I suspect that if the lithium battery fails, the lithium battery will need to be replaced in order for the car to work properly...

Yip battery fails the car stops!

I saw a 16 year old Prius on the road the other day, so I suspect their batteries are lasting wel...

Mind you I have never seen any reports of these batteries failing, new technology though but none the less.

I know from speaking with some Lexus technicians that battery failures are rare as hens teeth and Lexus back up their cars with rarely a quibble, not sure how Mercedes would react though.

The automotive Li-On batteries are supposedly very tough cookies indeed. There's a lot of tech buried in the charging system to keep it all in good health. It's one of these queer situations where laptop battery technology was scaled up to power a car, they found out some interesting stuff that has since been fed back into laptop batteries...

I tried the E300e but didn't get why they put it with a diesel engine, I think they have gone over to petrol for the W213?

It is great as a company car though, the BIK benefits alone makes it a real contender for anyone that has a company car.

The current hybrid system is clearly a first generation system. You can only coast for very short distances (hundreds of metres rather than km), and as soon as you do more than rest your foot on the throttle the diesel engine fires up. It is fun trying to keep it coasting as long as possible, but it will never be far enough to have a significant impact on mpg.

I read recently that the 2nd generation hybrid Porsche Cayenne can now coast for a few km on electric power, and at a speed of up to 70mph. Presumably Mercedes, or their supplier, will have a similar upgrade waiting in the wings, or will adopt a plug-in hybrid for more models. You will still never get the extra cost back in fuel savings over a standard car, but back to the point of my original post again - surprisingly that isn't really the point.

Just an aside: in case Mercedes technical has nothing better to do than read forum posts - you need to better integrate the cruise control for the E300. It never coasts on downhill sections of the motorway, which means it is more economical to keep switching off the cruise control. That doesn't make a lot of sense.

My one never go for electricity, maybe one meter, it's the battery fail? Always start diesel engine.
