Audi promises big car sophistication in a small package with their new A1 writes Geraldine Herbert What is it?  The A1 may be the smallest car in Audi’s range but it is every inch the premium car and proof that less really can be more. Who is it aimed at? With stylish looks and a very sophisticated interior Audi’s A1 will appeal to fashion conscious singletons. Styling? For 2015 the A1 has had a nip and tuck that includes new headlights and a redesigned bumper and grille unit but overall the changes go pretty much unnoticed. Under the Bonnet?

Available as a three or five door model the range starts at €21,450 and  three main trim levels are offered on the A1, entry-level, SE and S Line.  The SE  adds 16” alloy wheels; LED rear lights; sports seats; rear-parking sensors; contrast colour...
