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.

Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.

Mazda recalls Takata airbags in B-Series

The Basics: Mazda will recall 19,000 examples of the 2004–2006 B-Series pickup. The Problem: The pickups contain Takata-sourced driver's side airbag inflators that could rupture in a crash. The spray of metal shrapnel could injure or even kill occupants. Injuries/Deaths: None reported in the Mazda pickups. However, a rupturing airbag inflator killed the driver in a Ford Ranger, which is identical to the B-Series. The Fix: Mazda will replace the driver's side inflator. If You Own One: Mazda plans to notify affected owners as soon as dealers have the replacement parts. More Information: Mazda already recalled 442,266 driver's side Takata inflators and 416,475 of them on the passenger's side. The affected models included the 2003-2008 Mazda6, 2004-2006 B-Series, 2006-2007 Mazdaspeed6, 2004-2008 RX-8, and some examples of the 2004 MPV. Ford also issued an expanded safety campaign for 391,394 examples of the 2004-2006 Ranger.
