How fast is the Acura RLX Sport Hybrid?
The Acura RLX Sport Hybrid SH-AWD delivers a combined power output of about 377 horsepower, with 0-60 mph times in the mid‑5-second range and a governed top speed around 130 mph. In practice, it offers brisk acceleration for a luxury sedan while prioritizing smoothness and efficiency.
Performance numbers
Here are the core figures that define the RLX Sport Hybrid’s speed and power. Values are representative of the model years when the hybrid was offered and can vary slightly by year and configuration.
- Combined system horsepower: 377 hp (about 281 kW)
- Combined torque: roughly 341 lb-ft (462 Nm)
- Drivetrain: Sport Hybrid SH-AWD with a 7-speed dual-clutch automatic and a three-motor hybrid system
- 0-60 mph: approximately 5.5 to 5.8 seconds
- Top speed: electronically limited to about 130 mph
- Transmission: 7-speed dual-clutch automatic
- EPA fuel economy (real-world varies): around 28–30 mpg combined
Taken together, these numbers place the RLX Sport Hybrid in the upper tier of mid-size luxury sedans for acceleration, while delivering efficiency that was uncommon in its class at the time of its release.
How the three-motor hybrid arrangement works
To explain the speed, it helps to understand the hybrid architecture. The RLX Sport Hybrid SH-AWD uses three electric motors partnered with a 3.5-liter V6 and a seven-speed dual-clutch automatic. Two electric motors are integrated with the front axle and the transmission to assist the front wheels, while a third motor powers the rear axle to enable all-wheel drive. This setup enables rapid torque delivery, smoother throttle response, and the ability to run on electric power at low speeds when the battery is charged.
In practice, the system blends gas and electric power for seamless acceleration. The motors can provide torque fill when the gasoline engine is under load, helping the car reach 60 mph more quickly than a conventional V6 with a similar curb weight. It also enables smoother shifts and enhanced stability during rapid acceleration or lane changes.
- The front axle uses two electric motors in conjunction with the 7-speed dual-clutch automatic to deliver drive power to the front wheels.
- A third electric motor directly powers the rear axle, enabling SH-AWD for improved traction and cornering feel.
- The seven-speed dual-clutch transmission coordinates between gasoline and electric propulsion to optimize response and efficiency.
- The system can operate in modes that favor electric-only propulsion at low speeds when battery state of charge allows, enhancing quietness and efficiency.
These elements work together to deliver strong mid-range acceleration, confident highway merging, and a refined overall driving experience that emphasizes smooth, linear power rather than sheer loudness.
Real-world considerations and comparisons
While official numbers set the benchmark, real-world speed can vary based on battery charge, ambient temperature, vehicle payload, and road conditions. The RLX Sport Hybrid’s strength lies in its balanced performance: quick bursts when needed, plus steady, comfortable long-distance cruising with good fuel efficiency for its class.
Summary
The Acura RLX Sport Hybrid SH-AWD combines 377 horsepower with a sophisticated three-motor hybrid system to deliver brisk acceleration, a roughly 130 mph top speed, and efficiency that stands out in its era. In practice, drivers can expect 0-60 mph times in the mid‑5 seconds, with smooth power delivery and stable, confident handling thanks to SH-AWD. While not a sport-only performance sedan, it offers a compelling mix of speed, refinement, and efficiency for a luxury hybrid sedan.
