Concept cars always promise the car of tomorrow, but they only get us hot and bothered for fantastical design elements that rarely make it to production due to trivial concerns like "cost" and "the laws of physics." Undaunted by these limitations, Nissan has rolled out a new futuristic EV called ESFLOW -- with a roofline inspired by modern Z cars and an elongated bonnet reminiscent of the original 240Z -- to titillate our inner gearhead. Scheduled for a Geneva Motor Show debut in early March, the coupe is powered by children's dreams and whimsy dual electric motors driving the rear wheels and can take residents of imagination land from 0-100kph (0-62mph for us Yanks) in less than five seconds. If the ESFLOW is where Nissan's going with its EV designs -- the Leaf isn't exactly a looker -- we're all for it, but don't expect to see it on the road anytime soon as it's only a concept after all. Vid's after the break.

Putting the spark into electric vehicles
It may be a concept, but the Nissan ESFLOW electric sports car proves it's possible to remain environmentally sympathetic without having to give up the joy of driving.
It looks like a sports car, handles like a sports car and performs like one too. Using technology pioneered in the award-winning Nissan LEAF, the EV concept shows that driving can still be as much fun tomorrow as it is today.

The Nissan ESFLOW
Nissan has a reputation for creating some of the most exhilarating sports cars on the market. Nissan has also developed the world's first practical Zero Emission family car, the Nissan LEAF.
Now Nissan has put that expertise together. It has captured the excitement of a sports car and the environmental benefits of an electric vehicle and blended them into one dramatic two-seater concept: ESFLOW.
ESFLOW has been created from the ground up as a pure electric vehicle, to give an idea how a Zero Emission sports car of the future might look. Living ecologically has often been seen as an act of austerity - to save one's environmental conscience sacrifices must be made. ESFLOW is here to address that misconception.
Owning an ecologically sound car does not have to come at the expense of driving enjoyment. The briefest glance at the ESFLOW is enough to tell you what kind of car it is: a long bonnet leading into a steeply raked, wrap around windscreen, the compact cabin placing the occupants bang on the car's centre of gravity, hunched arches over ultra-low profile tyres wrapped around six spoke wheels. ESFLOW is unmistakably a sports car, and those in the know will recognize its heritage - hints of classic and contemporary Nissan sports cars abound.
Vitally, ESFLOW is not an existing ICE (internal combustion engine) powered vehicle that has been adapted to run on electricity, but a sports car that's been designed from the outset as a Zero Emission vehicle. This means that Nissan's forward thinking designers have had free rein to place the power train and batteries in the optimum positions to benefit the car's handling and performance and enhancing the thrill of driving.
The Car
The ESFLOW is based on existing technology, implemented in innovative ways. An attractive, head turning composite body covers an aluminium chassis, incorporating its own roll cage. The powertrain unit, which employs the same technologies installed in the Nissan LEAF, is tuned to offer a sporty driving experience.
The Powertrain
ESFLOW is rear-wheel drive and it runs on two motors. The car's graceful proportions allow the twin electric motors to be placed above the axis of the rear wheels, in a mid-ship position,. These motors independently control the left and right wheels, and so the torque is optimized to ensure outstanding vehicle stability and control as well as efficient power regeneration. The motors produce enough torque in an instant for it to reach a 100kph in under 5 seconds.
Power for the motors comes from the same laminated lithium-ion battery packs used in the Nissan LEAF, but in ESFLOW the packs are located along the axis of the front and rear wheels. This centralizes the mass of the car, and thus its rotation point, close to the driver's hips. These cleverly positioned batteries enable the car to travel over 240km on one charge.
The Chassis
An aluminium chassis has been built around the drive train, taking full advantage of the opportunities that Zero Emission electric propulsion provides. Power cells are incorporated in such a way that they benefit ESFLOW's strength and poise, not detract from them. Indeed, unlike a conventional fuel tank, batteries do not get lighter as they provide energy, so the car's weight distribution remains constant throughout a drive.
The high waistline afforded by the ESFLOW's classic sports car proportions allows strong, yet unobtrusive roll bars incorporated in to the structure behind the seats to safely take the entire load of the car in the event of a roll over, negating the need for obtrusive, thick, reinforced A-pillars and the blind spots they inevitably create.
This almost unobstructed view ahead will not be unfamiliar to fighter pilots, and just as such pilots speak of "strapping their planes on to their backs", we hope ESFLOW owners will also feel the car to be an extension of their bodies, reacting to their slightest whims. The driver must be at the centre of the sports car both physically and metaphorically.
The Body
The ESFLOW is undoubtedly an attractive car. Crisp, clean lines not only convey the purity of its sporting potential, but suggest the clarity of electric power. The colour scheme chosen for the concept car is inspired by glaciers - highly reflective solidified liquid with blue tints in its shadows. Like its ZEV concept forebears and contemporary stable mate the ESFLOW's headlights and Nissan emblem are tinted cool blue. The six spoke wheels contain blue carbon inserts while the same material adorns the side sill, roof mounted lip spoiler and lower rear bumper.
Blue LEDs accentuate the futuristic lights slashed into the bodywork both front and rear. Where the Nissan LEAF's protrusive headlights are used to guide airflow around the door mirrors, this is not needed on ESFLOW as the mirrors have been replaced with minute rear view cameras at the base of its A-pillars. The ESFLOW's front lights do protect a secret of their own however: flip out charging points built in to the air ducts beneath.
The Interior
Ecological minimalism need not come at the expense of luxury. The cabin of the ESFLOW is clean and open and weight saving has been a priority throughout its design, but it is still a comfortable and pleasant place to sit. By far the heaviest components in modern cars' interiors are the steel framed, thickly upholstered and increasingly motorized seats. In ESFLOW the seats are sculpted into the rear bulkhead of the car, negating the need for a heavy frame. This of course means that they are immobile, but this is of no consequence as the fly-by-wire steering and pedals adjust electrically to the best spot to suit each individual driver's size and preferred driving position.
The seats themselves are upholstered in gold leather and perforated gold suede while the doors are trimmed in dark blue leather and suede. The blue and gold motif, the colour of sparks, is continued across the dashboard, which is also adorned with silver carbon trim, and features four multifunction illuminated LCD displays.
The Driver
Daniel, an ESFLOW owner, works in tech, but lives for the weekend. On Friday night after work, he gets behind the wheels of his ESFLOW which instantly links with his pocket PDA and determines the fastest route to his girlfriend's home. Finding street side parking is a synch as the ESFLOW's compact dimensions allow it to slip in to the narrowest of spaces. On Saturday he drives to a popular club to exhibit his DJ skills and his friends are impressed by his cool EV sports car.
On Sunday he drives through the mountains for leisure. ESFLOW's superb weight distribution and unobstructed view ahead enables him to effortlessly nail every apex, every time. His descent from the mountains is more relaxed and he allows the ESFLOW to overrun on the long sweeping curves, turning the potential energy he and the car gained climbing up the gradients back in to electrical energy he can use once he hits the roads around Barcelona.
As his ESFLOW sips energy in its garage Daniel prepares himself for the week ahead, batteries fully recharged.

