Detroit—If Audi's latest concept, Project Steppenwolf, comes to fruition, you'll be able to schlep farther afield in a smaller quattro-technology vehicle. The four-position, adjustable height air-suspension system found on the production allroad quattro has been given greater heights on this compact-class vehicle—a maximum ground clearance of 8.8 inches (0.6 inch higher), which can be lowered by 2.4 inches for reducing air drag at highway speeds.
The air suspension has an automatic and a manual mode. With automatic height setting, speed governs the height selected—at speeds of 50 and 80 mph, the system lowers the body in two 0.8-inch increments to the lowest level. The highest level, 0.8 inch above normal, must be selected manually, and returns to the normal position if speed exceeds 20 mph. The other levels can be manually fixed, provided no safety-critical speeds are exceeded.
New technology on the Steppenwolf includes an electronically activated parking brake. When the driver pushes a button, an 80-bar hydraulic pump clamps the rear brake calipers. A non-return valve blocks the return flow, locking the brakes. Pushing the button again restores normal foot-brake action. But unlike the ability to use a conventional hand brake as an emergency brake, the Audi system is only enabled when the ignition is on and the vehicle stopped. Perhaps, for some drivers' peace of mind, an intermediate setting would be incorporated if the system reaches production.
Now if we can only figure out if the vehicle was named for the book or the rock group?

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
