2016 Audi A6 L e-tron unveiled in China

Article by Christian Andrei, on April 20, 2015

Audi has announced that local production of the A6 L e-tron in China will start in 2016. The very fuel-efficient and powerful A6 L e-tron sedan was developed especially for the market in China. The plug-in hybrid drive produces 180 kW (245 hp) and boasts an average fuel consumption of only 2.2 liters of fuel per 100 kilometers (106.9 US mpg).

The automaker had launched the e-tron era in the Chinese market with the imported A3 Sportback e-tron in 2015. The A6 L e-tron is derived from the long version of the Audi A6, which is already in production in China. It has the configuration of a very efficient parallel hybrid, which means that its two drives are positioned one directly at the back of the other.

The 2.0 TFSI is a highly advanced, four-cylinder gasoline engine that can deliver 155 kW (211 hp) and 350 Nm (258.1 lb-ft) of torque. It is equipped with a disk-shaped electric motor that produces 91 kW and 220 Nm (162.3 lb-ft) of torque. When working with a decoupler, this is integrated into the eight-speed tiptronic transmission, shifting the power to the front wheels.

It has a system output of 180 kW (245 hp) and has a maximum system torque of 500 Nm (368.8 lb-ft). A sporty performance is delivered by the Audi A6 L e-tron, which has a curb weight of slightly above 2,000 kilograms (4,409.2 lb). Sprinting from zero to 100 km/h (62.1 mph) takes only 8.4 seconds. It is capable of reaching a limited top speed of 210 km/h (130.5 mph).

Under China’s way of measuring fuel economy, the Audi A6 L e-tron can consume only 2.2 liters of fuel per 100 kilometers (106.9 US mpg) and has CO2 emissions of 52 grams CO2 per kilometer (83.7 g/mi). On purely electric power, the Audi A6 L e-tron 2.0 TFSI can be driven 50 kilometers (31.1 mi) without local emissions.

This means that it can be considered as what the Chinese refer to as a New Energy Vehicle. It has a total range of 880 kilometers (546.8 mi). It is powered by a 104-cell lithium-ion battery that is capable of storing 14.1 kWh of energy. The battery is placed under the luggage compartment. Its capacity has been slightly reduced to 340 liters (11.9 cu ft).

As a result, the car has enough stowage space for lengthier trips. With the new two-phase charging technology, charging can be done with 7.2 kW of power. It takes around two hours for a full charge if a high-power charging cable is used with the right infrastructure (high-power industrial outlet). But the process takes longer than 8 hours on a typical household outlet in China.

The Audi A6 L e-tron is operated by the intelligent hybrid management system. Four driving modes are available to the driver. The first – the “EV” (electric vehicle) mode -- prioritizes electric driving during speeds of up to 135 km/h (83.9 mph). If the “hybrid” mode is chosen, the hybrid management system determines the drive type to achieve the highest possible efficiency.

If the driver opts for the “battery hold” mode, the system stores electrical energy and the battery is charged in “battery charge” mode. The e-tron is then able to drive in hybrid mode but the two drives deactivate when the driver doesn’t step on the accelerator anymore. When the electric motor assumes most of the braking, the battery gets charged.

It’s only during heavy braking that the hydraulic brakes are activated. Details about the drivetrain and the battery levels are seen on the displays. If you want to know the total system output, just look at the powermeter in the instrument cluster. The hybrid system’s energy flows are seen in the monitor for the MMI navigation plus.

Meanwhile, the driver information system is where the driver can see the range and consumption figures for electricity and gasoline. Audi’s plug-in hybrid models are easy to distinguish if you know what to look out for.

Among the visual cues are a set of 18-inch alloy wheels that have the delicate e-tron design and LED light guides in the air inlets that produce a signature of staggered lines. There are e-tron badges on the fenders and the trunk lid and the exhaust system tailpipes are concealed by the diffuser. [source: Audi]

Press Release

The new Audi A6 L e-tron for China

With the A6 L e-tron, Audi is taking an important step toward even greater fuel efficiency in China. The sedan has been developed specifically for the Chinese market. Its plug-in hybrid drive with 180 kW (245 hp) provides for powerful performance. The model consumes on average just 2.2 liters of fuel per 100 kilometers (106.9 US mpg).

