Audi A7 (4G8)
The Audi A7 (4G8) is a sleek, coupe-like fastback based heavily on the A6 (C7) platform, blending executive saloon comfort with sweeping, distinctive styling. It occupies a niche between the A6 and A8, offering massive boot space under the hatch while commanding premium insurance rates and high running costs. It shares the same robust mechanicals as the A6, but also inherits the S tronic gearbox vulnerabilities and potential timing chain rattles on high-mileage V6 engines. It suits executives and long-distance drivers seeking a stylish, practical alternative to traditional saloons like the Mercedes CLS.
