BMW I

BMW eDRIVE.

BMW eDRIVE.

The BMW eDrive technology is the result of many years of BMW EfficientDynamics development work. The full torque of the agile electric motor is available from a standing start and makes for unrivalled driving pleasure. At the same time, an innovative cooling system keeps the high-voltage batteries at their optimum operating temperature, which increases performance and service life.

Intelligent energy management coordinates the interaction between the electric motor with battery and the electric motor with combustion engine, and is always geared towards maximum performance with minimum consumption. The result is a powerful and efficient plug-in hybrid system.

  • Powerful plug-in hybrid system

    Think further to go further. The intelligent eDrive propulsion system of the BMW i8 combines the benefits of an electric motor and a gasoline engine as a plug-in hybrid to create an exceptional driving experience: Outstanding efficiency and maximum dynamics are simultaneously possible. The electric drive, a powerful 131 hp motor, is located on the front axle. In contrast, the rear axle is driven by a powerful BMW TwinPower Turbo 1.5-litre 3-cylinder gasoline engine with 231 hp of peak performance and up to 236 lb-ft of torque; combined with the electrical boost of the hybrid system, it guarantees typical BMW driving pleasure. These two drive systems combine to accelerate the BMW i8 from 0 to 100 km/h in 4.4 seconds – with fuel consumption of just 2.1 l per 100 km.

  • Intelligent energy management

    The astonishing efficiency of the BMW i8 is a result of the perfect interplay between BMW eDrive technology and gasoline engine. How the two system components are utilized is precisely coordinated according to the driving mode and situation in order to meet the specific requirements. At the same time, brake energy regenerated through one-pedal driving and during the deceleration processes ensures an efficient increase in the purely electrical range. The aerodynamically optimized design additionally contributes to the ability of the BMW i8, as a thoroughbred sports car, to achieve consumption and emission figures comparable with those of a compact car.

BMW TWINPOWER TURBO 1.5 LITRE 3-CYLINDER GASOLINE ENGINE.

BMW TWINPOWER TURBO 1.5 LITRE 3-CYLINDER GASOLINE ENGINE.

The BMW TwinPower Turbo 1.5-litre 3-cylinder gasoline engine, which was newly developed as part of the BMW EfficientDynamics strategy, unites all the advantages that one would expect from the power unit of a sports car. Its engine management guarantees optimum charge changing processes across the ignition point and ensures a rapid response from the turbocharger. During operation, the 231 hp engine proves to be extremely free-revving and delivers up to 236 lb-ft of torque. At the same time, the dynamics and the high performance level are accompanied by outstanding efficiency, as demonstrated by the combined consumption of only 8.3 l/100 km.
 

DRIVING MODES.

A variety of modes for an exceptional driving experience: COMFORT, ECO PRO, SPORT and the eDrive button optimize the vehicle properties of your BMW i8 to suit the driving situation. 100% electric driving is possible up to a range of 37 km* as is an extremely athletic sports car for out-of-town driving. Between the two lies the best of both worlds: the gasoline engine and electric motor constantly demonstrate that their technical symbiosis is never a compromise.

Pressing the eDrive button adapts the BMW i8 for purely electric driving. This is possible in the COMFORT and ECO PRO modes. In the COMFORT mode with eDrive, the BMW i8 drives without support from the combustion engine until the battery is almost exhausted. Purely electrical driving at speeds of up to 120 km/h is possible with eDrive. If the button isn’t pressed the combustion engine is activated at 60 km/h.

* Determined in internal BMW consumption studies. The driving range is depending on a variety of factors, especially: personal driving behaviour, selected route, weather conditions, usage of heating/cooling and preconditioning.

  • COMFORT mode

    All the power you need as soon as you drive off. In the COMFORT mode, the fully-charged BMW i8 starts electrically. Purely electrical driving is possible up to approximately 120 km/h, and also covers pulling away from traffic lights and overtaking. At higher speeds, the combustion engine is activated as well and guarantees optimum driving comfort.

  • ECO PRO mode

    The ECO PRO mode allows the BMW i8 to demonstrate its efficiency. The accelerator and transmission as well as the heating and cooling systems are all adjusted to be as efficient as possible. Purely electrical driving is possible up to a speed of 120 km/h. In addition to this, the combustion engine is activated at high speeds or when the battery charge level falls below a specified minimum.

  • SPORT mode

    As an alternative to the transmission setting ‘D’ for automatic driving, the driver can also use the gear lever to change to the SPORT mode. This mode also includes manual gear selection – via the gearshift or paddles on the steering wheel. The SPORT mode also activates vehicle settings that are especially suited to sporty driving. The combustion engine and the electric motor unleash their driving torque with maximum dynamics, the accelerator’s characteristic line is programmed to react spontaneously, and the driver enjoys the full impact of the electric motor’s boost function. To ensure there is always enough energy available, the SPORT setting also affords maximum energy regeneration in the thrust and brake phases.

ALL-WHEEL DRIVE.

With the eDrive button pressed, 100 % electric driving is possible in the BMW i8, with power coming via the front axle only. The hybrid mode allows the intelligent combination of two types of drive that provide optimal traction in every situation. The electric drive is located on the front axle, while a high-performance 3-cylinder engine works at the rear axle.

All four wheels can thus be powered simultaneously by two engines, and – depending on the driving situation – this utilises the advantages of front-wheel drive or all-wheel drive. Outside the city, the fully-fledged all-wheel drive of the BMW i8 shows its true strength – at speeds of up to 250 km/h.
