The 2014 Lexus IS sedan has been turning heads and dividing public opinion since we first drove it. Then, as now, we knew that a revamped IS F would be in the offing at some point, but until today we had no idea what form the Lexus would take.

Our first ever batch of 2015 Lexus IS F spy shots has just come across the transom, and the camouflaged coupe – that's right, there are just two doors this time out – is awfully intriguing at first glance. A much more aggressive front end is prominent, as is the slinky roofline that finishes in a pert rear end. The signature IS grille is still in effect here, at least in terms of the shape, and while the headlamps are covered up, we'd expect some variation of the slash-like units on the 2014 IS.

Hinting at the car's performance intentions are large slotted brake rotors with significantly sized calipers, all tucked in behind dark-finish wheels. Quad exhaust tips and a retractable spoiler can be seen at the back of the car.

Unfortunately, we still don't know what to expect in terms of engine – there's some evidence that the current car's 5.0-liter V8 won't meet European emissions standards. A turbocharged V6 of some kind would certainly match up with the reported mills in the upcoming BMW M4, however, and the hood scoop seen above lends some credence to that thought process. In any case we'd expect north of 450 horsepower in terms of output.
