BMW, the German carmaker of premium vehicles has just unveiled the i8 Spyder Concept Auto China in Beijing. In future, the designation eDrive will identify the drive technology for all electric and plug-in hybrid cars from BMW i.
eDrive-powered BMWs share a couple of components, including the electric motor developed in-house by BMW, the lithium-ion battery, and finally the intelligent motor management system.
The hybrids, like the i8, will also get a gasoline or diesel engine to back the electric motors, while the EVs, like the i3, only rely on the motors.
The low seating position of BMW i8 Spyder gives you exciting driving experience, said one of the officials during the expo.
It is a mid-engine sports car. With its electric driven front axle and its petrol driven rear axle it has 4 by 4 capabilities. From a technical standpoint, it is closely related to the coupé version. The Spyder has the same vehicle architecture with two separate modules:
• The Drive Module, made mostly of aluminium, with the powertrain, chassis and safety structure; and
• The Life module, built of carbon-fibre. This forms an extremely lightweight passenger cell.
The plug-in hybrid drive train of the BMW i8 Concept Spyder has the same configuration as the coupé:
• an electric motor powers the front axle, and
• a turbocharged three-cylinder petrol engine powers the rear axle.
This system delivers a combined output of up to 354 horsepower – which is a little more than a BMW 1 series M Coupé displaces. The i8 Spyder delivers a maximum torque of 550 Newton meters. This is 30 Newton meters more than the last generation M6.
