2016 Chevy Camaro Convertible gets cleaner looks, improved refinement [UPDATE]

UPDATE: We have live photos from the reveal. Scroll to the bottom of the story and check them out in the Related Gallery. Back in May, Chevrolet introduced a redesigned Camaro. Now, and not at all surprisingly, the Bowtie brand is showing off the latest Camaro convertible, based on the coupe that debuted on Belle Isle in Detroit. From the beltline down, this is the same car that was so well-received last month. But above the waist, there's an all-new, fully automatic canvas roof that can be raised and lowered at speeds up to 30 miles per hour. On top of that, owners will be able to drop the roof remotely by simply pressing a button on the key. Chevy does not, however, say if this new convertible roof is lighter than last year's top. The biggest change for the Camaro convertible, though, is something we've long yearned for – a proper hard tonneau cover that deploys over the folded roof. The current muscle car's roof fabric has the unpleasant tendency to flap in the breeze. The new droptop shouldn't have that problem, and will likely boast an even cleaner top-down profile to boot. Like the hardtop, though, the Camaro convertible does benefit from the same lightweight structure, that helps trim "at least" 200 pounds of body fat. It should also make use of the same powertrain lineup, with a turbocharged four-cylinder, a 3.6-liter V6, and a 6.2-liter V8 with six-speed manuals or eight-speed automatic transmissions spanning the lineup. "From the beginning, the Camaro's architecture was developed to incorporate a convertible with uncompromised driving dynamics," Camaro chief engineer Al Oppenheiser said in the attached release. "Customers will appreciate what they don't feel: quivers, cowl shake or an under-damped chassis typically found in a four-seat convertible." Increased refinement, a cleaner look, better driving dynamics and a more usable convertible roof? We're looking forward to you 2016 Camaro convertible. Chevy claims the new car arrives in "early 2016," which means we should plan on seeing this droptop at the typically cold and snowy Detroit Auto Show. Until then, check out the full press release from Chevrolet.

Mopar Hellephant is sold out, but here are 4 other awesome crate V8s to try

Despite a relatively enormous $30,000 price tag, Mopar's 1,000-horsepower supercharged Hellephant crate engine sold out in just 48 hours. Some enthusiasts may have missed out on the crazy engine due to lack of funds, or they just assumed there would still be some Hellephants down the line. But worry not, swap-happy gearheads. There are plenty of V8s in the world to pick from, and we highlighted four favorites. They're not as powerful, but they're all cheaper, and still have a lot to offer. Mopar 6.2L Hellcrate Odds are a lot of prospective Hellephant buyers were Mopar fans to begin with, so we'll start the list with the next-most-potent offering: the Hellcrate. This is the same supercharged 6.2-liter V8 found under the hood of the Dodge Charger and Challenger Hellcats and the Grand Cherokee Trackhawk. It makes 707 horsepower and 650 pound-feet of torque like those cars, too. It's also about $10,000 cheaper than the Hellephant engine at $20,020, and that leftover money can be used to finish the project or for aftermarket upgrades to get it closer to the Hellephant's output. GM LS9 6.2L The Hellcrate isn't the only factory supercharged crate engine on the market. From General Motors comes the supercharged 6.2-liter LS9 V8. This is the engine that was used in the C6 Corvette ZR1. At 638 horsepower and 604 pound-feet of torque, it doesn't make as much power or torque as the Hellcrate. But it does boast a dry sump oil system. So instead of pumping oil out of a pan at the bottom, the engine uses an oil tank mounted remotely that pumps oil into the engine. This means the engine is shorter overall, and can be mounted lower for a better center of gravity. It also means that there's almost no risk of running the engine dry in hard cornering, as could happen with a normal oil sump where the oil can slosh to the side without the oil pump. Basically, it offers some major benefits if you want supercharged V8 power for a road course car. It's also a tad cheaper than the Hellcrate at $18,149. But get one while you can, because GM is only selling what's left from when it was building the C6 ZR1. Ford Aluminator 5.2XS Our pick from the Blue Oval lacks a supercharger, but it's still pretty sweet.

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.
