A selection of three TFSI petrol and five TDI diesel units will be available in various markets, with each engine Euro 6 emissions compliant and using up to 22 percent less fuel than in the previous model.
It’s the entry-level 2.0 litre diesel unit that offers the most frugal fuel usage at 4.2 l/100km (down from 5.0 l/100km) with a peak power output of 110kW.
A series of heavily-revised 3.0 litre V6 diesels are also available, with power outputs of 160kW or 200kW in single-turbo, and 235kW or 255kW (briefly) in the bi-turbo.
The petrol engines have also been redesigned, available in 1.8 litre form making 140kW and returning 5.7 l/100km or a 3.0 litre V6.
The top-spec diesel engine is matched with an eight-speed automatic transmission, while all other engines are available in various markets with either a six-speed manual or seven-speed S-tronic auto.
Audi announced it would phase-out Multitronic CVT autos from July, and the A6’s new range of transmissions reflects this decision.
Front styling has also been updated for 2015, including a redesigned grille, bumper, air inlets and new headlights.
Inside, the A6 gets new infotainment and assistance systems as standard, including an MMI navigation system on an eight-inch retractable monitor.
The Audi A6 allroad quattro will continue to form part of the range - available with the V6 petrol and diesel engines - while the S6 and RS 6 performance models get “numerous new features”.
The S6 variants add a 4.0 litre bi-turbo V8 petrol engine with ‘cylinder on demand’ making 331kW and with a 0-100km/h time of 4.4 seconds, along with quattro all-wheel-drive and an eight-speed automatic.
Choosing the S6 Avant adds 0.2 seconds to the 0-100km/h time, while fuel consumption is rated at 9.2 l/100km in the S6 and 9.4 l/100km in the S6 Avant.
Stepping up to the RS 6 Avant sees an even faster 0-100km/h time of 3.9 seconds (with a 305km/h top speed) and a power output of 412kW. Fuel consumption in the top-spec performer is 9.6 l/100km.
Delivery of the 2015 Audi A6 range for overseas markets will begin soon, with prices in Germany starting from €38,400 (AU$53,157).
Expect the updated Audi A6 range to arrive in local showrooms sometime next year with pricing and features yet to be confirmed.
We don’t expect any of the six-speed manual variants to be offered to Australian customers at this stage.
