Top-Rated 2013 Convertibles:Initial Quality

Jeff Youngs | Jun 19, 2013
The annual J.D. Power Initial Quality StudySM serves as an industry benchmark for new-vehicle quality. Each year, the market research company surveys new-vehicle owners who have owned their new car for at least 90 days, and measures what has gone right and what has gone wrong during that first three months of ownership, including vehicle system malfunctions, vehicle system breakdowns, and vehicle systems that are hard to use and understand. Listed below, in alphabetical order, are the convertible models that receive the top ratings in the 2013 IQS.

2013 Chevrolet Camaro

A new Camaro ZL1 Convertible joins the Camaro LT and Camaro SS for the 2013 model year, equipped with a 580-horsepower, supercharged 6.2-liter V-8 engine and several performance-enhancing upgrades. Additionally, the 2013 Camaro Convertible is offered with Chevrolet MyLink smartphone pairing technology and a color touch-screen infotainment display. Chevrolet says it takes less than 20 seconds to drop the Camaro's top.

2013 Ford Mustang

Ford offers the 2013 Mustang Convertible in V-6, GT, and Shelby GT500 model series. This year, the GT model makes a little bit of extra power, while the Shelby GT500 makes a lot of extra power. A new 662-horsepower, supercharged, 5.8-liter V-8 engine is installed under the Shelby's bulging hood, and Ford has reworked this car's mechanicals to handle the added muscle.

2013 Mazda MX-5 Miata

Subtle styling revisions, minor trim modifications, and a new Club trim level accompany the MX-5 Miata roadster into the 2013 model year. The Club model sits between the base Sport and leather-equipped Grand Touring variants, providing an autocross-ready appearance. All Miatas have a 167-horsepower, 2.0-liter 4-cylinder engine and a manual gearbox driving the rear wheels. Get the optional automatic, and power output drops to 158. A compact, lightweight, power-retractable hardtop is optional.

2013 Porsche 911

One year after a complete redesign for 2012, the 2013 Porsche 911 Cabriolet returns with new Carrera 4 and 4S variants equipped with all-wheel drive and a wide-body appearance. Active Cruise Control and Porsche Active Safe technologies also debut for 2013. A 350-horsepower, 3.4-liter 6-cylinder engine is standard for the 911 Cabriolet, while all versions with an "S" get a 400-horsepower, 3.8-liter 6-cylinder power plant.

2013 Porsche Boxster

For 2013, Porsche completely redesigns the Boxster for the first time since the 2-seat roadster debuted in the 1990s. The new Boxster is lighter but larger, more powerful yet more fuel-efficient. Despite producing up to 315 horsepower, the Boxster S gets an EPA-rated 30 mpg on the highway. Numerous mechanical and technological improvements accompany the Boxster redesign, and the convertible top opens or closes in just 10 seconds, according to Porsche.

2013 Smart Fortwo

The 2013 Initial Quality Study adds a new City Car category, and the 2-passenger Smart Fortwo is the top-ranked model in the segment. The Fortwo Cabriolet is available in the top Passion trim level, powered by a 1.0-liter 3-cylinder engine that generates 70 horsepower. Tucked behind the two seats and under the floor of the car, the gasoline engine can be swapped out for an Electric Drive powertrain providing up to 60 miles of driving range on a single charge, Smart says.
