(November 3, 2015) LAS VEGAS — Mazda revealed two design concepts today at the SEMA Show in Las Vegas, based on its all-new 2016 MX-5 Miata — MX-5 Spyder and MX-5 Speedster — demonstrating two vastly different takes on lightweight, open-air performance.

Lightweight. Fun-to-drive. Roadster. Those three tenets have served as the foundation for the Mazda MX-5 Miata since its 1989 introduction and continue to serve the new fourth-generation model. Focused, lightweight engineering is a guiding principle of every Mazda vehicle made with SKYACTIV Technology, allowing for greater efficiency, improved performance and agile handling dynamics.

(November 1, 2015) ATLANTA — Porsche is conducting a recall of 58,881 Macan S and Macan Turbo vehicles around the world, of which 21,835 are in the United States and 3,490 are in Canada. The reason for this move is a possible leak in the low-pressure fuel line inside the engine compartment.

The line will be replaced in the workshop. Porsche says this is a purely precautionary measure, as there have been no reports of accidents or injuries as a result of this concern.
