The Lexus GS goes up against some of the best cars on the market, the mid-size luxury cars from Europe and the U.S., and acquits itself well.
BMW’s 5-Series is brand new; its turbo-6 is a much stronger engine than Lexus’ naturally aspirated V-6, and it’s turbo-4 is stronger than Lexus’ version.
The Mercedes-Benz E-class is also new, and it is the benchmark for interior elegance and luxury.
The E-Class also offers a vast array of models and body styles.
Audi’s A6 is aging, and we prefer its coupe-like A7 sibling.
Still, its supercharged V-6 is strong, it offers lots of cachet, and it has plenty of tech features.
The Cadillac CTS is a great entry from America.
We like the styling and the Caddy takes a backseat to no rival in terms of handling.
The Infiniti Q70 is is similar to the GS with its V-6 power and Japanese roots, but it has a coarse engine and Infiniti lacks the prestige of its rivals.

The 2018 Lexus GS is a worthy rival to its German foes in terms of luxury and handling, but its engine lineup is falling behind the competition. |
The 2018 Audi S6 stands with an impressive hand: quality interior, great performance, functional shape. It's possible to find better examples from other cars, but they all cost significantly more. |
The 2018 BMW 5-Series expands the sedan's already-excellent lineup to include an efficient plug-in hybrid and an uber-quick V-8. |
The 2018 Cadillac CTS-V scorches the earth, and leaves the E63 and RS7 with some burn marks. |
The 2018 Infiniti Q70 stands alone as a warm take on luxury that others have left behind. It’s not as luxurious as the others—but it’s not as expensive as those, either. |
The 2018 Mercedes-Benz E-Class goes to excess--the right kinds of excess--to preserve its best-of status. |
