In the studio to discuss the topic of electric cars and other environmentally friendly engines is Andreas Bremer, Managing Director of IFA Market Research Bremer + Partner.DW-TV: Would you order the electric car "Greenster" for yourself? Andreas Bremer: I’ll wait a little longer. But it is a fascinating car, I really like it. What's interesting is that it has a range of 300 km. I wonder if that's true in everyday life or just on a test drive. We'll have to see. But it's an intersting car.  DW-TV: A very expensive car: 180-thousand euros. Who can afford this? Andreas Bremer: Not many people, obviously. But there's only one so far. Maybe it'll get cheaper when they produce 100,000 of them. DW-TV: The price is a problem. The financial aspect certainly seems to be the biggest challenge. We know that green cars cost more than normal cars. But there must be other problems why demand is so low: What about the infrastructure? When will this be ready? Andreas Bremer: That will be a while, I'm afraid. Look at gas engines and how long it has taken for them to become so common that you don't need to sit down for two days to plan every trip. It's got better but it's still not easy. And if you're driving an electric car then there are a lot of problems involved. I come from Essen, and even I can't think of any power station where you could fill up your battery. That's a major problem. And then of course the costs just have to come down to a level of roughly 25,000 euros which is what we're paying for a new car. DW-TV: It's interesting to hear that although the inventor works for Porsche, Porsche is not involved in the "Greenster". Other big car makers on both sides of the Atlantic have already lost out on hybrids. Here Japan is clearly in the lead. Why are the big car companies so dismissive of green car technologies? Andreas Bremer: I don't know that they're really dismissive of the technology itself. But we're talking about a high-risk investment. Currently,...
