The main difference between the A4 45 TFSI and A4 40 TFSI models is the engine size and power output. The A4 45 TFSI has a 2.0-liter I4 engine with 248 horsepower, while the A4 40 TFSI has a 2.0-liter I4 engine with 201 horsepower. This means the A4 45 TFSI will have more acceleration and power, but the A4 40 TFSI will likely have better fuel efficiency.

Another important difference is in the standard features. The A4 45 TFSI comes with features such as leather upholstery, heated front seats, and a sunroof, while the A4 40 TFSI does not. Depending on your priorities, this may sway your decision.
