2026 Lexus RX 350 vs. 2026 BMW X5: Which Luxury SUV Wins for Temecula Shoppers?
Shoppers cross-shopping the midsize luxury SUV segment in Temecula and across the Inland Empire keep landing on two names: the 2026 Lexus RX 350 and the 2026 BMW X5. Both seat five and both deliver a genuinely premium cabin, but they are built around different priorities — the RX 350 around comfort, value, and long-term ownership, the X5 around power and driving dynamics. Here is an honest, spec-by-spec look at where each one earns its price.
At a Glance: 2026 RX 350 vs. X5

Pricing & Value
The clearest difference between these two is price. The RX 350 starts at an MSRP of $51,175, while the X5 opens at an MSRP of $69,750 – roughly $18,600 more before you add a single option.
| Lineup | 2026 Lexus RX 350 | 2026 BMW X5 |
|---|---|---|
| Trims | 6 (Standard, Premium, Premium+, F SPORT Design, Luxury, F SPORT Handling) | 4 (sDrive40i, xDrive40i, xDrive50e, M60i) |
| Price range | $51,175 – ~$63,500 | $69,750 – $95,050 |
| Powertrains | 2.4L turbocharged gas (FWD/AWD) | Turbo inline-6 gas; xDrive50e plug-in hybrid; M60i twin-turbo V8 |
A loaded RX 350 Luxury AWD approaches an MSRP of $63,500 — still below where the upper half of the X5 lineup begins. The X5 climbs to an MSRP of $95,050 for the V8 M60i, and BMW’s optional packages add up quickly.
Manufacturer’s Suggested Retail Price (MSRP) for new vehicles includes manufacturer and distributor options and delivery, process and handling fees, which may be subject to change at any time. MSRP excludes taxes, title, license and dealer installed options, accessories, fees and charges. MSRP is not the dealer advertised price. Dealer price will vary. The dealer sets the final price.
Performance & Efficiency
The X5 is the more powerful SUV. Its base turbocharged inline-six (with 48-volt mild-hybrid assist) makes 375 horsepower and 398 lb-ft, and the lineup climbs to a 523-horsepower twin-turbo V8 in the M60i. The RX 350’s 2.4L turbocharged four produces 275 horsepower and 317 lb-ft — less outright muscle, but tuned for smooth, quiet, low-effort daily driving.
On EPA-Estimated economy, the two base gas models are nearly identical, both rated at 25 mpg combined.
| EPA-Estimated MPG | City | Highway | Combined |
|---|---|---|---|
| Lexus RX 350 (FWD) | 22 | 29 | 25 |
| Lexus RX 350 (AWD) | 21 | 28 | 24 |
| BMW X5 40i (RWD or AWD) | 23 | 27 | 25 |
Buyers who want electrified efficiency have paths in both camps — the Lexus RX family offers hybrid and plug-in-hybrid variants, and BMW offers the X5 xDrive50e plug-in hybrid.
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
Space & Comfort
On outright capacity, the X5 has the edge: 33.9 cubic feet behind the second row and up to 72.3 cubic feet with the seats folded, versus 29.6 and 46.2 cubic feet in the RX 350. What the RX prioritizes instead is ride comfort — a quiet, cushioned cabin engineered to isolate passengers — where the X5 leans firmer and more sport-tuned. Both seat five in these configurations.
Technology
The X5 makes the bigger visual statement inside, pairing a 12.3-inch digital instrument cluster with a 14.9-inch curved touchscreen running BMW Operating System 8.5. The RX 350 counters with a cleaner, more straightforward interface and standard wireless Apple CarPlay and Android Auto across every trim. If you value screen real estate and configurability, the X5 leads; if you value controls you can operate without a learning curve, the RX is easier to live with day to day.
Safety
Both SUVs arrive well-equipped. Every RX 350 includes Lexus Safety System+ 3.0 as standard — pre-collision braking with pedestrian detection, adaptive cruise control, lane-tracing assist, blind-spot monitoring, and rear cross-traffic alert. The X5 comes standard with Active Driving Assistant (forward collision mitigation, lane departure warning, and blind-spot detection); BMW’s most advanced hands-free Highway Assistant — which operates up to 85 mph on compatible controlled-access highways — is an available upgrade rather than standard equipment.
Driver-assistance and active safety systems are supplemental and do not replace attentive driving. These systems have limitations and may not operate in all conditions. Always drive attentively, obey traffic laws, and consult the manufacturer’s materials for system details and limitations.
Warranty & Ownership
Lexus backs the RX 350 with a 4-year/50,000-mile basic warranty and a 6-year/70,000-mile powertrain warranty, alongside the brand’s well-documented reputation for reliability and strong resale value. BMW covers the X5 with a 4-year/50,000-mile basic warranty and a matching 4-year/50,000-mile powertrain warranty, plus 3 years/36,000 miles of complimentary scheduled maintenance. For shoppers weighing total cost of ownership over the years they plan to keep the vehicle, the RX 350’s longer powertrain coverage and resale track record remain meaningful advantages.

The Verdict
Both are excellent midsize luxury SUVs, and the right answer comes down to what you value. Choose the BMW X5 if outright power, maximum cargo room, larger screens, and available V8 or plug-in-hybrid performance justify a starting price nearly $18,600 higher. For most shoppers in Temecula and the Inland Empire — those who prioritize value, a serene ride, a comprehensive standard safety suite, and lower long-term ownership costs — the 2026 Lexus RX 350 is the smarter buy, and it is the one you can see and drive at Temecula Valley Lexus.
