The Audi A4: Even Sportier and More Modern
The A4 represents the core of the brand – after four years in the making, Audi has made the successful midsize model even tauter and sportier. Its exterior is shaped by the brand’s new design language, while the large MMI touch display offers the kind of operating experience customers will be familiar with from their smartphone. Many engine variants now come with mild hybrid systems (MHEV) – efficiency and comfort benefit from this broad-based electrification. This also applies to the Audi S4 TDI (combined fuel consumption in l/100 km: 6.3–6.2* (37.3–37.9 US mpg); Combined CO2 emissions in g/km: 166–163* (267.2–262.3 g/mi)) with a V6 TDI under the hood for the first time, a 48-volt main on-board electrical system and an electric powered compressor that lends its hefty acceleration even more spontaneity. This combination of power, torque and efficiency makes it unique in its segment.
Sporty look: the exterior design
The midsize model looks even more dynamic and sophisticated thanks to the sportier design highlights. The Singleframe grille is now broader and flatter; horizontal lines emphasize the width at the front and rear. The side view is defined by the distinctive muscles above the fenders and the lower set shoulder line in between. They form strong contours above the wheels and make the quattro genes outwardly visible.
LED headlights now come as standard in the Audi A4; the top-of-the-line headlights feature the Matrix LED technology with fully automatic high beam. The equipment line concept is equally new: basic, advanced and S line are now available for the exterior, not to mention the independent look of the A4 allroad quattro and the S models. Customers can choose from 12 exterior colors, including a new terra gray option.
In the cleanly drawn interior of the Audi A4, the horizontal lines also define the overall impression. In the center of the instrument panel, slightly tilted toward the driver, is the large MMI touch display, the control center for the new operating system. The new interior packages – design selection and interior S line – can be combined freely with the exterior lines and come with numerous colors and materials. The contour/ambient lighting package adds highlights to the interior in the dark.
With its new MMI system, the highly connected Audi A4 offers a user experience similar to a contemporary smartphone. An MMI touch display with acoustic feedback takes over the functions of the previous rotary/pushbutton control on the center tunnel console. The high- resolution TFT display measures 10.1 inches. Its graphics are deliberately clean and cut-down; the menu structure with its tight hierarchies is tailored to user expectations and aims for easy operation. The MMI search
is based on free text input and returns hits rapidly.
The natural-language voice control, another function of the new system, understands many of the phrases used in everyday speech.
The navigation in the Audi A4 is now even more versatile and user-friendly. The Audi connect and Audi connect plus portfolio includes a host of online services, such as Car-to-X services, which take advantage of the swarm intelligence of the Audi fleet. Apart from online traffic sign and hazard information, as well as the on-street parking service, traffic light information is a new addition to the lineup. Thanks to the interconnection with the city’s infrastructure, the vehicle receives information from the central traffic light computer via a server, which allows the driver to select a speed to match the next green-light phase. The instrument cluster displays a personal speed recommendation as well as the remaining time to the next green light whenever the driver is waiting at a red traffic light. The system thus contributes to a predictive and efficient driving style and facilitates a steady flow of traffic. The function is part of the Audi connect package and is being rolled out in stages in selected European cities.
The Audi connect services emergency call and service come as standard; the free myAudi app connects the customer’s smartphone seamlessly to the car. With the Audi connect key option, the customer can lock and unlock the vehicle and start the engine using a compatible Android smartphone. The personalization, another digital feature that starts shortly after market introduction, allows up to 14 myAudi users to store their preferred settings in individual profiles.
The pioneering functions on demand are part of the many innovations set to accompany the market launch of the Audi A4. They allow customers to add on three infotainment functions flexibly as required via the myAudi app, even after purchasing the vehicle. In Germany, these are the MMI navigation plus, the DAB+ digital radio and the Audi smartphone interface. There is a choice of various terms.
If customers would like to get to know a function first before committing themselves, they can book a one-time, one-month test phase. Customers can extend the booking even during this phase, either for a further month, a year, or permanently. If they decide not to extend the term, the booking expires automatically and without requiring active termination at the end of the term.
