Based on the Tata Nano platform, the Nano EV is expected to expand the company’s portfolio of electric vehicles, which has the Tata Indica Vista EV.

The electric Nano is capable of carrying four individuals. It has several design changes to reduce its mass, including a polycarbonate rear-hatch window.

Tata said it will offer a predicted range of up to 160 km (100 miles) and an acceleration of 0-60 km/h (36mph) in less than 10 seconds.

To compare, the Tata Indica Vista EV has a range of up to 200 km (124 miles) and acceleration of 0-60 km/h (36mph) in less than 10 seconds.

Tata continues its approach with the Tata Nano EV, using super polymer lithium ion batteries, as in the Tata Indica Vista EV, which provides superior energy density to conventional batteries.

The company has already displayed the Tata Nano Europa at last year’s Geneva Motor Show, and expects to launch it in select European countries in a couple of years. Meanwhile, in India, the Tata Nano, now being delivered to the first 100,000 chosen customers, has received rave reviews.

The car was originally unveiled at the Geneva Motor Show last year as a joint project between NLV and Swedish supercar maker Koenigsegg.

In order to cut as much weight as possible, the car has used a carbon-fiber monotube backbone chassis and a proprietary power storage system called Flow Accumulator Energy Storage (FAES). The FAES system has been developed by NLV themselves, weighing in a total of about 450 kg.

NLV claims the FAES system can be charged to full capacity in 20 minutes and give the vehicle a range of about 300 miles.

The NLV Quant is coated with a thin film made of pyrite, which converts light into electricity to supply the operating electronics and also help to extend the range.

Power comes from four electric motors (one for each wheel) with some type of torque vectoring software to maximize traction. There are two different power systems on board.

The body of the Quant measures in at 16 feet in length, features a pair of gull-wing doors to provide easy access to all four passengers. Interior features include multiple infotainment display screens, tri-zone climate control, and LED detailing.

Though their current relationship with Koenigsegg is unclear, NLV says they should have a running prototype up this year, with a full production model slated for 2012.

The A1 e-tron has a range of more than 31 miles in city traffic, and its peak output of 102PS also makes it fun to drive. A compact internal combustion engine recharges the battery when its energy is depleted.

The powerful front-mounted, transverse electric motor thrusts the A1 e-tron forward with authority. The car sprints from a standstill to 62mph in only 10.2 seconds on its way to a top speed of more than 80mph. The compact MCV is a zero-emissions vehicle for the first 31.07 miles that it is underway, such as in city traffic. The battery comprises a package of lithium-ion modules mounted in the floor assembly in front of the rear axle.
A small, single-rotor Wankel engine is used in this near-series concept vehicle to increase the range in exceptional circumstances. This “range extender” powers a generator that produces 15 kW of charging power. If the range extender is used to recharge the battery, the A1 e-tron can cover an additional 124 miles of range. According to a draft standard for the computation of fuel consumption for range extender vehicles, this represents a fuel consumption of 148.7mpg – a CO2 equivalent of only 45 g/km.

The e-tron model family from Audi is just a few months old, but it already has a number of members, for each of which Audi has chosen a different drive technology. The first e-tron, which debuted at the 2009 IAA in Frankfurt, is a near-series high-performance sports car with electric motors for all four wheels. The study shown at the Detroit Motor Show in 2010 is a lightweight, compact two-seater with two electric motors on the rear axle.

The A1 e-tron now presents another approach – a compact electric car in the premium class. The four-passenger, two-door MCV city car was designed specifically for use in the metropolitan areas of Europe and North America and in the rapidly growing megacities of Asia and South America. The Audi A1 e-tron always drives on electric power; its internal combustion engine is only used to recharge the battery in isolated cases.

The synchronous electric motor of the Audi A1 e-tron is mounted transversely at the front of the car. Its low mounting position has a positive effect on the vehicle’s centre of gravity. Continuous output is rated at 61PS, with peak power of 102PS available in short bursts. 150 Nm (110.63 lb-ft) of torque is continuously available, and peak torque is 240 Nm (177.01 lb-ft).

The electric motor sends its power to the front wheels via a single-speed transmission. The elegant, retractable selector lever on the console of the centre tunnel used to choose between “Drive,” “Reverse,” and “Neutral” was taken from the first Audi e-tron.

