The 1.4 TFSI comes with the features common to all A4s. Spend more for a 2.0 TFSI, 2.0 TDI quattro or 2.0 TFSI quattro and you get a more powerful engine (as described above), all-wheel drive (in the quattros), and some different equipment. You can also order the 2.0 TFSI or TFSI quattro as a wagon.
The 2.0 TFSI brings you keyless entry and start (so that you can unlock the car and drive away without taking the key from your pocket or bag). A foot-operated sensor opens the boot hands-free. The front passenger joins the driver in having powered seat adjustment, and digital reception is added to the radio.
Either the 2.0 TDI quattro or the 2.0 TFSI quattro get you, in addition, a memory for the driver’s seat adjustment and for the external rear-view mirrors (so that you can restore your preferred settings quickly after a companion has driven the car). A better sound system in these includes a subwoofer. And both drive all four wheels.
Most of these extra features can be added to the less costly versions at extra cost. And as usual with an Audi there is a vast array of additional extra-cost options, some available individually and others combined in packages.
The most helpful of these is Adaptive suspension, which comes in either comfort or sport form, the former also lowering the car by 10mm and the latter by 23mm. Either way, no A4 should be without these electromagnetically adjusting dampers – they complete the car.
(There is also a Sports suspension option, which lowers the car 20mm but does not have the Adaptive dampers.)
Full leather upholstery is an extra-cost option on an A4, and Audi offers several choices (including the soft Nappa variety). You can also get heating and ventilation for the front seats.
The Technik Package brings you Audi’s virtual cockpit, introducing an expansive, 12.3-inch high-res colour display, in the instrument binnacle ahead of the driver, that replaces conventional dials. Multi-configurable, it is like a desktop for important vehicle functions, including sat-nav mapping, audio, and climate control. In addition, a head-up display projects speed and other information onto the windscreen, so that you can read it without taking your eyes from the road.
You can also add active driving aids, an area where the A4 excels, with Assistance Package Tour. The most outstanding element here takes the lengthy title Adaptive cruise control with stop and go including traffic jam assistant. This brings you radar-guided cruise control, which maintains a set distance to the car in front. Stop and go will control your speed automatically in stop-start traffic, while Traffic jam assistant will gently steer the car for you in those conditions.
A sunroof, rear-seat entertainment tablets, and a wheel upsize to 20-inches diameter are among other choices. Matrix headlights shine into corners and (automatically) dip only a part of their high beams for oncoming drivers, continuing to illuminate outer parts of the roadway. Parking Assistance provides hands-free help with perpendicular and parallel parking.
