We managed to spend half a day on track with the 2013 McLaren MP4-12C Spider, and it proved to be every bit as good as we expected--and then some. To find out why this convertible makes sense on track, read our report.

The 2014 Mercedes-Benz GLA Class will extend the brand's reach farther down into the compact luxury crossover segment, borrowing from the new A Class hatchback sold in Europe. How much space do you really need?

Transformers 4 is on its way, and with it, it brings a whole new cast of Autobots and Decepticons. The Bumblebee Camaro will be among them, wearing a restyled look that's especially noticeable at the nose.

You'll find all of this and more in today's car news headlines from around the High Gear Media network, right here at Motor Authority.
