I brought an RX400h against many other marques - had Audi, BMW, Merc amongst others before - and was after something different.
I believe that Diesel engines will soon be proven to be contributing to breathing difficulties by the micro particulates and NOX emissions. So it wil be another excuse for the Givernment to tax them more.
The Hybrid gives the same economy as a diesel, same/better performance and is incredibly quiet place to be.
It also allows me to raise two fingers to Kens charge.
I had no wish for a hybrid till I talked through and looked at the literature. So it was quite a snap decision.
Am I saving the planet? Probably not much on a Co2 footprint.
Am I less polluting ? Probably yes on Nox and other nasties.
