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.

7 major automakers to build open EV charging network

A new joint venture established by BMW, GM, Honda, Hyundai, Kia, Mercedes-Benz and Stellantis will build a new North American electric vehicle charging network on a scale designed to compete with Tesla's industry-benchmark Supercharger network. The 30,000-plus planned new chargers will accommodate both Tesla's almost-standard North American Charging System (NACS) and existing automakers' Combined Charging System (CCS) options, effectively guaranteeing compatibility with the vast majority of current and upcoming electric models — whether they're from one of the involved automakers or not.  "With the generational investments in public charging being implemented on the Federal and State level, the joint venture will leverage public and private funds to accelerate the installation of high-powered charging for customers. The new charging stations will be accessible to all battery-powered electric vehicles from any automaker using Combined Charging System (CCS) or North American Charging Standard (NACS) and are expected to meet or exceed the spirit and requirements of the U.S. National Electric Vehicle Infrastructure (NEVI) program." Critically, the automakers involved will have a say in how the charging tech is implemented, guaranteeing that the hardware will play nicely with each automaker's in-house charging systems. Hyundai and Kia, for example, were hesitant to jump on board the Tesla NACS bandwagon earlier this year over concerns that the Supercharger network is insufficient for powering the two automakers' 800-volt charging systems; similar tech is used by Volkswagen and Porsche.  In addition to providing much-needed capacity and high-output charging for America's growing fleet of electric cars and trucks, the new network will integrate seamlessly with each automaker's in-app and in-vehicle features, rather than forcing customers to use third-party tools and payment systems, as is the case with some existing public charging infrastructure.  "The functions and services of the network will allow for seamless integration with participating automakersÂ’ in-vehicle and in-app experiences, including reservations, intelligent route planning and navigation, payment applications, transparent energy management and more. In addition, the network will leverage Plug & Charge technology to further enhance the customer experience," the announcement said.

2016 Chevrolet Camaro: Everything we know so far [UPDATE]

UPDATE: We fully expect the floodgates to open as facts and photos leak throughout the day. Watch this space for more information as it breaks, including these leaked photos, and some new powertrain speculation. Chevrolet has made a grand production of teasing the all-new, sixth-generation Camaro. That slow trickle will become a deluge this weekend, when the 2016 model hits the stage on Detroit's Belle Isle as part of an all-day Camaro-palooza. Considering you're likely to hear plenty about the next-gen muscle car in the next couple days, we figured now is the perfect time to sort out all the facts and rumors we've heard about the next-generation coupe that's coming this weekend. Here's everything we know about Camaro Six. What Will It Look Like? Arguably the easiest Camaro question to answer after all the teasers and spy shots, General Motors' design team favored evolving the current car's retro design language while retaining the same basic shape. The long hood will carry on, joined by an even shorter, wing-topped rear deck, giving the 2016 an almost fastback-like look. The greenhouse is still slim, but lateral visibility may improve slightly owing to the larger quarter windows. We can only hope. The rear end looks to have been rounded, while Chevy's own teaser shows off larger, more prominent taillight housings than the simple rectangular lights on today's car. Expect quad-tipped exhausts to be offered on at least one version of the Camaro. Judging by the single teaser of the car's profile, the rear haunches will be larger and more chiseled. The muscular aluminum hood and its accompanying power bulge are more heavily styled than on today's car, although it looks largely similar in terms of size. It sits atop an even slimmer upper grille that's barely big enough for Chevy's Bowtie logo, with most of the visual mass moving to the gaping lower grille. One of the more tantalizing rumors surrounding the new Camaro focuses on its roof. As evidenced in a rather bizarre round of spy photos, it almost looks like Chevy is considering a removable panel, a la Corvette Stingray. T-tops are also a distinct (and more probable, we hope) possibility. The new shape will result in a more aerodynamic car, and Chevy claims the 2016 Camaro spent 350 hours in the wind tunnel. Overall lift has apparently been cut by 30 percent, thanks partially to a new, smooth underbody panel. Chevrolet has been far less forthcoming with information on the new Camaro's cabin.
