The Audi Q5 wins for buyers prioritizing value, fuel efficiency, and a sportier driving experience, starting at $45,400 with 26 mpg combined The Lexus RX 350 is the better choice for those who need more interior space, stronger base power (275 hp vs 201 hp), and legendary Toyota/Lexus reliability, though it starts higher at $51,550 Both earn NHTSA 5-star overall safety ratings
Why This Comparison Matters
This comparison crosses segment boundaries—the Q5 is a compact luxury SUV while the RX 350 is a midsize—making the decision less about direct competition and more about whether the extra size of the RX justifies its higher price
The Audi Q5 is Audi's best-selling model in America, representing the brand's expertise in building refined, tech-forward SUVs The Lexus RX has dominated the luxury midsize SUV market for decades, known for exceptional build quality and reliability
Buyers cross-shopping these vehicles typically value comfort, technology, and brand prestige. The choice often comes down to priorities: maximum space and long-term reliability (RX) versus driving dynamics and lower initial cost (Q5).

Design and Interior Quality
Exterior Styling
The 2025 Audi Q5 features a complete redesign with sharper lines, a larger Singleframe grille, and available LED matrix headlights The design is more aggressive than previous generations while maintaining Audi's signature understated elegance. Buyers can also opt for the Q5 Sportback variant with its sloped roofline for a coupe-like profile
The Lexus RX 350 presents a bolder, more dramatic appearance with its spindle grille and sharp body creases The current generation introduced a sportier stance compared to its predecessors. During a week with an RX 350 F Sport, the exterior styling drew more attention in parking lots than the more conservative Q5.
Interior and Cabin Space
The size difference becomes apparent inside. The RX 350 offers noticeably more passenger space, particularly in the rear seats where legroom is generous for adults The dashboard features a 14-inch touchscreen (12.3-inch on base models) with improved software responsiveness compared to earlier Lexus infotainment systems
The Q5's cabin feels more driver-focused and sporty, with a 12.3-inch digital instrument cluster and an available 10.1-inch or 12.3-inch central display Material quality is excellent in both, though the Q5's Virtual Cockpit Plus digital gauges give it a more modern, tech-forward appearance.

Interestingly, despite the RX's larger exterior, the Q5 offers more maximum cargo space with the rear seats folded This reflects the Q5's more efficient packaging—a consideration for buyers who frequently haul larger items.
Performance and Efficiency
Engine Options
2025 Audi Q5 Powertrains:
40 TFSI: 2.0L turbo-4, 201 hp, 236 lb-ft
45 TFSI: 2.0L turbo-4, 261 hp (select trims)
55 TFSI e PHEV: 362 hp combined, 23 miles electric range
SQ5: 3.0L turbo V6, 349 hp
2025 Lexus RX 350 Powertrains:
RX 350: 2.4L turbo-4, 275 hp, 317 lb-ft
RX 350h Hybrid: 2.5L hybrid, 246 hp combined
RX 450h+ PHEV: Plug-in hybrid, approximately 37 miles EV range
RX 500h F Sport Performance: 367 hp
The RX 350's base 275-hp engine significantly outperforms the Q5's standard 201-hp unit To match the RX's power, Q5 buyers must upgrade to higher trims or the SQ5, which substantially increases the price.
Driving Experience
The Q5 delivers a sportier, more engaging driving experience with precise steering and composed handling through corners The quattro all-wheel-drive system is standard and provides confident traction in varied conditions. During canyon road testing, the Q5 felt nimble and responsive—qualities that make daily driving more enjoyable.
The RX 350 prioritizes comfort over sportiness The ride is exceptionally smooth, absorbing road imperfections that the firmer Q5 transmits to occupants. For highway cruising and urban commuting, this approach reduces fatigue. The F Sport Handling trim adds adaptive suspension for buyers wanting more dynamic handling
