Apple has registered domain names related to automobiles including "apple.car," adding to speculation about the company's plans to develop a vehicle. The iPhone maker registered the domain names, which include apple.car, apple.cars and apple.auto in December, according to domain information provider Who.is.

Until now, Apple has not disclosed plans to develop a car. The company is trying to bring its CarPlay platforms to automobiles. The software platform lets drivers access contacts on their iPhones, make calls or listen to voicemails without taking their hands off the steering wheel.

Apple has been also aggressive in recruiting auto experts from companies such as Ford or Mercedes-Benz.
