Why Are Vehicles Still so Heavy? Blame Manufacturing Infrastructure

Car manufacturers have achieved significant fuel economy gains in recent years, but the improvements largely come down to upgraded drivetrain efficiency. Vehicles still weigh substantially more today than they did in the early 1980s, when the previous decade’s demand for fuel economy improvements forced the issue.

Since then, automobiles have gradually packed on the pounds — negatively offsetting the technology encouraging fuel frugality. Modern safety concerns, improved build quality, sound dampening, and consumer demand for bigness have all helped to keep the typical family transport oinking around a two-ton curb weight.

If companies could effectively slim down those autos, without sacrificing structural rigidity, safety, or consumer comfort, the efficiency gains would become all the more significant. However, with few consumers ready to dive back into noisy, frail hatchbacks, weight savings will likely need to be done on the molecular level. In a new study, the Center for Automotive Research (CAR) in Ann Arbor investigated the materials going into 44 separate 2015 model year cars and asked automakers what would they use if they suddenly needed to reduce weight from essential items.

GM Will Set Base Curb Weight For Its Truck Lineup

Review: 2014 Jeep Grand Cherokee Summit (Video)

I got a call from my folks a year ago. It went something like this: “your mom wants a new Grand Cherokee for her birthday, what do you think?” I called up Chrysler and snagged a 2013 Grand Cherokee Overland Summit, the last major Mercedes/Chrysler vehicle to launch before Fiat took the reins. I came to the conclusion the American Range Rover was all kinds of crazy, had drivetrain deficiencies and she should wait until the 2014 refresh. That refresh has landed, so should mom buy one?

Review: 2013 Cadillac ATS

Smaller grille than CTS, but clearly a Cadillac.

Size and weight are a big part of GM’s DNA. They beat Ford not with a frontal assault on the Model T but by offering a larger, heavier, flashier car. They thought they could do the same to BMW. But, even as the Bavarians packed on the inches and pounds, car buyers “in the know” saw the additional size and weight of Cadillacs as a sign that the General either lacked technical competence or just didn’t “get it.” Well, maybe the “new GM” really is different. With the 2013 Cadillac ATS, the company has pulled out all the stops to directly challenge the BMW 3-Series with a rear-wheel-drive car that is—surprise—a few tenths of an inch smaller and a few pounds lighter. Could the people who tried to sell us the Cimmaron have gotten this one right?

  • Slavuta So, Trump was hyperbolic... big deal.
  • Slavuta The question was, "does it make sense for Elon...?" I don't know why people jumped into conclusions in this comment section. My answer is this - if he does it, it makes sense to him. He knows better than any of us here. May be with his donations he can become an ambassador to an important state or secretary of energy, or chief of NASA. This is how America works. Donate $1m - ambassador to Poland, $3m - japan, $5M - Germany, etc. $20,000 could buy you Kenya or something
  • CanadaCraig We should be able to give comments a 'dislike' or 'thumbs down'. We're not 6 years old. I'm sure we cope if someone doesn't 'like' our comment.
  • Dartdude He knows that a Trump economy is a great opportunity to sell more cars (EV,ICE). Compare both terms and Trumps is the winner by a long shot.
  • Michael S6 Somewhat shocking that Tesla has maintained its sky high stock valuation. The faithful continue to have unshakeable faith in Musk. Tesla models are in dire need of redesign to be competitive although the model 3 recently got a refresh. I test drove a model S six months ago and it's was very nice driving car. However, the interior was very underwhelming in quality of materials and design. There is absence of physical controls such as a turning stalk, and the rear seat was uncomfortable. Tesla would have been in much better shape if they redesigned its current models to face the competition, rather than spending so much money creating a Cybertruck.
