Great strides it is for the i-series models from BMW in the direction of maturity. A good year is in the mind of i8 Concept at the auto show in Beijing in late April 2012, the BMW Concept i8 Spyder.
Slightly shortened
Compared to the previous coupe variant, the i8 Spyder Concept to a slightly shorter wheelbase of 2.65 meters, was also the overall length of 15 centimeters to 4.48 meters reduced. In addition, the Spyder is a pure two-seater, the Concept is still i8 was designed as a 2 +2- seater. Striking features are no longer transparent swing doors. They already give it a clear indication of future production model. Under the transparent glass cover of the rear area, there are two e-kickboards, a type of skateboard with handlebars and engine. Inside, the materials and color scheme has been revised. The switches were previously futuristic and have now also been highly suggestive of the production version.
Life and continue
BMW has retained the so-called LifeDrive architecture, which consists of independent functional units. This is the “Life-module” from the very light carbon fiber passenger cell, while the majority take components made of aluminum “drive” all the modules driving-related functions, including powertrain, chassis and safety structure. A total of i8 Concept Spyder brings a curb weight of 1,630 kilograms. The Spyder will be on show in Beijing without a roof. An eventual production model of an open i8 gets a two-piece targa top, but has not yet adopted.
Double Heart
On the BMW Concept Spyder i8 plug-in hybrid technology is under the dynamic envelope. While on the front axle is a 96 kW respectively 131 HP electric motor operates strong, with the rear axle of a three-cylinder turbo petrol 164 kW or 223 hp is driven. The system power is 260 kW, which are 354 hp. Maximum torque of 550 Newton meters is available. So shall the i8 Spyder Concept sprint in five seconds from zero to 100 km / h to 250 km / h, electronically limited. Despite this, BMW sports car values on the average consumption of three liters per 100 kilometers.
Fast charging
The electric motor draws its energy from a lithium-ion battery that can be fully recharged at any household outlet in less than two hours. The battery sits in the so-called “energy keel” front and rear axle modules between to keep the center of gravity as low as possible. With full energy storage, the BMW Concept Spyder i8 cover up to 30 kilometers on electric power. It is stressed that the electric motor is not an auxiliary power unit, but an equivalent drive. If necessary, a a coupled to the internal combustion engine high-voltage generator also generates electricity that is stored in the hybrid battery. Alternatively, the front or rear wheels or all four wheels are driven simultaneously. An intelligent electronic control system ensures that every situation is selected in the optimal configuration.
Smart networked
Thus, the hybrid drive can operate at maximum efficiency, power electronics with intelligent navigation and traffic control systems is linked to. In this way information flow to the line profile, at any speed limits and inevitable traffic jams in the calculations of energy management to the operation of the hybrid strategy accordingly.
