HyFive hydrogen infrastructure gets $51M boost across Europe

"High five!" was one of the catch-phrases of Sacha Baron Cohen's Kazakh comedic alter ego Borat. A real-world HyFive is being announced by a power broker named Boris. And this is serious business. London Mayor Boris Johnson has announced a program called HyFive, which will see automakers and other entities invest 31 million British pounds ($51 million US) in a demonstration project for hydrogen fuel-cell vehicles. By next year, London will have three hydrogen refueling stations, while there will be one each in the Danish cities of Aarhus and Odense and one in Innsbruck, Austria. Leaders of the program are planning for other stations in Sweden, Germany and Italy. The five participating automakers are BMW, Mercedes-Benz parent Daimler, Honda, Hyundai and Toyota, while other companies involved include Copenhagen Hydrogen Network, ITM Power and Linde. Those OEMs will make 110 fuel-cell vehicles available for deployment in Bolzano, Copenhagen, Innsbruck, London, Munich and Stuttgart. The program represents an effort to address the "chicken or egg?" challenge inherent to establishing a hydrogen fuel cell vehicle market. While the powertrain technology provides benefits by combining fossil-fuel-like refueling times with long driving ranges and zero emissions, establishing a refueling network and building fuel-cell vehicles is prohibitively expensive, especially in low volumes. The London mayor is no stranger to green transportation technology. Late last year, Johnson made himself available for a photo opportunity with Ecotive and Frazer-Nash, which had developed a six-passenger extended-range plug-in taxicab. The mayor got a test drive in the cabs this week. You can check out the HyFive press release below. Global leaders sign up to GBP31m plan to demonstrate viability of hydrogen vehicles International project HyFive pioneers hydrogen fuel cell technology A pioneering GBP31 million deal will be struck today (3 April) to make hydrogen vehicles a viable and environmentally friendly choice for motorists across Europe. Leading motor manufacturers, hydrogen fuel suppliers, the Mayor of London's Office and energy consultancies from around the globe are signing up to the HyFive project, the largest of its kind in Europe, at City Hall in London today.

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.

BMW M3 driving off cliff is a chilling PSA

We're a little shocked that the unnamed owner of this cliff-diving E46 BMW M3 would upload the in-car footage of his accident to YouTube. Not only that, he uploaded two videos: raw footage of his roll down the cliff (it looks like somewhere in the Southwest, maybe Arizona) and a tribute video for his BMW that suffered the most severe consequences of understeer. Not only does uploading the videos leave him wide open for judgment by fellow enthusiasts (just read the YouTube comments), but we imagine if the police and his insurance company somehow don't know about the incident already, they will shortly. Scroll below to view for yourself.
The raw footage shows the sort of driving that led to the M3's violent tumble, and it serves as a good public service announcement reminder for everyone out there: Just like the Spengler's streams, double yellow lines aren't meant to be crossed. Also, hard driving is one thing, but hammering on public roads at speeds clearly above your skill levels as a driver is not only a recipe for legal trouble, it's a script for ruining your car at the very least, if not your life.
