Toyota Supra, Rolls-Royces, dozens of BMWs recalled for backup camera issue

Weeks after Nissan and Infiniti recalled more than 1.2 million vehicles for a potentially dangerous programming oversight in the backup camera settings, BMW has issued a recall for similar problems. The recall, which covers 257,481 vehicles, includes numerous BMWs, as well as two Rolls-Royce models, and the 2020 Toyota Supra.  In total, the recall potentially affects 51 different products. This includes the 2018 BMW 540D, 2018–2019 BMW 640I, Rolls-Royce Phantom, 2018–2020 BMW 530e, 530i, 540i, M5, M550i, X3, 2019 Rolls-Royce Cullinan, 2019–2020 BMW 330I, 740Le, 740Li, 745Le, 750Li, 840i, M340i, M850i, X4, X5, X6, X7, Z4, and 2020 Toyota Supra. On certain BMW models, xDrive variants are also included. According to NHTSA campaign No. 19V684000, "The back-up camera and display settings can be adjusted such that the rearview image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse." If there is no display image when backing up, drivers can't properly see, and the car no longer meets modern safety regulations. Specifically, Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rearview Mirrors."  The recall was filed on September 27, 2019, and BMW plans to begin notifying affected owners in November. BMW, Toyota, and Rolls-Royce dealers will update the vehicles' software, which should fix the problem. 

BMW shuffles chairs in its design department

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.
