Gasoline Engine: The i8 also features a 1.5-liter turbocharged three-cylinder engine mounted at the rear. This engine produces 228 horsepower and 236 lb-ft of torque, driving the rear wheels. The combination of the electric motor and gasoline engine gives the i8 a total output of 369 horsepower.
Battery: The i8’s battery is a lithium-ion unit with a capacity of 11.6 kWh. It can be recharged via a standard electrical outlet or a dedicated charging station. The battery powers the electric motor and also provides energy for the car’s electric-only mode.
In summary, the BMW i8 is a plug-in hybrid that offers the flexibility of driving on electric power alone for short distances while also having the performance and range of a gasoline engine. This combination makes it a versatile vehicle, but it also means that the i8 is not fully electric.
Driving Modes: Balancing Electric and Gasoline Power
The BMW i8 offers several driving modes that allow the driver to choose how the car’s power sources are used:
eDrive Mode: In this mode, the i8 operates exclusively on electric power. It is ideal for short commutes or city driving where emissions-free travel is desired. The car is quiet and smooth, with a range limited by the battery’s charge.
Hybrid Mode: This mode optimizes the use of both the electric motor and the gasoline engine. The i8 automatically switches between the two power sources depending on driving conditions, balancing performance with efficiency.
Sport Mode: When maximum performance is required, Sport Mode engages both the electric motor and the gasoline engine to deliver the full 369 horsepower. The car’s suspension stiffens, and the throttle response becomes more aggressive, providing a true sports car experience.
These driving modes highlight the versatility of the BMW i8, allowing it to function as an eco-friendly electric vehicle when needed, while still offering the excitement of a traditional sports car.
Performance and Efficiency
Electric Range and Charging
As a plug-in hybrid, the BMW i8’s electric range is one of the critical aspects of its performance. On a full charge, the i8 can travel up to 18 miles purely on electric power. This range is sufficient for short trips or city driving but is relatively limited compared to fully electric vehicles (EVs) that can offer ranges of 200 miles or more.
Charging the i8’s battery can be done using a standard household outlet, which takes about 3-4 hours to reach a full charge. For faster charging, a Level 2 charger can reduce the time to about 1.5-2 hours. While the i8’s electric range may not be as extensive as that of a fully electric vehicle, its ability to recharge quickly and the presence of the gasoline engine ensures that range anxiety is not a significant concern for owners.
Hybrid Fuel Efficiency
The BMW i8’s hybrid powertrain is designed to offer a balance between performance and efficiency. In hybrid mode, the i8 delivers impressive fuel economy for a sports car, with an EPA-estimated rating of 69 MPGe (miles per gallon equivalent) when using both electric and gasoline power. When the battery is depleted, and the car relies solely on the gasoline engine, the fuel economy drops to around 27 MPG, which is still respectable for a vehicle in this class.
The combination of electric and gasoline power allows the i8 to cover long distances without frequent stops for refueling or recharging, making it a practical option for both daily commuting and longer road trips.
Performance Characteristics
Despite its hybrid nature, the BMW i8 doesn’t compromise on performance.
