The Audi A8 has received new engines and extra specification in a mid-life facelift.
The 3.0-litre V6 TDI benefits from a slight power increase from 258PS to 262PS and a reduction in CO2 output from 155g/km to 149g/km (in conjunction with 18-inch wheel), equating to a combined economy figure of 49.6mpg.
The 4.2-litre V8 TDI sees economy of 39.2mpg, with CO2 output in this version falling from 194g/km to 189g/km.
The two TDI engines can be complemented by three levels of specification - SE, SE Executive and a new Sport option, which is reserved for standard wheelbase versions and replaces the Sport Executive trim in the outgoing range.
SE trim includes Valcona leather upholstery, double glazing and a 180-watt audio system, combined with technology including all-LED headlights, HDD satellite navigation and the fingertip-sensitive MMI Touch infotainment control system.
SE Executive versions add features such as the Audi parking system advanced with reversing camera, advanced key, and powered, hands-free bootlid operation. New additions at this level include powered door closure, comfort front seats with 22-way powered adjustment and memory function and privacy glass for the rear windows.
Inside the Sport trim level, a 600-watt Bose sound system upgrade and Mobile Phone Preparation - High with Audi connect bring in-car internet-based services, with a mobile Wi-Fi hotspot also available.
The first versions of the updated A8 range can be ordered now priced from £59,585, and the new Sport models from June. UK deliveries will start in the summer.
