Specs at a Glance


In the Lexus fleet, shoppers enjoy a wide selection of styles. With overlapping pricing schemes, the 2018 Lexus IS300 and Lexus ES350 compete with one another for your attention. This comparison helps illuminate what each car can do for you.

These two models provide serious performance to please the daily commuter and the pleasure cruiser. A Lexus IS300 driver commands an inter-cooled turbo I-4. Power outlay is 241 horsepower and 258 lb-ft of torque. An eight-speed automatic transmission and rear-wheel drive are standard. Fuel economy is a healthy 32 mpg highway. The shorter IS model carves three inches off of the Lexus ES350 turning diameter, making it more maneuverable in tight spaces.

Despite its large size, the Lexus ES350 weighs the same or less than the Lexus IS300. This helps it do more with its V6 power. Paired with a six-speed automatic and front-wheel drive, this engine earns 30 mpg highway. Yet it produces 268 horsepower and 248 lb-ft. of torque.


Lexus ES350 curb appeal comes from the L-finesse inspired the sleek look of its cabin. A one-piece spindle grille marks the front while semi-integrated dual-exhaust pipes mark the rear. Its 17-inch alloy wheels wear a split ten-spoke design. Racing right behind, the smaller IS300 enjoys its own curb appeal. Aerodynamic touches include the color-coordinated front air dam. A moonroof helps open up the cabin. IS300 models offer NuLuxe upholstery in shades of flaxen, black, Chateau and F Sport Rioja Red. The ES300 adds even more colors such as stratus gray and noble brown. In fact, the ES350 has many different accents including piano black, matte honey bamboo, and linear dark mocha wood.

As you would expect, the Lexus ES350 sedan is taller, wider and longer than the Lexus IS300. Passenger volume is 100.1 cu.ft. vs. 90 cu.ft. in the IS300. As a midsize sedan, the RS 350 offers a bigger backseat with a remarkable 40 inches of rear legroom. However, Lexus actually gives you slightly more front-row headroom and legroom in the IS 300, which is more driver-focused than passenger-focused. The ES350 is definitely the one you want for long-distance travel if you have lots of luggage. Its large trunk measures 15.2 cu.ft.


With the Lexus IS300, seats are 10-way power-adjustable. A 7-inch display screen brings you HD radio, Bluetooth 3.0 streaming audio, and SiriusXM capability. Scout GPS Link provides navigation. These are ES350 standards as well, except that it has an eight-inch touchscreen. You can divide the screen into three sections to control audio, HVAC and optional navigation functions. Lexus cache radio lets you rewind up to ten minutes of your FM or HD radio station. ES350 models also offer a power rear sunshade, a one-touch power trunk, and a panoramic roof.

On both, the pre-collision system includes a forward collision warning, an emergency auto brake, and pedestrian detection. High-Speed Dynamic Radar Cruise Control regulates your speed according to traffic flow. A lane departure alert includes a steering assist to keep you within the lane lines. Intuitive parking assist is offered along with a blind-spot monitor and rear cross-traffic alert.

Both cars have ten airbags, energy-managing crumple zones, and side-impact door beams. In addition, shoppers enjoy ten years of complimentary Lexus Enform Safety Connect. This includes an SOS button and Automatic Collision Notification.
