Why it stands out
The 2018 INFINITI QX80 stands out in the luxury SUV segment as a well-rounded choice that emphasizes comfort and advanced features. This model provides a smooth ride complemented by a spacious interior filled with premium materials, making it particularly attractive for families or those who seek comfort during long drives. One of its key strengths lies in its impressive safety features, which contributed to its earning a Top Safety Pick+ Award. While some may find fault with its less-than-ideal fuel efficiency—often noted as a gas guzzler—the value proposition remains strong, especially considering its luxurious specifications.
