Can a car be lifted using rubber bands?

It's quite amazing what it takes to lift a car. We already know the feat can be accomplished using just a pair of phone books, but what about rubber bands? To the Internet! A video series appropriately titled "Will It Lift" attempted to find out by using a massive crane and a Nissan Micra weighing less than 1,800 pounds.
Doing a little math, the trio determined that it would take 180 rubber bands to support the car. A metal bar was placed through the window openings and another was place atop the car, and then attached together using the rubber bands and hooked to the crane. Now these aren't any special rubber bands or anything. They're just eight-millimeters thick, but the stunt is testing the rubber bands' power in numbers.
We're not going to spoil it for you, so scroll down to check out the video of the stunt.

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.

Weekly Recap: Volkswagen moves forward under Muller

Most stunning was the speed of it all. On the morning of September 18, Volkswagen AG stood atop the automotive world. It was profitable and sold more cars than Toyota and General Motors, its two main rivals for global supremacy. By nightfall, the company would be embroiled in scandal. Revelations the German auto giant cheated on diesel emissions testing in the United States reverberated from Washington to Wolfsburg, Germany. What started out as a problem with 482,000 VWs and Audis in the US exploded into an international scandal. Millions of vehicles have the rigged software, meaning VW broke environmental rules as its cars spewed pollutants all over the world. The fallout began immediately. Volkswagen CEO Martin Winterkorn – one of the most respected and capable executives in the business – apologized on Sunday and Tuesday. On Wednesday he resigned. As the week progressed, the company's stock took a beating and credit agencies threatened to drop their ratings. VW dealers and owners said they felt betrayed. The automaker hired a law firm that defended BP after the Deepwater Horizon oil spill. The EPA is already extending its testing procedures to look for "defeat devices" like the ones used by Volkswagen. On Friday the company announced a major restructuring. Matthias Muller, Porsche's chief for the last five years, took over as CEO of Volkswagen and is charged with picking up the pieces of a shattered company facing regulatory action and lawsuits. With GM, Toyota, and Takata scandals still fresh, Volkswagen will likely experience unprecedented levels of scrutiny. Additionally, VW's markets in the United States, Canada, and Mexico will be combined into a North American region under the leadership of former Skoda boss Winfried Vahland, though US chief executive Michael Horn will stay on. The company is also realigning its brands by specialty and streamlining its board. Firings, government action, restructurings, and international outrage – things that usually build up over months or years – all occurred in about a week. With dizzying speed, Volkswagen's future has changed dramatically. It all happened, it's still happening, so fast.
