Naturally Aspirated V6 Delivers Smooth Power

Every 2026 Lexus IS 350 is powered by a naturally aspirated 3.5-liter V6 engine featuring an aluminum block and cylinder heads, dual overhead cams, 24 valves, dual Variable Valve Timing with intelligence (VVT-i), and D-4S electronic fuel injection.

Rear-Wheel Drive or All-Wheel Drive

The Lexus IS lets drivers choose the drivetrain that best matches their driving style.

Rear-Wheel Drive

Rear-wheel drive delivers the classic sports sedan feel by sending power to the rear wheels. It also pairs with an eight-speed automatic transmission featuring paddle shifters for quicker gear changes and a more engaging drive.

Fuel Efficiency Supports Everyday Driving

These modes modify throttle response, transmission behavior, steering feel, and, when equipped, suspension settings to better match different road conditions and driving styles.

Adaptive Variable Suspension Improves Handling

The system helps provide:

• Better body control through curves

By automatically adapting to changing road conditions, the suspension creates a balanced blend of comfort and performance.

This performance component helps:

• Distribute power between the rear wheels
