That's just a market gimmick. Honda is a novice for diesel engine technology. A thin metal walled engine is no innovation in diesel. If japanese engines are supposed to be reliable, they don't win awards for performance/innovation either (Pls name something reliable from Japanese?). This is what Koreans are doing what Japanese did 30 yrs back. Honda/Toyota are Hyundai's of 1970-80's, Just look at the automarket 1970-80s. Mimic state of the art European/American stuff with cheaper & very basic design, though propagate in media like it has moved the world into the 22nd century. For eg. Mechanical variable Valve timing introduced by FIAT in 1960s is advertised by Honda as VTEC. All Honda did is think a new name for something that FIAT doesn't even advertise these days. Less power, less stress, smaller service intervals, hair driers!! This is Honda's last attempt to crack European market in which they have already lost. 1.6 ltr, 110 bhp & 300 NM. That's 10 yr old stuff for European in VW/FIAT engines. As far as Palio vs OHC of same era is concerned, it's a pity to see those OHC tin boxes where every Palio i have seen till date is still perfectly put together with no sign of aging. Good paint job/cosmetics & it would look like a car bought last yr. You be rest assured, A palio has gone through way more abusing than an OHC because of "failed" resale value & multiple owners every year. Every OHC looks like another box going to a trash bin anytime, whereas every Palio looks like a rough tough-stud. Mind your RELIABILITY if this what you mean by reliability!!
