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.

RingBanana Miata breaks 9-min Nurburgring barrier

The RingBanana is a cheap Mazda MX-5 Miata on a screaming mission: to lap the Nurburgring in under nine minutes. And let us emphasize the word "cheap." The team wanted the least expensive Miata they could find that still ran, and then wanted to spend the least amount of money possible in order to hit their target mark. We don't know how much they spent on the Ringbanana, but they were so indiscriminate about the purchase that they don't know what year the car is. They only know that it's got 90 horsepower, green springs, Fulda tires, and "it's completely crap." After setting a base lap of 9:21.8 the guys behind the project figured they'd have a fair bit of work. Turns out a new set of Kumho V70A semi-slick, road-legal race tires paired with Gabriel Pirana's driving is all they needed. With just that mod Pirana set a lap time of 8:59.9, and that was while having to deal with one spot of slow traffic that was getting around a stricken car. According to Wikipedia, this puts them between a 2010 Range Rover Sport Supercharged and a 2007 Chevrolet Cobalt SS. Even though the team achieved its goal on its first attempt, the Ringbanana game isn't over – there's probably a suspension mod in the near future while the guys figure out just how quickly they can go. The video above does a good job of showing just how fun it can be driving a slow car fast.

Mazda struggles to meet demand on rising sales

For Mazda there's good and not-so-good news on the heels of strong US sales in 2012: demand is high - especially for the Mazda3, Mazda6 and CX-5 - but supply is low, TheDetroitBureau.com reports. That's partly because all Mazda production happens in Japan, since it ended its alliance with Ford and pulled out of a joint venture with the blue oval building cars in suburban Detroit last year.
In 2012, Mazda sales here jumped 26.4 percent, but 2013 sales through August have just been keeping pace with the overall US auto industry, increasing at a rate of 6.8 percent. Mazda North American Operations director of marketing and communications Jeremy Barnes says that sales have slowed because the company is facing challenges delivering products here.
