Audi's next A5 is expected to land in 2015, and new reports suggest buyers can look forward to a significant drop in weight - and a new e-tron hybrid option.
Riding on a revised 'Evo' version of the Volkswagen Group's MLB architecture, the A5 will benefit from more lightweight materials, lowering kerb weight by around 100kg.
US mag Automobile reports that further reductions will be achievable with an optional Ultra pack, which will bring a lighter air conditioning compressor, alternator, hollow-spoke wheels, and further use of aluminium in the body.
Driveline options are said to include upgraded versions of existing VW/Audi, but a new eight-speed (up from seven) dual-clutch S tronic auto is expected, along with the plug-in hybrid drivetrain option.
This expected e-tron badged plug-in hybrid is likely to emulate the A5 e-tron quattro prototype revealed in 2011, which combined a 157kW 2.0 litre petrol engine with a 35kW electric motor up front, and a second 60kW electric motor driving the rear wheels.
The report adds that next-generation RS 5 performance flagship is likely to use twin turbos in place of the current naturally aspirated 4.2 litre V8.
