Recharge Wrap-up: Panasonic, Tesla on Gigafactory deal?

Bentley has been awarded the Carbon Trust Standard for reductions of carbon, water use and waste production in manufacturing. The Carbon Trust is an organization that helps groups such as businesses and governments reduce carbon emissions, use of energy and resources, and waste output. From 2011 to 2013, Bentley reduced CO2 emissions by 16 percent per car manufactured, curtailed water use by 35.7 percent, and saw significant waste reductions. Darran Messem of Carbon trust says, "Bentley is clearly passionate about continuing to improve its environmental performance, which is reflected by the fact the company has consistently invested in new technology."

The organization will use the range-extended electric cars in its efforts to help MBA students learn from and work with small business owners. As part of the MBAs Across America program's first year, four students drove 8,000 miles to provide entrepreneurs with free business counseling. The program has expanded, and this year, teams of MBAs will use the Volts to travel to 25 cities to offer their services. Learn more about the partnership between Chevrolet and MBAs Across America in the press release below. A professor from the University of Michigan has found fuel cycle analysis to be too flawed to be relied upon for measuring CO2 impacts of transportation fuels. Professor John DeCicco of the university's Energy Institute feels that the flaws in calculating the carbon footprint of liquid fuel production and combustion make such lifecycle analysis impractical. He suggests, instead, to focus to carbon capture. Since capturing CO2 directly from a vehicle is probably never going to happen, DiCicco believes the solution is to capture carbon from the atmosphere in sectors outside of transportation. Says DiCicco, "Research should be ramped up on options for increasing the rate at which CO2 is removed from the atmosphere and on programs to manage and utilize carbon fixed in the biosphere, which offers the best CO2 removal mechanism now at hand. Such strategies can complement measures that control the demand for liquid fuels by reducing travel activity, improving vehicle efficiency and shifting to non-carbon fuels."

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.

Dodge Challenger outsold Mustang, Camaro in third quarter of 2019

The Dodge Challenger is nearly old enough to start driver's ed in some states, and it doesn't have a firm grasp on the increasingly crucial concept of downsizing, yet it beat the odds to become the most popular American two-door model during the third quarter of 2019. Its ballooning sales figures suggest buyers don't always want the latest, most advanced car they can get their hands on. Dodge sold 18,031 examples of the Challenger during the third quarter of 2019, a shocking 21% increase over the same period in 2018. It's a true muscle car, normally sardined in the same can as the Chevrolet Camaro and the Ford Mustang, a pair of smaller, nimbler two-doors that are much closer to the historic definition of a pony car. Semantics aside, the Mustang finished on the second spot of the sales podium with 16,823 sales, a 12.3% drop compared to the third quarter of 2018, and the Camaro took third with 12,275 sales, a 15% dip that alarmingly comes in the wake of two redesigns. More specific sales figures aren't available. We don't know what percentage of the sales mix V8s represent, or whether buyers prefer manual or automatic transmissions. The scoreboard looks different when we examine 2019's year-to-date figures. The Mustang takes first place with 55,365 sales, followed by the Challenger at 46,699, and the Camaro at 36,791. While the Challenger's recent ascent is encouraging, it can't mask the fact that two-door models no longer enjoy a favorable tailwind, and the entire segment — not just the American entries — is declining. The aforementioned year-to-date figures are down by 10.1, 11, and 7.6 percent, respectively. The third-quarter statistics revealed a handful of other surprises unrelated to the world of performance. Dodge notably sold three examples of the Dart, a sedan it hasn't built since 2016. That's a 93% drop compared to the 45 units that found a home during the third quarter of 2018.
