I just ordered a new Focus ST, pretty much the only way to get the zero-option set up I wanted. Can’t wait for it to arrive. The car’s not here yet, but the questions are. This time, a wheel & tire question for your consideration.
While we don’t get a massive amount of snow here in Southern Illinois, we do get some. I’ve learned the hard way that relatively wide, low profile summer tires and all-seasons are bad news in the winter. I’m ready to go the winter tire route, so I wanted to get your thoughts on wheel choices for winter tires in a minus-1 size. (Read More…)
Protean Electric In-Wheel Electric Motor
It’s April, when automotive engineers from all over the world gather in Detroit for the SAE World Congress. Protean Electric, which has been promoting the electrification of cars with their in-wheel mounted direct drive motors for the past few years, used the occasion of the World Congress to introduce the production version of their motor, which will start being assembled in a Protean owned factory in China next year.
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.
Sajeev, what ever happened to 14-inch wheels? I mean, seriously, does the Caliber really need to be shod with 17-inchers? Why does my dad’s new half-ton pickup have 17-inch wheels? His old one had what used to be the industry standard 235-75R15. He about had a coronary when he found out new tires would be over $100 each. Perhaps if I put on my tinfoil hat, I’d say the tire companies are behind this. So really, does the average family sedan or minivan really need anything bigger that a 15-inch wheel/tire?
