Autoblog Minute: VW finds CO2 'irregularities', Takata dropped by automakers, SEMA recap

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.

2020 Mazda CX-9 gets more torque and second-row captain's chairs

The 2020 Mazda CX-9 is here, and it’s even more enticing than the 2019 model year SUV. ItÂ’s not a full redesign, but Mazda shook up the features list to make it more competitive with other three-row crossovers. Most notable (arguably) of all changes comes from a small increase in torque — the 2.5-liter turbocharged four-cylinder gets bumped from 310 pound-feet of torque to 320 pound-feet. Horsepower remains the same at 250 horses. Those figures are only applicable when using 93 octane fuel. They go down to 227 horsepower and 310 pound-feet of torque when on 87. Another new feature is an off-road traction assist button, replacing the traction control button. This new feature is meant to help when navigating rougher terrain. HereÂ’s how Mazda describes its function: “When the diagonal wheels lose traction, off-road traction assist will stop reducing the engine torque and increases the brake force on the wheels without traction. This transfers power to the wheels still on the ground to help allow the vehicle to regain traction and continue the drive.” WeÂ’ll be interested to see how this helps the CX-9 on a snowy Michigan winter day soon. The number of standard features on the base Sport trim is up, too. Now all CX-9s get heated front seats, a power driverÂ’s seat, rain-sensing windshield wipers, heated outside mirrors and auto high-beams. Additionally, Mazda made its full suite of i-Activsense safety features standard. This includes adaptive cruise control, lane-keep assist and other driver assistance niceties. Mazda is also adopting the new key fob design of the Mazda3 for the CX-9. Optional on the Touring and Grand Touring are second-row captainÂ’s chairs. Previously, Mazda only offered bench style seating for the CX-9, so this addition could be a huge turn-on for some folks in this segment. The chairs have armrests, and the lack of a center pull-down means Mazda had to redesign its cupholder layout in back. In CX-9s equipped with the chairs, the cup holders and USB ports are now integrated into the backside of the front center console. If you opt for the captainÂ’s chairs in the Grand Touring or Signature trims, the seats are heated.  Pricing does increase a fair amount for the 2020 CX-9. A base front-wheel drive Sport is now priced at $34,835 including destination, a $1,510 increase from last yearÂ’s base price. The top of the range only got $750 more expensive, though, as the Signature starts at $47,160.

Mazda G-Vectoring Control makes driving better without you knowing

Mazda has just spent eight years developing a new technology that will make its new cars a lot more fun to drive, even if you have absolutely no idea that it's working. And subtlety's the point, Mazda engineers told us at a press event at Mazda Raceway Laguna Seca. In fact, the effects of what they've dubbed G-Vectoring Control are so fine that the marketing and PR teams are at a loss for how to do their jobs with it. "The engineers have done their work," said Mazda Director of Communications Jeremy Barnes, "But how do we get the message across?" The basic premise is this: G-Vectoring activates only when the car's on-board computer reads simultaneous steering and throttle input. The data — including throttle position, steering angle, and, crucially, how quickly you're adjusting the steering angle — are then funneled through an algorithm to reduce engine torque, which transfers vehicle weight, adding more grip to the wheels that need it. The system will appear first on 2017 Mazda6 sedans arriving in showrooms later this year, followed by the 2017 Mazda3. Actually, "subtle" does not even begin to describe the effect. G-Vectoring Control can detect as much as one tenth of one degree of steering angle, and changes the cornering forces only 0.1 to 0.5 g as a result. "That's less than the human body can feel," explained Vehicle Development Engineer Dave Coleman. In practice, G-Vectoring reduces the steering angle at turn-in, as well as the rate at which one turns the wheel. To demonstrate, Director of R&D Kelvin Hiraishi rode shotgun with us in a specially equipped Mazda6 that allowed him to turn G-Vectoring on or off at the push of a button (production cars will always have it on). Hiraishi had us drive a number of courses, including Mazda Raceway Laguna Seca itself, while an engineer measured our steering inputs with a laptop Matrix'd into the car's electronic brain. I drove the same course several times with the same car in the same conditions, with cruise control locked and the system turned on or off. Lo and behold, with G-Vectoring activated, the engineer's output graph showed that my steering inputs were indeed reduced ever so slightly. There were two times that G-Vectoring was markedly noticeable. The first on a turn with a minor banking toward the outside, and the second was during cornering over an artificially wet section of the course — in other words, when the car was at the limits of adhesion.