The new MMI features a new main unit. The third-generation modular infotainment platform MIB 3 delivers phenomenal computing power. It works with an equally new, physically separate communication box that bundles all connectivity tasks – such as telephony or the Audi connect services – and incorporates the Wi-Fi hotspot. The optional hardware modules include the Audi phone box and the Bang & Olufsen 3D Premium Sound System in the front.
Three instrument cluster variants are available: two partially analog driver information systems and – in conjunction with the MMI navigation plus – the all-digital Audi virtual cockpit plus. The driver operates the 12.3-inch display with full HD resolution using the multifunction steering wheel and can choose between three views. A head-up display
projects important information into the driver’s direct field of view.
The A4 models are available with a host of driver assistance systems. The optional systems are bundled into the “Tour,” “City” and “Park” packages. An important system in the “Tour” package is the adaptive cruise control including stop & go function for automatic distance control. In conjunction with the predictive efficiency assist
, it can brake and accelerate the A4 predictively even where there is no vehicle ahead. To do so, it analyzes Car-to-X messages, navigation data and traffic signs.
Broad-based electrification: the drive
Audi will be offering the A4 product line with eight turbocharged engines at sales launch in Europe. Their power outputs range from 100 kW (136 metric hp) to 255 kW (347 metric hp) – from the Audi A4 35 TFSI up to the Audi S4 TDI. All engines – whether four-cylinder diesel unit, V6 TDI or four-cylinder TFSI – are below the limits of the Euro 6d-temp emission standard.
For the market introduction, five engine variants will feature a mild hybrid system (MHEV) based on 12 volts, which reduces fuel consumption while improving comfort. This broad-based electrification makes an important contribution to increasing efficiency and saving fuel for the benefit of the customer, and thereby also helps to achieve the fleet targets for CO2. In everyday operation, the MHEV system reduces fuel consumption by up to 0.3 liters per 100 kilometers according to individual Audi measurements.
Whether manual transmission, seven-speed S tronic or eight-speed tiptronic, whether front- wheel or quattro drive – each of the eight engine variants delivers tailor-made power transmission. At market launch, all A4 models will be manufactured with an automatic transmission. The A4 35 TFSI with 110 kW (150 metric hp) (combined fuel consumption in l/100 km: 6.5–5.7* (36.2–41.3 US mpg); combined CO2 emissions in g/km: 143–129* (230.1–207.6 g/mi)) of power output is also available with a manual transmission.
Sportily harmonious: the suspension
The sportily balanced suspension harmonizes ideally with the character of the Audi A4. Customers can choose between the standard setup and the sport suspension. There are also two adaptive suspensions. One option is the comfort suspension with damper control, which reduces the ride height by 10 millimeters (0.4 in) and offers superb ride comfort. The other is the sport suspension, either with or without damper control, which is lowered by 23 millimeters (0.9 in). With its even more dynamic basic setup, it underscores the sporty character while maintaining comfort.
Both controlled suspensions are integrated into the Audi drive select dynamic handling system. The same applies to the steering or the optional dynamic steering as well as the automatic transmission and also the engine management system. Audi drive select allows the driver to determine which of up to five profiles these systems use.
Diesel power: the Audi S4 TDI
Both S models of the A4 family are now equipped with a V6 diesel engine as a power package. The 3.0 TDI combines hefty torque, smooth running and a long range and delivers a power output of up to 255 kW (347 metric hp) and maximum torque of 700 Nm (516.3 lb-ft) to the Audi S4 Sedan TDI (combined fuel consumption in l/100 km: 6.3–6.2* (37.3–37.9 US mpg); combined CO2 emissions in g/km: 164–163* (263.9–262.3 g/mi)) and the S4 Avant TDI(combined fuel consumption in l/100 km: 6.3* (37.3 US mpg); combined CO2 emissions in g/km:166–165* (267.2–265.5 g/mi)). It propels the S4 Sedan TDI from 0 to 100 km/h (62.1 mph) in 4.8 seconds and up to an electronically governed top speed of 250 km/h (155.3 mph). This combination of power, torque and efficiency makes the Audi S4 TDI unique in the segment.
