Here are some contenders:
* The "Rolls-Royce Phantom Drophead Coupé" is pretty long, coming in at 28 letters.
* The "Mercedes-Benz S-Class Cabriolet" is another contender at 28 letters.
* The "Porsche Panamera Turbo S E-Hybrid Sport Turismo" is a mouthful at 37 letters!
However, some cars have even longer names when you consider full model designations:
* The "2023 Toyota GR Supra 3.0 Premium" is 31 letters.
* The "2023 Chevrolet Corvette Z06 70th Anniversary Edition" comes in at 47 letters!
Ultimately, it depends on what you consider a "name" and how you measure length. There's no single, universally agreed-upon answer.