After seeing many atrocious attempts, it seemed factory iPad integration was something that simply shouldn't happen. Now, in Volkswagen's Bulli concept, we're seeing something that makes sense -- something we've wanted to see for a while now. The tablet sits in a custom cradle in the center of the dash, extended on a pivoting arm so that it can turn toward driver or passenger. It then provides center stack duties, letting front-seaters manage the climate controls, play some music, and of course get directions. Naturally we'd like to see something a little more platform-neutral if it's going to be a factory option, but we're guessing that if indeed this new-age Vanagon ever sees production its interior will look nothing like this anyway. So, no point in getting too worked up about it, then. 
We've got some good news and some bad news for folks eager for a sportier, all-electric Smart vehicle. The good news is that parent company Mercedes-Benz has just taken the wraps of its brand new Smart Forspeed concept vehicle, which will make its debut at the upcoming Geneva Motor Show. It's a compact, all-electric roadster that promises a top speed of 75 miles per hour, a range of 84 miles on a charge (which, incidentally, can be done using a normal 220 volt socket), and a luxury interior that even includes a special smartphone housing. The bad news? The company is saying up front that it "won't make production," but that "elements of the car will be carried over into future projects." Hit up the link below for a closer look.
Who says dreaming doesn't pay? A young designer by the name of Heikki Juvonen recently won himself a six-month job placement at Citroen's PSA Design Centre in Paris after producing the most compelling response to the company's Double Challenge set to students at London's Royal College of Art. The premise was simple -- put together an aesthetic for an ultra-compact urban vehicle that Citroen could call its own, and judging by the imagery above, we can all probably agree that Heikki achieved a very distinctive look with his E-3POD. We're not yet certain how we feel about being inside the largest of the three wheels for the duration of our electrically powered journeys, but the young gent has half a year on his hands to tweak and refine his eye-catching design. We'll be ready to test-drive the prototype as soon as Citroen becomes mad enough to build one.
