讴歌近日表示，2019款讴歌RDX是讴歌最近10年来改款幅度最大的车型，新车将有多项升级，这主要归功于新的平台。讴歌老板乔恩·池田(JonIkeda)近日在接受美国媒体采访时证实，新一代RDX将不再与本田CR-V有任何联系。新平台可以更有效的利用空间，内装也更优异，改变的结果是轴距略微增加，乘客和储物空间更宽敞。如果将后排椅背放平，可以形成一个完全平整的行李箱。由于新平台高强度钢材使用量超过整体结构一半以上，因此可以让车身刚性获得提升。改进后的悬挂采用新的五连杆后悬，同时提供可变齿比电子助力转向并可选装自适应减震。最后，新车还将提供讴歌的扭矩矢量控制SH-AWD系统，而老款车并未提供这项配置。该系统可将最多70%动力传递至后轮，同时可将所有动力分配给左右两侧车辆，因此可提升操控性和牵引力控制。

 

2019 Acura RDX Rides On New Platform; Not Related To Honda CR-V

The 2019 RDX is the most extensive (and probably the most expensive) redesign for the model in the last decade, Acura says, and brings a number of very important improvements. That’s possible thanks to a new platform, which is actually something new for the company.

 

In a recent interview to MotorTrend, Acura boss Jon Ikeda re-confirmed the architecture in question is not related to the Honda CR-V, something we heard for the first time in Detroit earlier this year, when the brand revealed the RDX prototype. The new platform allows for more efficient use of space and better packaging, which translates to a slightly longer wheelbase and more room for passengers and luggage in the cabin. For example, when the rear seats are folded, the floor is fully flat.

 

The new architecture also brings advantages in terms of rigidity because of the high-strength steel used in over half of its construction. The underpinnings are now home of a revised suspension with a new five-link independent rear layout, variable-ratio electric power steering, and optionally available adaptive dampers.

 

Last but not least, the new RDX also gains Acura’s torque vectoring SH-AWD system, which was absent in the model it replaces. It can distribute up to 70 percent of the power to the rear axle and all of it can be delivered to either side for the benefit of handling and improved traction.
