2015 BMW X3 arrives with tweaked styling, diesel option

The luxury crossover market has been a huge success for BMW, having sold over a million X3 models worldwide since the CUV first went on sale in 2003, not to mention all of the momentum its had with the larger X5. At the Chicago Auto Show, BMW is unveiling the refreshed 2015 X3, featuring an improved design, a new diesel engine option, and a rear-wheel drive variant.
The X3 is getting some handsome upgrades to the exterior. The twin, circular headlights now extend to touch the slightly widened, chrome kidney grille, to bring the styling in line with the 3 Series and 4 Series. (LED headlights are now optional, as well.) The front bumper gets reshaped brake cooling ducts, and the rear bumper gets a touch of additional metal trim at the bottom. BMW has also added standard LED turn signals in the side mirrors.
BMW has enhanced the interior with added chrome trim, high-gloss black trim around the center console, sliding covers for the cup holders and new interior upholstery designs. The X3 is also getting a major boost in optional technology - there's a new Parking Assistant, as well as an Active Driving Assistant with adaptive cruise control, Lane Departure Warning, Frontal Collision Warning, Pedestrian Warning, and City Collision Mitigation.

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.

Apple Watch watches your BMW i3, i8

Apple unveiled details about its long-awaited Apple Watch yesterday and we now know that the $349, er, watch will be released to the public early next year. Amid the millions of features the watch has is the ability to provide real-time information on the battery charge level in a BMW i3 or i8 plug-in vehicle. The watches can also help locate the vehicles if, say, they're parked in a crowded lot. Because so many of us lose our Bimmers on a daily basis. BMW spokesman Dave Buchko confirmed the integration of the Bimmer-centric features on Apple Watch to AutoblogGreen, and noted that the product will let users monitor heating and air-conditioning as well as remotely unlocking the car. "This latest device has the potential to change how owners interact with their BMW, paving the way for a new level of personalization and immediacy," Buchko said. The new wrist-based connection allows for a nice bit of exposure for the German company's new i series. As of the end of last month, BMW had sold 2,082 i3 battery-electric vehicles in the US since starting domestic sales in May. It also sold nine of i8 plug-in hybrids in August, the first partial month for US sales.
