Mazda KoeruMazda will showcase a new crossover SUV concept called Koeru at the 2015 Frankfurt Motor Show in September but is revealing little information at this stage – leaving speculators intrigued as to what it could be.

Described as a boldly-styled statement in the crossover SUV segment, Mazda says the Koeru will “raise the bar for performance, efficiency and overall value”.

Boasting what appears to be a sharp, crisp and coupe-like rendition of the firm’s Kodo design language, Mazda talks about the Koeru looking powerful like a predator but with “a unique level of refined dignity”. Indeed.

Although we don’t know the details of what could be underneath, it will all be SKYACTIV tech, for good performance, efficiency and safety. All box-ticks in the competitive crossover segment

Could this be the Mazda CX-6?

The firm isn’t telling us how big it is, though – leaving speculators guessing as to where it sits in the range.

Some believe it could be a sporty CX-4 coupe-like alternative to the CX-5 crossover, but this part of the market is already well served by Mazda’s best-selling CX-5 and all-new CX-3. The firm appears to have no need for another offer in this part of the market.

Could the Koeru therefore be a larger crossover model then, one pitched to compete with models such as the Ford S-Max?

Ford has already had much success winning BMW 3 Series customers with its practical crossover MPV: might the Koeru preview a new rival from Mazda, helping push the firm upmarket in Europe and give it a premium sibling to the Mazda6 large family car?

Such a vehicle could even reference Mazda’s back catalogue. In the 1990s, we had the MX-6 large coupe.

We’ll find out more in the build up to the 2015 Frankfurt Motor Show press day on 15th September: the show itself runs from 17-27th September.
