Smart Car structure at NAIAS in 2011

2012 NAIAS rumored display of smaller cars, not what public wants or needs

With press review days a week away, rumors and auto web reports say the 2012 North American International Auto Show in Detroit will have a heavy focus on smaller cars. Question is, will the public be convinced to buy them?

From MarketWatch to Auto News and others, the reports also indicate the 2012 North American International Auto Show will be rife with claims of increased gas mileage, more use of electric motors and rechargeable batteries as trends. Nonetheless, this focus on smaller cars is misguided, in this reporter's opinion; and in the eyes of the public who are being deluged with offers of smaller cars, especially EVs, for more money than the masses can afford.

Fact is, present auto production processes do not lend themselves to building light, large cars. So, this reporter sees this shift to smaller cars, not as something the public wants, but more as a familiar ruse by the automakers to first show capabiity to meet MPG mandates, but also to buy time until they figure out how to revamp their manufacturing processes. Fact is, lighter cars are coming, but they making them smaller to rid th eweight is not progress.

Of course, the steel industry is on the side of automakers, touting the continuity of present processes, and the supposed safety of steel over lighter materials; but the facts say otherwise. Lighter is not necessarily weaker or less safe. Witness the body structure of the Tesla S sedan which meets all safety standards.

So, think smart body design here. Think structural design with lighter materials, even a combination of extruded aluminum welded to aluminum panels for greater structural integrity. Moving to aluminum, magnesium and carbon fiber, however, will require a major shift in manufacturing processes at auto plants. This will be as significant as the change from processing IC engines to electrification with lithium-ion batteries.
