2026 Lexus IS 350 F SPORT vs. F SPORT Design AWD: Which Trim Is Worth It?
The 2026 Lexus IS 350 comes in two grades, and both are available with all-wheel drive. They share an engine, a chassis, a screen layout and a safety suite. What separates them is a short list of hardware the F SPORT Design cannot be given at any price. If you want adaptive suspension, a limited-slip differential or ventilated seats, the full F SPORT is the only way in.
The Short Answer: What You Are Choosing Between
Step from the IS 350 F SPORT Design AWD to the IS 350 F SPORT AWD and the engine does not change. Neither does the transmission, the wheelbase, the wheel size or the standard safety equipment.
The gap is $2,450 in MSRP. For that, the F SPORT adds heated and ventilated bolstered front seats and a power driver’s seat with memory. More importantly, it is the only grade eligible for the F SPORT Handling Package. That package is the real dividing line between the two cars.
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.
For Temecula and Murrieta drivers who treat the IS as an everyday commuter, the F SPORT Design AWD is a complete, well-equipped luxury sedan. For drivers who want the chassis to match the styling, the Design grade is a dead end. The hardware is simply not offered on it.

Performance: Same Engine, Different Chassis Potential
The Shared Powertrain
Both grades run the same naturally aspirated 3.5-liter V6, rated at 311 horsepower at 6,600 rpm and 280 lb-ft of torque at 4,800 rpm. All-wheel-drive models pair that engine with a six-speed automatic. Rear-wheel-drive models use an eight-speed. Top track speed is 143 mph either way. On paper these two cars accelerate identically, because mechanically they do.
| Specification | IS 350 F SPORT AWD | IS 350 F SPORT Design AWD |
|---|---|---|
| Engine | 3.5L V6 | 3.5L V6 |
| Horsepower | 311 hp @ 6,600 rpm | 311 hp @ 6,600 rpm |
| Torque | 280 lb-ft @ 4,800 rpm | 280 lb-ft @ 4,800 rpm |
| Transmission | 6-speed automatic | 6-speed automatic |
| Drivetrain | All-wheel drive | All-wheel drive |
| Top track speed | 143 mph | 143 mph |
| EPA-Estimated MPG | 19 city / 26 hwy / 22 combined | 19 city / 26 hwy / 22 combined |
| EPA-Estimated total range | 383 miles | 383 miles |
| Fuel | Premium unleaded | Premium unleaded |
| Fuel tank | 17.4 gal | 17.4 gal |
| F SPORT Handling Package | Available | Not available |

