Smart electric drive

The Smart EQ Fortwo, formerly Smart Fortwo electric drive, smart ed or Smart Fortwo EV, is a battery electric vehicle variant of the Smart Fortwo city car made by Smart. Since 2020, Smart is only selling battery EVs.

The Smart EQ Forfour was an electric variant of the long wheelbase four-door second generation Smart Forfour city car Type 453 which shared approximately 70% of its parts with the third-generation Renault Twingo, both built by Renault in Slovenia.

Field testing of the electric Smart Fortwo 450 began in London with 100 units in 2007, leasing only due to the cumbersome molten salt ZEBRA battery. With drive train and lithium-ion battery provided by a California startup named Tesla, the second-generation ED with the second-generation 451 chassis was introduced in 2009 and made available in 18 markets around the world for leasing, or through the Car2Go carsharing service in selected cities, with over 2,300 units delivered.

A near production version of the third-generation Smart ED, using the face lift 451 body and drive train plus complete LiIon battery built by Daimler joint ventures, was unveiled at the September 2011 Frankfurt Motor Show. Smart started in 2012 to mass-produce the electric car for regular availability in up to 30 markets worldwide. Deliveries of the third-generation Smart ED began in the U.S. and Europe in May 2013. More than 8,800 units of the second and third generation Smart ED were sold in North America and Europe between 2009 and June 2014,  of which, over 6,500 units are third generation variants.

Since 2017, the fourth-generation Smart Electric Drive is being sold. As Daimler discontinued the electric joint ventures, it uses a Renault drive train, the fourth variant in as many electric generations. The body corresponds to the third-generation ICE-powered Smart 453; this mismatch in the numbering of generations arose because the Smart ED2 and the Smart ED3 were both based on the second-generation ICE-powered Smart 451.

First generation
The first Smart electric drive vehicles, still using the first generation type 450 body style, were modified by Zytek Electric Vehicles. They were powered by a rear-mounted motor driving the rear wheels. It ran on 13.2 kilowatt hours of sodium-nickel chloride Zebra batteries. These type of molten salt battery operates at 245 °C (473 °F). It is typically kept molten and ready for use because if allowed to "freeze" it takes twelve hours to reheat and charge. Thus it is not very useful for private owners, but rather in fleets of taxis, police cars and other vehicles that are operated by multiple users.

Field testing began in London with 100 vehicles in 2007 and was available only for lease to corporate clients for £375 per month.

Second generation
The second generation, Smart ED2, was introduced in 2009 to 18 markets with the objective to gather experience about how customers use and charge electric vehicles. Daimler initially planned to build 1,000 vehicles, but as demand exceeded the company's expectations, more than 2,000 Smart Fortwo electric drive cars were produced. The electric cars were available for leasing or through the Car2Go carsharing service in San Diego, Amsterdam and Vancouver. Production of the second-generation Smart Fortwo electric drive began in November 2009 in Smartville, Hambach, France. The Smart ED2s have a 16.5 kWh lithium-ion battery provided by Tesla, Inc. and a powertrain provided by Zytek. The range of a fully charged battery is up to 135 km under the New European Driving Cycle (NEDC) cycle. As part of a three-phase roll-out program, phase two began with field testing in Berlin in December 2009 with 100 units out of 300 that will be deployed in Germany. For phase two 1,500 cars were produced, and field tested in Hamburg, Paris, Rome, Milan, Pisa, London, the English Midlands, Madrid, Zurich, Portugal, Denmark, the Czech Republic, Austria, Belgium and the Netherlands during the first half of 2010. In October 2010, 250 units were made available for field testing in several cities in the United States. Testing also was conducted in Canada; and in 2011 in selected markets in Asia.

Phase three of the program is mass production, which was scheduled to begin with the 2012 model year. In the United States sales were scheduled to begin in 2012 with the 2013 model year. In July 2011 an agreement was reached between Daimler AG and Robert Bosch GmbH to develop and produce innovative traction motors for electric vehicles. Based on this joint venture, Daimler planned to use the improved traction motors with the third generation of Smart electric drive cars scheduled to go on sale in 2012.

Specifications
The lithium-ion battery pack took three hours to charge from 20 to 80 percent of its capacity with a standard 230 V outlet. It could also be charged using a common US household 120 V outlet. The car has a 3.3 kW on-board charger for this AC charging. Smart claims a 0 - 60 km/h time of 6.5 seconds, the same as for the gasoline version. It has a single fixed-gear ratio transmission and is about 308 lb heavier than a gasoline-powered Fortwo.

Markets and sales
Over 2,300 units of the second generation models were leased between 2009 and October 2012 in 18 markets around the world. Of these, 1,721 units were registered in Europe through October 2012, and 527 units in the U.S. through December 2012.

