Weekly Recap: Electric Rapide concept showcases Aston's future

Aston Martin showed off an all-electric Rapide S prototype this week and announced an agreement with investment firm ChinaEquity to explore development of a production version of the sports sedan. The car could arrive in about two years if the project advances, and it would be built in Gaydon, England. The concept car, called the "RapidE" was developed with Williams Advanced Engineering. The electric Rapide is meant to highlight British innovation, and it was revealed during a state visit by Chinese president Xi Jinping to the United Kingdom. Spec were not available for the concept on display. "The car we showed in London is a fully running concept but not yet defining [of] our choice of battery, motor, inverter, etc," spokesman Simon Sproule said. "Now that we have a clearer path for producing the car, we will be defining all the parameters." Aston Martin has been vocal about its electric ambitions this year, and Sproule told us at the New York Auto Show that an all-electric Rapide could cost $200,000 to $250,000 or more. "It's a study, but we're serious about it," he said. Some reports have indicated the electric Rapide could pack as much as 1,000 horsepower. Aston considers electric technology the strongest play for modernizing its powertrains and meeting emissions standards around the world. Hybrids and all-electric models can offer high outputs and strong torque delivery, which is in keeping with the Aston's image as a sportscar maker. Company brass prefer this option over dropping down to four-cylinder engines. And yes, V8s and V12s remain part of the plan. The electric push is part of Aston's future strategy to remake its lineup, which includes refreshing its sportscars, building a production version of the electric all-wheel-drive DBX concept shown at the Geneva Motor Show, and adding a four-door Lagonda. OTHER NEWS & NOTES Domino's serves up purpose-built delivery car Domino's revealed a purpose-built pizza delivery car based on the Chevy Spark. It's called the DXP, for Delivery Expert, and it can handle up to 80 pizzas. The pies stay warm thanks to an oven located behind the driver's seat, and the DXP is sauced up with a puddle-lighting feature that projects the Domino's logo outside of the car. Power comes from the Spark's stock 1.2-liter four-cylinder engine rated at 84 hp that gets up to 39 mpg on the highway. Chevy dealers will be trained to service the DXP.

2014 Chevrolet Corvette Stingray Convertible gives us a couple of looks

Put away your pixel paintbrushes, kids. Pack up your Photoshop. This is the real-deal 2014 Chevrolet Corvette Stingray Convertible in its first official images. The droptop Chevrolet will roll into the bright lights of the Palexpo exhibition at next week's Geneva Motor Show, a four-wheeled statement of intent that General Motors is serious about taking its Corvette franchise global.
Chevy isn't providing anything in the way of further details with these two shots, but we've learned at least a couple of things about the car shown here. First off, the example seen in these images is fitted with the optional Z51 Performance Package - something that isn't immediately evident because there's no sign of the coupe model's prominent ductwork on its rear haunches. In order to accommodate the power folding hard tonneau cover, the vents that feed the transmission and differential coolers have been relocated to the underside of the car. The dark paint color on this example also does a good job of muting the contrasting black front fender vents and hood opening - Z51-spec design details that have proven to be somewhat controversial.
One other thing to note: These two shots also display the Stingray wearing different alloy wheels than the split five-spoke design shown at the hardtop's Detroit Auto Show unveiling in January. The simpler, thin five-spoke wheels should do a good job of showing off the Z51's upgraded brakes, and they'll be optional on the coupe as well.

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.
