Audi has revealed the third plug-in hybrid in its lineup, the 2021 A7 55 TFSI e, a powerful option for executive car buyers. It joins the Audi Q5 TFSI e and Audi A8 TFSI e as the only PHEVs in the company's U.S. lineup.

The A7 gets its power from a turbocharged 2.0-liter four-cylinder engine that is paired with an electric motor and seven-speed dual-clutch transmission. The car has a total system output of 362 horsepower and 369 pound-feet of torque. All-wheel drive is standard.

Audi's new sedan can run as a hybrid or on all-electric power. Drivers can utilize the vehicle in three drive modes: hybrid, EV, and Battery Hold. Hybrid mode is activated automatically when the navigation system is issuing guidance in order to optimize battery power and reduce fuel consumption. In EV mode, the car exclusively uses battery power up to a certain speed. Battery Hold mode utilizes the car's powertrain to keep the battery capacity at its current level.

The A7 holds its lithium-ion battery under the rear cargo area of the sportback sedan. Final EPA-estimated fuel economy and range numbers are pending. The 14.1-kilowatt-hour battery features 104 pouch cells with a voltage of 381 volts.

Audi's predictive efficiency assist technology adjust the vehicle's behavior to save on fuel. According to the automaker, ". Detectable haptic feedback from the accelerator pedal and a visual signal in the MMI and head-up display indicate the proper time to let off the accelerator to use as much kinetic energy as possible."

The model comes standard with Audi's S line exterior package, which includes specific front and rear fascia designs, fender badgers, and illuminated doorsill inlays. The car also has Matrix-design LED headlights, high beam assist, quad-zone automatic climate control, Audi advanced key, Audi Virtual Cockpit, ad PHEV-specific displays within the infotainment system and cockpit. It rides on 20-inch Audi Sport five-twin-arm wheels wrapped in all-season tires.

The roster of standard features continues with audible low-speed exterior e Sound, a top view camera with Virtual 360 view, Integrated Toll Module, the Audi MIB 3 infotainment operating system, heated front seats, and leather upholstery for all five passengers.

A variety of packages are available.

Audi Virtual Cockpit now displays speed reductions, including those for speed limits, tow signs, curves, downward slopes, traffic circles, intersections, and highway exits.

The fresh version of the A7 can be charged at any SAE J1772 charging station or at home. Audi has partnered with Amazon Home for home charger installation should a vehicle buyer decide they want to install a charger at their residence. Charging can be monitored via the myAudi app.

The 2021 Audi A7 TFSI e starts at $74,900, a $5,000 increase over the base gasoline-only A7 55 TSFI. It will be available in Premium Plus and Prestige trim levels (the traditional A7 55 is available in three, including the lower grade Premium offering).

Audi says that customers who purchase purchasing the 2021 Audi A7 55 TFSI e will be eligible for a federal tax credit of up to $6,712. Additional state incentives may also be available.

The model is expected to arrive in dealerships later this year.
