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.

This classic Firebird restomod swallowed a Prius

It takes an unusual eye to look at a 1967 Pontiac Firebird and see the Toyota Prius hidden inside. But that's just the kind of eye that a creative mechanic known online as "Bill the Engineer" has. Bill is updating his old Firebird into a true classic for the 21st century and has documenting the changes over at Priuschat and EcoModder. The TL,DR version of the story: he's replacing the worn-out powertrain with the gas-electric hybrid one from a Prius V, because it turns out the two vehicles have almost exactly the same wheelbase. Bill, who's from Columbus, Ohio and doesn't want his full name used, said in his posts on the conversion project that he's made many memories with this vehicle since buying it back in 1979. Since then, a few moves, a few decades, and some time in storage meant that the car would no longer function as he wanted it to. As he wrote, "when it comes to mice in the vehicles IT IS WAR." His solution is to make new memories and making a greener vehicle, and so we wanted to ask him how things have been going. Bill's been traveling a bit recently, but told AutoblogGreen that he's now figuring out the next steps for this amazing and complicated project. "I always plan things out before I do them," he said. That's the only way something like this can work. ABG: I think we have to start with what gave you the inspiration for this project. Was it simply that you had the two cars and wanted to see them merged into one cool mashup, or was it something else? "One day my wife wondered out loud if the car could be converted into a hybrid... The rest is history." Bill: I have been the owner of my 1967 Firebird convertible since 1979 when I bought it for $750.00. I drove it for years and made many memories. Afterward it was in storage for many years during which time mice at their way into the car and trashed the interior and wiring. I started working on a conventional restoration but always ran into major problems with hidden corrosion, electrical issues and an engine on its last legs. The car was never going to be as nice as I wanted going the conventional route. One day my wife wondered out loud if the car could be converted into a hybrid like our two daily driver Prii. That got me thinking about how it could be done. The rest is history... ABG: It looks like you started in late 2014. Have things gone well since then, or has it been one hassle after another? What has been the biggest setback, and what were the biggest victories?

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.
