The design of the new Audi A6 embodies athleticism and elegance. The sedan is 4.92 meters (16.14 ft) long and 1.87 meters (6.14 ft) wide, but just 1.46 meters (4.79 ft) high - sporty proportions that are unrivaled by the competition. The long engine hood, the low, sweeping roofline and the prominent lines on the flanks create a dynamic overall appearance. Optional LED headlights emphasize the striking expression at the front.
The roomy interior of the new Audi A6 echoes the sinewy style of the exterior. The salient element is the "wrap-around" - an inlay encircling the driver and the front-seat passenger. The elegantly curved dash panel places the driver at the center of the interior.The new Audi A6 features the logical ergonomics concept that distinguishes all of the brand's models. A highly efficient automatic air conditioning system and the latest-generation MMI radio operating system are standard; Audi also offers an optional head-up display, which projects important information onto the windshield. The MMI touch operating system is also available as an option. This enables much of the hard-drive MMI navigation plus system to be controlled by means of a touchpad.
The online services, developed though a partnership between Audi and service provider Google, connect the full-sized sedan to the Internet via the Bluetooth car phone online. A UMTS module pulls images and information from Google Earth up on the monitor and integrates them with the navigation route. A WLAN hotspot provides contact to mobile terminals on board. The top of the hi-fi line is the Bang & Olufsen Advanced Sound System.
MMI navigation plus works closely together with the optional assistance and safety systems in the new A6. It forwards the route data to the control units for the headlights, the automatic transmission and the adaptive cruise control with stop & go function. This enables these systems to recognize complex scenarios and assist the driver. In many situations, the Audi pre sense safety system is able to reduce accidents and their consequences, or even prevent them altogether. The Audi active lane assist helps the driver keep the Audi A6 on course, and the park assist system relieves the driver of the chore of steering when parallel parking.
Audi offers the A6 with a choice of five powerful, highly efficient engines: two gasoline engines and three TDI units. These powerplants develop between 130 kW (177 hp) and 220 kW (300 hp). All of these engines make use of important technologies from the brand's modular efficiency platform - the start-stop system, the energy recovery system, and the innovative thermal management concept.The most powerful unit in the range is the 2.0 TDI. In conjunction with a manual transmission, it requires on average just 4.9 liters of fuel per 100 km (48.00 US mpg) and emits just 129 g CO2 per km (207.61 g/mile). The Audi A6 hybrid will be available from Audi at a later date. Serving up 180 kW (245 hp) of system performance, its 2.0 TFSI plus electric motor will achieve efficient and sporty acceleration with an average fuel consumption of only 6.2 liters per 100 km (37.94 US mpg) (provisional figure).
Depending on the engine version, power is funneled via the gears to the front wheels or to the quattro permanent all-wheel drive, whose crown-gear center differential and torque-vectoring function achieve the ultimate traction, stability and dynamic response. For the top-of-the-line engines, Audi will offer an optional sport differential.
The chassis of the new A6 combines sporty precision with supreme comfort. Its links are made of aluminum; the redesigned power steering features a highly efficient electromechanical drive. The executive sedan has wheels ranging from 16 to 20 inches in diameter.
The Audi drive select dynamic handling system is standard, and the front-wheel-drive models have the sporty ESP with electronic limited-slip differential on board. For enhanced comfort, adaptive air suspension with controlled damping is available as an option. Dynamic steering will be available soon, also as an option.
Audi is launching the A6 with a choice of powerful, sophisticated, and highly efficient four- and six-cylinder powerplants: two gasoline engines and three TDI units. They have outputs ranging from 130 kW (177 hp) to 220 kW (300 hp). They obtain their fuel through direct injection; the 3.0 TFSI employs a supercharger to achieve boost, and the 2.0 TFSI and TDI operate with turbochargers.
Each of these engines makes use of technologies from the Audi modular efficiency platform. Much effort has gone into optimizing these engines, particularly with regard to internal friction, in keeping with the brand's innovative thermal management system. Each of the units operates with an energy recovery system combined with a start-stop system, irrespective of the type of transmission used.
The new Audi A6 is setting the standard for efficiency in the executive class. Throughout the entire model line, fuel consumption in the Audi A6 has decreased by up to 19 percent compared with the previous models - even as its performance has increased. The 2.0 TDI requires on average just 4.9 liters of fuel per 100 km (48.00 US mpg) and emits only 129 g CO2 per km (207.61 g/mile).
The most powerful gasoline engine in the A6 family is the 3.0 TFSI; its mechanical charger is situated in the 90-degree V formed by the cylinder banks. The V6 delivers 220 kW (300 hp) of power and 440 Nm (324.53 lb-ft) of torque, the latter at 2,900 to 4,500 rpm. The Audi A6 3.0 TFSI sprints from standing to backroad speed in 5.5 seconds and reaches an electronically governed top speed of 250 km/h (155.34 mph). It consumes on average 8.2 liters per 100 km (26.68 US mpg) and emits 190 g CO2 per km (305.78 g/mile) - an advance of 13 percent over the previous model, which produced 213 kW (290 hp).
