Even if the typical Lexus driver is not interested… Are there differences between American and European hybrid versions in engine/gear or other technical features?I noticed the following in various tests:European version: 0-100km/h: 6.6 – 6.9 seconds, tested: Lexus LS600h Tester: AMS, Autozeitung,… 0-100km/h: 5.9-6.5 seconds, tested: GS450h Tester: AMS, Autozeitung,…American version: 0-60mph (94km/h): 5.4 – 5.5 seconds, gete stands: Lexus LS600hL 0-60mph (94km/h): 5.5 seconds, tested: Lexus GS450h Tester (both): Car and Driver, Road and Track I know, mph != km/h , but the 6km/h from 94 to 100km/h should be over in the milli-second range rather than in the tenth-second range with a stepless transmission. Where do these (partly quite drastic) differences come from? Measurement tolerances? Vehicle differences? Test driver- Skill or not able?
