This is a curious and intriguing car – and an expensive one when it carries the toys the test car came with. But more on that later. The intriguing part lies under the bonnet, where a 2.0-litre turbodiesel drives Audi’s excellent Direct Shift Gearbox (DSG), whose six speeds can be left to swap themselves if you don’t fancy doing it yourself with the transmission lever or the dinky little paddles tucked behind the steering wheel.
As recorded in the rave reviews the DSG transmission received on its debut appearance in the TT V6, this dual-clutch, sequential gearbox provides astonishingly jerk-free shifts, aided by engine management software that is almost never caught out. And that’s after repeated attempts to provoke a fluffed shift with sudden downchanges and jerky throttle inputs. Just occasionally traffic-jam progress can be a little uncushioned, but that has more to do with the diesel’s forceful engine braking than any transmission deficiencies.
The diesel itself is a VW group pumpe düse device, each cylinder getting its own injection pump. It yields over 40mpg and a fat 236lb ft of twist action between 1750 and 2500rpm and it’s this, rather than its 138bhp, that gives you a true clue to this engine’s ability to tug. Which is considerable.
Not that this is immediately apparent if you plant the transmission lever in D, where the combination of six gears and light throttle openings deliver somewhat lethargic performance – you need to be positive with the throttle to get ahead in the urban melee. This you can fix by pulling the lever into Sport, which has the transmission downshifting on a lighter throttle and hanging onto lower ratios longer. All of a sudden the A3 turns decidedly spritely, that relentless diesel thrust powering it ahead with satisfying authority.
