At first glance, the BMW i8 comes across as a beautifully designed sports car. But it’s far more than that. Aerodynamics plays a key role in the design of the BMW i8, with each detail working toward channeling airflow for greater efficiency. Additionally, the streamflow design of the vehicle’s rear wing helps provide significant downforce all the way up to the electronically limited top speed of 155 mph.
From front to back, the BMW i8 is dedicated to reducing drag by employing EfficientDynamic ventilation technologies. These vents actively open and close to provide additional cooling, reduce the coefficient of drag, and improve the vehicle’s overall aerodynamics. Also, the front Air Curtains help channel airflow through the back vents to cool the TwinPower Turbo 3-cylinder engine in the rear of the car.
When a car looks this fast, it better live up to its appearance. The BMW i8 does just that, with help from its powerful, yet efficient TwinPower Turbo 3-cylinder combustion engine and its innovative electric motor. Together, these two engines work in tandem for uninterrupted acceleration from a standstill with a total system output of 420 lb-ft of torque and 357 horsepower.
As a plug-in hybrid with eDrive, the BMW i8 gets up to 76 MPGe fuel efficiency,4 far beyond conventional sports cars with comparable performance. And next to other plug-in hybrids, its dynamic sportiness is truly unmatched.
Every single aspect of the BMW i8 was selected to accomplish optimal performance. The choice to use lightweight materials in the construction helps make this plug-in hybrid vehicle as aerodynamic and sporty as possible. Its two-part structure uses both aluminum and Carbon Fiber Reinforced Plastic (CFRP) for their rigidity and extreme lightness in comparison to steel. As opposed to conventional glass, the acoustic separator between the engine and the cabin is made from substantially lighter chemically hardened glass.
