This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Toyota Alphard and Vellfire JDM minivans look weirder than ever

Around these parts, if you want a Toyota minivan, you'll be looking at the Sienna. But in its domestic market, the Japanese automaker offers an entirely different line of passenger vans. And now it's updated one of its larger models. Or two, we should say. Since Toyota operates parallel dealership networks in Japan, the minivan you see here is sold as the Alphard through Toyopet dealers and the Vellfire in its Netz showrooms. They also get subtly different designs, especially at the front. But stylistic and distribution differences aside, these two models are essentially the same. They're smaller than the Sienna we know in every dimension but height, but larger than the Voxy/Noah and Esquire, and come in a variety of trims and configurations: with a 2.5-liter four, a 3.5-liter V6 or a hybrid powertrain, in seven- or eight-seat configurations, with or without handicapped accessibility, and in trim levels that can more than double their price from the base model to the top Executive Lounge. Initially launched in 2002 and redesigned for 2015, the new Alphard and Vellfire also benefit from a redesigned suspension, better NVH insulation and a more accommodating and upscale interior with new technologies (including a new Panoramic View Monitor, Intelligent Parking Assist and collision-avoidance systems) to make them more comfortable, safer and easier to operate. Between the two models, Toyota expects to sell 7,000 units each month in Japan alone (3,000 Alphards and 4,000 Vellfires) before other markets across Asia are even taken into account.

The vehicles were developed to incorporate the idea of a roomy and luxurious saloon space with a new and unprecedented sense of refinement. The new Alphard and Vellfire possess unshakeable presence with a comfortable ride, exceptional handling stability, and a roomy interior. The Alphard exterior emphasizes luxury, while the Vellfire exterior emphasizes boldness. In addition to high body rigidity, a newly developed double-wishbone suspension was adopted for the rear to achieve a luxurious ride and exceptional handling stability. Extensive sound and vibration dampening and an aerodynamic wind-noise reducing body shape realize a quiet ride at all speeds, befitting of a luxury vehicle.

2013 Pikes Peak Hill Climb, Practice Day 4

The fourth and final practice day of the 91st Pikes Peak International Hill Climb is complete. Tomorrow everyone will make any last-minute adjustments and get their cars, their bits and bobs lined up in the pits for Sunday morning's this-time-it-counts run.
The Unlimited runners took on the top section of the course today, Sébastien Loeb and his big-mouth Peugeot acing the practice test again with a time of 2:11. Rhys Millen's team proved its got the engine issues of two days ago in the Hyundai PM580T sorted out, posting the next-best time at 2:27.16. The reason we had to dip all the way into the hundredths for his time is because he nipped Romain Dumas by just .31 of them, the Frenchman in the Norma M20FC PP running the course in 2:27.47. In fourth came the Frenchman in the monster Mini, Jean-Philippe Dayraut six seconds back at 2:33.
Time Attack competitors, also on the upper section, were led by Paul Dallenbach in the Hyundai Genesis Coupe with a time of 2:36, Porsche pilot Jeff Zwart crossing the line six seconds later at 2:42, fellow Porsche driver David Donner coming in another six seconds back at 2:48. Dallenbach has topped three of the four practice-day sessions, sliding into the second spot behind Donner only on Practice Day 2.