United States
The trial program in the US began in January 2011 with the first customer delivery in Washington, D.C. A total of 250 units were made available for leasing at a price of US$599 per month for a period of 48 months and 60000 km, plus $2,500 due at signing. This pricing is before taxes or any government tax credits or rebates available. The limited fleet of second-generation Smart Fortwo electric drive cars was introduced first in Portland, Oregon, Los Angeles, San Jose, California, Orlando, Florida, Austin, Detroit, Indianapolis and the Interstate 95 corridor between Washington, D.C., and Boston, including New Jersey and New York. In July 2011, Car2Go announced the deployment of a fleet of Smart EDs into carsharing service in San Diego before the end of 2011. The company stated that the carsharing electric cars will have a range of 84 mi, and, based on their experience with usage in other cities, they will most likely need to be recharged every two or three days. When reserving the electric car online, San Diego Car2Go members are able to see the battery's state of charge, so if the customer wants to go for an extended drive, the option is available to find the right car for that trip.

In November 2011 fleets of 300 Smart EDs each were deployed in San Diego and Amsterdam as part of the Car2Go service. , a total of 527 Smart EDs were registered in the US since January 2011, including 300 units deployed for Car2Go in San Diego.

Considering an energy consumption of 39 kilowatt-hours per 100 miles (22 MJ/km) and a conversion factor of 33.7 kWh of electricity being the energy equivalent of a US gallon of gasoline ( megajoules to the litre), the US Environmental Protection Agency officially rated the Smart ED combined fuel economy at 87 miles per gallon gasoline equivalent (mpg-e) (2.7 L gasoline equivalent/100 km; 104 mpg-imp gasoline equivalent), 94 mpgus city and 79 mpgus highway. EPA's official all-electric range is 63 mi, but in favorable conditions in an urban environment at warm temperatures the carmaker claims the Smart Fortwo ED can reach up to 98 mi. According to Forbes, the American Council for an Energy Efficient Economy ranked the Smart ForTwo Electric Drive the "greenest" car for 2014.

France
A total of 152 Smart EDs were registered in France since 2010 through December 2012.

Third generation
The third-generation Smart electric drive, Smart ED3, was unveiled at the September 2011 Frankfurt Motor Show. Key differences with the second-generation model include a more powerful electric motor with improved acceleration and top speed; a new lithium-ion battery pack, which increased the range to 140 km with a quick-charge option; other new features include an enlarged grille opening, LED daytime running lights, wider door sills, some minor modifications to the rear, fully automatic air conditioning with pollen filter and pre-air conditioning. Several features are controlled remotely through a smart drive application for the iPhone. In Germany the Smart ED was available for €16,000 (around US$22,400) plus a monthly fee of €60 (US$84) for the battery rental. Online reservations were scheduled to begin in the fourth quarter 2011. In the US pricing started at US$25,750 and US$28,750 for the Soft Top Cabriolet before any applicable government incentives. Canadian pricing for the Electric Drive starts at CA$26,990 and the cabriolet version started at CA$29,990.

The third-generation Smart electric drive was released in the US in May 2013 with 60 units delivered that month. Sales in Europe also began in May 2013. Smart planned to mass-produce the electric car with availability in 30 markets worldwide.

In February 2014, Smart announced it would be offering the 2014 model year nationwide; the 2013 model was only available in CARB states.

Also available as a cabriolet, it is the only current production electric convertible in the world.

The model was later renamed as Smart EQ Fortwo in 2018 as Daimler started to use EQ brand for electric car lineup.

A facelifted model was unveiled in 2019, for the 2020 model year.

Smart EQ Forfour


Starting from this generation, the electric Smart is also available as a 5-door hatchback. The Smart EQ Forfour is a battery electric variant of the Smart Forfour, powered by a 60 kW motor. Just like its ICE counterpart, it shares its platform with the Renault Twingo and is manufactured in Novo Mesto, Slovenia. The battery capacity is 17.6 kWh, out of which 16.7 kWh is usable. Its electricity consumption is 13.1 kWh/100 km, therefore equating to a range of 127.48 km.

Essential importance for Tesla Motors
Although Tesla Motors was not directly involved in the development of the final Smart ED3 purchase model, the Daimler partnership concerning the Smart ED2 was essential for Tesla. Elon Musk said at the 2016 Tesla shareholder meeting: "If we hadn’t done that [the Daimler cooperation], Tesla would have died because the Daimler partnership gave us credibility, that a major OEM was willing to work with us, and they also paid us for the [Smart ED2] development program which is really helpful from a revenue standpoint". "Without that investment, Tesla would have been game over".
