A prototype for Audi’s next-generation RS 4 has been spotted. It’s rocking the A4’s wagon bodystyle which suggests the car will once again skip the United States. We hear that Audi may launch an RS 5 Sportback here instead.

Another Audi we’re unlikely to see locally is the new A8 L Extended. It’s a 21-foot A8 with six doors and six seats, and right now there’s just one in existence.

Tesla Motors [NSDQ:TSLA] has opened up its online configurator for the Model X to everyone. Previously, only those with deposits could go online to set up their ideal version of the high-riding electric hatch.

You'll find all of these stories and more in today's car news, right here at Motor Authority.
