Audi will offer its fifth-generation A4, due in 2015, with three new plug-in hybrid drivetrains.
The move is a bid to pitch the model as the most high-tech and fuel-efficient car in the fiercely competitive compact executive segment.
Petrol-electric and diesel-electric plug-in hybrids will be offered in the new BMW 3-series rival, featuring latest-generation four-wheel drive, eight-speed automatic gearboxes and an electric-only range of up to 31 miles.
The new A4, codenamed B9, is also set to become the first conventional steel monocoque Audi model to use the company’s MLB (modular longitudinal architecture) platform to significantly benefit from a range of weight-saving initiatives, including aluminium panels. Sources report a 100kg reduction in kerb weight for the base-level A4, droppping it to 1330kg.
New saloon and Avant models of the A4 are due to reach the UK in April 2015, with an Allroad variant to follow later in the year. Successors to the A5 coupé, cabriolet and Sportback will follow in 2016.
The car has been styled under the direction of Audi design boss Wolfgang Egger. Insiders privy to the final design say it will be evolutionary, albeit with heavily updated detailing.
Distinguishing features include a newly styled 3D-effect single-frame grille, trapezoidal LED headlamps, more heavily creased bumpers and a prominent shoulder line running the length of the flanks. Sharper creases will also feature on the bodywork.
