Starting at around $45,000, the XTS competes with midsized luxury sedans from European manufacturers like BMW, Audi and Mercedes. The XTS offers more interior room and cargo space, however, and the availability of a 3.6L, 410-horsepower turbocharged V6 means the XTS holds its own when it comes to performance. Available all-wheel-drive increases practicality and fits well with the impressive array of technologies available on the XTS.
