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.

2016 Mazda CX-9 First Drive

Automotive enthusiasts tend to obsess over spec sheets. How else could we know which cars and trucks are the quickest in a straight line, hold the road with the greatest tenacity, or tow the biggest trailers? More succinctly, what ammunition would we have in the seemingly endless back-and-forth of Internet forums if it weren't for specifications? Mazda's engineers think they've found a better way. The 2016 CX-9 has less horsepower than its primary competitors. The only engine available is a turbocharged four-cylinder, hooked to a six-speed automatic. Drivers won't miss the 23 horsepower (or more, as we'll soon explain) lost in the changeover from 2015 to 2016, because Mazda applied its holistic Skyactiv approach to the largest vehicle it offers. That means less weight and, ultimately, more fun. Or so they say. Are they right? Yes. And no. Most of the time, in normal on-road driving conditions, the 2016 CX-9 is the most fun you can have with three rows. But the real-world tradeoff didn't go off completely without a hitch. Reasoning that real-world performance is more important than ultimate horsepower, Mazda specified a four-cylinder for its big, three-row SUV instead of a more traditional V6. Let's get those all-important specifications out of the way: All 2016 Mazda CX-9s are fitted with a 2.5-liter turbocharged four-cylinder with 250 horsepower and, impressively, 310 pound-feet of torque at just 2,000 rpm. Unless you decide to use 87 octane, in which case you'll be limited to 227 horsepower. Mazda doesn't think owners will actually notice the difference in power levels, so there's no Premium Fuel Recommended sticker on the back of the fuel door. Mazda utilized some clever turbo trickery to deliver a diesel-like torque curve from its gasoline-fueled engine, which makes the small-displacement powerplant feel lively at low engine speeds. The flipside is that the CX-9 runs out of breath as the needle swings across the upper reaches of the tach. While that simply wouldn't do for a sportscar like the MX-5, in the CX-9 it's not necessarily a deal breaker. One benefit to the downsized engine is that it doesn't guzzle fuel. The EPA rates the CX-9 at 22 miles per gallon in the city and 28 on the highway. Drop one mpg all around for the all-wheel-drive model. Those figures beat out all the CX-9's most natural competitors, including the Honda Pilot and Toyota Highlander. The turbo-four Ford Explorer matches the 28-mpg highway figure, but loses by three in the city.

Mazda 767B crashes during Goodwood, suffers heavy damage [UPDATE]

Update: Autoblog has learned that the Mazda 767B wrecked at Goodwood was being driven by Seniji Hoshino. He was not seriously harmed and was able to walk away from the crash. Hoshino's car was chassis 001 and scored a win in the GTP class of the 1989 24 Hours of Le Mans. A Mazda 767B Group C racer suffered a crash the Goodwood Festival of Speed that tore off the rear wing and did some fairly serious looking front end damage. According to Jalopnik, the racer was taking a timed run during the event's famous hillclimb when it went into the hay bales. The driver is reportedly okay, though. We've reached out to Mazda and Goodwood sources to identify the pilot in question, with no luck so far. Look for an updated post later in the day if we get any answers on that front. Images of the sad wreck seem to be populating on Twitter feeds as we write this. The racing Mazda clearly suffered a big hit today; painful to look at even after the fact. But we're not sure if the damage is beyond the abilities of skilled factory workmen to fix. Our collective fingers are crossed. Mazda has a major presence at Goodwood this year, including the event's art installation. Among all of its vehicles, there are two privately owned 767Bs. These racers have a four-rotor engine, said to be good for more than 600 horsepower in racing trim, and are predecessors to the famous 787B that scored an overall win in the 1991 24 Hours of Le Mans.
