When you look at the Lexus GS 350 F Sport AWD, you aren't looking at a stripped-down track monster. You're looking at a heavy, weather-confident luxury cruiser hiding a naturally aspirated 3.5-liter V6 beneath its sharp sheet metal. It hits 0 to 60 mph in roughly 5.8 seconds, a figure that puts it squarely in the middle of the executive sport sedan pack. While rear-wheel-drive variants benefit from an 8-speed automatic transmission, all-wheel-drive models swap in a robust 6-speed automatic to manage power distribution across all four corners.
Understanding how this setup performs requires looking past factory marketing claims and examining real-world weight, mechanical grip, and everyday drivability. Let's break down what makes this sedan tick, where it excels, and where it falls short compared to its German rivals.
Powertrain Mechanics and the AWD Trade-Off
Under the hood sits a 2GR-FSE (or later 2GR-FKS) 3.5-liter V6 engine pushing out 311 horsepower and 280 lb-ft of torque. Unlike the turbocharged four-cylinders common in modern luxury cars, this engine delivers power linearly. You have to rev it out to get the best response, as peak torque arrives higher in the band around 4,800 rpm.
The all-wheel-drive system uses an electronically controlled wet clutch pack to split torque dynamically. Under normal cruising conditions, it sends 100 percent of the power to the rear wheels to maintain a classic rear-drive feel. When slip is detected, or during hard acceleration from a standstill, it can shift up to 50 percent of the power forward.
This traction advantage comes with a distinct penalty: weight. The AWD hardware pushes the curb weight to roughly 3,900 pounds. That extra mass blunts initial acceleration compared to the lighter rear-wheel-drive variants, which is why the AWD model settles into the high-5-second range for the 0-60 sprint.
Real-World Acceleration and Performance Dynamics
Numbers on a spec sheet don't capture how a car behaves on a wet off-ramp or a cracked city street. The 6-speed automatic transmission in the AWD model is older than the units found in modern competitors, but it shifts smoothly and holds gears predictably when you flip the dial to manual mode using the steering-wheel paddle shifters.
- The Launch: From a dead stop, the all-wheel-drive system eliminates wheelspin entirely. You get clean, drama-free bite, though you can feel the car gathering its mass before it builds serious momentum.
- Mid-Range Pull: Passing power at highway speeds is where the V6 shines. Dropping down a gear puts the engine right into its powerband, making short work of slower traffic.
- Handling Balance: The F Sport package adds adaptive variable suspension, stiffer springs, and larger brakes with 14-inch front rotors. While it doesn't mask the car's physical heft completely, body roll is well-controlled in Sport S+ mode.

Common Mistakes When Driving and Maintaining the GS 350 AWD
Drivers transitioning from lightweight sports cars or high-torque turbo-diesels often make specific errors when trying to extract performance from this platform.
- Treating it like a turbo car: Don't look for low-end punch at 1,500 rpm. This engine needs revs. If you want immediate response, you have to keep the transmission in a lower gear.
- Ignoring fluid changes in the transfer case: Because the AWD system relies on a front power take-off unit and a transfer case, changing the gear oil every 60,000 miles is mandatory if you want to avoid expensive drivetrain whine.
- Overestimating winter grip on stock tires: The AWD system helps you pull away in the snow, but it won't help you stop or corner any better than your tires allow. Budget for a proper set of dedicated winter rubber if you live in a cold climate.
Frequently Asked Questions
Can the 6-speed automatic be tuned for faster shift times?
While some aftermarket tuners offer software flashes to alter shift mapping, the gains are marginal compared to modern dual-clutch or fast-shifting 8-speed units. The stock transmission prioritizes long-term durability and smoothness over lightning-fast track shifts.
Why does the AWD model use a 6-speed instead of the 8-speed?
Packaging constraints in the transmission tunnel forced Lexus to retain the older, sturdier 6-speed automatic to accommodate the physical hardware required for the front propshaft and differential housing.
How does the F Sport suspension affect daily ride comfort?
In Normal mode, the ride is firm yet composed, absorbing harsh potholes adequately. In Sport S+, the damping tightens noticeably, which can feel jittery on rough city pavement but provides excellent stability on smooth, winding roads.
What kind of fuel economy can I realistically expect?
EPA ratings sit at 19 mpg city and 26 mpg highway. In heavy stop-and-go urban commuting, expect closer to 17 or 18 mpg due to the vehicle's weight and the friction of the mechanical all-wheel-drive system.
