Hi Ruth,

Not a word of a lie: I picked one up this morning from Honda to test for the week. Paddy has driven it for longer so he'll give you his opinion too, but my first impressions are better than expected. Until recently, hybrids were designed first and foremost for the American market and they were quite different to drive to conventional cars. Most of that is still true, but both the Toyota Prius and Honda Insight are more normal than what has gone before and even more efficient.

The official fuel economy and emissions figures of the Insight are pretty impressive though, at 4.4 - 4.6 litres/100km and 101 - 105g/km of CO₂ depending on which version you choose. The Toyota Prius boasts even better numbers, though it's a few grand more expensive.

So far I've averaged about 5.4 litres / 100km in mixed driving and I'd expect that to be pretty representative unless you're on a long motorway run, where the average might improve further.

I prefer the interior of the Insight to the Prius', even if Honda has used too much hard plastic for my liking. The Honda is more conventional, despite the presence of strange plant graphics in the dashboard to tell you how economically you are driving. You sit low down and there's loads of space for five adults and a fair amount of luggage.

The steering wheel on our test car is really shiny and a bit slippery, but I'm sure that'll change with use. Its controls for the stereo are nice and tactile though. Shame I can't say the same for the spindly gear lever, but there you go.

Overall it's easy to drive and while it's no performance car it keeps up with traffic easily enough. That aside, the Insight's engine is commendably quiet, unless you really put your foot down. However, I noticed that road noise is quite prominent in return.

I'd personally prefer a regular car to either the Prius or Insight hybrids. If fuel economy were the most important factor I'd opt for a good turbodiesel model. There is a lot of choice on the market for the €22,000 - €23,000 asking price of the Honda.

There has been a lot of debate about the benefits of hybrid cars, but few would disagree that they are a step in the right direction. The principle of the current crop of hybrids, for those that don't know, is that a standard petrol engine is combined with an electric motor, with the result being better fuel consumption and lower emissions. The original Toyota Prius was the first mass-produced hybrid on sale and Toyota has just released the third generation of the model and it promises to be more refined and cleaner than ever.

There are other alternatives such as the Honda Civic Hybrid, which isn't bad either, or the Honda Insight, while at the top end of the scale Lexus does three hybrids, the GS 450h, the LS 600h and the RX 450h. In the case of the Lexus hybrid technology it's as much about giving the cars higher performance as it is increasing efficiency.

A hybrid is cleaner in so far as official emissions figures are very low. The Prius emits less then 90g/km, which will make it the cleanest petrol car on sale in Ireland. In some cases you could get better fuel economy from a diesel engine though.

With a budget of €40,000 you could easily get into the new Prius when it arrives in October, as the car is expected to cost about €28,000 and this will be a very cheap car to run, so it seems the natural choice. Bear in mind that even cleaner technologies will arrive soon, including those in the Opel Ampera and even a new plug-in version of the Prius.
