How are BYD's hybrids (all PHEV now, I believe) more advanced than Toyota's? I'm also curious as to BYD's build quality and longevity of components. Toyota is a known quantity; their vehicles typically run for years with few needs other than routine maintenance. I've read & watched lots of very positive reviews of BYD hybrids and full electrics based on a few hours' use, or maybe a few days. These cars do look pretty good and are competitively priced in most markets, but they have to be compared apples-to-apples, over multiple years, to get a sense of what it's like to own one.