The power electronics are mounted in the engine compartment above the electric motor. The most important components are the pulse-controlled inverter, which serves as the controller between the electric motor and the battery; the DC converter, which connects the high-voltage network with the 14 volt electrical system; a breaker unit to protect the high-voltage components; and the charging module. The socket for the standard charging plug is located behind the rings in the single-frame grille of the Audi A1 e-tron. A fully depleted battery can be recharged in approximately three hours from the 380 volt grid. A display immediately adjacent to the plug-in connection shows the current charge status and the charging time remaining.

The battery pack: a compact T arranged below the floor
The energy storage unit is arranged below the floor, where it is ideal for the centre of gravity and weight distribution. The battery pack is shaped like a T, with the short “transverse beam” filling the rear section of the centre tunnel and the “cross-beam” filling that area in front of the rear axle where the fuel tank is otherwise located. The 380 volt lithium-ion rechargeable battery has a nominal energy content of 12 kilowatt hours. It comprises 96 prismatic cells and weighs less than 150 kilograms (330.69 lb).

The Audi A1 e-tron can drive 31 miles emission-free in city traffic on the powerful battery. On longer trips, the battery is recharged by a particularly compact internal combustion engine mounted below the luggage compartment.

The range extender
The A1 e-tron concept car has a Wankel engine as a range extender, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window. The electronics also consider navigation data such as the destination and route profile to automatically activate the range extender as needed. The driver can also turn the range extender on and off as necessary with the push of a button. The fuel tank holds 12 liters.

The great strengths of the Wankel engine are the nearly vibration-free and quiet operation, the small dimensions, and the extremely low weight. Together with the generator, which is powered by the Wankel engine and produces 15 kW of electric power, the complete assembly weighs only around 70 kilograms. This weight also includes the special power electronics, the intake, exhaust, and cooling unit, plus the insulation and the subframe.

Driving experience
The first defining impression that the driver of the Audi A1 e-tron gets is that of nearly total silence. Even the Wankel engine in the back can barely be heard when it is running.

The second characteristic perception is the power of the electric motor, nearly all of which is available instantly and thrusts the Audi A1 e-tron forward with authority. The innovative Mega City Vehicle, which despite its complex drive technology weighs only 1,190 kilograms delivers zero-emission driving fun in a modern and sophisticated manner. The vehicle accelerates from 0 to 62mph in 10.2 seconds and has a top speed of more than 80mph.

The Audi A1 e-tron can also cover longer distances if the range extender charges the battery. The extra range, which is intended primarily for interurban driving, is 124 miles.

According to the draft standard, the two different operating modes yield a fuel economy figure of 148.7mpg, which corresponds to CO2 emissions of 45 g/km. In electric mode, there are zero local CO2 emissions – the compact A1 e-tron is thus ecological and economical.

The third impression that the A1 e-tron makes is that of a larger car. The compact two-door boasts all of the strengths of the new A1 model series – the carefully tuned, sporty chassis with specially designed 18 inch alloy wheels and 215/35 R18 tyres; the generous, “grown-up” interior; the excellent fit and finish; and a multitude of high-end equipment.

The dark shade “ebony” dominates the interior. The seats – with stone gray seams – and the headliner are in “Alabaster White.”

The Venga EV concept car is identical to the regular Venga B-segment MPV but features an electric motor producing 80 kW and maximum torque of 280 Nm.

Venga EV is capable of accelerating from standstill to 62mph in 11.8 seconds, and reaching a top speed of 87 mph.

Venga EV includes a twin-pack 24 kWh battery using innovative LiPoly (Lithium Ion Polymer) technology that offers numerous advantages over other battery types, and provides a driving range of 112 miles on a single charge.

Under the quick recharging cycle (50 kW) the battery can be recharged to 80 percent of its capacity within 20 minutes.  Under the normal cycle (3.3 kW), 100 percent power is attained after eight hours.

Venga EV is a front-wheel drive vehicle with the electric powertrain placed within the existing engine bay.  The battery pack is located under the boot floor.

As an all-electric, zero-emissions vehicle that is solely powered by electric energy stored inside its battery, Venga EV will contribute to increased environmental protection.

Venga EV represents Kia Motors’ continuing commitment to earth-positive R&D and marks an additional dimension in the company’s development of eco-friendly vehicles.

The SEAT IBE is 3.78 meters long – making it more than 25 centimeters shorter than an Ibiza – but its unusual breadth of 1.80 meters and overall height of just 122 centimeters lend it classic sports car proportions.

Classically sporty features of the two-door layout include its extremely low bonnet and long roof line.  The short front overhang and muscular rear end work together with the arch-filling 19-inch wheels to underscore the car’s powerful, compact look.

