The Infiniti QX50 has an all-new, innovative engine and a roomy, quiet, and well-furnished interior. But the engine doesn’t provide the promised performance or fuel economy gains, and the controls are confusing to use, all of which combined to leave us underwhelmed.
This SUV is the replacement for the EX, which was renamed the QX50 in 2014; It’s now a more competitive option among luxury compact SUVs.
This new SUV sports a novel variable-compression turbocharged engine. We noted quick acceleration from a stop, with hardly any turbo lag. But in more demanding situations, the CVT lets the the engine rev very high for far too long, which in turn becomes annoyingly loud. The QX50’s 22 mpg overall in CR's testing is below its key competitors, and Infiniti’s own fuel-economy claims of 26 mpg combined. Plus, it requires premium fuel.
