Two-box BMW X2 breaks from X4 and X6

Our first batch of BMW X2 spy photos has revealed something interesting about the German brand's newest compact CUV. Unlike the even-numbered X cars – the X4 and X6 – these shots show a traditional two-box CUV, rather than the plunging roofline of those lifted, four-door coupes.

With a two-box design then, what is there to differentiate the X2 from the X1? For a start, while this is a similar to the X1 shots we've seen, the D-pillar and rear window are significantly more aggressive without compromising the traditional CUV design. That design backs up our spies, who claim the X2 will be a sportier version of the upcoming X1. But while the look will be similar, expect the two cars to share powerplants and drivetrains.

That means the four-cylinder B48, used in both the Mini Cooper S and other BMW products, will be on offer at launch. That engine will be joined by turbocharged triples within the first 12 months on the market. An M Performance model will also be offered, boosting the B48's output from around 230 horsepower to an even 300 ponies. That'd put the X2 on a collision course with the Audi RS Q3, although it won't be quite as angry as the Mercedes-Benz GLA45 AMG.

While the X2 could debut as early as the 2016 Geneva Motor Show, our spies claim the X2 won't hit dealerships until the second half of 2017. Check out our array of spy images up top, and pay particular attention to the D-pillar and rear window, to see the major differences between the X2 and X1.
