The refresh is part of a £10.1m investment in new Audi products between 2011 and 2015; a programme that will add seven new models to its line-up, due to total 42 variants. It adds its new family “face” to the A5’s three body styles and brings emissions under 190g/km across the board.

Almost all of the engines have been modified to offer improvements in power and economy, with some impressively low figures for the entry-level units. The most frugal of these is a heavily modified version of the 175bhp 2.0 TDI, which now returns 60.1mpg and emits 122g/km in the front-wheel drive A5 Coupe.

There are similar improvements for the entry-level 1.8-litre TFSI, now producing 168bhp and capable of returning 49.6mpg and 134g/km; a 21% improvement compared to its 158bhp predecessor and only fractionally less than the outgoing 168bhp 2.0-litre TDI. This unit also replaces the 178bhp 2.0-litre TFSI.

Also new to the range is the 202bhp 3.0-litre V6 TDI. As fitted to the A6, A7 and A8, this replaces the 2.7-litre TDI unit, offering 57.6mpg and 129g/km in the front-wheel drive A5 Coupe. The 265bhp 3.2-litre FSI has also been dropped in favour of a 3.0-litre 270bhp unit, while the 330bhp V6 of the S5 Sportback and Cabriolet will now replace the V8 in the S5 Coupe, reducing CO2 emissions by up to 93g/km.

Inside, all models feature new colour schemes, trims and switchgear, with a redesigned steering wheel and the option of online services for the MMI in-car entertainment, featuring Google Maps and turning the A5 into a WiFi hotspot.

Prices for the new A5 range start at £25,540.
