Drivetrain
The Audi A5 uses a 4-cylinder petrol with direct fuel injection, turbocharging producing 150kW and 340Nm of torque, sent through a 7-speed s tronic to a FWD layout. It covers the 0-100km/h sprint in 7.8 seconds.
The BMW 5 Series responds with a Petrol making 150kW and 300Nm, paired to a auto driving the rear wheels. It gets to 100km/h in 5.6 seconds.
Power output is identical on paper, so the difference comes down to tuning, weight distribution, and suspension. In the real-world sprint, the BMW 5 Series is 2.2s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
