What are the different types of Audi A1 engines and what are their specifications?

I am currently in the market for an Audi A1 and I am interested in understanding the variety of engines available for this model. Can someone provide a breakdown of the different types and their respective specifications?

The Audi A1 comes with three different engine options - the 1.0 TFSI, 1.5 TFSI, and 2.0 TDI. The 1.0 TFSI is a three-cylinder engine with 94 horsepower and 118 lb-ft of torque. The 1.5 TFSI is a four-cylinder engine with 147 horsepower and 184 lb-ft of torque. The 2.0 TDI is a four-cylinder diesel engine with 114 horsepower and 236 lb-ft of torque.

In terms of fuel economy, the 1.0 TFSI has an estimated EPA rating of 34 mpg combined, the 1.5 TFSI has a rating of 33 mpg combined, and the 2.0 TDI has a rating of 44 mpg combined. Overall, the 1.5 TFSI offers the best balance of power and efficiency.