The most efficient engine in the new A6 is the redeveloped 2.0 TDI. This four-cylinder unit develops 130 kW (177 hp). Its 380 Nm (280.27 lb-ft) of torque stand at the ready between 1,750 and 2,500 rpm. In conjunction with a manual transmission, it propels the Audi A6 from zero to 100 km/h (62.14 mph) in 8.7 seconds, then on to a top speed of 228 km/h (141.67 mph). In the EU cycle, it requires just 4.9 liters per 100 km (48.00 US mpg) and emits only 129 g CO2 per km (207.61 g/mile). That is a 13 percent decrease in fuel consumption.
In the first version, the V6 diesel generates 150 kW (204 hp) and applies 400 Nm (295.02 lb-ft) of torque in the low range of 1,250 to 3,500 rpm. Paired with a multitronic transmission, it accelerates the A6 to 100 km/h (62.14 mph) in 7.2 seconds and achieves a top speed of 240 km/h (149.13 mph). Its average consumption is a mere 5.2 liters per 100 km, a CO2 emissions level of 137 g per km (220.48 g/mile). Compared with the 140 kW (190 hp) predecessor, this represents an advance of 19 percent.
The top-of-the-line version of the 3.0 TDI delivers 180 kW (245 hp), providing 500 Nm (368.78 lb-ft) of torque between 1,400 and 3,250 revolutions. The standard sprint takes just 6.1 seconds, and top speed is limited to 250 km/h (155.34 mph). On average, this top-performing diesel powerplant uses just 6.0 liters of fuel per 100 km (39.20 US mpg) and emits 158 g CO2 per km (254.28 g/mile). As such it outperforms the previous engine, which achieved 176 kW (240 hp), by 16 percent.
As was the case with the previous model, the new Audi A6 is also available with a wide range of drivetrains. Depending on the engine version, these include front-wheel drive and quattro drive, the manual six-speed transmission, the continuously variable multitronic, and the seven-speed S tronic - the lightning fast dual-clutch transmission is a new addition to the large series. Audi offers optional shift paddles.
The transmissions are a major factor in the efficiency of the new A6. They stand out due to their low internal friction and high efficiency; with their wide gear-ratio spread, they are high geared for high speeds. The automatic transmissions have access to predictive route data from the navigation systems and are integrated into the engine's thermal management system. The differential is in front of the clutch and immediately behind the engine. Accordingly, the front axle on the Audi A6 is positioned farther forward, making for a long wheelbase and a harmonious axle load distribution.
The four-cylinder TDI transfers its power to the front wheels. It is fitted as standard with a manual transmission or, alternatively, with the multitronic. These transmissions are also available for the front-wheel-drive version of the 2.8 FSI. The manual transmission will also be available soon after for the 150 kW (204 hp) 3.0 TDI. The FSI gasoline engine can also be coupled with quattro permanent all-wheel drive and the S tronic. The 3.0 TFSI and the 180 kW (245 hp) 3.0 TDI come with a standard all-wheel drive, always in combination with the S tronic.
All quattro versions of the new A6 implement the latest development stage of the permanent all-wheel drive with the crown-gear center differential. This system distributes power in an especially flexible, dynamic manner, while also featuring a compact, lightweight construction. The basic ratio of power distribution between the front and rear axle is 40:60 - a sporty, rear-biased characteristic.
The new quattro drivetrain features the integrated torque-vectoring function, which recognizes when the inside wheels are about to lose their grip during fast cornering. Before this can happen, it brakes the wheel very slightly - almost imperceptibly - making the handling even more fluid and traction even stronger. Rounding off the top-of-the-line version, Audi offers the optional sport differential, which actively distributes the power between the rear wheels.
The chassis of the new Audi A6 combines sporty precision with supreme comfort. The wheel control arms and many other components are made of lightweight aluminum. Each of the front wheels is guided by five control arms, with self-tracking trapezoidal-link suspension operating at the rear.
The standard alloy wheels are 16 or 17 inches in diameter, depending on the engine version. Audi and quattro GmbH offer wheels with up to 20-inch rims as an option. Tire formats ranging from 225/60 to 265/35. A tire-pressure monitor display is standard, and certain tires can be optionally equipped with emergency running properties.
The four disk brakes - internally ventilated at the front - are generously sized and powerful. The brake light operates on an adaptive principle; when the brakes are fully applied, it warns the traffic behind by pulsating rapidly.
The redesigned power steering has an electromechanical drive that operates in a highly efficient manner. The degree of support it provides is based on the speed. With a ratio of 16.1:1, the steering is sporty and direct, providing precise feedback from the road. It cooperates closely with the optional Audi active lane assist system and also proves useful with braking when the car has traction on only one side: The steering impulses it gives in this case make it easier for the driver to steer in the right direction.
Audi has equipped the new A6 with steel springs that ensure a high level of ride comfort. Sport suspension as well as S line sport suspension from quattro GmbH are alternative options. Air suspension with four electronically controlled shock absorbers is also optionally available. The adaptive air suspension has been redesigned, with spring struts up front and separate air springs and dampers in the back. The system sets the ride height of the body to one of three levels. On the highway, it lowers the body, increasing stability and decreasing fuel consumption.
