Performance & Powertrain Comparison

Performance is a major decision point for many SUV buyers. Here’s how the 2026 Acura MDX and 2026 Lexus RX compare under the hood.

2026 Acura MDX

• Engine: Standard 3.5-liter V6

• Horsepower: Approximately 290 hp

• Torque: Approximately 267 lb-ft

• Transmission: 10-speed automatic

• Drive Options: Front-wheel drive standard; Super Handling All-Wheel Drive™ (SH-AWD®) available

• Towing Capacity: Up to 5,000 lbs when properly equipped

The MDX’s V6 provides a blend of power and smooth acceleration for both city driving and highway cruising. With the available SH-AWD® system, the MDX offers enhanced traction and handling, helping drivers feel confident in a range of driving conditions.

2026 Lexus RX

• Engine Options:

  • Standard 2.4-liter turbocharged four-cyl.

  • Optional hybrid powertrain in some trims

• Horsepower: Ranges from ~275 hp (gas) to total system output of ~246–308 hp (hybrid, varies by model)

• Torque: Varies by engine choice

• Transmission: 8-speed automatic or Electronically Controlled Continuously Variable Transmission (ECVT) on hybrids

• Drive Options: FWD or All-Wheel Drive

• Towing Capacity: Up to ~3,500 lbs (depending on engine and configuration)

The RX’s available powertrains focus more on smooth, refined acceleration and fuel efficiency, particularly with the hybrid system. While the standard turbo four-cylinder delivers confident performance for typical driving scenarios, the MDX’s larger V6 gives it an edge in torque and towing capability.

Performance Takeaway:
If you prioritize a stronger V6 powertrain and higher towing capacity, the MDX is likely to be more satisfying. If your focus is on refined acceleration and hybrid efficiency, the RX’s options may appeal more.

Interior Comfort & Space

Passenger comfort and cargo space are critical factors, especially for families and long trips.

2026 Acura MDX Interior

• Three-row seating for up to 7 passengers as standard

• Generous legroom and headroom in the first and second rows

• Third row usable for adults on shorter trips and ideal for children

• Cargo space is strong behind third row and expands significantly with seats folded

• Materials include available premium leather, wood trim, and contrast stitching in higher trims

The MDX is designed with versatility in mind: third-row seating expands passenger capacity while maintaining respectable cargo space. The cabin’s design emphasizes driver engagement and ease of use.

2026 Lexus RX Interior

• Two-row seating for up to 5 passengers (standard RX)

• Optional RX L trims offer a third row, but space is tighter than in the MDX third row

• Refined materials and quiet cabin experience common across trims

• Strong emphasis on luxurious appointments and comfort

The RX interior is known for its refined ambiance and quiet ride, with high-quality materials throughout. However, the optional third row in RX L models is generally less spacious and more suitable for occasional passengers than the MDX’s third row.

Interior Takeaway:
The MDX offers more usable seating and cargo flexibility, especially for families or frequent long-distance travel. The RX emphasizes refined comfort and upscale materials, with less focus on maximum passenger volume.
