Bmw M3 Coupe 2-door on 2040-cars

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.

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 recalls 6,073 units of i3 and Minis to replace airbag

BMW is replacing the passenger's side front airbag module on 6,073 vehicles in the US because of a supplier's manufacturing issue with the part. The affected models include the: 2014-2015 i3; 2014-2016 Mini Hardtop 2 Door Cooper and Cooper S; 2015-2016 Hardtop 2 Door John Cooper Works; and 2015-2016 Hardtop 4 Door Cooper and Cooper S. Because the airbag components aren't made correctly, they might not deploy with enough restraint in a low-speed collision. BMW isn't aware of any accidents or injuries from the problem, but this is still obviously a safety concern. According to company spokesperson David Buchko to Autoblog, customers will be notified about the issue by mail in November. As always, dealers will perform the replacements at no cost to owners.

Due to a manufacturing error, the passenger frontal air bag may not deploy properly in a low speed crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection." CONSEQUENCE: In the event of a vehicle crash, an air bag that does not deploy properly increases the risk of injury to the front seat passenger. REMEDY: MINI and BMW will notify owners, and dealers will replace the passenger frontal air bag module, free of charge. The recall is expected to begin on November 20, 2015. Owners may contact MINI customer service at 1-866-825-1525 and BMW customer service at 1-800-525-7417. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. BMW Statement: BMW has informed NHTSA of its intention to voluntarily recall approximately 923 BMW i3 vehicles to replace the passenger-side front airbag module.
