The Infiniti family includes several vehicles that combine luxury and performance. This is the case with the QX70, formerly known as the FX, whose base version comes with a 325-hp 3.7L V6. But since it is human nature to always want more, Infiniti is also offering a 390-hp 5.0L V8. In both cases, it has a seven-speed automatic gearbox. Even though the original FX launched several years ago, its lines are still fashionable!
