Camo'd Chevy Camaro ZL1 is one bad boy

Thanks to a fresh gallery of spy shots, we're getting a much better look at the next Chevrolet Camaro ZL1 during its development, and this machine is looking seriously mean. Unlike the last photos, the heavy cladding is gone from the body this time and is replaced by a camouflage wrap. That switch makes checking out the details a whole lot easier. The first thing you'll notice at the front is the massive grille that looks ready to devour anything that gets in the way. To add a little more menace, the lower air dam appears to jut out a bit more, as well. While harder to see in these latest shots, our spies say the hood still boasts an extractor similar to what's found on the Cadillac CTS-V. The big, double spoke wheels look great in black and really dominate the styling in profile. Look past them, and you notice some tweaked side sills, as well. At the very back, you can also spot some styling adjustments to the rear bumper. There's an unmissable wing back there, too. The powerplant for the ZL1 is still a mystery, but it's rumored to use the LT4 6.2-liter supercharged V8. The similar hood design as the CTS-V is one piece of evidence to support that. Even with the same engine, Chevy's engineers could tweak the output higher or lower than the Caddy. The wait to find out isn't too long because the ZL1 is anticipated to launch for the 2017 model year. Related Video:

2018 Hyundai Accent vs subcompact sedans: How it compares on paper

Hyundai first revealed the new 2018 Hyundai Accent a few months ago, but that debut was in Canada for the Canadian-market car. We didn't get our look at the U.S. version until just recently, which is when we also finally got plenty of specifications on the little car. So as we did with the Genesis G70, we've brought you a breakdown of the Accent's specs and some of the segment's best and most popular: the Nissan Versa, Kia Rio, Chevrolet Sonic and Toyota Yaris iA. Before we get to the chart, let's give you a quick reintroduction to the 2018 Accent. The subcompact is completely new this year, and under the hood is again a naturally aspirated 1.6-liter four-cylinder engine. It makes 7 fewer horsepower and 4 fewer pound-feet of torque than the outgoing model with totals of 130 horsepower and 119 pound-feet. This drop in power probably won't be noticeable, though. It's also available with either a manual or automatic transmission, both featuring six speeds. Fuel economy hasn't been announced, but the Rio's numbers below are probably a good indicator as they share powertrains. The one thing that isn't available with an Accent is a hatchback. According to Autoweek, the hatchback was canned with the assumption that hatch buyers would simply purchase an example of the upcoming Kona crossover. But if you want a traditional subcompact hatch from South Korea, Kia is happy to oblige, as the Rio is still available as a hatchback. Learning that the Kona may have killed the Accent hatch causes us to wonder if Kia brought the Rio hatch to the U.S. because it wasn't planning on offering the Stonic.

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.
