2023 Mercedes-Benz SL-Class SL 63 AMG

This is Mercedes-Benz's two-door convertible flagship, the SL, a grand tourer that trades a back seat for open-air luxury. It's a car that feels equally at home on a winding mountain road and a long interstate cruise, with sharp steering and a supple ride. Inside, the cabin wraps you in leather and tech, with a portrait touchscreen and a neck-level heating system that makes top-down driving comfortable in cooler weather. Expect premium running costs, from fuel to service, but the SL's blend of performance and prestige holds its value well. The SL 63 swaps the SL 55's V8 for the handcrafted biturbo 4.0L V8 and adds active hydraulic roll stabilization and rear-axle steering as standard. That biturbo V8 and the nine-speed automatic with a wet clutch deliver brutal acceleration, and the all-wheel drive hooks up hard enough to make the 577 horsepower feel usable on real roads. The active roll stabilization keeps the convertible flat through corners without punishing you on the highway, so it rides better than a track-focused car while still being one.