After launching the e-tron era in China with the imported A3 Sportback e-tron* in 2015, Audi is taking the next step with the local production of the A6 L e-tron beginning in 2016. The model is based on the long version of the Audi A6, which is already built in China, and is configured as a highly efficient parallel hybrid, meaning that its two drives are arranged one directly behind the other. The 2.0 TFSI is a state-of-the-art, four-cylinder, gasoline engine producing 155 kW (211 hp) and 350 Nm (258.1 lb-ft) of torque. The disk-shaped electric motor provides 91 kW and 220 Nm (162.3 lb-ft) of torque. Together with a decoupler, this is integrated into the eight-speed tiptronic transmission, which transfers the power to the front wheels. System output is 180 kW (245 hp); maximum system torque is 500 Nm (368.8 lb-ft).

Sporty performance, low consumption
The Audi A6 L e-tron, which has a curb weight of just over 2,000 kilograms (4,409.2 lb), delivers sporty performance: The sprint from 0 to 100 km/h (62.1 mph) takes just 8.4 seconds, and top speed is limited to 210 km/h (130.5 mph). According to the measurement method prescribed in China for plug-in hybrid vehicles, it consumes just 2.2 liters of fuel per 100 kilometers (106.9 US mpg), corresponding to 52 grams CO2 per kilometer (83.7 g/mi). The Audi A6 L e-tron 2.0 TFSI covers 50 kilometers (31.1 mi) purely on electric power and with zero local emissions. It therefore meets the Chinese definition of a New Energy Vehicle. Total range is 880 kilometers (546.8 mi).

Its lithium-ion battery comprises 104 cells and stores 14.1 kWh of energy. Located beneath the luggage compartment, the battery reduces its volume only slightly - capacity is 340 liters (11.9 cu ft). The car thus offers sufficient stowage space for longer trips. The new two-phase charging technology allows charging with 7.2 kW of power. With the appropriate infrastructure (high-power industrial outlet) and high-power charging cable, the batteries can be fully charged in roughly two hours. On a typical household outlet in China, the procedure takes somewhat longer than eight hours, and can thus easily be performed overnight.

Electric driving at up to 135 km/h (83.9 mph)
The intelligent hybrid management system controls the operating states of the Audi A6 L e-tron. The driver can choose between four driving modes. "EV" (electric vehicle) mode prioritizes electric driving at up to 135 km/h (83.9 mph). In "hybrid" mode, the hybrid management system chooses the drive type for the best possible efficiency. In "battery hold" mode, the system stores the available electrical energy and charges the battery in "battery charge" mode. The sedan can coast in hybrid mode - when the driver takes his or her foot off of the accelerator, both drives are deactivated. The electric motor assumes most of the braking, charging the battery. The hydraulic brakes are used only for heavy braking.

Controls and displays
The displays of the Audi A6 L e-tron provide detailed information about the status of the drivetrain and the battery charge. The powermeter in the instrument cluster displays the total system output. The monitor for the MMI navigation plus visualizes the energy flows in the hybrid system; range and consumption figures for electricity and gasoline are displayed in the driver information system.

A number of visual cues identify the plug-in hybrid models from Audi. The 18-inch alloy wheels feature the delicate e-tron design, and LED light guides in the air inlets generate a signature of staggered lines. e-tron badges adorn the fenders and the trunk lid; the diffuser conceals the exhaust system tailpipes.

All the strengths of the A6 model series*
Elegant design, a supremely spacious and cultivated interior, high ride comfort, comprehensively equipped and advanced infotainment - the Audi A6 L e-tron offers all of the strengths of the successful A6 model series. It will be produced by an Audi joint venture with FAW-Volkswagen in the northern Chinese city of Changchun, and will be launched on the Chinese market in 2016.

Fuel consumption of the models named above:

Audi A3 Sportback e-tron:
Combined fuel consumption in l/100 km: 1.7 – 1.5** (138.4 – 156.8 US mpg);
ombined power consumption in Wh/km: 124 – 114**;
Combined CO2 emissions in g/km: 39 – 35** (62.8 – 56.3 g/mi)

Audi A6:
Combined fuel consumption in l/100 km: 9.6 – 4.2** (24.5 – 56.0 US mpg);
Combined CO2 emissions in g/km: 224 – 109** (360.5 – 175.4 g/mi)

**The fuel consumption and the CO2 emissions of a vehicle vary due to the choice of wheels and tires. They not only depend on the efficient utilization of the fuel by the vehicle, but are also influenced by driving behavior and other non-technical factors.
