positive post of the day mazda to add lightness

Brace yourself ladies and gentlemen, because an automaker is taking on one of the American market’s greatest bugbears: size and weight bloat. Mazda’s vehicles have gained 80 pounds on average with each recent redesign, according to Robert Davis, senior vice president of product development and quality for Mazda North American Operations. Davis tells Automotive News [sub] that increases are coming “mostly in larger tires and wheels, and safety equipment,” resulting in a 2010 Mazda3 that weighs 2,868 pounds compared to a 2003 Protege’s 2,634 pounds. And, says Davis, that’s all about to change. He promises “typical” weight reductions of 220 pounds per vehicle on future Mazda models, through a combination of measures. For one thing, dimensional creep is a thing of the past, with some Mazda models scheduled to lose as much as three inches in length.

Improved packaging should help reduce the impact on interior feel, while the use of more light-weight materials should also help decrease overall mass and weight. Though Davis does warn that “carbon-fiber roofs and hoods are great for a BMW M5, but they are not viable in our cost structure.” The weight reduction will not only improve fuel economy between three and five percent, it will also allow the use of more efficient engines without losing Mazda’s trademark sporty feel. And, frankly, it will provide a wonderful example to automakers like Honda who built their brands on light-weight, fun-to-drive cars before succumbing to dimensional and weight bloat over the past decade. Weight is not only the enemy of efficiency, it’s also the enemy of fun. If Mazda is serious about differentiating its vehicles with lower weights (and efficiency numbers on the last two generations of Mazda3s indicate that it probably should), this could possibly just herald a new trend that’s been a long time coming to the US market. Setting concrete goals like a 220 pound average reduction per vehicle is just the kind of challenge to the industry we’ve been looking for.

Kudos to Mazda. Of all the cars I've owned over the past quarter-century, a lowly 2,200-pound Civic Si still stands out as one of my favourites. The closer we can get to that standard while still meeting safety regulations, the better.

This is great and all, and I do love Mazda's...the problem is that most of their top-sellers have had a recent refresh so how long are we gonna have to wait to see the results. That's assuming they'll be good to their word. And where's the Mazda2?

  The US spec of the Mazda 2 will be at the LA Auto show. It's going to be a 2011 model year car, and will probably be released next autumn. But you're right, the Mazda 3 and 6 were redesigned for MY2009 and 2010. The 2 started with MY2008 I believe. It will be a while before we see any results.

Philip I love seeing these stories regarding concepts that I have vague memories of from collector magazines, books, etc (usually by the esteemed Richard Langworth who I credit for most of my car history knowledge!!!). On a tangent here, I remember reading Lee Iacocca's autobiography in the late 1980s, and being impressed, though on a second reading, my older and self realized why Henry Ford II must have found him irritating. He took credit for and boasted about everything successful being his alone, and sidestepped anything that was unsuccessful. Although a very interesting about some of the history of the US car industry from the 1950s through the 1980s, one needs to remind oneself of the subjective recounting in this book. Iacocca mentioned Henry II's motto "Never complain; never explain" which is basically the M.O. of the Royal Family, so few heard his side of the story. I first began to question Iacocca's rationale when he calls himself "The Father of the Mustang". He even said how so many people have taken credit for the Mustang that he would hate to be seen in public with the mother. To me, much of the Mustang's success needs to be credited to the DESIGNER Joe Oros. If the car did not have that iconic appearance, it wouldn't have become an icon. Of course accounting (making it affordable), marketing (identifying and understanding the car's market) and engineering (building a car from a Falcon base to meet the cost and marketing goals) were also instrumental, as well as Iacocca's leadership....but truth be told, I don't give him much credit at all. If he did it all, it would have looked as dowdy as a 1980s K-car. He simply did not grasp car style and design like a Bill Mitchell or John Delorean at GM. Hell, in the same book he claims credit for the Brougham era four-door Thunderbird with landau bars (ugh) and putting a "Rolls-Royce grille" on the Continental Mark III. Interesting ideas, but made the cars look chintzy, old-fashioned and pretentious. Dean Martin found them cool as "Matt Helm" in the late 1960s, but he was already well into middle age by then. It's hard not to laugh at these cartoon vehicles.
Dwford The real crime is not bringing this EV to the US (along with the Jeep Avenger EV)
Kwik_Shift_Pro4X Another Hyunkia'sis? 🙈
SCE to AUX "Hyundai told us that perhaps he or she is a performance enthusiast who is EV hesitant."I'm not so sure. If you're 'EV hesitant', you're not going to jump into a $66k performance car for your first EV experience, especially with its compromised range. Unless this car is purchased as a weekend toy, which perhaps Hyundai is describing.Quite the opposite, I think this car is for a 2nd-time EV buyer (like me*) who understands what they're getting into. Even the Model 3 Performance is a less overt track star.*But since I have no interest in owning a performance car, this one wouldn't be for me. A heavily-discounted standard Ioniq 5 (or 6) would be fine.Tim - When you say the car is longer and wider, is that achieved with cladding changes, or metal (like the Raptor)?
