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.

Leopard walks in, shuts down a Mercedes-Benz plant

In recent months the auto industry has seen plant closures due to a host of reasons — parts shortages, recalls, natural disasters, and even a once-in-a-lifetime pandemic. Now it can add to that list the threat of an invading leopard. A Mercedes-Benz factory in Pune, India, was forced to halt production for a few hours when a wayward jungle cat wandered into the facility, When the 3-year-old male leopard was spotted inside the manufacturing unit of the factory, it caused a panic among workers, according to a release by rescue organization Wildlife SOS discovered by The Drive. The site was shut down for about six hours as a Wildlife SOS rapid response team from the Manikdoh Leopard Rescue Centre and the State Forest Department safely removed the curious cat.

The team's veterinary officers Dr. Nikhil Bangar and Dr. Shubham Patil carried out the rescue operation, tranquilizing the feline and loading it into a wildlife carrier. The rescue took about four hours, and Wildlife SOS reports that neither the creature nor any workers sustained injuries. The leopard was released back into the wild.  No one is quite sure how it got onto the factory grounds, but Wildlife SOS says that the forests in the surrounding region have one of the highest densities of leopards in the world. It's also suffering from rapid deforestation. That encroachment by humans has led to a decrease in the leopard's natural prey as well, so wildlife experts think it may have been looking for food.  The Mercedes plant builds the Maybach S 560, S-Class, E-Class Long Wheelbase, C-Class, CLA, GLA, GLE and GLS for the Indian market.  We have a different theory. We believe that the cat was seeking to set the record straight with Mercedes. When the S 65 AMG debuted, Mercedes claimed it featured the world's first Road Surface Scan technology to detect pavement undulations and adjust suspension damping accordingly. The only problem with that claim: Nissan had the technology some 30 years earlier in several mid-80s models, including the Maxima and Japan's version of the Infiniti M30, which was called — you guessed it — the Leopard. 

Recharge Wrap-up: Formula E's other events, continued record EV sales

Formula E wants fans to know that it is more than just a race. During each ePrix weekend, the electric race series hosts a variety of events. For each race, Formula E sets up an eVillage where fans can meet drivers and get autographs, learn about electric vehicles, spectate Formula E's School Series races, enjoy live music and dance performances, play games, eat food and take part in numerous other activities that don't make their way into the television broadcast. Or course, though, the race is always the main event. See more in the video above. Electric vehicles enjoyed a fourth straight month of record sales in February. Despite low oil prices, customers bought an estimated 7,881 EVs last month, up 13 percent from a year before. 52 percent of those sales were battery electric vehicles, while the rest were plug-in hybrids. BMW i3 sales dropped 77 percent over a year ago, selling 248 cars. The Tesla Model S and Chevrolet Volt sold the most, while the Ford Fusion Energi outsold the Nissan Leaf for the first time. The Audi A3 E-Tron sold 248 units (same as the BMW i3) despite low inventory. Read more at Inside EVs. Renault more than doubled its EV sales in January compared to a year before. Sales were up 104 percent, at 1,886 units (1,977 if you include the Twizy). This January marked higher EV sales for Renault than the three previous years. The biggest selling Renault EV, which also happened to be Europe's best selling EV, was the Renault Zoe, up 105 percent at 1,416 units sold. Read more at Inside EVs. Nissan's "No Charge to Charge" promotion has expanded to Orlando, Florida. This is the 27th market in the US to offer free charging to Nissan Leaf customers. Buyers and lessees get two years of free charging with an EZ-Charge card, which works with AeroVironment, Blink, ChargePoint, Greenlots and NRG eVgo charging networks. "Significantly lower operating costs and a fun-to-drive nature make owning the all-electric Leaf a cost-effective and convenient choice for Orlando residents," says Nissan EV Sales & Marketing Director Andrew Speaker.
