    对于高档汽车厂商来说,既要确保产品具备一流的性能,还要引领当下环保潮流,看似是一对不可协调的矛盾。然而最近奥迪似乎寻找到了解决的办法:e-tron家族代表了奥迪对于未来汽车驱动方案的答案。
    最近推出的A3 e-tron是奥迪最新的尝试:A3 e-tron是一款独特的插电式混合动力汽车,在1.4TFSI发动机和一台集成在6挡双离合S-tronic变速器中的电动机共同驱动下,A3 e-tron的系统功率达到了150kW,扭矩350Nm,0~100km/h加速用时7.6s,保证了一流的用户体验。与此同时,这套插电式混合动力系统油耗最低仅为1.5L/100km。在纯电动模式下,A3 e-tron最高时速可达130km/h,最大续航里程50km。


    经过适当改动的1.4TFSI发动机功率110kW,75kW的盘状电动机集成在6挡S tronic双离合变速器中。这套系统具有相当高的灵活度:既可以由发动机单独驱动汽车,也可以由电动机驱动,或者两者共同驱动A3 e-tron的前轮,在滑行过程中,两者甚至可以同驱动轴全部断开,此时动能回收装置也停止工作,确保进一步提高燃油经济性。
在日内瓦车展上,奥迪将展出这辆具备划时代意义的e-tron,这也意味着奥迪e-tron品牌在未来将重点发展插电式混合动力技术。


The Audi A3 e-tron is a true Audi. It sprints from 0 to 100 km/h (62.14 mph) in 7.6 seconds on its way to a top speed of 222 km/h (137.94 mph). According to the ECE standard for plug-in hybrid automobiles, the five-door model consumes on average just 1.5 liters of fuel per 100 km (156.81 US mpg), which corresponds to CO2 emissions of 35 grams per km (56.33 g/mile). In electric mode, the Audi A3 e-tron reaches a top speed of 130 km/h (80.78 mph) and has a maximum range of 50 km (31.07 miles).3


The combustion engine is a modified 1.4 TFSI producing 110 kW (150 hp). A clutch links the TFSI to an electric motor with an output of 75 kW. The disc-shaped electric motor is integrated into a newly designed six-speed e-S tronic, which transfers the power to the front wheels. The two powerplants complement one another. The electric motor delivers its peak torque from start to around 2000 rpm, and the TFSI’s maximum pulling power is available in a range from 1,750 to 4,000 rpm.

The Audi A3 e-tron can be driven with just the combustion engine, just the electric drive or in hybrid mode. Even in electric mode it offers powerful acceleration without the need to engage the TFSI. The driver can choose to have both powerplants active at the same time (“boosting”). When the driver lets up on the accelerator, they both deactivate temporarily (“gliding”). In this way motor braking torque is eliminated and efficiency increases.

At the Geneva Motor Show, the Audi A3 e-tron will provide a realistic glimpse into the future of mobility as Audi is planning it. The electrification of the drivetrain, above all using plug-in technology, plays a deciding role in the strategy of the brand.
