feature on the options list. A basic four-cylinder F-Type could see the car’s starting price drop below £50,000 for the first time. An entry-level 718 Cayman costs £39,878.

Along with the new engine, the F-Type will be due a series of light tweaks at some point next year, with all the usual nips and tucks inside and out. New headlamps – presumably full LED – will feature on the nose, alongside a resculpted grille and fresh bumpers.

At the rear, these pictures show a new exhaust, presumably designed to heighten the aural drama for the otherwise muted 2.0-litre turbo engine. It’s a single squared-off unit, rather than the twin or quad tailpipes found on the supercharged V6 and V8 models. We expect the production model to get updated lights and revised bumpers, too.

We’ve no images of the new F-Type convertible, but the same changes will also apply to the drop-top model. Inside, expect the F-Type to get the F-Pace’s updated infotainment system with widescreen display and pinch-to-zoom functionality. The same low-slung driving position and quality dashboard will feature, too.

We’ll have more information on the new Jaguar F-Type later this year. We don’t expect to see the full production car before the Geneva Motor Show next March, however, while a New York show debut in April is also a possibility.
