Hehe. I've always liked the Brabham insane-in-the-membrane turbo fan car:
Those were the days... Got a slow car? STRAP A TURBOFAN TO THE BACK! Part of that fugly era when ground-effect was king and cars looked like aviation parts with a guy in a tupperware crash-helmet strapped in the middle:
All in all, the cars don't look too bad these days even with the aero surfaces sticking up all over the place.
Does anyone else think that the cost-cutting and stringent design rules have actually hampered competition? The rules have meant that the essence of an F1 car is identical (indeed, mandated) between all the teams. So only teams with tens of millions to spend on testing and tweaking the rigid design within the rules manage to eke out 9 tenths to turn a midfield car into a dominating one. Before the rules, a relatively poor team could negate their disadvantage by building some cheap but effective design elements or technology into their cars. I'm not advocating a return to the ground-effect era, rather saying that strict design rules alone won't bring competition. They've instead meant that making a car quicker than the others costs disproportionately more money.
