The Infiniti looks like an amazing car when it comes to sportiness. A rev-happy V8 with great sound and also handling and precision to boot. 0.89g is seriously amazing for such a big and heavy sedan. Funny how these were the attributes BMW used to be known for.
Though, the 5-series overall fared better due to more comfortable ride, giving credit where it is due, great job Infiniti kicking that BMW's a** when it comes to all-out sportiness in a luxury sedan segment.
