Dear Tarabell I usually get bored reading long articles, but you elaborated HCH ll 's efficiencies in such a beautiful way possible that I've been reading your article in paragraph wise & applying the techniques mentioned practically, helped me understand a Hybrid so well. I even enjoyed acting upon your barefooted advice. I've been struggling to know something about HCH ll, but grateful to you, you saved us all time, almost a complete article on any car. Thank you for your precious struggle which helped complete this article. May you have a satisfied & a happy guided life. Regards
