Does the Acura RDX or MDX Have More Horsepower?

The 2026 Acura MDX offers more muscle under the hood than the RDX. While the standard 3.5-liter V6 produces respectable output, the available 3.0-liter turbo V6 engine elevates performance to an impressive 355 horsepower and 354 pound-feet of torque.

The 2026 Acura RDX, for sale in Erie, takes a different approach with its 2.0-liter turbocharged 4-cylinder engine that delivers 272 horsepower and 280 pound-feet of torque. This powertrain provides excellent responsiveness for daily commuting and weekend adventures throughout the region.

For drivers who need serious hauling capability, the MDX towing capacity of5,000 pounds is perfect. This makes the new Acura MDX ideal for boat launches at Presque Isle State Park or hauling recreational equipment to Pennsylvania's mountain regions. If you occasionally tow smaller items, the 1,500-pound towing capacity of the RDX is more than enough.

Does the RDX or MDX Offer Better Fuel Efficiency?

Northwestern Pennsylvania Acura drivers who prioritize fuel economy will appreciate the superior 2026 RDX mpg ratings. This compact luxury SUV achieves up to 27 highway mpg, making it an excellent choice for frequent commutes between Erie and surrounding communities.

The MDX fuel economy numbers are slightly lower though still comparable, especially considering its larger size and optional high-performance engine. The difference represents meaningful savings over time, particularly for drivers covering significant daily mileage.

Which Is Bigger, the MDX or RDX?

Although family size often determines the winner in this comparison, the MDX is larger than the RDX. The 3-row MDX configuration accommodates up to seven passengers, making it perfect for larger families or those who frequently transport groups around the Erie area.

The 2026 RDX maximizes comfort for up to five occupants with generous front legroom of 42.0 inches -- actually exceeding the MDX model's legroom thanks to its 2-row layout. This extra space translates to enhanced comfort during longer drives to Erie or Pittsburgh.

Cargo capacity tells an interesting story between these models. The RDX offers 79.8 cubic feetof maximum storage space, while the maximum MDX cargo capacity reaches an impressive 95.0 cubic feet when properly configured. Behind the second row, the MDX still delivers substantial storage for daily needs.
