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.

BMW could add all-electric Mini, X3 SUV

BMW's Mini sub-brand will add a battery-electric variant as the company looks to meet stricter emissions mandates around the world, according to an interview Bloomberg News conducted with CEO Harald Krueger. BMW is also planning an all-electric version of its X3 SUV and may start greening up models as large as its 7 Series sedan, though that prospect is far cloudier. The all-electric Mini will be available to the public as soon as 2019, while the battery-electric X3 SUV will likely start sales the following year. BMW didn't offer specifics about how much those models would cost or far they will be able to travel on a full electric charge, with Krueger only saying single-charge ranges would be "competitive" with other all-electric models. BMW this summer upgraded the battery in its i3 electric vehicle and boosted its single-charge range by about 40 percent to 114 miles. As for demand for BMW's i sub-brand vehicles, US sales of the i3 through September fell 27 percent to almost 5,800 vehicles, while sales of the i8 plug-in hybrid are down 19 percent to about 1,100 units, BMW said on Monday. Meanwhile, word got out earlier this year that BMW may dedicate the Rocketman concept hatchback as Mini's entrant to the electric-vehicle sector. BMW actually used a Mini as its first electric testing vehicle. The Mini E was produced in 2009 and 2010 before giving way to the BMW ActiveE, which was actually a converted 1-Series vehicle. Eventually, BMW started producing the i3. Related Video: Featured Gallery Mini Rocketman Concept View 25 Photos News Source: Bloomberg News Green BMW MINI SUV Electric

2014 BMW X5

Is Better Than Ever Still Good Enough?
By now, all but the staunchest of traditionalists have moved past the shock and horror of seeing their favorite automotive brands branching into categories and segments that break with their previously accepted norms. In other words, you and I don't really care all that much if the BMW M3 is powered by an inline six or a V8, or whether it boasts a turbocharger, just so long as the end result is an awesome car. Similarly, we don't get all hot under the collar seeing that same M3 share space on the showroom floor with a brace of SUVs and crossovers... or, as BMW continues to insist, Sports Activity Vehicles.
Time, as they say, heals all wounds, and the BMW X5 has been around long enough, having first seen the light of day in 1999, that anyone offended by its existence has since gotten over it. Plus, the X5 is a legitimately nice vehicle to drive, offering such desirable qualities to family men and women as seating for up to seven, all-wheel drive and a commandingly tall view of the road. For the enthusiast set, the X5 serves up a taut chassis and powerful engine options.
