BMW is committed to developing a production-viable fuel cell powertrain, and this week showed two research vehicles that it is using to develop the technology. One of them is based on the sleek i8 sports car, which has a modified body designed to be even slipperier through the air.

Jeep’s Grand Cherokee was originally due to undergo a complete redesign in 2017. However, there’s been a change in plans and now we’re hearing that the redesigned model may not be launched until 2018 or '19.

Dodge has come out with a new television spot highlighting its three main performance offerings. The ad is very slick and well worth the watch, especially the extended version.

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