Sunday Drive: A tale of old favorites and upcoming challengers

Sedans and crossovers dominated the attention of our readers last week, led by the completely redesigned 2018 Honda Accord. It's the Japanese automaker's flagship, and people are seriously interested in finding out how good the latest Accord is. So interested, in fact, that no other single story came close to the brand-new Accord in Autoblog reader interest. Moving down the list we find the equally new 2018 Buick Enclave. The three-row crossover has a lot to offer a family, especially one looking for a nice, quiet ride. If you're looking for the exact opposite of nice and quiet, but still want enough room for you and your significant others, the Subaru WRX that we tested last week may be the perfect ride for you. Or, if you just want to drive fast and aren't at all worried about space, there's the Camaro SS. See? We offer something for everybody. From there, we look to the future. Who isn't interested in seeing the first fully electric vehicle from Porsche? And who isn't intrigued to see the Mission E testing alongside a gaggle of Teslas? A brand-new Jeep is always a big deal, especially when it's the revival of a classic nameplate like the Grand Wagoneer. And finally, we have something completely different: the Rezvani Tank. As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2018 Honda Accord First Drive | Feels like home again 2018 Buick Enclave First Drive Review | Fortress of quietude 2018 Subaru WRX Drivers' Notes | Turbo traditionalist 2018 Chevy Camaro SS Drivers' Notes | Demonstrative power, middling interior Porsche Mission E caught testing against Teslas Jeep three-row SUV caught on public roads — Grand Wagoneer, perhaps?

GM plans new car family for global markets, $5B investment

Globalization remains all the rage in the auto industry, as manufacturers scramble to develop single vehicles that can easily be adapted to the world's disparate market places. Ford has been a champion of this movement, with its One Ford mandate, but now, its cross-town rival is getting in on the action, albeit on a smaller scale. General Motors has announced a $5-billion investment to develop a new Chevrolet-badged family vehicle for global growth markets, including Brazil, Mexico, India, and importantly, China. With the PRC listed as a target market for the new vehicle, it's no surprise that GM is teaming with its Chinese joint-venture partner, SAIC Motor, to develop the vehicle's architecture and engines. The first vehicles should be hitting dealers by 2019, with GM expecting to eventually move some two million units per year. "With a significant majority of anticipated automotive industry growth in 2015 to 2030 outside of mature markets, Chevrolet is taking steps to capitalize on that growth," GM President Dan Ammann said in the attached statement. "Strengthening Chevrolet's position through this major investment is consistent with our global strategy to ensure long-term profitable growth in the markets where we operate." GM is quite focused on developing markets for a new vehicle, going as far as to say that "mature markets" like the US aren't currently being considered for the new family vehicle. As for where it will be built, the press release specifically says it won't be exported to the US, meaning it will very likely be built abroad using parts from local suppliers. Read on for the official press release from General Motors. Chevrolet Strengthens Position in Growth Markets with $5 Billion Investment 2015-07-28 All-new vehicle family tailored to local customer requirements General Motors and SAIC Motor partnership further enhanced DETROIT – Chevrolet announced today it is investing $5 billion to strengthen its business in global growth markets through the development of an all-new vehicle family that will meet the rapidly changing demands of customers in these markets. "With a significant majority of anticipated automotive industry growth in 2015 to 2030 outside of mature markets, Chevrolet is taking steps to capitalize on that growth," said General Motors President Dan Ammann.

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.
