The RS5 takes the svelte lines of the A5 Coupé - one of the company's most successful designs of recent years - and injects it with somewhat more aggressive styling, all underpinned by a 450bhp V8 and paired with intelligent, adapatable quattro four-wheel drive.

想要和需要很少在世界上的汽车。虽然有许多例子说明了四个轮子、合适的引擎和光滑车身的飞溅可以使前者有效地胜过后者，但将两者拼接在一起的理由就更有说服力了。我们想要的汽车看起来很好，速度快，并使某种合乎逻辑的道理。奥迪的“RS”模型是一个完美的例子，如何实现这一点。自从1994年的第一辆RS，RS2，采取了一堆保时捷的机械设备，并把它们放在80前卫的曲线下面，这家位于Ingolstadt的制造商成功地提高了每一款后续车型的赌注。尽管推出了自己的真正的，独立的超级跑车，R8，“RS”的名称仍然作为一个‘光环产品’在每一个模型线的顶部。RS5采用了公司近年来最成功的设计之一A5政变的纤细线条，并注入了更具侵略性的造型，所有这些都以450 bhp V8为基础，并配以智能的、适配的四轮驱动。性能是充分的，足以把这个实用的四座在当代跑车的上层。然而，这些可以说是不必要的品质-高性能的反常“需求”-成功地与一辆四座汽车的日常“需求”相结合。因为尽管尖叫的V8，清晰的处理和刹车和令人兴奋的加速，RS5是真正实用的，一个功能机器的方式，许多竞争对手根本无法管理。我们经常被指责过分偏袒奥迪的方法汽车制造。但就像如今的每一家量产制造商一样，该公司从城市汽车到笨重的运动型多功能车(SUV)，通过两者之间的每一次排列，变得越来越薄。因此，并不是所有带有四个银环的东西都是杰作。但在RS5中-在很大程度上，它所基于的A5政变-奥迪(Audi)遭遇了一个甜蜜的时刻，它是一辆纯粹的司机的汽车，每天都可以随意使用，没有任何妥协。

Performance is more than ample, enough to put this practical four-seater in the upper echelon of contemporary sports cars.

And yet these arguably unnecessary qualities - the perverse 'wants' of high performance - are successfully blended with the everyday 'needs' of a four-seater car.

For despite the shrieking V8, the crisp handling and braking and the exhilarating acceleration, the RS5 is truly practical, a functional machine in a way that many rivals simply can't manage.

We're often accused of being overly partial to Audi's approach to car making. But like every volume manufacturer these days, the company is spread ever thinner from city cars to hulking SUVs, through every permutation in between. As a result, not everything that bears the four silver rings is a masterpiece. But in the RS5 - and to a large extent the A5 Coupé that it's based on - Audi has hit a sweet spot, a pure driver's car that can be used every day with discretion and zero compromise.
