A plug-in hybrid Audi A6 55 TFSI e quattro has given start to the large-scale electrification of the German brand’s models. The new sedan got a 367 hp powertrain. The price is almost 70,000 euros.
Eco-friendliness does not get in the way of performance
With no lack of dynamics, designers could provide good eco-friendliness. In particular, CO2 emissions do not exceed 47 g/km.
The hybrid powertrain comprises a 252-hp 4-cylinder 2.0 TFSI gasoline engine and a 105-kW electric motor. The total power output is 367 hp. The top torque of 369 lb-ft (500 Nm) is already available at 1250 rpm. Power is transmitted to all four wheels through a S tronic seven-speed automatic gearbox.
A 14.1-kWh lithium-ion battery is located under the cargo compartment and doesn’t steal space.
The A6 TFSI e 55 quattro can boast the dynamics of a performance car. It takes 5.6 seconds to accelerate from 0 to 62 mph (100 km/h). The top speed is limited to 155 mph (250 km/h), an electric-only range is up to 84 mph (135 km/h).
According to WLTP tests, the hybrid A6’s driving range is 33 miles (53 km). The automaker claims the new car is the only premium all-wheel drive hybrid sedan.
Here we can argue. The Lexus LS 500h also has an all-wheel drive, but it is not plug-in one. It has a 354-hp powertrain with a six-cylinder engine, not a four-cylinder one.
Mode choices: from gasoline to electricity
The Audi A6 55 TFSI e quattro works in three modes: purely electric, hybrid and normal, when electric energy is used only from time to time.
The last mentioned option is well for a long trip on the highway. All advantages of the electric drive are leveled in this case.
The hybrid mode is good for city. Sometimes it goes into the pure electric mode, when the internal combustion engine is used only as a generator to recharge the battery.
There is a travel planner among electronic assistants. The system forsees and counts a mode based on navigation data, online traffic, driving style, information from the camera and radar.
The electronic assistant automatically makes a decision about free driving with a gas engine turned off, and also about its activation if necessary.
That is why the claimed fuel consumption of 112.0 – 123.8 mpg (2.1-1.9 l/100 km) does not seem unrealistic, although in real road conditions the vehicle’s engine will likely consume more fuel.
The plug-in hybrid sedan is already available to order, in Germany, at least, where the ‘green’ A6 is priced from 68,850 euros.
