BMW offers xDrive on 2015 2 Series

BMW has released its mile-long list of model changes for 2015. It's mostly comprised of tiny tweaks to options packages, pricing or trim colors, but there are a few interesting new features in there too. One thing all buyers will notice is that as of July 1, the company's destination charge increases by $25, to $950 for all of its models.
The 2 Series gets two really useful upgrades for 2015. We already knew that BMW's xDrive all-wheel drive system would be offered on the M235i this summer. However, it won't be the only 2 capable of spinning all four wheels. The 228i model will also be available with the system for $34,850 (after destination), $1,800 more than the standard model.
The other big addition brings a sportier ride to the 228i (with or without xDrive) for those who don't want to spring for the M235i. BMW is adding a Track Handling Package (pictured above) that lowers the suspension 10mm and includes the Adaptive M Suspension, Variable Sport Steering, M Sport Brakes and 18-inch wheels with Michelin Pilot Super Sport tires. It's available on manual or automatic models at $1,600 for cars ordered with the M Sport or Sport Line trims or $2,200 without it.

Watch the BMW i8 get wrung out on the Ring

Been wondering where the heck the reviews of the all-new, plug-in-hybrid BMW i8 have been? After all, the car isn't exactly new, having debuted in concept form way back in September of 2009. In August of last year, we even tested a prototype of the new supercar. Despite that, though, we still haven't gotten a crack at the actual vehicle that will be sold to the public.
Well, we're happy to tell you that we're currently testing the i8 and will have a proper review for you soon. If, however, you're just aching for some coverage of the low-slung plug-in, we have a short video of it in action around Germany's famed Nürburgring.
Despite it's three-cylinder, turbocharged gas engine, the i8 sounds pretty angry as it laps the Ring. That is, until it has a little bit of a breakdown. According to the guys that caught the car on video, it appeared the i8 had a minor brake issue, and was parked on the side of the track for a good 15 minutes, with the driver pumping the brakes. We should probably just take this as proof, then, that manufacturers are actually using the Ring for testing, and not just messing about.

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.
