Overview

Competing in the midsize convertible segment, the 2014 Mercedes-Benz SL-Class convertible is a direct competitor to the Audi R8 Spyder and the Porsche 911 Carrera Convertible. The Mercedes-Benz SL-Class Convertible starts off at an MSRP of $106,700 with a single trim in the lineup. Each trim is offered with a 4.7L twin-turbocharged V8 engine and a standard 7-speed automatic transmission, producing 429 horsepower, and 516 lb-ft of torque. Through this powertrain, the Mercedes-Benz SL-Class Convertible manages a 0-60 of 4.4 seconds and a combined fuel economy of 20 MPG.

Buying Advice

With its beefy price tag, the SL550 trim comes with a lot of high-end equipment. We recommend pairing it with the available Driver Assistance package for adaptive cruise control, lane-keeping assist, blind-spot assistance, and a collision mitigation system with automatic braking.
