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.

Recharge Wrap-up: Tesla P85D upgrades coming soon, lease a Chevy Volt for $149 a month

CarCharging has raised $6 million from shareholders and has restructured to save cash. The EV charging company plans to expand further in 2015 - with an eye toward achieving profitability - in part by investing in technology and "unlocking the value of our significant equipment inventory," says CarCharging CEO Michael D. Farkas. The group expects to reduce administrative costs by 40 percent, and has hired an interim Chief Financial Officer to help carry out its plans for growth. CarCharging raised the cash through offering convertible preferred stock to its shareholders, whom Farkas thanked "for their passion and patience." Read more in the press release below.

GM’s move to Woodward is the right one — for the company and for Detroit

Back in 2018, Chevy invited me to attend the Detroit Auto Show on the company dime to get an early preview of the then-newly redesigned Silverado. The trip involved a stay at the Renaissance Center — just a quick People Mover ride from the show. IÂ’d been visiting Detroit in January for nearly a decade, and not once had I set foot inside General MotorsÂ’ glass-sided headquarters. I was intrigued, to say the least. Thinking back on my time in the buildings that GM will leave behind when it departs for the new Hudson's site on Woodward Avenue, two things struck me. For one, its hotel rooms are cold in January. Sure, itÂ’s glass towers designed in the 1960s and '70s; I calibrated my expectations accordingly. But when I could only barely see out of the place for all the ice forming on the inside of the glass, it drove home just how flawed this iconic structure is.  My second and more pertinent observation was that the RenCen doesnÂ’t really feel like itÂ’s in a city at all, much less one as populous as Detroit. The complex is effectively severed from its surroundings by swirling ribbons of both river and asphalt. To the west sits the Windsor tunnel entrance; to the east, parking lots for nearly as far as the eye can see. To its north is the massive Jefferson Avenue and to its south, the Detroit River. You get the sense that if Henry Ford II and his team of investors had gotten their way, the whole thing would have been built offshore with the swirling channel doubling as a moat. This isnÂ’t a building the draws the city in; itÂ’s one designed to keep it out. Frost on the inside of the RenCen hotel glass. Contrasted with the new Hudson's project GM intends to move into, a mixed-use anchor with residential, office, retail and entertainment offerings smack-dab in Detroit's most vibrant district, the RenCen is a symbol of an era when each office in DetroitÂ’s downtown was an island in a rising sea of dilapidation. Back then, those who fortified against the rapid erosion of DetroitÂ’s urban bedrock stood the best chance of surviving. This was the era that brought us ugly skyways and eventually the People Mover — anything to help suburban commuters keep their metaphorical feet dry. The RenCen offered — and still offers — virtually any necessity and plenty of nice-to-haves, all accessible without ever venturing outside, especially in the winter, but those enticements are geared to those who trek in from suburbia to toil in its hallways.
