2010 Renault Megane III CC Dimensions, Size & Specs

The curb weight of the Renault Megane III CC ranges from 1430 kg to 1625 kg (3153 to 3583 lbs), depending on the specific trim and equipment. The maximum permissible weight, which includes the vehicle, passengers, and cargo, ranges between 1839 kg and 2017 kg (4055 to 4444 lbs). This weight range reflects the car’s solid build and structural reinforcements typical in convertibles, balancing performance, safety, and fuel efficiency.

The Renault Megane III CC offers a luggage capacity of 211 liters (7.45 cubic feet) with the rear seats in their standard position. When the rear seats are folded, this space expands to 417 liters (14.72 cubic feet). This level of cargo capacity is reasonable for a compact convertible, allowing sufficient room for daily essentials and weekend trips, although it remains less than traditional hatchbacks due to the cabriolet design.

Yes, the Renault Megane III CC fits comfortably into a standard garage. With a length of 4485 mm (176.6 inches), a width of 1811 mm (71.3 inches) excluding mirrors, and a height of 1434 mm (56.5 inches), it is compact enough for most standard garages. Keep in mind that when mirrors are opened, the width extends to 2072 mm (81.5 inches), so it's best to fold mirrors or ensure your garage is wide enough for safe entry. This compact footprint makes parking and storage convenient for urban environments.

The Megane III CC features a ride height (ground clearance) of 120 mm (4.7 inches), which is relatively low and typical for sportier coupes and cabriolets. This low ground clearance enhances the car's aerodynamics and handling by lowering the center of gravity, resulting in improved stability and cornering performance. However, it means drivers need to be cautious over speed bumps, rough roads, or steep driveways to avoid scraping the underbody.

The Renault Megane III CC offers a variety of rim and tire sizes tailored to both comfort and sporty performance. It comes with rim sizes of 16, 17, and 18 inches. Corresponding tire options include 205/55 R16, 205/50 R17 H, and 225/40 R18, respectively. These options allow owners to balance ride quality, grip, and styling, with larger 18-inch rims typically providing sharper handling at the expense of a firmer ride.

Compared to its predecessor, the Megane II coupe and cabriolet models, the Megane III CC is generally slightly larger and heavier. The third generation measures 4485 mm in length and weighs between 1430 and 1625 kg, reflecting advances in safety and comfort features that add weight. The increased dimensions result in more interior space and improved ride comfort while maintaining a sleek profile. These changes aimed to offer a more modern and refined driving experience, though they inevitably made the car marginally bulkier.

In comparison with similar compact cabriolets from the early 2010s, such as the Volkswagen Golf Cabriolet and the Audi A3 Cabriolet, the Renault Megane III CC holds its own in size and practicality. Its length of 4485 mm positions it slightly longer than many rivals, contributing to a more spacious cabin and better trunk capacity. Although its luggage volume (211 liters to 417 liters folded) may be smaller than some hatchback-based competitors, its styling and equipment levels provide good value. With a curb weight of up to 1625 kg, it is competitively weighted for this class, balancing agility and comfort.

The Megane III CC generation was available in two body styles: cabriolet and coupe. The cabriolet features a retractable hardtop roof, which adds structural reinforcements and mechanical components, contributing slightly to the overall weight compared to the coupe. Despite this, the external dimensions between the two variants are very similar, with the main differences being in weight and trunk space, as the cabriolet’s roof mechanism reduces available luggage capacity.

The Megane III CC has a width of 1811 mm (71.3 inches) without mirrors but extends to 2072 mm (81.5 inches) when the side mirrors are opened. This wider dimension requires attention when parking in tight spots or narrow garages. Drivers should fold the mirrors where possible to reduce the width, ensuring the car can fit through confined spaces without damage. When mirrors are left open, it is important to account for this extra width to avoid collisions with walls, curbs, or neighboring vehicles.
