The engine model of the BMW i8 is B38K15A, which consists of a 1.5T twin-turbocharged engine and an electric motor. This engine has a maximum power of 231 horsepower and a maximum torque of 320 Nm, while the electric motor delivers a maximum power of 96 kW and a maximum torque output of 250 Nm. The BMW i8 is a hybrid two-door supercar with body dimensions of 4689mm in length, 1942mm in width, and 1299mm in height, and a wheelbase of 2800mm. In terms of exterior design, the rear wheel arches of the BMW i8 are positioned close to the doors, and the fuel tank cap is located on the wheel arches.
The engine model of the BMW i8 is the B38B15A. This is a 1.5-liter three-cylinder turbocharged engine, paired with a rear-mounted electric motor to form a hybrid system. During my research on cars, I discovered that despite its small displacement, this engine delivers an impressive 231 horsepower thanks to turbocharging, enabling rapid acceleration from 0 to 100 km/h in just 4.4 seconds. Its application in the i8 is quite unique—the gasoline engine primarily drives the rear wheels, while the front wheels are propelled by the electric motor, creating an all-wheel-drive feel. In daily driving, it remains quiet and smooth, with a deep, refined engine growl at high speeds. Fuel efficiency is also excellent, averaging around 2.1 liters per 100 kilometers, aided by regenerative braking for energy recovery. The overall design emphasizes lightweight construction, using aluminum materials to reduce weight. Maintenance requires regular checks on the air filter and fluids, making it ideal for drivers who seek performance without sacrificing fuel economy.
I've been driving my BMW i8 for over a year now, and that 1.5-liter three-cylinder turbocharged engine, model B38B15A, paired with an electric motor feels absolutely exhilarating. At startup, the electric motor silently propels the car forward, and with a press of the accelerator, the engine instantly delivers a burst of power. The combined output of 231 horsepower makes overtaking incredibly easy. For city commuting, the pure electric mode can cover about 37 kilometers, and a full tank of gas allows for over 600 kilometers of driving, saving quite a bit on fuel costs. On the highway, the engine sound is deep and powerful, but the cabin noise control is excellent, avoiding the loudness typical of some high-displacement cars. During maintenance, I noticed the oil change intervals are relatively long, approximately every 15,000 kilometers, and the cost isn't too high. Overall, the driving position is low, and the steering is precise, making it ideal for young people who enjoy a sporty feel. I've taken it for spins on mountain roads—the chassis tuning is firm yet still comfortable. Occasionally, the battery performance dips slightly in extremely cold weather, but it's not a significant issue.
