The 2019 Audi A5 40 TDI S Line Coupe is often described as the sweet spot of the luxury grand tourer world because it manages to look like a high-end exotic while remaining remarkably sensible to own. This model features what many enthusiasts consider to be one of the most beautiful silhouettes Audi has ever produced. The flowing wave shoulder line combined with the aggressive S Line body kit ensures the car looks modern and sharp without being overly loud or flashy. Under the hood, the 40 TDI engine is a powerhouse of efficiency and torque. Despite being a diesel, it provides a punchy 190hp that makes overtaking effortless on the motorway. One of its most impressive traits is its fuel economy, as it is common to see figures north of 50 mpg on long hauls. When paired with the S Tronic dual-clutch transmission, the gear shifts are nearly imperceptible, resulting in an elite cruising experience that feels both refined and composed. The interior is a masterclass in ergonomics and build quality. In 2019, Audi was still using physical climate control dials that provide a satisfying tactile click, a feature many drivers prefer over the all-touchscreen interfaces found in newer models. If the car is equipped with the Virtual Cockpit, you get a high-resolution digital dash that remains a gold standard for clarity and customization. Every surface feels premium, from the soft-touch plastics to the brushed aluminum inlays. While it is a sleek two-door coupe, it does not completely sacrifice practicality. The boot offers 465 liters of space, which is deep enough for a few large suitcases or a set of golf clubs. The cabin is also exceptionally quiet thanks to acoustic glazing that keeps road noise at bay even at higher speeds. It is worth noting that the S Line suspension is firmer than other trims, which provides sharper handling but means you will feel bumps more clearly on rougher roads. Ultimately, if you want a car that you will look back at every time you park it, but one that won't punish you at the fuel pump, this A5 is a stellar choice.
