smart is the first car brand with its sights set on a clean-cut switchover from combustion engines to electric drive: from 2020 the company plans to exclusively sell smart models with battery-electric drive in Europe and the USA. The rest of the world is expected to follow soon afterwards. Even today, smart electric drive models (combined power consumption: 13.1 - 12.9 kWh/100 km; combined CO2 emissions: 0 g/km) make opting into electric mobility more attractive than ever before. This is because they combine the agility of the smart with local emission-free driving. At the International Frankfurt Motor Show 2017 smart presented the smart vision EQ fortwo – an electric and autonomous vision for highly efficient and flexible local public transport. And with the new smart experienc-e app electric mobility can be experienced interactively.

The smart vision EQ fortwo offers a new solution for individualised, highly flexible and highly efficient local public transport. The autonomously driving electric one-off vehicle presents a consistent concept for urban mobility and car sharing of the future. It picks up its passengers directly from their chosen location and has no steering wheel or pedals. It is the first vehicle to embody all four pillars of the CASE strategy: "Connected", "Autonomous", "Shared" and "Electric".

"The smart vision EQ fortwo is our vision for urban mobility of the future; it is the most radical car sharing concept car ever to be developed: fully autonomous, highly communicative, friendly, extensively customisable and, of course, electric", says Annette Winkler, Head of smart.

New individualisation options help users to recognise that it is "their" vehicle: by means of the Black Panel grille at the front as well as large projection surfaces at the sides, the smart vision EQ fortwo allows unprecedented individualisation of the vehicle - ideal for car sharing. Freed from the task of driving, the passengers are able to relax in the large interior.

The smart vision EQ fortwo has a lithium-ion battery with a capacity of 30 kWh. When it is not in use the vehicle automatically heads for a charging station to recharge its battery. Alternatively, the cars can "dock" onto the power grid inductively, supply electricity and ease the load on the grid as a "swarm battery". Here smart is assuming an important function in the transition towards sustainable energy.

smart electric drive models: Electric cars for the city

smart electric drive makes opting into electric mobility more attractive than ever. This is because it combines the agility of the smart with local emission-free driving – the ideal match for urban mobility. Following the smart fortwo coupé and smart forfour (combined power consumption: 12.9/13.1 kWh/100 km; combined CO2 emissions: 0 g/km), the smart fortwo cabrio with battery-electric drive (combined power consumption: 13.0 kWh/100 km; combined CO2 emissions: 0 g/km) was launched in summer 2017.

With 160 Newton metres of torque immediately available, the 60 kW electric car boasts exceedingly agile acceleration. The fully charged battery offers a range that is ideal for urban use. With the high-performance on-board charger the smart electric drive can be charged at a household socket up to twice as fast as before – depending on the country version.

The electric motor takes the form of a separately excited three-phase synchronous motor. This configuration incorporates a winding on the rotor that is magnetised when current flows. The flow of energy from the high-voltage battery to the electric motor is controlled by the power electronics that are compactly interlocked with the drive unit.

Thanks to the power characteristics of the electric motor, the smart needs just one single fixed gear ratio. There is no need for any gear changing – a major advantage in dense city traffic. To reverse, the engine's direction of rotation changes.

The ECO mode is a particularly energy-efficient drive program. The radar-based recuperation controls energy recovery depending on the traffic situation. To save energy and extend the range, the smart electric drive also features pre-entry climate control.

With the "smart control" app a host of electric drive information can be called up via smartphone, tablet or PC and functions such as pre-entry climate control or intelligent charging can be conveniently controlled remotely.

For the new model year the Charge Spot Finder has been introduced as a new feature for the smart electric drive models (in conjunction with the Cool & Media package). This new function enables electricity charging stations nearby or in a certain city to be found with the navigation system.

smart experienc-e app: experience electric mobility interactively

The range of smart electric drive models can be experienced interactively and in a fun way with the new smart experienc-e app. 3D model, component scanner and range simulator are the three main functions of the free app for iOS and Android:

  • 3D model: three-dimensional views of the smart electric drive have touchpoints. If one of these points is selected on a smartphone or tablet PC, films, animations or explanations of the vehicle component or display in question open up.
  • Component scanner: with the camera of a smartphone components and displays can be scanned directly in the smart electric drive, for example at a motor show or at a dealership. Once the objects have been visually scanned an explanation of the corresponding function follows.
  • Range simulator: the individual range of the smart electric drive can be calculated here. The simulation considers whether the car is travelling at a low speed through the city or on country roads with a higher average speed. Further parameters such as tyre size, exterior temperature and activation/deactivation of air conditioning and pre-entry climate control are also included.

smart electric drive Carsino: participants stake their old cars

smart accompanied the market launch of the smart electric drive models with an international social media and digital campaign. In the summer of 2017 smart fans and interested car owners from Germany and Spain were able to apply to take part in "smart electric drive – Carsino". The participants had to wager their old car, which was subsequently pressed into a giant cube.

At the beginning of September the two finalists from Germany and Spain competed in the final with these "car dice" against two other participants from Belgium and the Netherlands in a big live event. The highest score was thrown by a Dutch participant. His prize was a new smart fortwo electric drive.
