BMW i8 Spyder Concept eDrive is a plug-in hybrid combines two different power sources and use the specific advantages of the electric motor and combustion engine for optimal effect. Key components of a hybrid drivetrain gel jointly a remarkable smoothness, which makes it possible to offer unrivaled dynamic capabilities and maximum efficiency. In other words, open-top two-seater sports performance machine-and-out yet posting a small car fuel economy.
Among the most interesting features of the BMW Concept i8 Spyder is up-spin, the door windows and a variety of purpose-oriented on-board electrical equipment, including kickboards kept under transparent tailgate. The sports car is based around an innovative LifeDrive architecture, itself underpinned by a lightweight modular construction and the use of high-quality high tech materials. BMW i8 Spyder Concept is a plug-in hybrid drivetrain powered by eDrive combines high performance electric motor and gasoline engine combustion. Lithium-ion batteries supply the motor with a rechargeable power in a very short space of any domestic power socket. Together, the car's weight is minimized, low center of gravity and finely judged balance, coupled with a combined system output to 260 kW (354 hp), the promise of dynamic capabilities are second to none, exceptional efficiency and unrestrained driving pleasure.
The electric motor energy source of lithium-ion battery that can be fully charged from domestic electricity socket in less than two hours. High-output battery is located in the tunnel of energy between the module front and rear axles to keep the cars center of gravity as low as possible - and therefore to maximize the dynamic performance of the car. Space-saving packaging and balanced these and other drives and chassis components to the distribution of two-seater sports an ideal 50:50 weight.
The 96 kW (131 hp) electric motor on the front axle to work jointly the three-cylinder turbocharged gasoline engine sends 164 kW (223 hp) through the rear wheels. Both in-house unit of BMW Group's development and produce an aggregate output of 260 kW system (354 hp) and peak torque of 550 Newton meters. That was enough to accelerate the Spyder Concept BMW i8 from 0 to 100 km h (62 mph) in five seconds on the way to electronically governed top speed of 250 km h (155 mph). Although this performance, two-seat burns only three liters of petrol per 100 kilometers (equivalent to fuel economy of 94 mpg imp) in the European test cycle.
With a fully charged battery, BMW i8 Spyder Concept can cover up to 30 kilometers (19 miles) on electrical power alone. Thus, far from filling up as a bit-part player, electric motors play a role similar to it of the gasoline engine. If necessary, a high voltage alternator is connected to the combustion engine produces extra energy, which is then stored in the hybrid battery. - Expanding variety of functions during the trip allows the two seats to travel further between filling stations.
