Spied: 2014 Lexus IS F coupe

Lexus will rival the M4 with a high-performance coupe of its own.

Talk about killing two birds with one stone - our spy photographers have just sent us the first ever pictures of Lexus' upcoming IS coupe dressed up in never seen before F performance guise.

Lexus' last generation IS F was limited to sedan form, but the Japanese automaker will take aim at BMW's upcoming M4 with a new IS F coupe model. Based on the latest IS sedan, the IS coupe is expected to make its world debut sometime next year.

Spotted testing earlier today in Europe, the Lexus IS F coupe will arrive with a more aggressive front fascia sporting air intakes on either side. It also appears as though the IS F will receive a unique front grille treatment, which should help set the car apart from lesser IS models. Although difficult to say for certain, it looks like the IS F could arrive with a hood-mounted air scoop.

The IS F prototype spotted today was riding on sport wheels wrapped in chunky rubber. Large slotted rotors are clearly visible, indicating the IS F coupe will be capable of some serious speed.

Outback the IS F features a modest spoiler, wider wheel arches and Lexus' signature stacked F tailpipes.

Previous reports suggested the next-generation IS F would make use of the current car's 5.0L V8, but tougher European emissions standards may force Lexus to go in another direction. It's possible that we could see a smaller, turbocharged engine between the fenders of the next IS F. Whatever the case, look for the car to produce at least 450 horsepower, matching the rumored rating for the BMW M4.

The Lexus IS F coupe is expected to break cover sometime next year as a 2015 model.
