what is the range on the bmw i3
BMW i3 BMW unveiled the i3 Concept Coupé study at the 2012 Los Angeles Auto Show. The carmaker developed the concept car to demonstrate the potential for extending the model range. The three-door hatchback coupe, like the five-door i3 electric hatchback sedan, is propelled by an electric motor developed by the BMW Group, with a maximum output of 125 kW/170 hp and peak torque of 250 N·m (184 lb-ft). Power delivery to the rear wheels is via a single-speed transmission. The li-ion battery pack is placed under the floor and can deliver an all-electric range of 160 km (99 mi), but a gasoline engine referred to as "REx", can be added to extend the car's range to 320 km (200 mi).[35][36]
Cell site The maximum range of a mast (where it is not limited by interference with other masts nearby) depends on the same considerations.In any case the limiting factor is the ability of a low-powered personal cell phone to transmit back to the mast. As a rough guide, based on a tall mast and flat terrain, it may be possible to get between 50 and 70 km (30–45 miles). When the terrain is hilly, the maximum distance can vary from as little as 5 kilometres (3.1 mi) to 8 kilometres (5.0 mi) due to encroachment of intermediate objects into the wide center fresnel zone of the signal.[6] Depending on terrain and other circumstances, a GSM Tower can replace between 2 and 50 miles (80 km) of cabling for fixed wireless networks.[7] In addition, some technologies, such as GSM, have an additional absolute maximum range of 35 kilometres (22 mi), which is imposed by technical limitations. CDMA and IDEN have no such limit defined by timing.
