Engine Specifications
The Lexus IS 300 is powered by a 2.0-liter turbocharged inline-four engine that produces 260 horsepower and 277 lb-ft of torque. This engine is paired with an eight-speed automatic transmission.

According to reviews, the IS 350 can accelerate from 0 to 60 mph in around 5.7 seconds, while the IS 300 takes approximately 6.9 seconds to reach the same speed. The IS 350 also has a higher top speed, making it the more performance-oriented model of the two.
Fuel Economy
The smaller and more efficient engine in the IS 300 gives it an advantage in fuel economy. The IS 300 is rated at 24 mpg in the city and 32 mpg on the highway, while the IS 350 achieves 20 mpg in the city and 28 mpg on the highway.
For drivers seeking a balance of performance and efficiency, the IS 300 may be the more appealing choice, especially for daily commuting or city driving. The IS 350, on the other hand, is better suited for those who prioritize a more exhilarating driving experience.
