well...well u dont know technally sorry to say bro.....ok first of all its not like 0-100,,,,, like a 30 km drag race,,,,n then 321....first VTi is faster due to more hp..but then after 100km drag comes to play n u need excessive torque to overcome drag n as a result at 100km the 316 will shoot past it as geramn dont go for hp but emphasize on torque,,,,, have a poll here and ask others what they say......japnese n americans are NO match to germans....by way have u seen tht the 1970 model diesel bmw n merc were common rails and japnese introduced it in 1999....if u look into history....germans rule techically.....tell me japnese sedan which has a V12 engine and a mighty 800Nm of torque....if u can...i'll take it for sure tht vti is better..
