2015 Ford Mustang Convertible makes inappropriate appearance in Detroit [w/video]

With the polar vortex fresh in the minds of Autoblog's Detroit-based staff, we're finding it funny that any manufacturer would choose January in the Motor City to show off a new and highly anticipated convertible to the general media and public for the first time. But Ford has done just that, giving us our first real peek at the new Mustang Convertible in the flesh.
The new Mustang Convertible is more or less unchanged from the standard coupe, with some subtle styling tweaks to accommodate the retractable soft top. Engine and transmission choices are identical to the hardtop, although we should expect slightly lower performance due to the hardware for the roof. Like the coupe, neither prices nor performance metrics have been published yet for the convertible.

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.

Mercedes-Benz Sprinter and Ford Transit can haul on the track

Line up any two comparable vehicles, and eople are going to want to race them. Need proof? In its latest track battle, Auto Express wants to know which commercial vehicle can lap a circuit faster - a Ford Transit or Mercedes-Benz Sprinter. Let's face it, neither of these European vans were ever meant to be near the track unless they are delivering a racecar and a ton of parts for a fun weekend, but it's massively fun to watch them give it a go anyway.
The one thing that Auto Express really illustrates here is the modern marvel that is stability control. The driver hops curves, and these big vans lean in the corners like your friend walking home from a long night at the bar. However, because of the amazing stability systems, the vans mostly keep all of their wheels planted and never seem close to getting sloppy, despite their behemoth size.
Unfortunately, the two vans aren't exactly fairly paired. The Ford has a dual rear axle and a few other advantages over the Mercedes, but it's still hilarious to watch them go. Even better, the host breaks down everything happening behind the wheel like these commercial vehicles were two Porsches. Enjoy watching this very unorthodox battle between Ford and Mercedes.
