Is the higher price of the Audi RS 6 justified by its utility over the Lexus LX?

While the RS 6 costs $24,700 more, it provides nearly triple the usable space, boasting 29.9 cu ft of cargo capacity compared to the LX's restrictive 11 cu ft. This suggests the Audi targets performance enthusiasts who occasionally need practicality.

Which vehicle is better for long-distance, stress-free cruising?

The Lexus LX, despite requiring premium fuel like the Audi, delivers better efficiency at 22 MPG highway versus the RS 6's 21 MPG highway. Furthermore, the Lexus's more traditional SUV dimensions might appeal to those prioritizing interior space volume over outright performance.

How do the transmissions and drivetrain philosophy differ?

The Lexus utilizes a robust 10-speed automatic paired with a four-wheel-drive system optimized for varied terrain. In contrast, the Audi employs an 8-speed automatic with an all-wheel-drive setup heavily biased towards on-road handling and high-speed stability, perfectly complementing its supercar-level horsepower.

Given the power difference, how much worse is the Audi's fuel economy?

The Audi RS 6 burns fuel significantly faster to achieve its performance figures, netting only 16 MPG combined. The Lexus LX maintains a more reasonable 19 MPG combined rating, meaning commuters will visit the premium fuel pump less frequently.
