Today on Green CarReports: It's all about the Frankfurt Auto Show.

We've got details of concepts and new production cars, plus a host of live galleries of the greener and more interesting cars. Meanwhile, there's a new Nissan Rogue, and Tesla is working hard to complete the expanded Supercharger quick-charging locations it promised by the end of summer. All this and more on Green Car Reports.

From Frankfurt, we have details on the redesigned 2014 Nissan Rogue just unveiled this morning.

Another crossover, shown in concept form, caused more than one jaw to drop in disbelief: the Lexus LF-NX Concept has lines so sharp you might cut yourself. It previews a production vehicle we suspect will be more restrained--but look at our photos and see for yourself.

We've got pictures of a third crossover concept, the BMW Concept X5 eDrive, which is a thinly disguised version of a plug-in hybrid X5 that will enter production within a year or two.

Then we got a look at the final production version of the 2015 BMW i8 plug-in hybrid sports coupe, to be priced at $136,000--plus we have live photos from the show floor as well.

Moving way up the supercar ladder, we've also got photos of another German plug-in hybrid sports car, the 887-horsepower Porsche 918 Spyder. Pretty, pretty thing it is, too.

Leaving Germany, we follow a German carmaker--Volkswagen--as it logs up some impressive August sales due to its TDI diesel models.

And finally, we look at how Tesla Motors [NSDQ:TSLA] is doing on opening the 18 Superchargers it promised this summer.
