2015 BMW X4 xDrive 35i

BMW’s genre-creating X6 has been a massive (literally and figuratively) success. So it comes as no surprise that now they’ve given us a coupe version of the excellent X3. Longer, lower and with less volume for passengers and cargo, it carries a modest price premium, which is mitigated in some measure due to higher standard equipment. The version tested is the six cylinder, in M Sport trim, meaning more aggressive fascias and sills as well as different interior trim and wheels.

It is probably best not to express any aesthetic opinions in the case of such a vehicle; BMW knows that by having both the more conventional X3 and this new machine in the stable, there’s something for everyone. Inside, the dash is slightly different than its sibling, while the color and trim combinations are very appealing and of materials of generally high quality. However, there is a slight sense of insubstantiality to the cockpit; an Audi Q5 feels more robust. In the BMW’s favor, its front sports seats—set about an inch lower than in an X3—are more supportive, and its head up display superb. Back seat room is fine for two and with them folded there is still decent cargo volume, despite the fastback roofline.

The X3 is amongst the best driving small luxury crossovers on sale, with direct (if numb) steering, a very athletic balance to its chassis and a refined, quiet ride. The X4 uses stiffer springs, dampers and larger antiroll bars. Equipped with the three-way adjustable dampers, it still rides superbly while set to Comfort. Ratchet things up and it becomes more and more responsive, with very tightly controlled body motions, yet it still proffers a decent ride. It suffers far less from the “hobby horsing” ride motion of the sportier Audis as well. What is missing is that last level of organic interaction that is so well exemplified by the Porsche Macan S.

The super smooth inline six that motivates the X4 gives up basically nothing to rivals; obviously underrated at 300hp and 300lb-ft of torque, it mates seamlessly with the incredibly well programmed eight-speed ZF automatic; paddle shift commands are executed with appropriate rapidity in the more aggressive, user-selectable settings, while in more sedate use it fades into the background, slurring gear changes with world-class precision. The BMW’s brake power and feel are also excellent—important in a machine as fast and heavy (approx. 4200lbs) as the X4.

BMW has refined splitting automotive niches into a fine art; in their portfolio there is the obvious alternative of the X3, but the 3-series GT, 4-series Gran Coupe and even perhaps the 328xi SportWagen cover much the same broad mission. Those who would gravitate to this fastest of X4s must also compare it to the Audi SQ5 and aforementioned Porsche, which is barely more money if one exercises discipline when selecting options, and carries the additional brand cachet that accrues to the Stuttgart company’s products. The X4 xDrive 35i certainly can hold its head high in such illustrious company, but it’s no longer the only game in town as the X6 was when it debuted.
