Teaser shot of 2015 Subaru WRX

Subaru is ready to roll out a new version of its familiar rally rocket, the WRX, at the upcoming Los Angeles Auto Show. After giving us a hint of what's to come with a show car earlier this year, the Japanese maker wants to whet our appetite just a little more with this teaser image of the production model.

The image reveals the strong influence of the New York Auto Show concept vehicle, though as is so often the case, the actual 2015 Subaru WRX will clearly be toned down a little bit — while still giving us a more aggressive package than the similar Impreza model. Among other details that come through in the teaser shot: a new front fascia and grille flanked by LED accent lamps. One thing that doesn't change: the familiar WRX hood scoop.

What remains to be learned at the L.A. Auto Show preview is whether Subaru will maintain both WRX body styles or drop the hatchback — as widely rumored — and stick with the sedan only. The teaser image is notably cropped to keep us guessing.

The Subaru WRX has developed quite a following over the years — and for good reason as it provides a performance option at a reasonably affordable price.

Among the other key questions yet to be answered: what will be under the hood. Reports out of Japan have suggested Subaru will go with a 265 horsepower version of its 2.5-liter boxer-four engine. But there's also been talk of a 300-horsepower turbocharged 2.0-liter which could be saved for the more powerful STI model.

Expect to see power continue to be routed through a manual gearbox to all four wheels. A CVT or even an automatic could be in the works but seem unlikely.

Actually, there are plenty of questions that we're looking to ask of Subaru execs at the L.A. Auto Show. For one thing: Will the 2015 Subaru WRX be based off its own platform or share the latest Impreza's underpinnings? There has been much talk of the sporty model getting a platform of its own, which could prove slightly longer and lower when we have a chance to take out the tape measure.

As much as this teaser image intrigues, it looks like we'll have to wait another week to get the answers.

Subaru is hinting it will have another secret announcement to come at the L.A. Auto Show next week. Could that be the replacement for the soon-to-vanish Tribeca crossover? Another question that has yet to be answered.
