Ringbrothers drops more hints about its wild SEMA creations

Ringbrothers isn't finished teasing its SEMA creations. First we got a sliver of rear quarter on a 1969 Chevrolet Camaro that revealed a bundle of carbon fiber and SEMA-obligatory deep-dish wheels. The Wisconsin tuner's now announced its litter of cars headed to the show and a few specs, along with two shadowy drawings. The Camaro, christened with the name Valkyrja and a two-tone paint job, gets stretched in two directions with severe fender flares to widen the body and an extended wheelbase. We're not sure what's happening with the Camaro's snout in the drawing, but under that bulging hood we'll find a 416-cubic-inch LS V8 from Wegner Motorsports. Wegner built the 416-cu-in supercharged LS3 V8 that powered Ringbrothers' 1,000-hp G-Code Camaro in 2016.  The second member of the gang is a 1969 Ford Mustang Mach 1 dubbed Unkl. The exterior begs for attention with a deep blue sea paint job, deep front chin spoiler, bulging hood, yellow brake calipers, and what looks like a racing number inside a roundel on the doors. Unkl gets its motivation from a 520-cu-in Boss V8 built by Kaase Racing Engines, rumored to throw about 800 hp.    Finally, Ringbrothers is bringing its Cadillac Madam V for another Las Vegas go-round after giving the custom coupe some updates. The Madam V is a 1948 Cadillac Series 62 fastback coupe body placed atop an ATS-V chassis, first shown in 2016. The firm didn't elaborate on the changes, so all we can expect for now are the coupe's postwar good looks mixed with new-millennium engineering, and a 3.6-liter twin-turbo V6 with 464 hp under that exceptionally long hood.    For any in attendance at the show, the Valkyrja Camaro debuts at the BASF booth on Tuesday, Nov. 5, 2019 at 9:30 a.m., the Unkl Mustang gets revealed a couple hours later at the Flowmaster/Holley booth, and the Madam V Cadillac will be on display throughout the show at the Ringbrothers booth.

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.

2016 Chevy Volt rated at 106 MPGe, 53 miles of pure EV range

Following a string of rumors, Chevrolet and the Environmental Protection Agency have released official fuel economy numbers for the second-generation Volt. As was reported earlier today, the new and improved hybrid will cover 53 miles on pure electric power. As Chevy tells it, first-gen Volt owners cover about 80 percent of their mileage on EV power alone, so the 40-percent increase from the second-gen should lead to an even bigger reduction in gas-powered Volt mileage. Chevy expects some 90 percent of mileage to come from a plug with its new 2016 model. This newfound EV range comes thanks to the 2016 Volt's 18.4-kilowatt hour lithium-ion battery. Rated at 106 MPGe by the feds – exactly what was promised by a June leak – the 2016 Volt improves nicely on the current model's 17.1-kWh, 98-MPGe battery back. There's also a marked improvement when relying on the gas-powered on-board generator. The 1.5-liter, four-cylinder engine will happily run on regular fuel and return a still-impressive 42 miles per gallon combined rating once the battery's state of charge is depleted. Expect the freeway to cruise to be even better, although Chevy isn't ready to say by how much. Fully charged and with a full tank, drivers should expect to cover 420 miles, a 40-mile improvement over the current model. Scroll down for the official press release from Chevrolet Related Video: The Results Are In: More Range for the 2016 Volt EPA-estimated pure electric range is 53 miles DETROIT – The 2016 Volt is engineered to offer customers more of what they want: range, range and more range. The Volt's all-new second-generation Voltec extended range electric propulsion system delivers 53 miles of pure EV range, based on EPA testing. That is nearly a 40-percent improvement over the first generation Volt. Chevrolet expects many next-generation Volt owners will use power solely from their battery for more than 90 percent of trips. Today, Volt owners use battery power on 80 percent of their trips. This means that the average Volt owner may expect to travel well over 1,000 miles between gas fill ups, if they charge regularly. For the first 53 miles, the Volt can drive gas and tailpipe-emissions free using a full charge of electricity stored in its new 18.4-kWh lithium-ion battery, which is rated at a combined 106 MPGe, or gasoline equivalent. When the Volt's battery runs low, a gas-powered generator seamlessly operates to extend the driving range for a total of 420 miles on a full tank.
