I''ve watched BBC's TOP GEAR this week,they test drive A4.
They said this car is the world 's first ordinary mass production car
to powered by 5V/cyl.
Toyata has this type of engine few years ago,the engine code is
4A-GE,the used engine already sent to sale in Thailand few years ago ,too.
it's cylinder head color is silver,stamped with toyota logo and the letter
"20 valve".
