The 2015 Audi A6 - now available only as a sedan following Audi Australia's decision to drop the slow-selling Avant wagon - gets revised headlights, a wider and flatter single-frame grille, and sharper body lines and cleaner surfaces front to rear for a more dynamic look overall.
Notable is Audi's new intelligent matrix LED headlight technology, which offers superior forward vision and auto dimming to prevent blinding oncoming drivers.
Inside there’s a new high-resolution driver information system that sits between the instrument cluster gauges and displays map information and more, meaning you don’t need to look down to the main, centre console-mounted screen when you’re navigating to a destination. The system is powered by a new, faster quad-core processor.
The 2015 launch line-up includes four engines: one petrol and two diesels for the A6, and a petrol for the S6. A smaller 2.0-litre diesel engine will join the A6 range later this year. Gone are the naturally aspirated 2.8-litre V6 and 3.0-litre supercharged V6 petrol engines.
A seven-speed S tronic dual-clutch transmission replaces the multitronic CVT in the entry-spec front-drive A6. The new 1.8-litre four-cylinder engine produces 140kW and 320Nm (up 8kW on the old 2.0-litre), uses 5.7 litres per 100 kilometres on the combined cycle (down from 6.4L/100km) and accelerates from 0-100km/h in 7.9 seconds (down from 8.3sec).
The 3.0-litre TDI produces 160kW and 500Nm, which is down a significant 20kW and 80Nm from the 2014 model. As a result, it's half a second slower from 0-100km/h (now 6.6 seconds) but 14 per cent more fuel efficient (now 5.1L/100km). It carries over its seven-speed S tronic gearbox.
Stepping up to the 3.0-litre TDI Biturbo V6 brings 235kW (up 5kW) and 650Nm and a ZF eight-speed tiptronic automatic transmission. This engine uses 6.1L/100km on the combined cycle (down from 6.4L/100km) and gets from 0-100km/h in 5.0 seconds (one tenth quicker than before).
The S6 sedan is powered by a 4.0-litre TFSI V8 engine that churns out 331kW and 550Nm (a 22kW gain over the old model). Accelerating from 0-100km/h takes 4.4 seconds (down 0.2secs) and fuel usage is 9.4L/100km (down 0.2L/100km). Four of the engine's eight cylinders can be deactivated under light throttle to aid efficiency.
Audi A6 1.8 TFSI equipment highlights include 18-inch alloy wheels, S line exterior package, xenon plus headlights with LED daytime running lights and high-beam assist, electric folding exterior mirrors, Audi side assist, parking system plus with front and rear cameras, convenience key, and the MMI Navigation plus infotainment system with MMI touch, Bluetooth interface, CD/DVD player, two SDHC card readers, new USB based Audi Music Interface (AMI), 10GB flash memory and DAB+ digital radio, playable through a 10-speaker audio system.
The A6 3.0 TDI gains Audi lane assist, four-zone climate control, LED headlights and rear dynamic indicators, while the top model in the A6 range, the 3.0 TDI Biturbo, adds 19-inch alloy wheels.
The optional Technik Package costs $4800 and includes adaptive cruise control with stop and go, Audi Pre-sense plus, park assist, 360-degree camera and Audi Connect internet functionality. Active lane assist and four-zone climate control can be added to the 1.8 TFSI model, which takes the price of the package to $5800.
