Let’s talk objective real world data to see if your assumption is true.
Here are fairly recent MotorTrend reviews of LC and LX.
LC:
2016 Toyota Land Cruiser First Test Review - MotorTrend
LX:
2016 Lexus LX 570 First Test Review - MotorTrend
Pay attention to MT Figure Eight numbers. LC has
significantly better time in the Figure 8 test than LX.
(Lower time is better)
Lexus LX: 28.2 sec @ 0.61g.
Toyota LC: 27.8 sec @ 0.61g.
And just so everyone understands what Figure 8 test means:
“The Motor Trend Figure Eight -- our signature testing procedure -- provides for a unique handling analysis. Run on the outside of two 200-ft diameter circles, the test essentially makes for a portable road course. It throws test subjects into handling extremes; in a given run, a car travels from full-throttle acceleration to full braking and then must transition into a constant-radius turn.
Out of the test come three scores: Time, average g-force, and lateral acceleration. The first is the fastest lap time from a given set of runs. The second number represents the combined average g's the vehicle creates from acceleration, braking, and cornering forces. The lateral acceleration, also measured in g-force, is the more traditional road holding measurement you would expect from a skidpad.
These three numbers, when compared, provide a stronger picture of a given vehicles handling characteristics.“
