2013 Pikes Peak Hill Climb, Practice Day 3

The third practice day of the 91st Pikes Peak International Hill Climb is done. While the other classes got running time on the middle and top sections of the course, qualifying times were set on the bottom section of the course for the Open, Open Wheel, Electric, Exhibition and Vintage classes.
Everyone managed to keep it on the black stuff today, Greg Tracy setting the fastest time ahead of Hiroshi Masuoka, both men driving the Mitsubishi MiEV Evolution II four-wheel-drive prototype. Not even half a second behind Masuoka came Nobuhiro "Monster" Tajima in his Monster Sport E-Runner, who has taken about 18 seconds off his time since the first practice day. Rod Millen was the fourth fastest on the day in his Toyota TMG EV POO2.
Topping the Open Wheel class was Clint Vahsholtz, followed by Donner Billingsley, Andy Figueroa and Rodney O'Maley. The only driver in that class not to be given a time today was Dan Novembre. Kenshiro Gushi took the Exhibition class today as his Lexus IS F CCS-R made it up the mountain in 4:27.248, followed by Sage Marie in the Honda CR-Z at 5:19.591. Simon Pagenaud and his Honda Odyssey weren't classified.

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.