Visual highlights include the full LED headlamps, trademark Arrow Design nose, elongated and flattened V-shaped bonnet (made possible thanks to use of a full electric motor), broad ‘shoulders’ and sculpted flanks.  At the back, the rear light clusters again feature LED light guide technology and once again display the ‘arrow’ thematic.

Tightly cut as a 2+2, the IBE is conceived for youthful lifestyles and while it has plenty of space for a couple, there is also the possibility of carrying up to four.

The SEAT IBE’s motor is found beneath the extremely flat bonnet, with the lithium-ion battery positioned in the car’s very short rear.  With a maximum output of 75 kW (102 PS) and 200 Nm of torque, the power unit delivers exactly the kind of dynamic driving fun you might expect of a car that looks so sporty.  The typical ‘city dash’ from 0 to 50 km/h takes only 3.4 seconds; within 6.3 seconds the IBE has reached 80 km/h and, after only 9.4 seconds, it arrives at 100 km/h.

The 1,000 kg car’s continuous power rating is limited to 50 kW (68 PS), with the top speed pegged at 160 km/h – more than enough to cut an impressive dash even on urban motorways.

Battery capacity is 18 kWh, which is plenty to cover all the daily mobility requirements of city life.

It goes without saying, of course, that the SEAT IBE is equipped with the latest safety and communication systems and, in particular, is prepared for car-to-x communication. Anticipating the information network of the future, the car is even capable of exchanging data about its status or safety alerts directly with other vehicles or the traffic infrastructure.

At the end of 2012 Audi will launch the e-tron electric car that was seen last year at the Frankfurt Motor Show (IAA). A small series will be built, and will be the first electric car to reach the market.

Audi will be expanding its “e-tron” model family step by step: the A1 e-tron design study that the company is exhibiting at the Geneva Motor Show is an innovative Mega City Vehicle (MCV). Like the sports cars in the same family, it is electrically propelled and has a range of more than 50 kilometers (31 miles) in city traffic. With a peak power output of 75 kW (102 hp), the A1 e-tron is also fun to drive.

When the battery’s energy supply is exhausted, it is recharged by an exceptionally compact “range extender” consisting of a single-rotor Wankel engine and an electrical generator with a charge rating of up to 15 kW.

This device gives the A1 e-tron an additional range of 200 kilometers (124 miles). According to the draft standard for determining the fuel consumption of range-extender vehicles, the mean fuel consumption is 1.9 liters per 100 kilometers (123.8 US mpg), equivalent to CO2 emissions of only 45 g/km (72.42 g/mile).

The three-seat electric car has been designed primarily as an ecologically-acceptable vehicle for use in urban areas. It is 2.8 meters long, 1.7 meters wide and 1.6 meters high.

Powered by 32 KWh lithium – iron – phosphate batteries, DOK-ING XD promises to travel 250km (155 miles) on a single two-hour charge. It is equipped with a regenerative braking system enabling it to recharge during braking.

Two permanent 50 kW/65 HP new generation electromotors controlled by the DOK-ING manufactured electronics will be mounted onto the front wheels. 300 Nm torque guarantees exceptional acceleration while the maximum 130 km/h (80mph) as optimal speed and according to DOK-ING it can be adjusted according to customers’ requirements.

Safety features include 360 degree airbags, an integrated safety system for electric stability, and ABS brakes. Other features include power steering, and the ability to choose sport and economy drive modes to increase efficiency.

Mercedes-Benz’ F800 Style research vehicle is showing the future of premium automobiles from a new perspective, as the five-seat premium sedan combines highly efficient drive technologies with unparalleled safety and convenience features and an emotive design idiom, which interprets current Mercedes-Benz styling in line with the brand’s hallmark attribute of refined performance.

The F800 Style has a spacious interior full of intelligent seating, operating, and display concepts. Another unique feature of the large sedan is an all-new multi drive platform, which accommodates electric drives with fuel cells (enabling ranges of almost 375 miles) as well as the use of Plug-in Hybrids that can drive for up to 18 miles solely on electricity. Both variants of the F800 Style therefore make locally emission-free mobility possible at the level of a premium-class automobile, while at the same time being fully suited for everyday driving and providing a dynamic driving experience.

Both variants of the F800 Style therefore make locally emission-free mobility possible at the level of a premium-class automobile, while at the same time being fully suited for everyday driving and providing a dynamic driving experience.

