Buddy is a Norway electric city car, produced by Buddy Electric in the early 2000s, formerly known as Pure Mobility and Elbil Norge AS, at Økern in Oslo. In 2007, the Buddy, and its predecessor, the Kewet, made up 20% of the electric cars in Norway .[1][failed verification] Since its inception in 1991, combined sales of the Kewet and Buddy had totaled about 1,500 vehicles through October 2013,[2] of which, 1,087 were registered in Norway.[3]

History

Buddy is the sixth generation of the Kewet electric vehicle. Originally, the Kewet was developed in Hadsund, Denmark , and the first model was made in 1991. Production alternated between Hadsund, Denmark and Nordhausen, Germany . During the first five generations, over 1000 electric vehicles were produced. They were sold in 18 countries. In 1998, all rights were acquired by ElBil Norge AS (which, at the time, was called Kollega Bil AS). For some years, ElBil Norge further developed the vehicle and in the autumn of 2005, a new model was presented that was first called Kewet Buddy Citi-Jet 6, but is now known simply as the Buddy.[citation needed]

In December 2008, the first 12 Buddy cars were sent from the Buddy factory in Økern by boat to Copenhagen.[4] In 2010, Pure Mobility (former "Elbil Norge") launched a new version of the Buddy, initially marketed as "MetroBuddy", but the "Metro" prefix was removed due to negative or confusing associations with the term.

Technology and production

Buddy is a simple, functional, electric city car with a range of 20 to 60 km (12 to 37 mi) depending on the season, topography and driving style. Its maximum speed is 80 km/h (50 mph). Its length is 244 cm (96 in), which allows it in some jurisdictions to be legally parked sideways.[citation needed]

The Buddy consists of a strong, hot galvanized steel tube frame with safety cage, but with no proper deformation zones. The body is made of thin fiberglass. Other metal parts are treated so that further rust treatment is unnecessary. The electric motor is a 72V Sepex 13 kW, a direct current motor with brushes. Well-tried technological solutions have been used for maximal reliability. The car has no servo or aids regarding steering and braking, and the response and "connection" to brakes and front wheels are vague and difficult to finesse. It also lacks safety equipment such as ABS, ESP or airbags.[citation needed]

The Buddy was produced with lead acid batteries which, when completely discharged, can be recharged in 6–8 hours, or rapidly charged so that one hour's charging allows the vehicle to be driven about 10 km (6.2 mi). Charging uses an ordinary grounded outlet with a minimum circuit of 10 A. The batteries' life expectancy is 2–5 years, or about 20 000 km, depending on driving and charging habits. A complete battery set costs from GB£2,800, excluding value added tax.[citation needed]

ElBil Norge has made a development fleet of Buddy vehicles equipped with various forms of Li-ion battery technology. When the technology becomes available commercially, existing vehicles will potentially be upgradeable.[citation needed]

The Buddy was EU approved[when?] as a heavy quadricycle (an electric four-wheel motorcycle) by the Vehicle Certification Agency. It can be used as an ordinary vehicle without restrictions, and drivers require only an ordinary driver's license.

Two models of the Buddy were available: the standard version, and the BuddyCab with a folding roof. In 2007, production at Økern in Oslo was 5–6 vehicles a week, with a theoretical capacity of 500 vehicles annually. To meet international needs, ElBil Norge was working[when?] to establish new production facilities. The Buddy has been sold only in Norway while the company prepares for export.[citation needed]

As of late 2008, plans were under way for an additional factory in Portugal, with projected production of 5000 cars per year.[5][needs update]

Sales

Parking the Buddy in perpendicular position to the sidewalk is legal in Norway at spaces reserved for motorcycles.

The Buddy ranked 29th in sales by automotive brands in Norway in 2006, ahead of Jaguar, Fiat, Smart and Porsche.[6] While most other cars there are dark or muted colors, about 80% of Buddys are delivered in a multitude of strong, bright colours,[7] with many using bold decorative elements such as flowers, hearts, clouds, and flames. One cloud-covered Buddy was designed to match the owner's night table lamp.[8]

125 Buddies were sold in Norway in 2011, a market share of 6% of all electric vehicles sold in the country that year.[9] (As of September 2013), 1,087 units were registered in Norway, the leading market, consisting of 2 Kewet CITI VANs, 22 Kewet EL-JET (1–4)s, 50 Kewet CITI JET 5s, 379 Buddy M9 (2010–2013), and 634 Kewet Buddy Citi-Jet 6 (2005–2009).[3]

Operations and ownership

Buddy was produced by Buddy Electric (formerly known as "Pure Mobility" and "ElBil Norge AS") which in 2003 changed its name from Kollega Bil AS. Originally established in 1992, it has been in the electric vehicle business since that time. Its managing director is Kjell Strøm. Elbil Norge AS is owned by its original founders Jan-Petter Skram and Viggo Vargum, and external investors include Hafslund Venture AS, Gezina AS (Th. Brøvig), members of the Selvaag family, Lychegaarden (Jens P. Heyerdahl) and Jan Chr G Sundt. The owners have gradually expanded the company. In 2005, the owners invested NOK 12 million to expand the Økern factory. ElBil Norge was profitable in 2004 and 2005 and has a ratio of owner equity to debt of 90%.[citation needed]
