宝马在今年的集团创新日发布了采用eDrive和Twin Power Turbo技术的2014款5系GT原型车。这款混动车的综合输出功率达到500千瓦/680马力，扭矩达到1015牛米。为电机供电的是一台20千瓦锂电池组，而两台电机分别以纵置方式安装在中央通道后面和横置方式安装在后座下面，后轴前部位置。完全充满电后，续航里程达到100公里，而普通内燃机可作为发电机提供电力，也可作为提升性能的助推器驱动前轮。在正常模式下，后置电机通过一台多速变速器驱动后轮。在混动模式下，车辆续航里程为595公里。而前置电机通过一台八速自动变速箱驱动车辆，在需要时可以形成全轮驱动方式。宝马并未公布该车重量，但考虑到增加了两台电机，电池组和混动系统，保守的估计车重将大大超过520d GT，大大1990公斤。
BMW shows off 5-Series GT with eDrive and TwinPower Turbo hybrid setup
BMW has introduced today during the Group Innovation Days 2014 a 5-Series GT prototype featuring eDrive and Twin Power Turbo technology.
BMW is providing a sneak preview of their future plug-in hybrid models which will eventually evolve to provide a massive combined output of more than 680 HP (500 kW) and a maximum torque exceeding 750 lb-ft (1,015 Nm). The electric motors part of the hybrid system get their energy from a 20 kWh lithium-ion battery which in the 5-Series GT has been installed both longitudinally at the back of the center tunnel and horizontally below the rear seat in an area in front of the rear axle.
A fully charged battery will be able to provide a maximum range of up to 62 miles (100 km) while the conventional engine can act as a generator to produce electricity or can work as a performance booster to power the front axle. In normal mode, the rear-mounted electric motor powers the rear wheels through a multi-speed gearbox. When used as a hybrid, the BMW 5-Series GT has an overall range of more than 370 miles (595 km).
There's also a front-mounted electric motor operated through the eight-speed automatic gearbox in which it has been incorporated granting the vehicle with an all-wheel drive system when necessary. The quoted 500 kW combined output is available when the two electric motors and the conventional engine work together.
BMW hasn't specified the weight of the car but taking into account they added two electric motors, a battery pack and the rest of the hybrid setup, it's safe to say it weighs significantly more than a regular 520d GT which tips the scales at 1,990 kg (4,387 lbs).