F800 Style with Plug-in Hybrid
In combination with the very powerful Plug-in Hybrid drive system, the F800 Style is a very dynamic expression of the concept of “fascination and responsibility.” Its drive unit consists of a V6 gasoline engine with an output of 300 hp with next-generation direct injection and a hybrid module with an output 109 hp so that it delivers a total power of around 409 hp. The lithium-ion battery with a storage capacity of >10 kWh can be recharged either at a charging station or a household power socket.

Due to its efficient drive system and a CO2 bonus for the battery-electric driving mode, the vehicle has a certified fuel consumption of only 2.9 liters of gasoline per 100 kilometers. This corresponds to extremely low CO2 emissions of only 68 grams per kilometer. However, thanks to its outstanding efficiency, the F800 Style equipped with a Plug-in Hybrid nevertheless has a driving performance comparable to a sports car (0-60 mph 4.7 s, top speed of 155 mph). When in electric mode, the F800 Style has a top speed of 75 mph, thus meeting the needs associated with long-distance driving.

Like the Mercedes-Benz S400 HYBRID introduced in the summer of 2009 and the Vision S500 Plug-in Hybrid, the powerful electric module (approx. 80 kW) of the F800 Style is completely integrated into the housing of the seven-speed transmission. The lithium-ion battery in the new research vehicle is located underneath the rear seat, where it takes up little space, creates a low center of gravity, and ensures maximum safety in the event of a crash.

The electric drive components in the F800 Style with the Plug-in Hybrid once again demonstrate the versatility of Mercedes-Benz’ extensively scalable modular hybrid system. The hybrid system can be expanded in various ways, depending on performance needs and the area of application. On this basis, it is possible to combine hybrid modules and batteries of different performance ratings with fuel-efficient, high-torque gasoline and diesel engines. Examples range from the current mild hybrids all the way to Plug-in Hybrids that enable pure electric driving over long distances. In developing the F800 Style with Plug-in Hybrid, the Mercedes engineers specifically focused on improving the pure electric driving in urban traffic. Thanks to high power reserves, the F800 Style in e-mode easily masters all kinds of city traffic while producing no local emissions. With the new hybrid module, the top speed of the F800 Style with Plug-in Hybrid has been increased to 75 mph in electric mode compared to the Vision S500 Plug-in Hybrid. At the same time, it emits only 68 grams of CO2 per kilometer, compared to the latter vehicle’s 74 grams per kilometer.

The F800 Style with electric drive and fuel cell technology
The F800 Style also offers clean driving pleasure in the variant equipped with an electric drive based on fuel cell technology. The vehicle’s electric motor develops around 136 hp as well as a strong torque of approximately 214 lb-ft. The fuel cell generates the traction current by chemically reacting hydrogen with oxygen onboard the vehicle, producing water vapor in the process as the only emission.

The new Mercedes-Benz research vehicle has the fuel cell located in the front, while the compact electric motor is installed near the rear axle. The lithium-ion battery is located behind the rear seats and is protected as well as possible against the effects of accidents, as are the four hydrogen tanks. Two of the tanks are located in the transmission tunnel between the passengers, while the other two are underneath the rear seat.

F800 Style with further innovations for more comfort and safety
In addition to a multi-drive platform that is unparalleled for large sedans and the combination of different alternative drive technologies, the F800 Style features many other technological innovations, such as a new multi-function display concept and a human-machine interface (HMI) with a cam touchpad. The display shows many additional functions not typically found in conventional instrument clusters. The F800 Style’s display concept focuses for the first time primarily on electric driving functions.

The EYE concept car, produced in a full scale model version, was born out of the Institute’s desire to test the ability of its young designers and discover their vision of the future:  this led us to the choice of looking beyond traditional car manufacturers and join forces with a company which is synonymous with innovation Tesla is a company which produces 100% electric cars, whose green heart is perfectly in tune with its winning design, its sporting performance and the extremely pleasing driving experience its car offer.

EYE concept was born out of research into the identity promoted by Tesla to achieve a new objective:  designing an everyday  2 + 2 sports car conceived to become a status-symbol,  a car with engaging features and sports car performance ideally suited to a young, cosmopolitan target, particularly given its accessible price tag, and all those people who are constantly in touch with the world via the web and digital technologies.

EYE concept is the product of the work of eleven Master Course students, coordinated by Luca Borgogno, senior designer with Pininfarina and by Andrea Militello, Senior FIAT designer. The supervision of Franz von Holzhausen, Tesla Motors’ Chief Designer was fundamental to the entire process.

EYE was produced thanks to the collaboration of: Pirelli, OZ Racing.
