Japanese Engineers Tore Down a Chinese Engine in UK — What They Found Shocked Them!

0:00 Toyota’s six-millionth engine 1:14 MG Rover’s collapse and the K-series 2:57 How BYD built its own technology 3:47 Japanese engineers take apart the Atto 3 7:10 Why petrol engines were the old guard’s advantage 8:50 BYD’s efficiency claim and Geely’s challenge 11:08 Chinese plug-in hybrids in British showrooms 16:37 The shift from learning to leading I trace how Toyota’s Deeside engine plant reached six million engines, and why the old assumption that the best hybrid petrol engines must be Japanese is being challenged. I follow the story from MG Rover’s collapse and the K-series engine to BYD’s rise, its integrated electric-car technology, and the Japanese engineers who took apart a BYD Atto 3 to understand its low-cost approach. I also examine BYD and Geely’s thermal-efficiency claims, the Chinese plug-in hybrids now appearing in British showrooms, their real-world limitations, and what Toyota’s reliability advantage means as Chinese brands gain ground in the UK.
