A handful of 2016 Audi A4 prototypes have been spied undergoing testing in Europe.

Set to be unveiled later this year, the redesigned A4 has a familiar shape but it is expected to be larger than its predecessor to help distance itself from the a new A3 sedan.  The model also features a more prominent grille and distinctive headlights that have a controversial cutout.

Moving on to the interior, owners can expect to find a more upscale cabin with higher quality materials and an improved design.  Notable highlights include a three-spoke steering wheel, metallic accents, an improved infotainment system and a new shifter that mimics the one in the A8.

Under the hood, there will be an assortment of new and improved engines including the new 2.0-liter TSFI petrol engine that was introduced earlier today.  It will produce 190 PS (140 kW) and 320 Nm (236 lb-ft) of torque and enable the model to return 5 L/100km (47 mpg US / 56.5 mpg UK).
