Chevy EN-V 2.0 coming to Tianjin Eco-City in China

Chevrolet is bringing its EN-V 2.0 to the Sino-Singapore Tianjin Eco-City in China to show off the "Electric Networked-Vehicle" and demonstrate sustainable urban mobility. The small, two-seat EV concept is an updated version of the original EN-V, a vision of getting around in a future world where space is at a premium and clean air is a priority. So what better place to showcase the evolved EN-V than at the Tianjin Eco-City? The Eco-City is being developed as a planned urban space with eco-consciousness built in. The joint venture between China and Singapore offers an alternative to country living and smog-filled cities. Tianjin Eco-City, slated to be completed by 2020, will be able to offer 350,000 inhabitants clean air and water, renewable energy, green transportation and living spaces and, if all goes as planned, jobs for 50 percent of the residents. Currently, only about three square kilometers of the planned 30 square kilometers have been built, with only about 6,000 permanent residents, but there's still time. The EN-V 2.0, as the "Networked" part of its name suggests, not only features mobile internet, but can communicate with other cars around it. Along with GPS and built-in sensors, this connection between vehicles allows the car to drive autonomously (at least in theory - again, there's still time). This is ideal in an urban environment where congestion can be a major issue. The EN-V 2.0 improves upon the original concept with climate control, storage space and all-weather capability, which also make life more bearable and daily commuting possible. We first saw renderings of the updated vehicle in 2012. The Chevrolet EN-V 2.0 will be used in the Eco-City's National Animation Industry Park and Eco-Business Park of the course of the two-week demonstration. Read on below for more in the press release from GM. GM to Demonstrate Chevrolet EN-V 2.0 in Tianjin Eco-City SHANGHAI – General Motors today announced that it will begin demonstrating the Chevrolet EN-V 2.0 (Electric Networked-Vehicle) in the Sino-Singapore Tianjin Eco-City this week, signaling the company's learning and progress in sustainable urban mobility. The demonstration will help GM further understand consumers' usage of low-speed transportation tools for their daily commute. During the two-week demonstration period, the EN-V 2.0s will be used in the National Animation Industry Park and Eco-Business Park inside the Sino-Singapore Tianjin Eco-City.

2015 Chevy Spark will have lighter, smaller battery

As General Motors gets ready to release the 2015 Chevy Spark EV, it is retooling the Brownstown Battery Assembly to build a new battery system for the chirpy little electric car. The new Spark will lose a few pounds and kWh from its lithium-ion pack, but it will keep all of it's performance specs. The current Spark EV uses a 21-kWh lithium-ion battery pack with bits made by A123 Systems (known as B456 Systems during bankruptcy). For the 2015 model, GM is going to build a 19-kWh battery system in-house that will use 192 LG Chem cells. Losing a bit of energy capacity means that the battery system for the 2015 Spark EV will be 86 pounds lighter but it will keep the EPA-rated 82-mile range and 119 MPGe. The 2015 Spark EV also keeps its $26,685 (plus destination) starting price from the 2014 model. The car will once again qualify for a federal tax credit of up to $7,500. LG Chem also supplies the cells for GM's other plug-in vehicles from its facility in Western Michigan. The Brownstown production line currently builds the battery packs for the Chevy Volt, the Opel Ampera and the Cadillac ELR. You can read our first drive of the 2014 Chevy Spark here. Brownstown Battery Assembly Expands Capabilities Will build battery system for 2015 Chevrolet Spark EV 2014-05-14 DETROIT – General Motors will bring all its electric vehicle battery building capabilities in-house with production of battery systems for the 2015 Chevrolet Spark EV at its battery assembly plant in Brownstown, Mich. "Using our in-house engineering and manufacturing expertise enabled us to deliver a battery system that is more efficient and lighter than the 2014 Spark EV without sacrificing range," said Larry Nitz, executive director of GM global transmission and electrification engineering. "Our successful working relationship with LG Chem has allowed us to deliver a new battery system for the Spark EV that helps us to better leverage our economies of scale." A newly designed battery system features an overall storage capacity of 19 kWh and uses 192 lithium ion cells. The cells are produced at LG Chem's plant in Holland, Mich. The battery system weight of 474 lbs. is 86 pounds lighter than the system in the 2014 Spark EV. The Spark EV battery is built on a dedicated production line at Brownstown, which also manufactures complete battery packs for the Chevrolet Volt, Opel Ampera and Cadillac ELR.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