All front-wheel drive models of the Audi A6 have the ESP electronic stabilization program with electronic limited-slip differential on board. This software solution operates much like the torque-vectoring function in the quattro train; however, it focuses its light brake applications solely on the inside front wheel. This braking action ensures that the sedan remains neutral longer during fast cornering, practically eliminating understeering, improving grip, and making handling more dynamic.
Among the high-end solutions in the new A6 is the Audi drive select dynamic handling system. In its standard version, it controls the engine management, power steering, and the automatic air conditioning system. The driver can vary the function of these components between the five modes "comfort," "auto," "dynamic," "individual," and "efficiency." For all TFSI and TDI models, the "efficiency" operating level supports a driving style that provides for optimum fuel consumption by customizing the characteristics of various vehicle systems.
Audi A6 customers can expand the system to include the automatic transmission, adaptive air suspension, ACC with stop & go function, adaptive lights, and ambient lighting options. Soon to come are the sport differential and dynamic steering, which varies its ratio according to the speed at which the car is traveling.
The new Audi A6 will arrive at dealerships with an array of standard equipment, including the Audi pre sense basic system, alloy wheels, the high-efficiency two-zone automatic air conditioning system, the front center armrest, the engine start-stop button, the tire pressure monitoring system, the adaptive brake light, the MMI radio complete with 6.5-inch monitor, and the electromechanical parking brake. The safety package consists of two front, side and head airbags, four belt tensioners, and the integral Audi head restraint system.
The portfolio of new assistance, safety, and infotainment systems is particularly attractive. In terms of music, a number of components are available, such as a DVD changer, a digital radio tuner, the Audi music interface for integrating a mobile player, a TV module, and the Bose surround sound system. The pinnacle of all sound systems is the 1,300-watt Advanced Sound System from Bang & Olufsen. Its 15 speakers, which include two acoustic lenses that extend from the instrument panel when the system is switched on, have elegant housings made of aluminum.
The optional Bluetooth car phone online connects the executive sedan to the Internet, in partnership with service provider Google. A UMTS module allows the car to retrieve news, weather, and travel information; it also pulls images and information from Google Earth up on the monitor and integrates them with the navigation route. A WLAN hotspot provides contact to mobile terminals on board. Drivers can make use of all these services with their mobile phone contract; the services are charged via the SIM card, which in many cases already has a flat-rate plan.
The MMI radio and CD drive are standard in the infotainment systems in the new Audi A6. Available options include the MMI radio plus, MMI navigation, and MMI navigation plus with MMI touch. The top-of-the-line version offers, among others, a 3D graphics chip for an elegant map display, a high-resolution eight-inch color monitor, a large hard disk, a convenient voice control system, and a Bluetooth interface.
The groundbreaking feature of MMI navigation plus is the touchpad - MMI touch. It allows the driver to perform a great many functions easily and intuitively, for example, writing the digits of telephone numbers and the letters of the navigation destination with a finger or scrolling lists and maps. The driver's eyes can stay on the road because the system acknowledges every input acoustically. MMI touch also recognizes the characters of Asian languages. When the driver is not using the touchpad to enter data, it turns into a radio keypad with six station buttons.
MMI navigation plus in the new Audi A6 is closely networked with the optional assistance and safety systems. Data from the route is utilized in the control units for the headlights, the automatic transmission, and the adaptive cruise control with stop & go function. This enables these systems to recognize complex scenarios and predictively assist the driver.
The Audi pre sense safety system is available in various versions. In many situations, it is able to minimize accidents and their consequences, or even prevent them altogether, by warning the driver and applying the brakes with increasing force to slow the sedan down in an emergency.
At the same time, the system closes the windows and the sunroof, tightens the seat belts, activates the hazard warning lights, and stiffens the dampers of the optional adaptive air suspension.
Audi pre sense front works closely with the adaptive cruise control with stop & go function. The radar-based distance control accelerates the new A6 and decelerates it within certain limits. The system uses the data from two radar sensors, a video camera and the ultrasonic sensors, incorporates navigation data, and analyzes a multitude of additional signals. With its precisely variable function, the range of use of the ACC stop & go extends from rolling in city traffic all the way to top speeds.
The new Audi active lane assist helps the driver keep the Audi A6 on course with ease at speeds of 60 km/h (37.28 mph) and above. A camera detects the lines on the road; if the sedan crosses over one of them, the system guides it back by gently intervening in the steering.
The parking system, also new, takes over steering from the driver when parallel parking or parking perpendicular to the road. It detects suitable spaces and automatically guides the A6 into and back out of parallel parking spaces - in several moves, if necessary. Alternatively, Audi also offers conventional parking assistance with and without a reversing camera.
At speeds of 30 km/h (18.64 mph) and above, Audi side assist observes the area behind the sedan via radar, thereby ensuring it is safe to change lanes. The speed limit display detects important speed restrictions and shows them in the driver information system or on the optional head-up display. Night vision assistant works with a thermal-imaging camera. It projects its black-and-white images onto the display of the driver information system, highlighting any pedestrians it detects in front of the vehicle. If it anticipates a potential dangerous situation, it highlights the pedestrian in red.
