Lexus has always been committed to the concept of ‘jidoka’—the Japanese word for automation—with a human touch. This is exemplified by the GX460’s V8, in which precision-machined engine components are first meticulously cleaned and painstakingly scrutinized before assembly. Further quality control testing takes place to ensure the smooth running of the crankshaft beforehand assembly at our Tahara plant. To reduce the overall engine weight, the V8 cylinder block is die-cast in a lightweight yet strong aluminum alloy. Finally, each GX460 undergoes a demanding final track test.
