So by your reasoning, every car will be bigger than the previous. GM have trucks made to tow stuff with. And as it said in the article the S10 is not competitive on the market.
Hav'nt you learned yet that bigger, better and faster isn't always the best or smartest path to take?
Smaller, cheaper, more efficient vehicles are the way to go. Some day the wasteful American ideal of "bigger is better" will fade.
Typically, new cars/trucks grow marginally on the outside and grow a little bit more inside from generation to generation.
'92 --> '97 --> '02 Camrys grew a bit bigger inside/outside with each generation and got more powerful engines as the generations progressed.
Inline-4 went from 125HP to 157HP and got better fuel economy
V6 went from 192HP to 210HP to 225HP and got better fuel economy with each upgrade.
Safety features of course inmproved with each generation as well as well as performance.
Similar trends (slightly larger size, better fuel economy, more powerful) can be seen with other cars (Corolla, Civic, Altima, Maxima), pickups (Ram, Silverado, Ram, Dakota), and SUV's (RX330, Explorer, Trailblazer, etc.).
In fact, the new Colorado/Canyon are now MID-SIZE vehicles which puts it in the company with the Dodge Dakota. So these new trucks have managed to get significantly larger and less capable during 10 years of "advancement"
Heck, my dad's V6 powered Frontier even manages to pull 5,000 lbs vs 4,000 lbs for these "new" trucks.
