X4 launch to spearhead BMW crossover onslaught at NY Auto Show

It's no secret that crossovers are one of the key vehicle types driving today's auto industry profits, and nowhere is that more true than among the world's luxury brands. BMW became one of the first players in the luxury CUV segment when it launched its original X5 in 1999, and buoyed by that model's runaway success, it followed up with the X3 in 2003, the X6 in 2008 and the X1 in 2009 (though the latter didn't make it to the US until late 2012). It's replaced the X5 twice since then and the X3 once, but the Bavarian automaker isn't about to let matters rest there.
First off, a production version of a new X4 model is expected at the New York Auto Show in April. The model was previously rumored to be earmarked for reveal a month earlier, but a new report from Autocar suggests that the previously mooted reveal date and location were inaccurate. The X4 is expected to apply the same controversial slant-back formula to the X3 that transformed the X5 into the X6, which will in turn lead to an update for the X3 as well.
But that's not all. Autocar also reports that before 2014 is out, BMW will unveil a revised X6 at the Moscow Motor Show in August, which will in turn be followed by upgraded versions of both the X6 M and X5 M. These high-performance crossovers are tipped to pack the same 4.4-liter twin-turbo V8 as the outgoing versions, albeit with higher outputs than the current models' 555 horsepower and 500 pound-feet of torque. All this, and they're still expected to simultaneously improve fuel consumption and emissions figures.

2014 BMW 4 Series Convertible is easy, breezy, beautiful

BMW debuted its 2014 4 Series Convertible today at the LA Auto Show, and the sporting two-door will feature a folding hardtop - like the convertible 3 Series before it - and be offered in 428i and 435i guises.
The 428i Convertible is equipped with BMW's 2.0-liter turbocharged inline four-cylinder engine, which pumps out 240 horsepower and 255 pound-feet of torque - good for sprinting from 0-60 miles per hour in 6.2 seconds. The 435i Convertible gets the 3.0-liter turbocharged inline six-cylinder engine, which steps up output to 300 hp and 300 lb-ft of torque. The topless 435i drops the 0-60-mph time to 5.5 seconds. Both cars come standard with an eight-speed automatic transmission, and BMW says that a manual transmission will not be offered on 4 Series Convertibles in the US market.
The 4 Series Convertible will be offered in Sport Line, Luxury Line and M Sport trims. Pricing starts at $48,750 for the 428i Convertible and $54,900 for the 435i. Head on below to peruse the (long) press release for details.

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.
