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.

Mazda3 Skyactiv-Hybrid and CNG Concept shown in Japan

Mazda has received a tremendous amount of public and industry praise in the last few years, following up the successful introduction of its Skyactiv technology (powertrain and otherwise), with strong products like CX-5, Mazda6 and most recently, the Mazda3. At the Tokyo Motor Show, Mazda has taken yet another step forward with Skyactiv and the 3, showing the compact (called "Axela" in Japan) with an all-new compressed natural gas engine in the Skyactiv-CNG Concept.
The end result of the Skyactiv-Hybrid is fuel consumption estimated at something like 74 miles per gallon.
Mazda thinks that CNG-powered vehicles are due for an uptick in demand, and the company believes this new powertrain will add valuable breadth to the Mazda3 range. The CNG Concept is actually a duel-fuel vehicle, capable of running on either natural gas or gasoline. In fact, we're told that the high compression ratio (14:1) inherent in Skyactiv-technology gasoline engines makes conversion to CNG particularly simple.

Mazda's new turbo four fits in both the 6 and the 3

Despite the size differences, the Mazda CX-9 shares a lot with its smaller car-based siblings, the Mazda6 and Mazda3. That could allow Mazda to slot its full-sizer's new 2.5-liter, turbocharged four-cylinder engine under the hood of its smaller offerings. Pardon us while we do a happy dance. "[The 2.5-liter turbo] fits in a lot of our cars, and where we're actually going to put it is another question," Mazda North America vehicle development engineer Dave Coleman told Australia's Car Advice. Coleman specified that the turbocharged engine will fit in all the same applications that can accommodate the company's 2.5-liter gas and diesel engines. "Basically, that big space we used for the bundle of snakes exhaust manifold, the turbo is in that space too. They're all packaged to occupy the same space. It's exactly the same clearance as the exhaust manifold of the other engines." This kind of logic – if Engine A is the same size as Engine B, then both should fit in Car C – is what's lead us to imagine a turbocharged Mazda6 since the new engine was announced. In short, it's great news. Mazda's 2.5-liter turbo is a hell of an engine in the CX-9, and it's hard to imagine it'd be worse in a lighter vehicle. But just because it works from an engineering standpoint doesn't mean it's going to happen. At least, not soon. "It fits. I'm not a product planner so I don't get to make that call," Coleman told Car Advice. "It's up to the product planners to decide what they're going to put it in." The most obvious application for a turbocharged engine in the 3 or 6 is as a reborn Mazdaspeed model. But don't get too excited – Coleman said Mazda hasn't even gotten as far as building an engineering prototype with this engine. We're still firmly at the theoretical stage. And that's bad news, because it gels with what we've been reporting – that Mazda will wait a generation for future Mazdaspeed models. We just stopped doing our happy dance. Related Video:
