Looking for a useful SUV crossover but don’t want the hiking boot look? Infiniti brings fastback design to its new 2022 QX55. It gives up a small amount of practicality to its fraternal twin QX50 but its sleeker profile is happy to help with the chores. The raked rear end joins similar silhouettes from Audi, BMW and Mercedes, just remember that Infiniti did it first with the FX35/45. Tom Voelk checks out a top trim Sensory model with standard all-wheel drive, the world’s first production variable compression engine and a steer by wire system.
