 | | Straight-six engines were historically more common than V6's, mainly because the length of such engines was not such a concern in rear-drive vehicles but also because V6's (unlike the 90-degree V8) were somewhat difficult to make smooth-running. |
 | | Jaguar used them, from 1949 untill the mid 1990s in form of the legendary twin cam Jaguar XK6 engine, until, reputedly at Ford's insistence, they adopted a V8. |
 | | Toyota started with their M-series engine and later the F, FZ, G, and JZ engines, and Datsun started with their H-series and later the L and RB engines. |
