Audi scores first CA autonomous car permit

Audi apparently knows how to get to the front of a line when it comes to driverless vehicles. The German automaker had the honor of being the very first company to receive one of California's new autonomous vehicle driving permits. It was a perfect followup to it being among the earliest ones to get a similar permit in Nevada a few years ago.
Getting the California permit is a big deal for the automaker because the state is also home to Audi's Electronics Research Lab. Among its current projects, Audi is working on the human-machine interface to communicate whether the person or vehicle is actually controlling the driving. All of this hard work is building toward offering autonomous motoring in freeway conditions in the next five years, Audi claims.
Obviously, autonomous vehicles from companies like Google have been testing in California for a while, but the new permits are meant to safeguard public safety when testing the driverless cars in public. The new rules include things like always having a person able to take control and more stringent standards like registering each autonomous car and the eligible drivers with the state. Any models testing on public roads also have to carry at least $5 million in insurance in case of injury, death or property damage.

Audi says new 48 volt micro-hybrid system improves fuel economy, paves way for electrification

Most cars use a 12-volt system to power their electrical components. But, with more and more electric bits and bobs being added to new vehicles, a dozen volts is looking a bit weak these days. In fact, Audi says that standard 12-volt systems are being stretched "to their very limits." Enter 48 volts. If used in a car that gets 40 mpg, that would translate to around 43.5 mpg. Audi is testing a supplemental 48-volt electric system in two prototype vehicles – modified mild-hybrid versions of the A6 TDI and the RS 5 TDI – in order to add in more electric technology (an electric compressor, for example, to improve acceleration) and "convenience systems for dynamic chassis control." Audi says it has more applications in the pipeline, but the overall gist is that the German automaker sees 48 volts as an "important building block in electrification strategy." As you can see in the picture above (click to enlarge), the RS 5 TDI concept uses a li-ion battery installed in the back of the car and an alternator to provide 48 volts when the engine is off. Audi says that the 48-volt system can save up to 0.4 liters of fuel per 100 kilometers. To put that into US numbers, if used in a car that gets 40 miles per gallon today, that would translate into a bump up to around 43.5 mpg. The Advanced Lead Acid Battery Consortium (ALABC) is also working on a 48-volt system to improve fuel economy and we've got a deep dive of Audi's electric turbocharger here. Even more powerful and efficient – the new 48-volt technology from Audi Important building block in electrification strategy More voltage and more power for new technologies Scalable platform concept suitable for wide-ranging uses Ingolstadt, August 25, 2014 – Audi is to upgrade part of its vehicle electrical system from twelve to 48 volts. The move represents another technical building block for facilitating the integration of new automotive technologies while increasing the power and efficiency of its cars. "We are using the full bandwidth of electrification in our drive principles strategy. Running part of the vehicle electrical system at 48 volts plays a central role in this," commented Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "It enables us to make more energy available.

Rivian R1T, Mini Cooper Electric owners happiest with their EVs

The J.D. Power 2023 U.S. Electric Vehicle Experience (EVX) Ownership Study is out, and there's change at the top. With the swelling adoption of electric vehicles in the U.S. over in the past two years especially, the third year of the EVX study changes focus to first-time EV buyers. Those two factors encouraged change at the top of both premium and mass-market segments. Among premium EVs, the Rivian R1T pickup scored overall victory in its first year of eligibility with a satisfaction score of 794 out of 1,000. The Tesla Model 3 takes second place with 759 points. Tesla had won the top two premium spots in the study in 2021 and in 2022. The average score in the premium segment was 756. The Tesla Model Y (754), Audi E-Tron (735), and Polestar 2 (724) filled out the list of the five eligible models this year. Among the ten eligible mass-market vehicles, the Mini Cooper Electric nabbed the overall win by scoring 782. The Kia EV6 came second with 762 points, keeping Kia in the top two; the Kia Niro EV won the mass-market segment the previous two years. The Ford Mustang Mach-E (742), Hyundai Ioniq 5 (738), and Volkswagen ID.4 (735) completed the top five, the Niro EV (733) in sixth. All were above the segment average of 730. The four models fell below the segment average were the Ford F-150 Lightning (723), Chevrolet Bolt EUV (716), Chevrolet Bolt (711), and Nissan Leaf (698). How are the scores derived? J.D. Power worked with EV app maker and research firm PlugShare to get owner responses in ten areas: accuracy of stated battery range; availability of public charging stations; battery range; cost of ownership; driving enjoyment; ease of charging at home; interior and exterior styling; safety and technology features; service experience; and vehicle quality and reliability. Brent Gruber, executive director of the EV practice at J.D. Power, said, "Recent vehicle launches from both new brands and traditional automakers have had a profound effect on what factors are most important in the ownership experience. Today’s EV owners are looking for quality, reliability, driving enjoyment, safety and technology features." The Mini, in fact, scored highest of any premium and mass-market EV in the studyÂ’s highest-weighted index factor, quality and reliability.
