Prius – technology for a reason
Posted by Colin Hensley on March 14, 2009 in Green Technologies
As I said last week, it was great to have the chance to launch the new Prius in Europe last week in Geneva. I’d like to take a few lines now to describe some of the impressive technical achievements that we see gathered in the new Prius.
Of course, the powertrain is the tour-de-force of the car, a full series/parallel hybrid offering EV drive and very low CO2 in the combined cycle. It’s also very widely covered in various media, so let me move on to a couple of other features.
The solar roof that powers a fan to bring in cooler outside air is a feature that is proving to be a much talked about addition. Of course, it’s especially interesting for the countries where the sun really shines a lot (from my seat in Belgium, I think I can still just about remember what the sun looks like.) The system not only makes the car cooler when you get in, it also then means you need less energy to cool down the car to a completely comfortable temperature.
The touch tracer display is also a new feature, this one with a safety benefit. As you move your thumb (or finger) over the buttons on the steering wheel, you can actually see in the display which button it is, and so easily can do what you want to do. This means your eyes spend less time off the road. We know from our accident studies in the past that lack of recognition of a dangerous situation is a critical cause of accidents, so every extra millisecond you have can make a difference. For similar reasons, the Prius also has a head-up display showing the information you want to know as you drive, such as your speed, or where to turn when you have a navigation system.
I’m really looking forward to having a chance to drive the Prius, so I guess I’ll have to start begging Dirk (my colleague who arranged the iQ) as soon as we have the cars here.

Those of you that follow our Twitter will know that I’m just back from the Geneva Motor Show. We had a very busy time at the show, for a number of reasons. Firstly because the industry is under intense scrutiny at the moment, as we are doing our best to weather a really tough crisis. Secondly, we launched the new Prius into Europe at our event last Monday evening, alongside the new Verso, (C-segment MPV.)
It was great to have a chance to meet Akihiko Otsuka, who is the Chief Engineer of the Prius, and to talk to him about his hopes, aims and anecdotes of when he led the team that developed the car. When I wrote a few weeks ago about the Prius and about the new engine, I couldn’t reveal that the CO2 figure for the combined cycle in Europe is just 89g/km. I also didn’t know all of the efforts that were made in so many areas of engineering the car to do everything to reduce the fuel consumption during real-life driving. I did know the CO2 figure on Monday, and that motivated me to really pick Otsuka-san’s brain. Next week, I’ll write a bit more technical blog on that, but for today I’ll leave you with one little gem. When developing the new Prius, Otsuka-san researched loads of things, even including large ships, which are know for running on highly efficient internal combustion engines. We can learn from everywhere, we just have to be unafraid to look.
