Toyota RAV4
Toyota designed the original RAV4 before the term SUV became widely known so it had to come up with its own name. RAV4 means recreational active vehicle with four-wheel drive, though the model comes standard with front-wheel drive in most markets.

Toyota Corolla
You won’t find a picture of a humble economy car if you look up the word corolla in the dictionary. Instead, it’s a noun defined as “the petals of a flower, typically forming a whorl within the sepals.” It’s a term commonly used by botanists

Tesla’s first car was quite simply called Roadster. The California-based company then launched a new naming system when it introduced the Model S (pictured). It later released the Model X, the Model 3 and Model Y. SX3Y, then.

Tesla originally wanted to name its entry-level car Model E but Ford threatened to sue because it owned the rights to that name. Replace 3 with E and re-arrange the letters in Tesla’s line-up to discover what the company’s naming system leads to

Porsche 911
Flashbulbs popped as Porsche introduced the brand-new 901 at the 1963 Frankfurt auto show. Sleek and powerful, the 356’s long-awaited successor made headlines all around the world but it caught the attention of Peugeot for a completely different reason. The French firm swiftly reminded Porsche that it owned the rights to every three-digit car nameplate with a zero in the middle. And, though it didn’t plan on releasing a model named 901 and it certainly had no intention of building a rear-engined sports car, it wasn’t about to let Porsche get away with trademark infringement.

Porsche replaced the zero with a one to create the 911. It made about 82 901-badged pre-production cars before changing the car’s name. It's fair to say the 911 hasn't looked back.