The electric powered compressor (EPC) delivers powerful drive-off performance and virtually seamless power buildup when accelerating. As a result, it eliminates any turbo lag, enabling instant responsiveness in all driving situations. The EPC is integrated into a new 48-volt main on- board electrical system that also incorporates the mild hybrid system. This provides even more efficiency potential than the MHEV system in the 12-volt on-board electrical system of the A4 models. In the S4 TDI, this is the next expansion stage in which the mild hybrid technology will be rolled out based on 48 volts. Within that, the 12-volt subsidiary on-board electrical system is connected to the 48-volt main on-board electrical system via a powerful DC/DC converter. For the first time in the S4 TDI, a powerful 48-volt belt alternator starter is the heart of the mild hybrid system with maximum recuperation power during braking of up to 8 kW.
A compact air-cooled lithium-ion battery with a capacity of 0.5 kWh under the luggage compartment floor serves as the energy center. The mild hybrid system in the S models has the potential to reduce customer fuel consumption by as much as 0.4 liters per 100 kilometers.
An eight-speed tiptronic and the quattro permanent all-wheel drive make up the powertrain. If desired, an optional sport differential is available to actively distribute power between the rear wheels. In this way, more power can be directed specifically to the wheel on the outside of the bend when cornering at speed, which combats the tendency to understeer early on. The S sport suspension comes as standard. With its S-specific setup, it provides a sporty driving sensation. This can be enhanced even further with the optional S sport suspension with damper control. Inside and out, a host of design details point to the unique position of the S models – from the exhaust tailpipes to the S mode in the display of the optional Audi virtual cockpit.
The consummate on-road and off-road experience: the Audi A4 allroad quattro
Thanks to its quattro all-wheel drive and ground clearance raised by 35 millimeters (1.4 in), the Audi A4 allroad quattro combines superb ride comfort and good off-road qualities. With the optional allroad-specific suspension with damper control, comfort and dynamism can be enhanced further. It differs from the A4 Avant through details such as the underbody protection or the wheel arch trims and also by its 12-millimeter (0.5 in) larger wheels and its wider track – six millimeters (0.2 in) wider at the front and eleven millimeters wider (0.4 in) at the rear.
The A4 allroad quattro is available with a gasoline engine and as a diesel variant. Automatic transmissions come as standard, while a suspension with damper control provides an alternative to the standard suspension. As in the A4 Avant, the luggage compartment has a capacity of 495 liters (17.5 cu ft) – this increases to 1,495 liters (52.8 cu ft) with the rear seats folded down and cargo loaded to the roof. The luggage compartment lid and the luggage compartment cover are electrically operated as standard. With the additional off-road mode of the Audi drive select dynamic handling system, the driver can choose from a total of six profiles in the A4 allroad quattro.
For more spontaneous buyers: the Audi A4 edition one model
To coincide with the market launch, the brand with the four rings is presenting an A4 edition model designated “edition one.” The exterior design is based on the S line exterior, supplemented with striking elements such as the black styling package. In the interior, the customer can choose between the design selection and the S line interior package. The “edition one” is available as a Sedan or Avant with a choice of three engine variants – the 2.0-liter TFSI with a power output of 180 kW (245 metric hp) (combined fuel consumption in l/100 km: 6.9–6.5* (34.1–36.2 US mpg); combined CO2 emissions in g/km: 157–146* (252.7–235.0 g/mi)), the 2.0-liter TDI with 140 kW (190 metric hp) (combined fuel consumption in l/100 km: 5.3–4.9* (44.4–48.0 US mpg); combined CO2 emissions in g/km: 140–131* (225.3–210.8 g/mi)) and a 3.0-liter TDI with 170 kW (231 metric hp) (combined fuel consumption in l/100 km: 5.6–5.3* (42.0–44.4 US mpg); combined CO2 emissions in g/km: 145–139* (233.4–223.7)).
