WAVE 2015: Metron 7 sets new record of 513 miles on one charge

Sometimes you just gotta push harder, faster, longer. Last fall, the Metron Institute team from Slovenia took their converted all-electric Mazda5 minivan on an impressive 457-mile journey from Bled (in Sloveniva) to Dubrovnik (in Croatia) without stopping to recharge at an average speed of 40 miles an hour. Today, as part of the WAVE Trophy 2015, the Metron 7 EV just finished up a drive of 826.1 kilometers (513.3 miles) on a single charge. The drive started in Berlin and ended in Karlsruhe, Germany. As you might suspect, a drive of this length on normal roads required a big battery pack. The total pack capacity was 108 kWh, thanks to the combination of the built-in 86-kWh pack that uses lithium polymer cells from Kokam and a 130-pound, 22-kWh external pack that Metron has developed that can charge the built-in pack while driving. The average speed of the 500-mile journey was 45 miles per hour (72 kilometers per hour) through rural countryside, towns, and some time on the highway. The drivers –Andrej and Jasna Pecjak – did not use air conditioning, but the fans were running. The weather was temperate enough that AC wasn't needed anyway these last two days. The Metron 7 was a part of the last two WAVE events and has been updated since the last record was set in October 2014. On the new record journey, the minivan was loaded up with gear, but the Metron engineers made improvements to the car in the last eight months: the side mirrors are smaller and they fitted a better aerodynamic cover underneath the vehicle, for example. Andrej said that the cost for the batteries was around $50,000, since some of the cells he got were used. Today's record is unofficial, but AutoblogGreen witnessed both the sealing of the charge port in Berlin and was in the car for the last 125 kilometers today.

Mazda halts Mazda3 sales for fuel tank problem

Mazda is issuing a stop sale and recall on 14,406 examples of the 2015-2016 Mazda3 in the US with build dates between May 21, 2015, and August 24, 2015, due to a possible fuel leak. There are no reports or accidents or injuries from this problem. According to the company, a defective fuel shut-off valve can allow gasoline to move from the tank and fill the charcoal emissions canister. If it gets too full, there can be a leak, which obviously carries the risk of a possible fire. The engine might stall, as well. Affected owners will be notified to bring their Mazda3 in "as soon as possible." Dealers will inspect the vehicles, and if a problem is found, the fuel tank and charcoal emissions canister will be replaced. During the downtime, customers will get a free rental or loaner car, as well. Those who are particularly concerned can also call Mazda roadside assistance to have their vehicle delivered for the check and possible repair.

A defect in the fuel shut-off valve may allow fuel to flow from the fuel tank into the charcoal emissions canister. With this condition, the check engine light may illuminate, and if the fuel exceeds the canister capacity, fuel leakage could occur, increasing the risk of a fire and/or engine stalling. Approximately 14,270 vehicles in the U.S. and 136 vehicles in Puerto Rico are affected. Owners of subject vehicles will be notified by mail in early October. They will be informed to bring their vehicle to the nearest Mazda dealer as soon as possible. Dealers will inspect the fuel tank to determine if the defect exists on the vehicle. If the defect exists, the dealer will replace the fuel tank and charcoal canister at no cost to the customer. A rental or loaner vehicle will be provided at no cost to the owner, until the vehicle is repaired for this concern. If there are no concerns, the vehicle will be returned to the customer. Should a customer not want to drive the vehicle to the dealership, they may contact Mazda's 24-hour Roadside Assistance service at 800-866-1998 and have the vehicle picked up and delivered to the dealership. There have been no reports of accidents or injury related to this issue.

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.
