Stock Miata beats bunch of high-powered cars in wet 1/4-mile drag race

When is a stock, 167-horsepower Mazda MX-5 Miata quicker than a Chevrolet Corvette, Ford Mustang, Lamborghini Gallardo, Lotus Elise and a Porsche 911? When it's raining. Sort of.
Mazda Canada arranged a unique drag race to show off the fact that the Miata's optional power retractable folding hardtop can go from top-down to top-up in just 12 seconds flat. In this video, all six cars line up for a drag race, and it starts to rain (well, sort of - but you'll have to watch the video all the way to the end to see what we mean). The green flag is waved, and the timer starts as soon as the convertibles begin to put their tops up. But because the Miata's roof mechanism gets the car's roof back up a full 5.1 seconds quicker than the second-place car, the Mazda gets a serious advantage off the line for the actual drag race.
It's a fun video. And while we've spoiled the results (come on, the video was uploaded by Mazda, you knew the Miata was going to win), be sure to see how it all unfolds, below.

70% of pickups could use aluminum by 2025

In the next decade, the auto industry will see an explosion in its use of aluminum to cut weight and increase fuel economy, according to a study from market analysts Ducker Worldwide cited by The Detroit News. We are already seeing the lightweight metal show up extensively in luxury models from Europe, but with the impending launch of aluminum-intensive 2015 Ford F-150 (pictured above), North America is using it even more, as well. The report predicts 70 percent of US pickups to have aluminum bodies by 2025.
It won't just be pickups that see the benefit, though. The average amount of aluminum in US vehicles is forecasted by the study to grow from an average of 350 pounds in 2013 to about 550 pounds by 2025. The most common parts to use it will be hoods, doors and - to some extent - roofs, as well.
The massive increase in pickups' aluminum content hardly seems surprising. The F-150 is predicted to use so much that it might cause a short-term shortage, according to one earlier report. At the same time General Motors is heavily rumored to be negotiating with suppliers for the next generation Chevrolet Silverado and GMC Sierra. Ram is the last holdout of the Big Three, but the study predicts that not to last.
