I'm very impressed with my Lexus LS430 which i've enjoyed driving for the last few weeks. I bought it just to try out the Lexus car ownership experience. It has confirmed my decision to buy a newer Lexus in around year's time. One of the downsides of the LS430 is the fuel consumption, but I knew it was going to be bad before I bought it. So, I was wondering whether the hybrid models (GS, RX, LS) have significantly better fuel economy than their petrol-only counterparts? I would need to see at least a 15-20mpg improvement in real-world fuel economy before it made a significant financial difference to me.
What sort of fuel consumption figures are you guys achieving on your Lexus hybrids?
