Chevrolet Camaro 2011 – SS Convertible vs Ford Mustang 2011 – GT Convertible

On paper the 2011 Camaro SS convertible should beat the Mustang GT convertible without breaking a sweat, since it brings a 6.2-liter V8 and a 14 horsepower advantage to the fight. In period testing it lost anyway. The reason is a number neither brochure put on the front page. Read on to find out why 413 pounds mattered more than 14 horsepower in the battle of the drop-top pony cars.

Two drop-top V8 pony cars, one with a bigger engine and more horsepower, and the wrong one keeps winning. That is the awkward result sitting at the middle of this comparison, and it is the kind of outcome that makes a spec sheet feel like it is lying to you. One of these convertibles brings 6.2 liters and a clear power advantage. The other brings 5.0 liters and gives up 14 horsepower before the light turns green. Period testing put the smaller-engined car in front anyway, by a margin large enough that it cannot be dismissed as driver error or a good launch. So what is actually deciding this fight, and why is it not the thing both marketing departments led with?

The Power Advantage Was Real, and It Was Not Enough

Start with the engines, because the numbers are not in dispute. The 2011 Camaro SS with the manual gearbox used the 6.2-liter LS3 V8 rated at 426 horsepower, an old-school pushrod V8 with two valves per cylinder and a great deal of displacement doing the work. The 2011 Mustang GT arrived with Ford’s then-new 5.0-liter Coyote, a dual-overhead-cam, four-valve V8 rated at 412 horsepower and 390 lb-ft of torque. On raw output the Camaro wins, and on torque the Camaro wins as well.

413 Pounds Is the Whole Story

Then you weigh them. The Mustang GT convertible came in at roughly 3,725 pounds. The Camaro SS convertible came in at roughly 4,138 pounds. That 413-pound difference is close to the weight of two adult passengers riding permanently in the Chevrolet, and it wipes out the horsepower advantage and then some. In period testing the Mustang reached 60 mph in about 4.5 seconds against roughly 4.7 for the Camaro, which is exactly what power-to-weight arithmetic predicts once you stop looking only at the horsepower column.

Why the Camaro Convertible Weighs What It Does

The Camaro’s weight is not carelessness, it is architecture. The fifth-generation Camaro was built on a large rear-drive platform originally developed for full-size Australian sedans, and it was a substantial car before anyone removed the roof. Convertibles then need structural reinforcement to replace the rigidity the roof was providing, typically in the form of a strengthened floor, additional bracing, and heavier body structure, and Chevrolet added a considerable amount of it. The car is impressively solid for a convertible. It is also heavy for the same reason.

The Automatic Camaro Was a Different Car Entirely

Buyers who chose the automatic got a meaningfully different Camaro, which is worth knowing if you are shopping used. The automatic SS did not use the LS3, it used the L99, a related engine fitted with cylinder deactivation and rated lower, at 400 horsepower and 410 lb-ft. That means a 2011 Camaro SS is not one specification but two, and the gap between them shows up in both performance and how the car feels off idle.

Coyote Versus LS3, Two Philosophies in One Fight

The two V8s also represent genuinely different engineering philosophies, and that shapes how each car drives. The LS3 is a large-displacement pushrod engine that makes strong torque low in the range and feels effortless everywhere. The Coyote is a smaller, higher-revving overhead-cam design that rewards you for using the top half of the tachometer and sounds completely different doing it. Neither is objectively better, but they ask different things of the driver, and with the roof down you hear both arguments very clearly.

Visibility, and the Thing Camaro Owners Quietly Admit

There is also the visibility issue, which nearly every period review of the fifth-generation Camaro mentioned and which owners tend to acknowledge with a shrug. The high beltline, thick pillars, and shallow glass make the coupe feel like a bunker from the inside, and while dropping the top solves most of that, the car still has poor sightlines when the roof is up. The Mustang, with its more conventional greenhouse and lower cowl, is simply an easier car to place on the road.

Chassis Behavior With the Roof Down

With the roof down the handling difference follows directly from the weight. The lighter Mustang changes direction more willingly and feels less like it is managing its own mass, and period comparisons generally gave it the nod on chassis behavior and steering feel. The Camaro answers with better straight-line composure and a more planted, big-car feel at speed, which some buyers genuinely prefer for open-road cruising.

How the Two Cars Aged After 2011

A decade and a half later, both have settled into the used market and the picture has shifted in interesting ways. The 2011 Mustang GT carries real historical significance as the first year of the Coyote engine, a motor that went on to become one of the most swapped and modified V8s in the world and is still in production in evolved form. The Camaro SS answers with the LS3, an engine with an equally deep aftermarket and a well-earned reputation for absorbing abuse, and the fifth-generation Camaro has aged into being remembered more fondly than it was reviewed.

Which One Should You Buy Now

Which one to buy now depends almost entirely on what you want the car to do. If the plan is spirited back-road driving with the roof down, the Mustang’s lower weight and better sightlines make it the easier car to enjoy, and the first-year Coyote is a genuinely great engine. If the plan is highway miles and straight-line muscle, the Camaro’s extra mass works in its favor and the LS3 makes the whole thing feel effortless. On the practical side, check for the usual convertible issues on either one, meaning top mechanism operation, water intrusion at the seals, and any sign of chassis flex from a hard life. And confirm which Camaro you are actually looking at, because an automatic car with the L99 is a different specification from a manual car with the LS3 and should not be priced the same.
