Compared to M-performance versions of BMW vehicles, and AMG Mercedes-Benz models, The RX 500h is less canyon carver or straight-line muscle machine, and more grand tourer; it rides better than many of those caffeinated crossovers, and is less expensive. Lexus has struck a fine balance of sporty feel and serious luxury that premium-crossover shoppers will appreciate. The RX 500h F Sport Performance is not a compromise, but an alternative to premium crossovers that may be a little too sporty.
