The Infiniti QX50 is a solid performer. Its well-sorted steering and suspension make it a pleasure to drive.
The new turbocharged VC engine delivered as advertised. It's punchy under hard acceleration and smooth and relaxed in highway cruising. The Environmental Protection Agency expects 24 mpg fuel economy in the city, 30 mpg on the highway, and 26 mpg combined for the all-wheel-drive version. Add one mpg for front-wheel-drive models.
While the VC engine delivers the goods, it was let down by the continuously variable transmission Infiniti paired with it. The CVT simply doesn't do an effective job in maximizing the capabilities of the engine. Under hard acceleration, the CVT forces the engine to the upper end of the rev range. It's a common occurrence in transmissions of the type, but the result is a less refined feel that's unbecoming of a vehicle of the QX50's genre. In addition, others such as the Subaru Ascent proved you can pair a turbo-four-cylinder with a CVT in a large SUV and have it not sound like an underpowered economy car when you floor it on an on-ramp.
