宝马当地时间4月3日正式发布了2015款M4敞篷车,该车将在纽约车展正式与公众见面。这款车旨在吸引那些喜欢头发被微风吹起的富裕消费者，在M4敞篷车发布之前，宝马发布了M4轿跑车，两车同样采用了更具侵略性和肌肉感外观。与轿跑车相比，新车最大不同是采用了电动折叠硬顶，可在车辆时速18公里以下时在20秒内打开。车厢也采用了人们熟悉的内装设计，几乎可以说是完全照搬轿跑车。因此，内部配备了真皮运动方向盘和运动座椅，后者提供了足够的舒适性和支撑力度。车内其他亮点包括对比色缝线，M排挡杆和M侧踏板。该车与M4轿跑车一样搭载一台3.0升六缸TwinPower Turbo引擎，最大功率317千瓦/425马力，扭矩550牛米，如果搭配七速M DCT变速器，车辆0-60英里/小时（约合96公里）加速时间4.2秒，如果采用标配的六速手动变速器为4.4秒。无论选择何种变速器，该车经过电子限速后的最高时速为250公里。谈到配置，M4敞篷车还配备了M主动差速器，M复合刹车系统和M电子机械式转向系统。选装件包括M自适应悬挂（可提供舒适，运动和运动强化三种模式），采用土豪金涂装的M碳陶瓷刹车盘。M4敞篷车将于今夏在美国上市，售价将在临近上市时公布。
2015 BMW M4 Convertible unveiled, debuts in New York
BMW has officially unveiled the M4 Convertible ahead of its debut at the New York Auto Show.
Designed to appeal to well-heeled buyers who want to feel the breeze in their hair, the M4 Convertible follows in the footsteps of the M4 Coupe and adopts an aggressive exterior with muscular styling. The most noticeable difference is the power retractable hard top which can be lowered in 20 seconds at speeds up to 11 mph (18 km/h).
The familiar styling continues in the cabin as the model comes is virtually identical to the coupe. As a result, there's a leather-wrapped sport steering wheel and sport seats which promise to be comfortable and supportive. Other highlights include contrast stitching, an M gearshift and M-branded sill plates.
Like the M4 Coupe, the convertible is powered by a 3.0-liter TwinPower Turbo six-cylinder engine that develops 425 bhp (317 kW) and 406 lb-ft (550 Nm) of torque. This enables the car to accelerate from 0-60 mph in 4.2 seconds with the seven-speed M Double Clutch Transmission and 0-60 mph in 4.4 seconds with the standard six-speed manual. Regardless of which transmission is selected, the M4 Convertible has an electronically limited top speed of 155 mph (250 km).
Speaking of performance, the model has an Active M Differential, M compound brakes and an M-tuned electromechanical steering system. Options include an Adaptive M suspension (with COMFORT, SPORT and SPORT+ modes) and M carbon ceramic brakes with gold-painted calipers.
The M4 Convertible will go on sale in the United States this summer and pricing will be announced closer to launch.
