Audi has unveiled the fifth-generation A4 ahead of its public debut at the Frankfurt Motor Show in September.
Typical to Audi, the design is evolutionary with a more formal look and no big surprises, featuring also new technology, newly developed chassis and upgraded petrol and diesel engines.
Going against the BMW 3 Series and Mercedes-Benz C-Class, the design is highlighted by a wider single-frame grille, new headlight shape with revised LED daytime running light graphics, a clamshell-style bonnet, larger wheelhouses, a flatter roof, sharper LED tail-lights and a higher boot lid.
The new A4 also has a class-leading drag co-efficient of 0.23 for the saloon.
Compared to the outgoing model, the new A4 has grown a little and has a length of 4726mm, width of 1842mm and height of 1427mm, making it 25mm longer and 16mm wider. The height remains the same, while the wheelbase has grown by 12mm to 2820mm.
Even though it is slightly bigger, the weight has been reduced by up to 120kg, depending on the model thanks to hot-formed high-strength steel and aluminium.
The interior now offers additional 24mm of head room and 11mm more shoulder room up front, while there is also 23mm increase in rear seat legroom.
Boot space is up by 15 litres, standing now at 505 litres, increasing to 1510 litres when the split rear seat is folded away.
Some of the technology goodies include optional 12.3-inch digital instrument panel, inductive charging pad for mobile phones, sensor control opening of the luggage compartment, a Bang & Olufsen sound system, tablet-based rear seat entertainment.
From launch the engine line-up will include three turbocharged four-cylinder petrol, two four-cylinder diesel and two V6 diesel engines, offering up to 25 per cent more power and a fuel economy improvement of up to 21 per cent.
The range offers power from 148bhp to 272bhp. The most economical choice will be a 148bhp 2.0-litre four-cylinder diesel unit in the Ultra model, returning 76.4mpg and CO2 emissions of 95g/km.
Fifth-generation A4 is due on sale this fall, with Allroad and RS4 models to follow later.
