What motor does an Acura RDX have?

The Acura RDX is built around a turbocharged 2.0-liter inline-four engine. In the standard lineup it delivers about 272 horsepower and 280 lb-ft of torque with a 10-speed automatic transmission, and a high-performance Type S variant uses a tuned version of the same engine for greater output. This article breaks down the engine options and what they mean for everyday driving.

Core engine in the standard RDX

Below are the key specifications and features of the engine that powers the majority of RDX models. This helps clarify what most buyers get in daily use.

Key specifications for the standard RDX engine:



• Displacement and configuration: 2.0-liter inline-four (I-4) turbocharged


• Power output: 272 horsepower


• Torque: 280 lb-ft


• Transmission: 10-speed automatic


• Drivetrain: Front-wheel drive (FWD) standard; all-wheel drive (SH-AWD) available

Concluding: The standard RDX relies on a robust 2.0L turbo I-4 that balances power with efficiency, available with optional SH-AWD for extra traction.

RDX Type S: higher-performance variant

For buyers seeking more spirited performance, Acura offers the Type S variant that uses a higher-output version of the same 2.0-liter turbo engine. The Type S delivers significantly more horsepower and torque and comes with sport-oriented tuning and features.

Highlights of the Type S engine setup:



• Engine base: 2.0-liter turbocharged inline-four (same displacement, higher boost/tune)


• Power output: up to about 355 horsepower


• Torque: up to approximately 354 lb-ft


• Transmission: 10-speed automatic


• Drivetrain: SH-AWD standard

Concluding: The Type S represents Acura’s performance-focused iteration of the RDX, applying a tuned version of the base engine to deliver substantially more power while maintaining the model’s familiar dynamics.

Context and practical notes

Across the lineup, the RDX’s engine is paired with advanced chassis tech, including Acura’s Super Handling All-Wheel Drive (SH-AWD) on most trims and a responsive eight- or ten-speed transmission, depending on model year. There are no hybrid or plug-in variants currently offered in the standard RDX lineup; efficiency is improved through turbocharging and transmission design rather than electrification.

In sum, the Acura RDX’s motor is centered on a turbocharged 2.0-liter inline-four, with a more powerful Type S variant available for drivers who want extra performance from the same basic engine architecture.

Summary: The RDX is powered by a turbocharged 2.0L inline-four, 272 hp / 280 lb-ft in standard form, with the Type S bumping output to around 355 hp and 354 lb-ft. It uses a 10-speed automatic and SH-AWD is available, offering a balance of everyday usability and sportier performance.

Do Acuras have Honda engines?

Yes, Acuras have Honda engines, as Acura is a luxury division of Honda and many of the engines share a common architecture. While they use the same core engines, Acura engines are often tuned for higher performance. For example, the turbocharged 1.5L 4-cylinder engine in the 2023 Acura Integra is the same as the one found in the contemporary Honda Civic Si, though it has an Acura badge and is designed for premium fuel. 

• Shared architecture: Acura and Honda vehicles often share the same core engine designs. 
• Performance tuning: Acura engines may be tuned differently to provide higher performance. 
• Performance focus: Acura's performance models, like the Type S, use specialized versions of Honda engines. 
• Examples:
  • The 2023 Acura Integra uses the same turbocharged 1.5L 4-cylinder engine as the Honda Civic Si. 
  • The 3.5-liter V6 in the Acura MDX is similar to the one used in the Honda Pilot and Ridgeline.
