Here are the best-selling cars and trucks from January 2015

Every month, Autoblog slogs through all the sales figures reported by automakers that do business in the United States, and, after a little bit of sorting, we put it into an easy-to-read chart in an attempt to make it as easy as possible to follow the ins and outs of sales and shipments. But that only covers the brands themselves, not the individual models they sell. And we think you'd all be interested in knowing which vehicles beat their rivals in sales from month to month, so we've put together this handy gallery to keep you in the know. While the leader of the pack may not come as much of a surprise, the order that the top ten finishes in changes frequently – due to automaker deals, the price of gas, etc. – and we've included some statistics to help you see how their current performance stacks up to month's past.

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.

OnStar to offer 90-day driving assessment, possible insurance discount

General Motors has announced a brace of new features for OnStar, two of which could help you save money assuming you're willing to sign over some (more) personal details. The first is a driving assessment program in which OnStar takes note of certain driving parameters for 90 days, then provides the driver feedback on their driving, both individually and when compared to other drivers in the program, as well as driving tips. Think of it as OnStar's ICE version of the Nissan Leaf's CARWING feature that compares how efficient your electric driving is compared to other BEV drivers. In this case, though, certain drivers will have the chance to share their assessment with Progressive Insurance, and if the numbers are right they might get a "driving-based" discount from the insurance company. The assessment program is voluntary, and requires opting in. It will be available this summer on all new GM cars and some GM vehicles back to 2013. In case this sounds like Big Brother, let's not forget that Big Brother is already here and moved in so long ago that he's a member of the Kiwanis club and is hosting neighborhood block parties. Progressive already has a million enrollees in a program called Snapshot that tracks OBD II data to offer usage-based insurance to provide annual pricing based on how much you drive your car, with discounts of up to 30 percent. The OnStar effort is just another way to do that. The second feature is proximity offers through AtYourService, which notifies drivers to deals and information on their driving route and provides coupons from RetailMeNot and Entertainment Book. Beyond that, a deal with Priceline will let OnStar agents book hotels for you starting this year, there's a tie-in with Dunkin' Donuts, too, but we're fuzzy on those benefits, and third new feature lets Chevrolet owners know when certain parts need replacing.
