Frequently Asked Questions

Common questions about comparing the 2025 Mercedes-Benz GLA-Class and 2026 Lexus RX.

Is the fuel economy difference between the GLA and the RX worth the price gap?

It certainly is a factor; the 2025 GLA achieves 29 MPG combined, while the 2026 RX manages 25 MPG combined. Over several years, this 4 MPG difference can offset some of the RX’s higher initial $49,725 MSRP, especially since both require premium fuel.

How much bigger is the Lexus RX in physical size compared to the Mercedes GLA?

The RX is substantially larger; it measures 192.5 inches in length and 75.6 inches in width, towering over the more compact GLA which is only 173.6 inches long and 72.2 inches wide. This size difference directly impacts interior and cargo room.

Do I need premium fuel for both of these luxury crossovers?

Yes, the 2025 Mercedes-Benz GLA-Class explicitly requires premium unleaded fuel. Conversely, the 2026 Lexus RX only lists premium unleaded as 'recommended,' suggesting it might operate adequately on lower grades, although performance gains are likely achieved with premium.

Which vehicle offers a better driving experience for spirited driving?

The 2026 Lexus RX is the performance leader here, offering 275 hp and 317 lb-ft of torque, giving it a clear advantage over the GLA's 221 hp and 258 lb-ft of torque.

If cargo capacity is key, how much more space do I get with the Lexus RX?

You gain significantly more storage with the RX; its 29.6 cu ft of cargo capacity nearly doubles the GLA’s 15.4 cu ft cargo volume, making the RX far more practical for larger items or family trips.

Does the difference in transmission type matter between these two FWD models?

Yes, the GLA uses an 8-speed automated manual, which can feel different during low-speed maneuvers, whereas the RX employs a more conventional 8-speed shiftable automatic, often preferred for smoother, predictable shifting.
