Cars like the 2019 Lexus IS 300 and 2019 Mercedes-Benz CLA are known for their outstanding performance. They come with powerful engines and deliver smooth and nimble handling. Nonetheless, the Lexus may fare better than the Mercedes-Benz in the performance department because of these reasons:

  • More powerful engine: The Lexus IS 300 is equipped with a 2.0-liter turbo-four that generates 241 horsepower, while the Mercedes-Benz CLA's standard 2.0-liter turbo-four makes only 208 horsepower.
  • Eight-speed transmission: The IS 300 features an eight-speed automatic transmission that contributes to faster acceleration and highway fuel efficiency. The CLA, on the other hand, uses a seven-speed automatic.
  • Tighter turning diameter: The Lexus may be easier to maneuver in tight spaces because its 34.2-inch turning diameter is 1.9 inches smaller than that of the Mercedes-Benz. As such, it may be a better car for urban driving.


As a compact car, the 2019 Lexus IS 300 has certain advantages over the sub-compact 2019 Mercedes-Benz CLA, such as:

  • Longer wheelbase: The wheelbase of the Lexus IS 300 measures 110.2 inches, which is 3.9 inches longer than the Mercedes-Benz CLA's. As a result, it may deliver a smoother ride and more composed handling.
  • Larger wheels: The IS 300 rides on 18-inch wheels, while the CLA comes standard with 17-inch wheels. The larger wheels help improve the Lexus' handling, ride quality, and brake cooling.
  • Heavier body: Weighing 3,583 pounds, the Lexus IS 300 is 309 pounds heavier than the Mercedes-Benz CLA. Its heavier body makes it feel more stable over uneven surfaces and around corners.
  • More legroom: The IS 300 may provide a more comfortable and relaxing ride on long journeys because of its more generous legroom. It offers 4.6 inches more legroom in the front row and 5.1 inches more legroom in the second row than the CLA.

Safety and Security

Cars from brands like Lexus and Mercedes-Benz routinely receive high safety ratings from the National Highway Traffic Safety Administration. While both the 2019 Lexus IS 300 and 2019 Mercedes-Benz CLA offer many advanced safety features, it looks like the 2019 Lexus IS 300 will take the cake in this department.

  • More standard driver-assistance technologies: The Lexus IS 300 offers automatic high beams, pedestrian detection, adaptive cruise control, and lane-keeping assistance as standard safety equipment. These driver-assistance technologies are either unavailable or optional in the Mercedes-Benz CLA.


The 2019 Lexus IS 300 is slightly more expensive than the 2019 Mercedes-Benz CLA, but its advantages in performance, comfort, and safety more than make up for the extra cost. If you want to know if the Lexus IS 300 can meet your expectations, feel free to arrange a test drive.
