Recharge Wrap-up: Long Beach ePrix, London's new electric buses

London will put 51 new electric buses into service. With the addition of these buses, two more routes (in addition to one already in operation) will be all-electric. Transport for London plans to have all of central London's 300 single-decker buses running on electricity or hydrogen by 2020. "The expansion of London's electric bus fleet demonstrates our commitment to reducing emissions from public transport in London," says Deputy Mayor of London for Environment and Energy, Matthew Pencharz. "The Ultra Low Emission Zone that will be introduced in 2020 is the most ambitious measure of its kind taken to tackle air pollution anywhere in the world, and it will transform our bus fleet into a cleaner, greener and more pleasant way of travelling for Londoners."

Along with 10 Cruze vehicles, one 2015 Volt has been recalled because of a tie rod that might not have been tightened to the steering gear correctly, which could lead to a loss of steering control. Chevrolet will replace the steering gear assembly, supplied by Robert Bosch Automotive Steering, for free. There have been no reported injuries from this issue. Read more at Detroit News. The Formula E Long Beach ePrix will take place on April 2, 2016. For the second season of the electric racing series, Long Beach is the only confirmed US host, as the spot on the calendar previously held by Miami still remains to be determined. More than 20,000 fans attended the inaugural Long Beach ePrix earlier this year, where Nelson Piquet, Jr. took first place before going on to win the Drivers' Championship. "It's extremely exciting to welcome the ePrix back to Long Beach for a second year," says Long Beach Mayor Robert Garcia, "and we are hopeful that this demonstration of innovation, sustainability, and cutting edge technology will return to our city year after year."

The FIA (Federation Internationale de l'Automobile) World Motor Sport Council recently approved the calendar for the second season of the FIA Formula E Championship, with Long Beach scheduled as the sixth of 11 rounds in the series. Overall, 10 venues will host Formula E events, with the 2015-16 season beginning once again in Beijing on Oct. 17.

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.

GM might lose 90-year U.S. sales crown over chip shortage

Automotive News editor Nick Bunkley tweeted on October 1 that according to AutoNews data, General Motors "has been the largest seller of vehicles in the U.S. every year since passing Ford in 1931." With automakers having turned in light car and truck sales data for the first three quarters of 2021, GM's 90-year-run might not reach 91. According to AN figures, Toyota was 80,401 vehicles ahead when the October workday started. Worse, GM is so far behind its historic pace that it might only sell enough light vehicles in the U.S. to match its numbers from 1958.  Meanwhile, the New York Times put a few more salient numbers to the pain GM and Toyota are enduring alongside the the rest of the industry. GM sold 33% fewer cars in Q3 2021 than it did in Q3 2019 during the dark days of the pandemic, 446,997 units this year as opposed to 665,192 last year. GM's Q3 2020 was only down 13% on Q3 2019. Over at Toyota, the bottom line showed a 1% gain in Q3 2021 compared to 2020, with 566,005 units moved off dealer lots. The finer numbers show two steps forward and one step back, though; Toyota's September sales were down 22% compared to last year.  GM remains optimistic about what's ahead, GM's president of North American operations telling the NYT, "We look forward to a more stable operating environment through the fall." We'd like to see that happen, but we don't know how it happens. The chip shortage said to have been the inciting incident for the current woes isn't over, and not only can no one agree when it will be over, the automakers, chip producers, and U.S. government still can't get on the same page about who needs what and when. Looking away from that for a second shows articles about "No End In Sight" for supply chain disruptions in early September, before China had to start working through power supply constraints, global supply chain workers started warning of a "system collapse," and roughly 500,000 containers sat waiting to be unloaded at Southern California ports — a record number seemingly broken every week. And back to chips, we're told just a few days ago the chip shortage is "worse than we thought."   For now, the NYT wrote that GM dealer inventory is down 40% from June to roughly 129,000 vehicles, and down 84% from the days when dealers would cumulatively keep about 800,000 light vehicles in stock. However, GM just announced it would have almost all of its U.S. facilities back online next week, although some would run at partial capacity.
