The Colibri's development stems from three general facts of current mobility behavior: the majority of people use individual means of transportation in their everyday lives, namely their own cars; statistically, each vehicle is occupied by less than two persons on average and travels daily distances of less than 55 kilometers / 34 miles. In face of this general framework, a cost-efficient one-seated vehicle with a range of well above 100 kilometers / 62 miles makes not only economic sense. Distinct features of the Colibri are the frame made of magnesium which is considerably lighter than comparable construction types and an electrically powered seat which is to increase the driver's comfort when entering or exiting the vehicle. Five other industrial companies and a university are involved in the development. R & D is subsidized by the German Federal Ministry of Education and Research. In 2012 the prototype was being built, while serial production was scheduled to start in 2014.
2013 World Premiere in Geneva
According to the manufacturer, it will be the first vehicle in its class (L7e) to successfully pass the Euro NCAP crash test – despite the low curb weight of 440 kg / 970 lbs including the battery. With the comparatively low-capacity battery holding 6.5 kWhrs of electric energy, ranges of up to 110 kilometers / 68 miles per charge can be achieved, as well as short recharging time of two hours on a 220 V household socket or less than twenty minutes to 80% capacity on a fast charging station. In addition, the Colibri will offer a fully enclosed cab and hence be weatherproof, unlike its already available competitor, the Renault Twizy. The trunk will offer 180 liters / 6.35 ft³ of cargo volume.
Due to its low weight, the vehicle is expected to achieve a maximum speed of up to 74 mph / 120 km/h and accelerate to 60 mph / 100 km/h in under 10 seconds. In contrast to comparable vehicles like the Renault Twizy, the Colibri will utilize a two-gear automatic transmission to reduce energy consumption at higher speeds.
The planned list price is set at 8,900 € for the base version, including VAT but excluding the monthly lease rate for the lithium iron phosphate battery of 55 €. Assuming an electricity price of 0.20 € per kWh, total costs per kilometer driven would be 0.17 €, including vehicle depreciation, battery lease, maintenance, taxes, insurance and energy. Compared to the most cost-efficient city car which, according to the German ADAC, costs around 0.30 €, a light elective vehicle like the Colibri saves 0.13 € / km. A compact car easily exceeds 0.40 € / km.
