2026 Lexus IS 350 Trims and Features at Temecula Valley Lexus
The 2026 Lexus IS 350 arrives with a significantly streamlined lineup that focuses entirely on V6 performance. Lexus has discontinued both the four-cylinder IS 300 and the V8-powered IS 500 for the new model year, leaving the 3.5-liter V6 as the sole powertrain across the range. The result is a focused two-grade structure — the IS 350 F SPORT Design and the IS 350 F SPORT — with each grade available in rear-wheel drive or all-wheel drive.
This simplification removes the guesswork for Temecula and Murrieta shoppers who previously had to navigate multiple engine configurations. Every 2026 IS 350 now delivers 311 horsepower and 280 lb-ft of torque from the same naturally aspirated V6, so the buying decision comes down to two choices: which grade and which drivetrain.
F SPORT Design vs. F SPORT: Choosing Your Grade
Both grades share the IS 350’s athletic exterior with F SPORT styling — unique front and rear bumpers, a signature grille treatment, and 19-inch alloy wheels. Where they diverge is in the performance hardware and interior appointments.
The F SPORT Design serves as the entry point, pairing aggressive F SPORT aesthetics with comfort-oriented daily-driver features. The cabin is trimmed in NuLuxe synthetic leather with heated front seats, and the focus is on the visual and technology elements of the F SPORT identity.
The full F SPORT grade builds on that foundation with functional performance upgrades: bolstered, heated, and ventilated front sport seats; an F SPORT power-adjustable heated steering wheel; aluminum sport pedals; and satin interior trim accents. For drivers who want adjustable handling, the available F Sport Handling Package adds Adaptive Variable Suspension, a Torsen limited-slip rear differential (RWD models only), and additional Sport driving modes.

Performance and Drivetrain Options
The 3.5-liter naturally aspirated V6 produces 311 horsepower at 6,600 rpm and 280 lb-ft of torque at 4,800 rpm. Unlike many competitors that rely on smaller turbocharged four-cylinder engines, the IS 350’s larger-displacement V6 delivers power in a linear, progressive curve without turbo lag — a characteristic that Lexus has refined over years of V6 development.
The drivetrain choice affects more than just traction. Rear-wheel-drive models pair the V6 with an 8-speed Sport Direct-Shift automatic transmission optimized for quick, responsive shifts. All-wheel-drive models use a 6-speed automatic paired with a rear-biased AWD system that can shift power between axles to maintain traction. Both configurations are available on both grades.
Drivetrain Comparison
| Specification | Rear-Wheel Drive (RWD) | All-Wheel Drive (AWD) |
|---|---|---|
| Transmission | 8-speed Sport Direct-Shift automatic | 6-speed automatic |
| EPA-Estimated Fuel Economy | An estimated 19 city / 27 hwy / 22 combined MPG | An estimated 19 city / 26 hwy / 22 combined MPG |
| MSRP Premium vs. RWD | — | +$2,000 |
| Available on F SPORT Design | Yes | Yes |
| Available on F SPORT | Yes | Yes |
All figures shown are EPA estimated miles per gallon. Actual mileage will vary based on driving conditions, vehicle condition, and other factors.
For Corona commuters along the 91 corridor or Lake Elsinore drivers who value the additional confidence of all-weather grip, AWD is a practical upgrade. Drivers who prioritize the more direct sport sedan feel and additional gear ratios of the 8-speed may prefer RWD.
2026 Lexus IS 350 Pricing
| Configuration | Starting MSRP* |
|---|---|
| IS 350 F SPORT Design RWD | $46,795 |
| IS 350 F SPORT Design AWD | $48,795 |
| IS 350 F SPORT RWD | $49,245 |

The $2,450 step from F SPORT Design to F SPORT buys the performance seat package (heated and ventilated sport seats, heated steering wheel, aluminum pedals), satin trim, and access to the optional Handling and Technology packages. Both grades share the same engine, safety suite, and technology interface.
*MSRP for new vehicles covers manufacturer/distributor equipment and logistics fees, all of which are subject to revision. It does not account for taxes, registration, dealer-installed additions, or other local charges. MSRP is not a retail advertisement; actual dealer pricing will vary. The dealer sets the final price.
Technology and Cabin Features
The 2026 IS 350 interior receives its most significant update for this generation. A standard 12.3-inch Lexus Interface touchscreen replaces the previous 8-inch display, featuring built-in navigation, Wireless Apple CarPlay, Wireless Android Auto, and four USB-C ports. Directly ahead of the driver, a new 12.3-inch fully digital instrument cluster delivers crisp graphics with customizable display layouts that shift with the selected drive mode.
Audio comes standard as a 10-speaker Lexus Premium Sound system with a wireless charging pad. Audiophiles can upgrade to the optional 17-speaker Mark Levinson premium surround sound system, which is specifically tuned to the IS cabin acoustics and included as standard equipment on the Special Appearance Package.
The IS 350 is a five-passenger sedan with a driver-focused cockpit. Rear legroom measures 32.2 inches — comfortable for shorter trips or children, though taller adults may find extended rides snug. Cargo capacity is 10.8 cubic feet with 60/40-split folding rear seats that accommodate longer items when needed. Fallbrook and Vista shoppers who need more passenger volume may want to compare the Lexus IS and ES, which offers a larger cabin in the same luxury sedan segment.
Standard Safety: Lexus Safety System+ 3.0
Every 2026 IS 350 comes equipped with Lexus Safety System+ 3.0 at no additional cost. The suite includes:
- Pre-Collision System (PCS) with Pedestrian Detection
- Full-Speed Dynamic Radar Cruise Control
- Lane Tracing Assist
- Lane Departure Alert with Steering Assist
- Automatic High Beams
- Road Sign Assist
- Blind Spot Monitor with Rear Cross-Traffic Alert
These driver-assist features are standard across all grades and drivetrains — a competitive advantage over some European rivals that charge extra for comparable technology packages.
Special Appearance Package
For Menifee and Corona drivers seeking exclusivity, the F SPORT Special Appearance Package is a limited-production option available on IS 350 F SPORT models. Only 350 units will be produced for North America. The package includes:
- Exclusive Hakugin Matte White exterior paint
- White-and-black interior treatment
- 19-inch Black BBS forged alloy wheels
- Triple-beam LED headlamps
- F Sport Handling Package (Adaptive Variable Suspension, Torsen LSD on RWD, additional Sport modes)

Frequently Asked Questions
Is the rear seat large enough for three adults?
The IS 350 seats five passengers, but with 32.2 inches of rear legroom, the back seat is best suited for two adults or children. Shoppers needing frequent adult rear-seat transport should compare the IS to the larger Lexus ES sedan.
What is the difference between the RWD and AWD transmissions?
Rear-wheel-drive models use an 8-speed Sport Direct-Shift automatic for a more performance-oriented feel. All-wheel-drive models pair the V6 with a 6-speed automatic tuned for the rear-biased AWD system, prioritizing traction and stability.
Does the F SPORT Design include the Adaptive Variable Suspension?
No. The Adaptive Variable Suspension is part of the optional F Sport Handling Package, which is available exclusively on the full F SPORT grade. The F SPORT Design focuses on the visual and comfort elements of the F SPORT identity.
Is the Mark Levinson audio system available?
Yes. The 17-speaker Mark Levinson premium surround sound system is an available option on the F SPORT and comes standard on the Special Appearance Package. It provides a significant upgrade over the standard 10-speaker system.
