BMW working on DCT for its FWD cars?

Having introduced its first front-wheel drive products, a report in BMW Blog says that BMW is developing a dual-clutch transmission to use in some of those vehicles. If that is the case then BMW would be catching up to its competitors, with Mercedes-Benz using its 7G-DCT in models like the CLA, and Audi putting its six-speed S-tronic in the A3 and seven-speed S tronic in the A6. Acura and Hyundai use dual-clutch gearboxes in their model lineup as well. Right now the only self-shifting option in the front-wheel-drive-based BMW X1 is an Aisin-sourced eight-speed automatic, the one we described as "perfectly fine but not a standout" that requires "some prodding to coax a downshift." The eight-speed sport transmission will be an option in late 2016, but its paddle shifters and quicker gearchanges still won't be equal to a DCT. That latter possibility would give BMW a sportier avenue of development if it did wish to create something truly athletic out of the X1 – BMW Blog muses on an X1 M40i or an X1 M (you should be past the point of shock if this happens). The Mini range could also benefit, the JCW trims currently fitted with a six-speed sport automatic being obvious candidates. Assuming Munich engineers are on the case, it is predicted that we won't see this transmission for at least two years.

BMW Motorrad celebrates 90 years with new R nineT roadster [w/video]

90 years is a heck of a long time by any standard, and as good a cause for celebration as we've ever seen. That's how long BMW has been making motorcycles for, and it's celebrating with the retro cafe racer you see here - as promised and previewed.
Dubbed the R nineT (for 90 years), the latest product from BMW Motorrad traces its roots back to the original 1923 BMW R 32. And like the original, it's powered by a boxer twin - in this case, a 1,170cc air- and oil-cooled unit delivering 110 horsepower and 88 pound-feet of torque. All that muscle is packed into a classically-styled roadster that looks ready to line up next to a Moto Guzzi Griso, Triumph Thruxton or Ducati SportClassic.
The neo-retro styling drapes a unique tubular steel spaceframe chassis that uses the engine as a stressed member. The inverted telescopic front fork is borrowed from the S 1000 RR superbike and a paralever swingarm with spring strut suspends the rear. That's where you'll find a removable rear pillion for an extra passenger and dual tailpipes mounted on the left side, swappable for a titanium Akrapovic exhaust - just one of many customization options BMW Motorrad is offering for the R nineT.

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.