The F SPORT Handling Package
That last table row is the whole comparison.
The F SPORT Handling Package is offered only on the IS 350 F SPORT and IS 350 F SPORT AWD. It adds an Adaptive Variable Suspension that continuously adjusts damping, a Torsen limited-slip rear differential, and Drive Mode Select with Eco, Normal, Sport S, Sport S+ and Custom modes. The result rides softly on a freeway commute and tightens up on the two-lane roads through Temecula Valley wine country. It is a genuinely different machine depending on which mode you pick.
The F SPORT Design AWD keeps its sport-tuned suspension and its F SPORT exterior treatment. But there is no option box, no dealer-installed path, and no package that adds adaptive damping or the limited-slip differential to it. The styling is the same. The chassis is not.
Equipment: What Separates the Two Grades
Most of this car is identical across both grades. The table below shows exactly where that stops.
| Equipment | IS 350 F SPORT | IS 350 F SPORT Design |
|---|---|---|
| 3.5L V6, 311 hp | Standard | Standard |
| 19-inch alloy wheels | Standard | Standard |
| NuLuxe upholstery | Standard | Standard |
| Heated front seats | Standard | Standard |
| 12.3-inch touchscreen | Standard | Standard |
| 12.3-inch digital instrument cluster | Standard | Standard |
| 10-speaker Lexus Premium Sound | Standard | Standard |
| Lexus Safety System+ 3.0 | Standard | Standard |
| 10 airbags | Standard | Standard |
| Ventilated front sport seats | Standard | Not available |
| Power driver’s seat with memory | Standard | Not available |
| F SPORT Handling Package | Available | Not available |
| Technology Package | Available | Not available |
Driver-assistance and advanced safety systems are supplemental aids and are not substitutes for safe and attentive driving. Availability, operation, and effectiveness vary by trim and equipment and depend on factors including road, weather, traffic, and vehicle condition. Always keep your hands on the wheel and your eyes on the road. See your owner’s manual for system limitations and details.
Seating
Both grades are trimmed in NuLuxe synthetic leather with heated front seats standard. The F SPORT adds bolstered front sport seats that are both heated and ventilated, plus a power driver’s seat with memory. The F SPORT Design does not offer ventilated seats at any price. Its driver’s seat has no memory function either. In a two-driver household, that means somebody is adjusting the seat every time they get in.
Audio, Displays and Factory Options
Technology is one area where the Design grade gives up almost nothing. Every 2026 IS 350 comes with Lexus Interface on a 12.3-inch touchscreen, a 12.3-inch digital instrument cluster, wireless Apple CarPlay and Android Auto, and the standard 10-speaker Lexus Premium Sound system. Newly styled 19-inch alloy wheels are standard on both grades.
Beyond that, the F SPORT is the grade built to be optioned up. The 17-speaker Mark Levinson system is available as a factory option, as are a Power Rear Sunshade and Triple-Beam LED headlamps. The Technology Package, which adds Lane Change Assist, Traffic Jam Assist and Front Cross-Traffic Alert, is available on the F SPORT. So is the Handling Package. Intuitive Parking Assist, Rear Cross-Traffic Braking and the Panoramic View Monitor can be fitted to either grade.
Safety: A Shared Baseline
Every 2026 Lexus IS comes standard with Lexus Safety System+ 3.0, new for this model year and a step up from the previous generation of the suite. Per the Lexus USA Newsroom, it includes:
- Pre-Collision System with Pedestrian Detection
- Full-Speed Dynamic Radar Cruise Control
- Lane-keeping assistance
- Automatic High Beams
- Road Sign Assist
- Proactive Driving Assist
Blind Spot Monitor with Rear Cross-Traffic Alert and 10 airbags are standard on both grades. Intuitive Parking Assist, Rear Cross-Traffic Braking and the Panoramic View Monitor are available on either grade.
On crash testing, be clear-eyed. The IIHS rates the 2026 IS Good for small overlap front protection and Good for headlights. It rates Marginal in the updated moderate overlap front test and Acceptable in the updated side test. The car does not currently hold a Top Safety Pick award.
Driver-assistance and advanced safety systems are supplemental aids and are not substitutes for safe and attentive driving. Availability, operation, and effectiveness vary by trim and equipment and depend on factors including road, weather, traffic, and vehicle condition. Always keep your hands on the wheel and your eyes on the road. See your owner’s manual for system limitations and details.
Cabin Space and Cargo
Interior dimensions are shared across both grades.
| Measurement | 2026 Lexus IS 350 |
|---|---|
| Seating capacity | 5 |
| Wheelbase | 110.2 in |
| Front headroom | 38.2 in |
| Rear headroom | 36.9 in |
| Front legroom | 44.8 in |
| Rear legroom | 32.2 in |
| Front shoulder room | 55.9 in |
| Rear shoulder room | 53.4 in |
| Front hip room | 54.3 in |
| Rear hip room | 54.0 in |
| Trunk capacity | 10.8 cu ft |
The IS is a compact sport sedan and it measures like one. Front-seat space is generous, rear legroom is tight, and the 10.8-cubic-foot trunk handles a weekend’s luggage rather than a family’s. A split-folding rear bench with a center armrest extends that capacity for longer items.
Frequently Asked Questions
Is the 2026 IS 350 F SPORT AWD worth $2,450 more in MSRP than the F SPORT Design AWD?
It depends entirely on whether you want the Handling Package. At $51,345 MSRP versus $48,895 MSRP, the F SPORT adds ventilated front seats and a memory driver’s seat, which are useful but not transformative. What justifies the step up is eligibility. The Adaptive Variable Suspension, Torsen limited-slip differential and Technology Package cannot be added to the Design grade under any configuration. If none of those interest you, the F SPORT Design AWD is the better value.

Do both grades have the same engine and fuel economy?
Yes. Both use the 3.5-liter V6 producing 311 horsepower and 280 lb-ft of torque, paired with a six-speed automatic and all-wheel drive. EPA-Estimated fuel economy for both AWD grades is 19 MPG city, 26 MPG highway and 22 MPG combined on premium unleaded, with an EPA-Estimated total range of 383 miles.
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.
What are the main interior differences between the two grades?
Two things, and both involve the front seats. The F SPORT has ventilated front seats, and the F SPORT Design does not offer them. The F SPORT has a power driver’s seat with memory, and the F SPORT Design does not. Both grades share NuLuxe upholstery, heated front seats, the same 12.3-inch displays and the same 10-speaker Lexus Premium Sound system.
Which grade is better for wet or hilly roads around Temecula Valley?
Both handle wet pavement and elevation changes well on all-wheel drive. The F SPORT pulls ahead only when equipped with the Handling Package, whose Adaptive Variable Suspension adjusts damping continuously to limit body roll through corners while staying comfortable over rough surfaces. Without that package, the two AWD cars behave very similarly.
Where can I test drive the 2026 Lexus IS 350?
Both grades can be driven at Temecula Valley Lexus, 42081 DLR Drive, Temecula, CA 92591. Call our sales team at 951-297-3896 to schedule a back-to-back comparison. Driving the two grades on the same roads is the fastest way to tell whether the Handling Package is worth it to you.
The Verdict
The 2026 IS 350 F SPORT Design AWD is the value pick, and for most buyers it is enough car. Same 311-horsepower V6, same screens, same Lexus Safety System+ 3.0, same 19-inch wheels, and $2,450 less in MSRP.
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.

Always keep your hands on the wheel and your eyes on the road. See your owner’s manual for system limitations and details.
The 2026 IS 350 F SPORT AWD earns our recommendation anyway. Not because of the ventilated seats, but because it is the only version of this car that can be optioned into a true sport sedan. Adaptive damping and a limited-slip differential are not features you can add later. You either buy the grade that allows them or you do not.
