The A4 looks sharp on the outside and has one of the highest quality interiors in the executive car class. The BMW 3 Series is a slightly better all-rounder and offers keen drivers greater thrills behind the wheel, but the A4 is more comfortable if you stick with our favourite Technik trim. The 35 TDI diesel that we also recommend in the A4 is quick, smooth and economical.
The 148bhp 35 TFSI needs to be worked fairly hard when building speed in a hurry but it'll tick off 0-62mph in 8.6sec and it's the most frugal petrol engine, averaging just over 46mpg (officially).
