2 Answers
The differences between the low-power version and high-power version of the Audi A4L are: different maximum power, different maximum torque, and different driving methods. The specific differences between the two are as follows: Different maximum power: A4L low-power version: maximum power (kW/rpm) 140/4200-6000. A4L high-power version: maximum power (kW/rpm) 185/5000-6000. Different maximum torque: A4L low-power version: maximum torque (Nm/rpm) 320/1450-4200. A4L high-power version: maximum torque (Nm/rpm) 370/1600-4500.
The high and low power engines of the Audi A4L primarily share the same base engine but differ in tuning. The low-power version, such as the 35 TFSI, delivers around 150 horsepower, offering smooth and fuel-efficient daily driving, especially suitable for urban commuting. Acceleration is responsive but lacks strong push-back sensation. The high-power version, like the 45 TFSI, boasts approximately 250 horsepower, with more aggressive turbocharging and quicker response, making high-speed overtaking exceptionally sharp. Hardware-wise, the high-power variant features reinforced crankshafts and pistons to withstand greater pressure, coupled with more aggressive software tuning, enabling higher power output. The driving experience differs noticeably: the low-power version suits steady driving, while the high-power version delivers thrilling performance for speed enthusiasts, albeit with higher fuel consumption and a recommendation for 95-octane fuel. In terms of noise control, the high-power engine is louder during rapid acceleration, whereas the low-power version offers better quietness, impacting comfort. The choice depends on your craving for power.
