The Shelby GT350 and GT350R will attract buyers no matter what they weigh in at. That's what happens when you sport a 5.2-liter V8 good for 526 horsepower. We've learned a lot about these new Mustangs over the past few months, and now we know a bit more. The curb weights for the GT350 and GT350R have just been released. The GT350 comes in at 3,760 pounds and the GT350R is in at 3,650. So, how do these weights stack up to the rest of the lineup?

At 3,760 pounds, the GT350 is lighter than the current crop of GT models - as in the 5.0-liter V8 non-Shelby GTs - save for one. The manual GT fastback barely beats it out at 3,705 pounds. The GT350R does quite well with its 3,650 pounds. It's lighter than all of the aforementioned GTs and even skinnier than the V6 EcoBoost convertible. This lightweight comes at a price, as the GT350R doesn't feature such creature comforts as backseats, air conditioning, a backup camera and radio. The GT350's chief competitor will be whatever top-line Camaro is rolled out, and unless the weight is drastically higher or lower, how hefty either car is likely won't matter.
