Have you ever heard about Audi’s 360o design philosophy? Well, allow us to explain with an example. In its more recent incarnation, it goes something like this: the latest A4 [B8] provided the styling guidelines for the creation of the new 2011MY A8 which itself inspired the design of the new 2012MY A6, which has now become the inspiration for the updated A4…

So that probably gives you an idea about the styling changes for the 2013MY Audi A4 in both sedan and Avant forms as well as its S4 and A4 Allroad Quattro siblings.

In a similar fashion to the recently updated A5/S5 models, the refreshed A4s gain Audi’s new six-point grille and sharper looking headlamps with LED daytime running lights that form a narrow band, redesigned front and rear bumpers, plus tweaked tail lights that reflect the shape of the head lights and come with LED strips.

The exterior modifications have slightly altered the dimensions of the A4, with the sedan and Avant now measuring 4.70 meters (15.42 ft) in length, and the Allroad Quattro and S4, 4.72 meters (15.49 ft). The wheelbases for all variants is 2.81 meters (9.22 ft), and the width is 1.83 and 1.84 meters, respectively (6.0 and 6.04 ft), while the height varies between 1.41 and 1.50 meters (4.63 and 4.92 ft) depending on the version.

Audi’s designers refined the A4’s interior with a new selection of steering wheel designs and fresh color options, while the company also made changes to the steering arm and the ignition key.

On the engine front, Audi says consumption levels have dropped by 11 percent on average, despite the increased power and torque of many of the engines.

In Europe, the A4 sedan and Avant will be offered with a new 1.8-liter TFSI petrol that delivers 170HP and 320 Nm (236.02 lb-ft) of torque. In the sedan, it returns a combined fuel economy of 5.6 lt/100km (42.0 US mpg) with CO2 emission of 134 grams per km (215.65 g/mile), which represents a 19 percent decrease in consumption compared with the previous engine.

The updated 2.0-liter TDI is offered in three states of tune producing 136HP (100kW), 163HP (120kW) and 177HP (130kW). The 136HP version is the most fuel-efficient delivering an average consumption of 4.2 lt/100 km (56.0 US mpg) with CO2 emissions of 112 grams per km (180.25 g/mile).

The most potent engine available in the series is the 3.0-liter V6 TFSI that produces 272HP in the A4 and 333HP in the S4. The latter is available in both sedan and Avant variants. The S4 sedan goes from zero to 100km/h (62mph) in 5.0 seconds and reaches an electronically limited top speed of 250 km/h (155 mph) while returning an average fuel consumption of 8.0 liters per 100 km (29.40 US mpg).

A six-speed manual gearbox is standard on the A4 Sedan and Avant models with front-wheel drive, with most variants offering an optional continuously variable multitronic transmission. The quattro versions come with either a manual gearbox or the seven-speed S tronic double-clutch transmission. The A4 Allroad Quattro employs a manual transmission or S tronic with all engine variants.

Audi added that the mounts of the rear suspension control arms are new and the characteristics of the shock absorbers have been re-tuned while the electromechanical power steering is also new in all models of the A4 series.
