How Toyota's Le Mans racer may make its next Prius even better

The supercapacitor technology in the Toyota TS040 "offers great possibility for production car use." – Amanda Rice, Toyota Pop-culture junkies familiar with 1980s touchstone movies will hear the word "capacitor" and think Back to the Future. But the concept of supercapacitors being used in upcoming production models is being pushed by Toyota, not DeLorean. And because of that push, the future might look a little brighter for the Prius. The Japanese automaker will likely apply electric-motor technology used in Toyota's 24 Hours of Le Mans entry – the TS040 – in future versions of the world's best-selling hybrid, Australian publication Drive.com.au says, citing an interview with Toyota Motor Sports' Yoshiaki Kinoshita. Specifically, the racecar uses supercapacitors because they're effective at storing energy created when the vehicle is under braking, only to quickly redistribute it on demand for rapid acceleration. Kinoshita said Toyota may apply this technology to the Prius within the next five years. While declining to comment on specifics, Toyota spokeswoman Amanda Rice tells AutoblogGreen that the Le Mans vehicle "represents an advanced vehicle laboratory for hybrid vehicle and component development. The supercapacitor technology used in this vehicle with its fast charge and discharge capability offers great possibility for production car use." In her email, Rice added that the next-generation Prius will have smaller electric motors with greater power density and thermal efficiency, so let's add that to what we know or think we know about the fourth-generation model. Toyota entered two vehicles in this year's Le Mans race, and one of them had secured the pole-position and was leading much of the race before calling it quits 15 hours in because of electrical issues. Audi ended up winning the race, marking its 13th victory in the history of the French endurance contest.

Toyota JPN Taxi Concept is a Japanese riff on an English classic

As far as beasts of burden go, New York City's new - and much maligned - Nissan NV200 "Taxi of Tomorrow" isn't a bad one. It's space efficient, reasonably economical, and its simple construction should mean it's pretty robust over the long haul, too. But it lacks panache and a sense of occasion - let alone a sense of humor - three things this this Toyota JPN Taxi Concept we found at the Tokyo Motor Show has in spades.
Unfortunately, that's about all the information we have on this cheeky London-taxi-inspired showcar. Toyota hasn't provided much in the way of details, other than to proclaim that the five-seat JPN was "created with Japanese hospitality in mind" and it "aims to enliven city streets." Japan's livery landscape has long been occupied by traditional three-box sedans - models like the Toyota Crown and Nissan Cedric. The JPN Taxi at just over 171 inches would appear to offer both a tighter footprint and added whimsy, both of which are in the automaker's favor; we hear it hopes this concept will one day become the country's own version of America's yellow Crown Vic cab.
Toyota isn't providing powertrain specifications, but we like the airy feeling of the interior (Japanese cabs typically don't have cumbersome partitions between cabbie and passengers), the minimalist driver area with three screens, and the widescreen overhead video system for passengers that bookends the panoramic moonroof.

New Toyota semiconductors could increase hybrid fuel efficiency by 10%

Toyota may have an ace up its sleeve in the fuel economy wars, as it's developed a new type of semiconductor that will allegedly help the company's hybrids net a ten-percent improvement in fuel economy.
The tech is still in development, although Toyota is already reporting five-percent gains during testing, six years before it plans to implement the new semiconductor in production vehicles, meaning the ten-percent improvement doesn't seem like an untenable goal. That is, until you hear from Kimimori Hamada, the project general manager of Toyota's electronics division.
"We are aiming for great improvement in fuel economy and miniaturization," Hamada told Automotive News. "This is a very challenging target."
