Why it stands out
The 2020 INFINITI QX80 distinguishes itself as a luxurious full-size SUV, leveraging its refined features and spacious interior to create an appealing option for buyers looking for both comfort and capability. This model has received notable updates over previous years, enhancing its premium feel with modern design elements and a refreshed infotainment system, despite some lingering outdated technology. Powered by a robust 5.6-liter V8 engine that produces 400 horsepower, it offers strong performance as well as a comfortable ride thanks to its advanced suspension system. The QX80 also boasts a variety of standard features, including tri-zone climate control and an intuitive infotainment setup, catering to both driver and passenger needs. While it excels in luxury and power, potential buyers should consider its less-than-stellar fuel economy, making it a trade-off between performance and efficiency.
