GM Hy-wire

GM Hy-wire A vehicle that teeters high above customer demand—without a net.

We've driven the car of the future. It does not fly, it's not the drive itself, and it looks like the car instead of several machines such outrageous GM Motorama dream, finned wings, turbine-powered Firebirds of yore. This is serious, according to GM serious cash to invest ("hundreds of millions," they said) in a program that has produced 30-plus patent-to-date. The Hy-wire, which is displayed in the Paris auto show last fall, is the incarnation of a proof-of-concept that runs the concept of autonomy from 2002 Detroit show and thus offer a view of the future through the three portals.
First, there is the idea of ​​a high-value, long-lasting, "skateboard" chassis fully integrated walking, the various bodies can moor. Furthermore, there is a system of control drive-by-wire. And finally, there is a hydrogen fuel-cell powertrain. These concepts will likely arrive one at a time on a different vehicle, but the crystal-ball people at GM have integrated them here.
Skateboard concept promises to offer low Corvettelike gravity for better handling and unlimited flexibility in packaging bodywork. A high concentration of investment mechanical chassis with the age of 20 years allowed the body to be a high-fashion item of income in the form confined by boundaries far less functional. Drive-by-wire allows the driver to sit on the right or left, feeling control can be adjusted to the driver's taste or mood, and it is an enabler for technology such as automated highways. And hydrogen-powered fuel cell, which only emits water, promised to keep the car from the debate and partly to protect the auto industry from unexpected fluctuations in the oil industry (most hydrogen is produced from natural gas in the country). That's a lot of hope packed into one 4200-pound concept car.
Snap-on body Hy-wire offers an environment, luxurious roomy for five with an open area of ​​the front seat to the back of the nose and the tail. It attaches via the installation of 10 points (plus one electrical connector) to the all-aluminum, control-arm-suspended rolling chassis that is 11 inches thick. This package of 94-kW cell fuel, which attract hydrogen from the three 5000-psi compressed-hydrogen tank to power the 80-hp electric motor driving the front wheels. The tanks hold 4.4 pounds of hydrogen (containing the energy equivalent of two gallons of gas) for a range of 80 miles. Motors in each wheel and 10,000-psi tanks, but some improvements are expected to lead to a skateboard chassis with a six-inch-thick 170-mile range.
Hydrogen Today

    Fuel cells back nearly twice the efficiency of the best diesel engines of the energy in the fuel, but the total energy input factors upstream of the tank, and the advantages of hydrogen falling to as low as 10 percent.
    The current rate of production of hydrogen could power 15 percent of the transportation segment.

    Hydrogen is currently used: the production of ammonia, 51%, gasoline desulfurization, 45%, chemical manufacturing, 3%, other 1%.
No batteries onboard amplifier, so there is no regenerative braking. This is done partly to save weight and package space and also to illustrate that the fuel cell can generate enough electricity on demand. We are not entirely convinced of this argument. Step-off life, as in electric cars (peak torque at 0 rpm), but the Hy-wire seems to have some lag, especially when accelerating as if to pass. Order to speed up, and one can hear the air compressor and control valves various hydrogen clicking the whir of the motor drive. Acceleration is 10 seconds to 40 mph relaxed.

Swedish SKF company engineered a drive-by-wire Hy-wire system which uses much of the same hardware found in the concept Bertone Filo (Upfront, November 2001), but the software is greatly improved. Grip Two plays set up like an aircraft control yoke manage steering, braking, and acceleration. To accelerate, twist grip, knuckles back like on a motorcycle, press grips for braking, and steer them through a 20-degree angle to hang a U-ey
