Acura RSX Electric Powertrain

The arrival of the 2026 Acura RSX marks a historic shift for the brand. While the ZDX introduced Acura to the world of electrification, the RSX is the first model engineered from the ground up on the brand's own Honda-developed EV platform. This is a Software-Defined Vehicle designed to combine the heritage of the RSX nameplate with the limitless potential of electric torque.

For drivers in Indianapolis and the surrounding Hamilton County area, the RSX represents a move toward bespoke performance. Built right here in Ohio at the Honda EV Hub, this powertrain is tuned specifically for the agility and precision that Ed Martin Acura customers expect.

2026 In-House EV Platform (The Ohio Heritage)

1. 2026 In-House EV Platform (The Ohio Heritage)

Unlike previous electric efforts, the RSX is built on a proprietary architecture designed by Honda and Acura engineers. By moving away from shared platforms, Acura has been able to optimize the battery placement and motor calibration to prioritize a low center of gravity and a nearly 50/50 weight distribution.

  • Production: Handled at the Honda EV Hub in Marysville, Ohio, the same facility that produced the legendary NSX.
  • The Drive: Because the platform was designed "electric-first," there are no compromises for a traditional engine bay. This allows for a wider track and a "cab-forward" design that improves both interior space and high-speed stability on I-69.
  • Range: While final EPA figures are pending for late 2026, the in-house platform is engineered to target a competitive range exceeding 300 miles, with advanced thermal management for consistent performance in Indiana winters.

2. Dual-Motor Performance & Handling

The RSX comes standard with a high-performance Dual-Motor All-Wheel Drive setup. This configuration doesn't just provide traction; it uses independent motor control to provide active torque vectoring, mimicking the "Super Handling" characteristics of Acura’s famous mechanical systems.

  • Precision Engineering: The RSX features a sport-tuned double wishbone front suspension, a configuration typically reserved for high-end sports cars. This ensures that the front tires maintain a flat contact patch during aggressive cornering in Carmel or Noblesville.
  • Brembo® Braking: To manage the instant acceleration, the RSX is equipped with large Brembo® front brakes with signature red calipers, ensuring fade-free stopping power during spirited drives.
  • Acceleration: Early performance testing indicates a 0–60 mph time in the 4-second range, placing it firmly in the company of dedicated sport sedans.

ASIMO OS: The Brain of the RSX

The most significant technological leap in the RSX is the debut of the ASIMO Operating System (ASIMO OS). This is a proprietary, in-house software platform that acts as the "brain" of the vehicle.

  • Predictive Learning: ASIMO OS uses machine learning to adapt to your driving habits. If you typically take a certain route through Fishers at a specific time, the system can pre-condition the battery for maximum efficiency or adjust the climate control before you even enter the vehicle.
  • Software-Defined Performance: Unlike gas cars, the RSX can receive over-the-air (OTA) updates that physically change the driving dynamics. Acura can send updates that improve motor response, refine the suspension dampening, or even unlock new drive modes long after you’ve driven off the lot.

Maintenance Pro-Tips for RSX Owners

As a software-first vehicle, the RSX requires a different approach to maintenance than a traditional Acura. Here is how to keep your performance EV in peak condition:

  • Bi-Directional Charging Utility: The RSX features Mobile Energy Storage capabilities. This means you can use your RSX to provide home back-up power during an outage or power high-draw appliances at a tailgate near Lucas Oil Stadium. Ensure your home charger is compatible with bi-directional transfer.
  • OTA Update Readiness: Because the ASIMO OS is constantly evolving, we recommend keeping your vehicle connected to a stable Wi-Fi network at home. This ensures that safety and performance updates are downloaded and ready for installation without interrupting your schedule.
  • Brembo Care: High-performance Brembo® brakes are designed for heavy use but can develop "brake squeal" if they aren't bedded-in properly or if dust builds up. Our service team recommends a visual inspection of the calipers every 10,000 miles to ensure the specialized performance pads are wearing evenly.
