We hooked up a 2,500-pound Checkmate runabout to the FX45 and hustled to 60 mph in 10.7 seconds and halted from 60 mph to 0 mph in 174' without help from trailer brakes. At the launch ramp, the full-time all-wheel drive pulled out the loaded trailer with no slippage. The FX45's firm chassis calibrations are excellent at resisting tugs and shoves from behind, and side winds, winding roads, and rough pavement are taken in stride. The steering is confidence inspiring, and the cabin mood is serene with little or no wind or engine noise disturbance. However, when this crossover runs bareback, its tight shocks and stiff springs rattle occupants over bumps and expansion joints. The sports car genes of the Nissan 350Z are great for speed, handling, and boat towing but make for a rough ride when you're more in the mood for cruising.
