The A1 S Line offers a premium feel in the sub-compact hatch segment, with high-quality cabin materials and a refined finish that punches above its size. Auto Express Engines—particularly the 1.4 TFSI petrol units—deliver a good blend of performance and efficiency, with real-world economy around the ,50–60 mpg mark depending on version. The sporty S Line trim adds visual flair and stronger equipment: sport suspension, alloy wheels, S Line styling and badges, helping it stand out and retain better value. bestcars.im Great for everyday use: compact size for town manoeuvring, decent boot space for the class, and a cabin that feels more sophisticated than many rivals.
