Next-gen BMW X3 caught in the cold

The BMW X3 might be getting a bit long in the tooth, but fans of the sporty CUV can rest easy knowing that Munich hasn't forgotten about it. The third-generation crossover was caught squeezing in some end-of-season winter testing by our trusty spy photographers. According to our spies, the 2017 X3, code-named G01, will be underpinned by a new modular platform that promises more space in the cabin and better visibility out. Beyond that, the next X3 will get a range of B-series engines; expect four- and six-cylinder options, as well as a plug-in-hybrid option (eventually). Our spies also report that BMW will finally offer some more performance-oriented options, starting with an X3 M40i and eventually expanding into a X3 M. Beyond the oily bits, it looks like the X3's looks are set to evolve, growing slightly compared to its predecessor. BMW's trippy camouflage, though, prevents a closer analysis of the next-gen CUV's styling. Check out our full gallery of spy shots to see what's coming for the X3.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

2015 BMW X4 xDrive28i

When BMW unveiled the X6 back in 2008, critical reviews were mixed, to say the least. By all accounts, the heavyweight crossover actually drove quite well, but the idea of a BMW X5 that traded a lot of functionality for polarizing looks and a higher price tag seemed like a tough sell. Then it went on sale and quickly proved to be a cash cow. Today, the German brand has moved over a quarter million of the things worldwide. Unsurprisingly, this success has moved BMW to double down on its so-called Sport Activity Coupe by adding a smaller variant. The all-new X4, while not a bad steer in and of itself, makes even less sense than its big brother, particularly when viewed alongside BMW's other offerings. Like the X6 and X5, the X4 borrows heavily from another of the brand's utility vehicles, in this case, the less-costly X3. Also like the X6, this new crossover-coupe's styling is sure to cause a schism among critics and consumers alike. You can probably guess where the majority of the Autoblog camp falls. To be totally frank, the exterior of the X4 is simply ghastly to this writer, particularly in this tester's eye-catching paint. Admittedly – and much like the X6 – there's not much objectionable from the A-pillar forward, where the X4 has a lot in common with the X3. It's only once moving towards the rear that things well and truly go wrong. There's just so much visual mass, and it's been made worse by the way BMW designers wussed out. Bear with me. Compare the profile of the X6 with the X4, and pay particular attention to the roofline on the bigger vehicle. The angle of the roofline is noticeably more dramatic on the X6, which comes at the expense of second-row headroom (an oft-criticized area for the big boy). For the X4, designers tried to have their cake and eat it too, maintaining second-row headroom but with a coupe-like profile. The result is an X4 that is bulbous and uncouth from the B-pillar back, more hunchbacked Gran Turismo than svelte Gran Coupe. BMW might have been better served if its exterior work had followed the stylings of the cabin, which is more or less a clone of what's on offer in the X3. Material quality is still great, with soft-touch plastics and available cool-to-the-touch brushed aluminum throughout. I really dug the Ivory White Nevada leather and contrast red stitching on this test vehicle, as it provided an eye-pleasing departure from the sea of blacks, grays and tans so typical of the luxury crossover market.
