At first glance, those four objects on the photo seem to look like new-age mobile phones, and while we can’t fault you for thinking that way – they do look like mobiles from a distance – those are actually four concept vehicles Renault is planning to unveil at the Frankfurt Motor Show.

Say what?

Of course, the bird’s eye view of the cars doesn’t really help in deciphering what they really are, but take our word for it, those are Renault->ke72’s new electric concepts.

It’s an odd way to show images of the car really because it leaves room for a lot of speculation as to what these cars really look like. But maybe that’s exactly what Renault is aiming for.

The first – and smallest – one looks like a one-seater. The second one looks like a three-door compact car that has a glass roof on it. The third one, which is slightly bigger than the second car, looks like a five-door vehicle that can fit around four to five people while the last one – the biggest among the group – looks more and more like a sedan.

We told you it was hard to figure these cars out. But the good news is we don’t have to wait long to catch a glimpse of these four Renault electric concepts. The cars are ser to be unveiled in a press conference scheduled on September 15 at 10:45am GMT. Renault CEO Carlos Ghosn will be on-hand for the presentation as surely he’d be the best person to help us introduce the vehicles.

In any event, here`s the press release for your perusal.
