The use of lighter and lighter automobiles and heavier and heavier trucks also make the imbalance between the proportion of assignable damage compared to income even worse when it comes to being a subsidy of trucking.
Mr. Harris, on this issue I argue. Cars are NOT getting lighter. They are getting bigger and heavier. As for instance, the Mercedes-Benz 190E, when introduced, weighed in at 2800 lbs, 104" wheel base, 174" total length, 67" wide, 52" tall, with a 2.3 litre 4-cylinder producing 110 bhp. Today's equivalent car is the Mercedes C300, which weighs 3560 lbs, 108" wheelbase, 182" long, 69 wide, 56 high. And it commonly comes with the 4Matic AWD system these days, which adds another 300 lbs to that weight. It remains a car generally inadequate for transporting 4 passengers, either way.
But... that's just one model, right? Wrong. Some more:
Honda Accord:
1990: 2733 lbs, WB 107, Length 182, Width 67, Height 54
2010: 3605 lbs, WB 110, Length 195, Width 72, Height 58
Diff: + 872 lbs, WB +3", Length +13", Width +5", Height +4"
Ford Taurus:
1985: 3050lbs, WB 106, Length 188, Width 70", Height 54"
2010: 3930lbs, WB 113, Length 203, Width 76, Height 61"
Diff: +880lbs, WB +7", Length +15", Width +6", Height +7".
BMW 5-series:
1981: 3020lbs, WB 104", Length 182", Width 66, Height 56
2012: 4034lbs, WB 117, Length 192", Width 73", Height 58
Diff: +1014lb, WB +13", Length +10, Width 7", Height +2"
And just to make the argument that people are downsizing invalid,
1990 Honda Accord:
2733 lbs, WB 107, Length 182, Width 67, Height 54
2011 Honda Civic:
2831 lbs, WB 107, Length 177, Width 69, Height 56"
So... the 2011 Honda Civic is about the same size- a tad shorter in overall length, taller and wider- than the 1990 Honda Accord... and it weighs about 100 lbs more, to boot.
And just to make for some interesting comparing...
1973 Honda Civic:
1500lbs, WB 86, Length 139", Width 59", Height 52"
+1331lbs, WB +21", Length 38", Width +10", Height +4".
So compared to the Honda Civic of 1973, todays car is almost double the weight, nearly 2 feet longer in wheelbase, nearly 3 feet longer in overall length, almost a foot wider, and 4 inches taller.
So in my opinion, "downsizing" is us just getting back to sensible sizes that were present 20 years ago, if that. And either way, cars ain't getting lighter. Oh, lighter gauge metal, most assuredly. But what we take away from the weight of quality, we put back twofold in the weight of gimcrackery.
