How much did a 2009 Ford Mustang GT convertible with manual transmission weigh
Executive summary
A 2009 Ford Mustang GT convertible is commonly reported to have a curb weight around 3,461 pounds in factory-trim listings for that model and body style, a figure repeated by multiple car-spec aggregators and reviews [1] [2]. Some community discussion and scattered sources claim slightly different numbers—most notably around 3,540 lb for certain transmission configurations—but authoritative, consistent factory documentation tying a specific manual-transmission convertible to a different curb weight is not present in the provided reporting [3].
1. The headline number: 3,461 pounds for the 2009 Mustang convertible
Several widely cited spec pages and mainstream car-review aggregators list the 2009 Ford Mustang convertible’s base curb weight as 3,461 pounds, a figure that appears in TheCarConnection’s 2009 Mustang specification summary and in Car and Driver’s listing for the 2009 Mustang convertible trim [1] [2]. These sources present the 3,461-lb figure as the base curb weight for the convertible body style, which is the most directly comparable published number available in the provided reporting [1] [2].
2. Where the confusion about manual vs. automatic transmission comes from
Online forums and user threads amplify uncertainty: one thread asserts that 3,540 pounds was the weight for the automatic-transmission Mustang and that sources have misattributed that to manual-equipped cars, but the post acknowledges the author could not find verification on Ford’s site and frames the 3,540-lb figure as a belief rather than confirmed factory data [3]. That community-sourced claim highlights how enthusiasts’ memory, aftermarket modifications, and different trim/package combinations can seed conflicting numbers even when published spec sheets exist [3].
3. Coupe vs. convertible: an important distinction in published weights
Published data show variation by body style—Car and Driver’s spec pages for the 2009 Mustang coupe and convertible list different base curb weights (the coupe commonly quoted at lower figures such as 3,336 lb in some compilations, while the convertible appears at 3,461 lb), demonstrating that the top and its associated structure add appreciable mass and that comparing coupe and convertible numbers without noting body style inflates confusion [4] [2]. Industry spec aggregators and magazines usually separate these figures by model/trim and thereby provide the most reliable baseline when determining curb weight for a specific configuration [1] [2].
4. Secondary spec sites and catalogues largely corroborate but vary in detail
Other spec collectors—CarBuzz, Automobile-Catalog, LMR and Edmunds—publish detailed technical sheets and advertorial pages for the 2009 Mustang GT and generally align on engine, power and trim descriptions but do not always present a single, uniform curb weight number for the GT convertible with manual transmission in the provided excerpts, underscoring why aggregation sites like Car and Driver and TheCarConnection become default references for the convertible’s baseline weight [5] [6] [7] [8]. When sites do list weights they sometimes label them generically as “base curb weight” without breaking out transmission-specific differentials, leaving small but potentially meaningful ambiguities [1] [2].
5. Conclusion and reporting limits: best-available answer and caveats
The best-supported published figure in the provided reporting for a 2009 Ford Mustang convertible is a base curb weight of approximately 3,461 pounds, and that number is the most defensible single-point answer here based on TheCarConnection and Car and Driver listings [1] [2]; however, community posts and scattered references that cite ~3,540 lb or other weights for particular transmission or option combinations exist but are not corroborated by the factory or by an authoritative Ford technical sheet in the supplied sources, so they remain plausible but unverified in this set of reporting [3]. If a transmission-specific factory placard or Ford dealer spec sheet is required for absolute confirmation, that document was not included among the provided sources and therefore cannot be quoted here [3].
