YES.

Engineer Division: Here is a wonderful design we've come up with, maximizing all the technologies we have available to us to show what can be done if we all work together
Boss: Well I certainly like the price. Do you think you can replace all those different materials it is made of with iron and that plastic we use on our existing crap. And replace the engine with a standard 1.6 DOHC and remove the batteries. But keep the shape, because it looks futuristic.
Engineer Division: But,..
Boss: Performance review in a month. Choose your next words wisely
Engineer Division: Yes sir
Marketing Department: We can call this one the Zoomster, because it looks fast
Boss: Excellent. Make it so.

I think that is not only green but also way cool. I wonder how much of that technology will make it into everyday cars. I think it would be cool to have a car that looks great and gets really good MPG.

Concept car gets 235 mpg and is so light it needs to be tethered to keep it from floating away.
Production model lauded for getting 42 mpg and cracks cement as it rolls down the highway.

for a few thousand dollars or less + a few days of work, and some training----once can modify an old geo metro from 30 years ago, put a couple add ons such as those noted on noteable 'hypermiling websites'.
then you spend a few days training how to drive properly for efficiency optimization, and you can get over 75 miles a gallon.
the future of fuel efficiency is in onboard computers the either drive the car for you, or modulate the existing manned driver's driving to ensure the car's acceleration and deceleration profile is optimized for fuel efficiency.
the key to fuel efficiency is not hard acceleration /deceleratoin and as much 'gliding' as possible --coasting downhills in neutral and even stop starting the vehicles engine to 'pulse' the motors input to the wheels.
that takes effort to learn, but a car computer could be optimized to modulate a drivers input to the pedals/breaks and shifters in order to achieve this.
in the real world-------------where price is everything-------none of the above accommodations will be innovated or sold. they are useless.
in the real world, if you simply raise gas taxes, more efficient cars will be purchased by consumers, and they will also drive less, moving their housing choices to cities, where walking biking public transit and car sharing/renting/pooling are feasible
in the u.s. gas taxes aren't going up because the oil companies own the country. electricity prices are going up because the oil companies are scared of electric cars and electric everything. they've convinced the public to try and put coal and nuclear and natural gas out of business by raising electricity prices wholsale. wall street's enron model---buying power companies to shut them down and raise rates-------is now fully legalized and practiced openly by the likes of goldman sachs passing for 'environmentalism'.
the more things change, the more they stay the same.

Somewhat deceptive to just call this a hybrid when it is a plug-in hybrid. You would only get that efficiency for a short distance.
Without a pillar between the doors this would kill a lot of passengers in side impacts. What does it mater though, it is just the wife and kids getting killed. Totally replaceable. :(
If safety is eliminated, efficiency can go up, but who wants to drive a death trap?
Add enough carbon fiber in the doors and maybe, but it seems more efficient to just have a carbon fiber pillar. What's that, another 5 pounds?
I hate that every car company wants to patent every efficiency gaining feature. That effectively limits its adoption. Tesla on the other hand opened up its patents for others to use without charge. Where are the other makers following its lead?
I will never believe a company really cares about the environment until they make their efficiency innovations available to other makers. We can't wait another 18 or 20 years for ideas to become available.

Interesting tech, and it looks good as well. Bravo Renault.

My personal experience with Renault cars is that they were junk that decomposed and fell apart daily. I would like to be an optimist but frankly i have zero confidence in anything built by Renault.

This is all great but I want to see the actual crash test results.

You'd think that somewhere in an article that focuses almost 100% on weight savings that the actual weight would be listed.
