Conquest and controversy conclude the 2014 Rolex 24 at Daytona [spoilers]

If you don't wish to know who won the 2014 Rolex 24 at Daytona, you should avert your eyes right now. We'll even give you a double-space to skedaddle...
For those of you still with us, the first race in the United SportsCar Championship (USCC) is done, but the discussions about it certainly won't end for a while. Daytona Prototypes claimed the first four overall places, the top spot taken by the No. 5 Action Express Coyote-Chevrolet Corvette DP driven by Joao Barbosa, Christian Fittipaldi, Sebastien Bourdain and Burt Friselle. The 16th and final caution of the race bunched the field up for an eight-minute sprint to the flag, so the first place getter finished just 1.4 seconds ahead of the No. 10 Wayne Taylor Racing Dallara-Chevrolet Corvette DP driven by Max Angelelli. Third place went to Brian Friselle in the No. 9 Action Express Chevrolet Corvette DP, 20 seconds down. Chevrolet power hasn't taken the overall win since 2003, eleven years later it scores a one-two-three-four. The No. 6 Muscle Milk/Pickett Racing ORECA-Nissan 03 scored fifth place, the top LMP2 finisher.
The Prototype Challenge class win went to the No. 54 CORE Autosport team of Colin Braun, Jon Bennett, Mark Wilkins and James Gue.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.

Chevy previews 2016 Malibu ahead of New York debut

With everything going on in Geneva this week, it would be all-too easy to forget that there's still stuff going on back home in America. And the upcoming new Chevy Malibu is a prime example. Chevrolet has announced that it is bringing an all-new Malibu to the New York Auto Show next month, teasing us with this preview image and a few enticing details. For starters, when we say it's all new, this time we mean it's all new. The next-generation Malibu has been built on a new platform that uses more high-strength steel to cut 300 pounds off the curb weight compared to the outgoing model. It's also got a wheelbase that's almost four inches longer, with shorter overhangs front and rear and a roofline that tapers stylishly and more gradually towards the tail. We'll have to wait a little longer – but not too much longer – to find out more, but in the meantime you can read what Chevy's telling us so far in the press release below. Born Again: Next-Gen Chevrolet Malibu Announced Larger, lighter and more efficient Malibu to be unveiled at New York Auto Show 2015-03-04 DETROIT – Designed to deliver more efficiency, connectivity and advanced safety features than ever, the next-generation 2016 Chevrolet Malibu will make its public debut at the New York International Auto Show this April. Using a blank slate approach, Chevrolet designers benefited from an entirely new architecture, which for Malibu includes a wheelbase nearly four inches longer than the outgoing model. That, in turn, provides increased rear legroom and interior space. Due to a higher-strength steel structure, the new Malibu is also expected to be 300 pounds lighter than the current model, which benefits the sedan's fuel economy and handling. "Malibu's gorgeous styling is the result of a masterful understanding of proportions," said Ed Welburn, General Motors' vice president of Global Design. "The roofline has been stretched rearward giving a more sleek profile, while the front wheels have moved forward and front and rear overhangs have been reduced. Along with the sculpted body side, these cues help Malibu appear more dynamic and sophisticated." More details about the 2016 Chevrolet Malibu will be shared each week leading up to the vehicle's global debut. The 2016 Malibu is expected to go on sale by the end of 2015. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 115 countries and selling around 4.8 million cars and trucks a year.
