manifoldNo doubt, there are computer technology in automobile designs. But the most important technology believe it or not is weight reduction. from aluminum engines to plastic body parts and thin metal sheets to hold everything in place. Even thin wall low profile tires made handling better, And struts are better to handle the light weight of these tires(no dead weight bounce0. But other technology made 1 million mile reliability a possible reality. Unfortunately material tend to oxidize and fail. And antifreeze may have to be changed every five years. Or else, the manifold gasket will leak($1000 repair bill). Even automatic transmission is cooled. That's how important antifreeze is. and has to be watched out for reliability. If you want to restore some 10-12 year old car, you have to change the antifreeze for five year intervals. This id the minimum you have to do for driver level restoration to continue 70,000 mile service free period. Light weight design of these year 2000 cars made octane 89 gasoline give out more torgue and thus save gas going up hill on highways. There could be 4 miles per gallon improvement on MPG figures.
