Prius's have now been around a while. What's the battery life looking like now - anyone got any experience. If the prophets of doom are right we should be seeing failures by now.

To get maximum life out of the Prius battery pack, the car's computer brain does not allow the battery to fully charge or discharge. Toyota says that for the best service life, the Prius battery likes to be kept at about a 60 percent charge. In normal operation, the system usually lets the charge level vary only 10-15 percentage points. Therefore, the battery is rarely more than 75 percent charged, or less than 45 percent charged.

If you're familiar with the Prius, you know there's a battery-charge indicator on the instrument panel. Toyota says this isn't the charge level per se, but rather a state-of-charge window. The top of the window represents about a 75 percent charge, the bottom about 45 percent charge.

According to Toyota, the life of the Prius battery pack is determined more by mileage than by time, and it has been tested to 180,000 miles. Supporting this are first- and second-generation Prius taxis in Canada that have reportedly traveled more than 200,000 miles without suffering any battery problems.

..for anybody who is is interested...found this on utube with regards to the plug in volvo v60 with a diesel motor.....

OK, so I'm a little late, but I've just watched the video and this Volvo seems great. All the performance of my old 850 T5 (and a bit more) which I reluctantly traded in for an efficient diesel family car, but with apparently staggering fuel economy. 50km electric range is just about enough for a one way trip on my daily commute, so if I could persuade my employers to provide a charging point I'd be laughing.

Where do I place an order?

Seriously though, this is probably going to be a 40k(+) car based on the prices of the rest of the V60 range. Won't stop me drooling, even though I'm sure it won't turn out as good as advertised.
