Porsche 911 Carrera 4, Alfa Romeo Giulia Quadrifoglio and a chat with Jean Jennings | Autoblog Podcast #626

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Road Test Editor Zac Palmer, Associate Editor Byron Hurd and special guest Jean Jennings. The gang kicks off with a discussion about the cars they've been driving — 2020 Porsche 911 Carrera 4, 2020 Alfa Romeo Giulia Quadrifoglio and the 2020 VW Tiguan. They shift gears to talk about the latest news gleaned from a press conference concerning the 2021 Supra, then, they reach into the mailbag to help a listener buy a performance car. Lastly, Greg has a chat with special guest Jean Jennings.

Scion trying to build business case for FR-S convertible as Subaru bows out

Hope may remain for a convertible version of the Scion FR-S, according to a report from Ward's Auto. You'll recall that rumors were swirling about the feasibility of a rear-drive Toyobaru convertible as early as October, and that back in November, Subaru - which makes the FR-S, Subaru BRZ and Toyota GT86 - essentially nixed the idea of an open-topped variant.
"We make the car, so if we don't make it, it can't happen," brand chief Yasuyuki Yoshinaga told Automotive News, according to Ward's, at the Tokyo Motor Show. "Our engineering department told me that losing the entire roof requires a complete redesign of the structure. It would need a big change."
Despite Yoshinaga-san's arguments against a droptop variant, Toyota is apparently still considering the model. Speaking to media at the 2014 North American International Auto Show, Scion's US vice president, Doug Murtha, hinted that the rear-drive droptop was in the works.

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.
