The Toyota Prius

One thing that does annoy Disgruntled from Bradley Stoke is the Toyota Prius. Don’t get me wrong, it is an impressive technical tour de force and extremely innovative. What really annoys me is what it represents. There are far too many people buying it to make a statement, saying “look at me, I’m environmentally conscious.” But that’s just it – it isn’t.

First of all, let’s consider some technical specifications:

There are six cars to consider here, all of a similar size. You can see than the Prius has very good urban cycle figures, although the VW is better, which means that it is good around towns. Get outside of town though and the Ford Focus diesel becomes better, and the VW is even better. So if you are going to do a lot of out of town driving, the Prius scores relatively badly against a turbo diesel. If you do a lot of town driving, the Prius is not a bad option, but it is not the best – the VW beats it hands down, and is £5000 cheaper!

And this is before you consider the life cycle of the car. The Prius uses Lithium ion batteries, and Lithium is a rare metal which requires an energy intensive process to extract it. The battery cells will not last the lifetime of the car and will need replacing, and the recycling of the cells is also energy intensive. This means that taking into account the whole lifecycle of the car, all of the non-hybrid vehicles in the table above are in fact more environmentally friendly and cause less emission of CO2 and other pollutants. If you are purchasing a Prius, all you are doing is making a fashion statement. If you really wanted to be environmentally friendly when driving a car, you would buy the VW and save yourself five grand in the process.
