DC fast charging standard on 2015 BMW i3 EV

The BMW i3 is about to get a lot cooler. No, wait, a lot warmer. That's because there will a few new standard features in the i3 plug-in vehicles sold in the US, including seat heaters and satellite radio. Oh, and DC fast charging. The department head of BMW i USA, Jacob Harb, told BMW Blog that the company is, "now confident enough that in 2015 we will have the right infrastructure for DC fast charging, so it makes to include it standard in the MY2015." We can expect more details at the Detroit Auto Show in January and Harb told BMW Blog that, "you will be pleasantly surprised" by the announcement. There are a few other potential changes in store for the i3, including a configurable keyfob (like European i3 drivers get) and a heated steering wheel. It's unlikely that a sunroof or Lane Departure Warning will be offered, but Harb said BMW is always open to suggestions.

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 X5 gets full battery of performance visuals

If you think BMW toned down its third-generation X5 CUV a little too much with its latest redesign, the new M Performance Parts line of optional parts may give you a chance to inject in a new sense of style.
The aesthetic parts include new carbon fiber pieces for the mirror caps, front splitter, rear diffuser and rear aero flaps. There's also a rear spoiler, high-gloss black kidney grilles, M Performance rocker panel decals and double-spoke 21-inch wheels with performance tires. The interior upgrades are similar with an available Alcantara steering wheel with carbon fiber trim, stainless steel pedals and carbon fiber gearshift trim.
Not all of the M Performance Parts are about style. The M Performance Power Kit sharpens throttle response and boosts power of the X5 xDrive35i to 320 horsepower and 332 pound-feet of torque, an improvement of 20 hp and 32 lb-ft, and an optional exhaust with chrome tips improves its sound. For buyers looking for improved stopping power, the M Performance Brake Kit adds six-piston calipers with 19-inch steel rotors.
