Why is the Audi A6 55 TFSI e quattro known as a plug-in hybrid vehicle?

I am looking to buy an Audi A6 and I noticed that there are different models with different names. One of them is the Audi A6 55 TFSI e quattro. What is the meaning of the '55 TFSI e' and 'quattro' in this model name?

The '55' in the model name indicates the engine size in liters. The 'TFSI' stands for 'Turbo Fuel Stratified Injection', which is Audi's term for their turbocharged direct injection gasoline engines. The 'e' refers to the car being a plug-in hybrid, while 'quattro' means the car has all-wheel drive.

The Audi A6 55 TFSI e quattro is a plug-in hybrid with a 2.0-liter TFSI engine and an electric motor, providing a combined output of 362 horsepower and 369 lb-ft of torque. The 'e' in the model name signifies the car's ability to run on electric power alone, providing a fuel-efficient and eco-friendly driving experience.

When you see 'quattro' in the name of an Audi vehicle, it means that it has all-wheel drive. The Audi A6 55 TFSI e quattro has a hybrid powertrain, with the '55' indicating its engine size and the 'TFSI' representing its turbocharged direct injection engine. The 'e' stands for the car's plug-in hybrid technology.
