Geneva 2019, Jaguar I-Pace and Toyota Supra | Autoblog Podcast #572

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore welcomes the newest Autoblog staffers, West Coast Editor James Riswick and Assistant Editor Zac Palmer. First, the trio talk about the cars they've been driving: the 2019 Jaguar I-Pace and the 2019 Lexus LX 570. After that, they recap the exciting 2019 Geneva Motor Show, and all its highlights, disappointments and oddities. Then they answer some listener mail about the new Toyota Supra before closing the podcast with the Spend My Money segment.

Hyundai tops Toyota in annual CarMD Vehicle Health Index

CarMD has released its third annual Vehicle Health Index, which for the 2013 tracked the frequency and cost of repairs for "check engine" problems of 119-million vehicles built between the 2003 and 2013 model years. For the first two years of the index, Toyota ranked at the top of the list, but this year's results see Hyundai moved to number one, pushing Toyota down a spot.
The Korean automaker's rise to the top has been "fueled by its low repair frequency," according to CarMD. Toyota is second to Hyundai in lowest repair frequency, but Toyotas also have the highest average cost of repair. (Interestingly, General Motors vehicles have the lowest average.) Both Toyota's and Hyundai's manufacturer "health" ratings suffered this year, but Toyota took a bigger hit, which also is what helped Hyundai achieve the top ranking.
While Hyundai is the top manufacturer in the index, the 2012 Toyota Camry is the top vehicle. The best-ranking Hyundai was the 2010 Elantra (behind three Nissan models and four Toyotas), which took the number eight spot. Hyundai has six other vehicles in the top 100.

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.
