Volkswagen's diesel emissions scandal gets a new wrinkle, US regulators hit Takata Corporation with a substantial fine, and we head to Las Vegas for a look at tuner paradise at the 2015 SEMA show. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Volkswagen's diesel emissions scandal gets a new wrinkle. US regulators issue a significant fine to Takata Corporation. And we take a peek inside tuner paradise at the 2015 SEMA show. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. The VW diesel emissions scandal, first brought to light in September, gets a new wrinkle, as an internal investigation by the German automaker revealed [00:00:30] irregularities in CO2 emissions that could affect approximately 800,000 vehicles. VW estimates the issue could pose a 2-billion euro economic risk. VW claims that most of the vehicles affected have diesel engines, but industry analysts say a 1.4-liter gas engine is also affected. VW says that fuel consumption figures were set too low during the CO2 certification process. During all of this, sales of some diesel-powered Volkswagen, Audi, and Porsche models [00:01:00] have been halted. Takata Corporation is back in the news in connection with its deadly airbag scandal. Federal regulators fined Takata $70 million. If the parts supplier does not comply, the fine could balloon to $200 million. Takata was also dropped this week by its biggest customer, Honda. And now, Toyota and Mazda will be following Honda's lead in dropping Takata. We're also hearing that Mitsubishi and Subaru are considering a switch in air-bag inflator suppliers. SEMA 2015 [00:01:30] came and went. We saw offerings from Mopar, like the AWD Challenger concept. Honda unveiled a Ridgeline that it will race at the Baja 1000, which gives us a hint at what future production model could look like. The celebrity presence was also felt in Vegas as it always is. Kid Rock brought a Duramax Diesel Chevy Silverado, and Acura restored and presented Ludacris with his now famous 1993 Acura Legend. Those are the highlights from the week that was. Be sure to come back on Saturday for my full recap, [00:02:00] where I'll have some added insight into Hyundai's foray into the luxury sector. For Autoblog, I'm Greg Migliore.

Mazda and Isuzu to collaborate on a new pickup truck

After decades, Mazda has finally untangled itself from its relationship with Ford. The last vestige of that partnership is the BT-50, a rebadged version of the global Ford Ranger pickup truck. Once the BT-50 ends production, Mazda has announced that it will collaborate with Isuzu to develop its next generation of pickup trucks. The BT-50 was co-developed with Ford's Australian division. In their current iteration, the BT-50 and its Ranger twin were never on sale in the United States. Mazda's last pickup in the US was the B-Series, itself also a rebadged version of the old Ford Ranger. Isuzu pulled out of the US passenger vehicle market in 2009, although it still sells commercial vehicles here. Isuzu, continuing a long and complicated relationship with General Motors, co-developed the diesel engine that currently powers the Chevrolet Colorado and GMC Canyon. In select markets, Isuzu sells a rebadged version of the Colorado as the D-Max. Details on the Mazda/Isuzu tie-up are scarce. A single press release simply says "Isuzu will produce next-generation pickup trucks for Mazda, based on Isuzu's pick-up truck model." This isn't the first truck collaboration between the two companies. Since 2004, Mazda has sold the Titan, a rebadged version of the Isuzu Elf commercial truck. The Elf is sold in the US as the Isuzu N-Series. Those in the US hoping for a new competitor in the midsize-truck segment shouldn't get their hopes up for the new truck. There are currently no plans to bring them here. There is hope, though, that Ford will bring the Ranger replacement stateside sometime in the next few years.

Mazda still has a team working on rotary engines

The flame still burns within Mazda to stage a rotary engine revival. Before you start getting excited, it's way too soon to start saving money for the fabled, next-gen RX-7 or RX-8. Still, company boss Masamichi Kogai confirmed to Autocar that the Japanese automaker has an engineering team dedicated to improving the Wankel. This development group has the hard task of trying to make the rotary stack up to modern internal combustion engines in terms of emissions and fuel-economy standards. Neither factor were ever exactly Wankel's strong suits. Kogai described them as working "very enthusiastically" to Autocar. The boss didn't discuss any future RX-vehicles or the size of the team, however, a report from last year indicated that there were 30 engineers in partnership with universities to update the engine's design. After problems keeping up with emissions and fuel economy, Mazda built it's last rotary for an RX-8 in June 2012. Since then, there have been intermittent rumors of a return. One possible solution was a design called the 16X that was supposed to offer more torque and better fuel economy. Another possibility was a small-displacement unit as a range-extender in an electric Mazda2. Rumors of a new RX-7 have been heard for years. In 2013, Kogai clearly said that it wasn't happening. When asked again last year, he reiterated the same point.
