The Lexus RX 350 Hybrid needs premium fuel, right?
The 2020 Lexus RX 350 is a spotless luxury car, but it also gets surprisingly good gas mileage. Although it doesn’t require premium gas, it provides premium performance. Fuel with an octane rating of 87 is advised for all options.
Hybrid MPG
The increased fuel efficiency is the primary benefit of choosing a hybrid. Compared to the RX 350’s remarkable 19/26 mpg city/highway ratings, the RX 450h achieves impressive 31 mpg in city driving and 28 mpg on the highway. The RX hybrid’s starting price premium of only $1,250 over the non-hybrid variant makes it even more alluring. (Just keep in mind that the RX 450h demands premium fuel.)
Elegant Cabin
Lexus is skilled in designing a sophisticated and (usually) user-friendly interior. High-quality components, soft-touch surfaces, and muted controls give the product a really premium look and feel. We observed the spacious front and rear seats, as well as the ample cargo capacity, when we were driving.
No Weird Driving Manners
The gas-electric powertrain doesn’t run out of steam when you need some rapid acceleration thanks to its 308 total system horsepower. Even better, the RX 450h doesn’t behave like a hybrid at all. The RX 450h gets the job done without the strange chirps, whirrs, and buzzes that frequently plague other hybrid vehicles, although there is the occasional drone from the engine. During our test drive, the brake pedal also received acclaim for its comfortingly smooth and linear action, which is far better than that of previous hybrid Toyota vehicles we’ve experienced.
Winning Infotainment System
The announcement was significant for the 2020 model year, but it ought to be acknowledged again. Long delayed touchscreen controls were added to the RX. Previously, the console’s touchpad served as the sole means of controlling the infotainment system. The available touchscreens, which range in size from 8 to 12.3 inches depending on the model, mean that even while the dreadful touchpad is still present, you won’t ever need to use it.
Standard Safety Features, Top Marks in Crash Tests
In Insurance Institute for Highway Safety crash tests, the 2021 Lexus RX range, including the hybrid (but excludes three-row L models), receives the best possible ratings. The 2021 RX 450h now comes standard with rear cross-traffic alert and blind spot monitoring as active safety features. The Safety System Plus 2.0, as it is known by Lexus, also includes a long list of other standard safety measures.
Sportier F Sport, if That’s Your Thing
Alloy wheels and aluminum trim elements dotted over the exterior and inside of the F Sport trim option give the RX 450h a bit more swagger. Although the modifications to the suspension and steering are minor, a handling package is offered. If you enjoy the way the F Sport looks, that’s fantastic; if you’d rather save money and are OK with the way the basic 450h looks and has slightly less athletic dynamics, that works, too.

When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.

Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.

Can the Lexus 450h handle snow?
I have to give the car’s all-wheel-drive system some credit, even though its all-season tires gripped the pavement like an eagle’s talons snatched its prey. The drive system never let me down, and it runs extremely quietly as well. I pounded the throttle at every stop and even performed standing starts on hills.
Additionally, my test vehicle has parking sensors and “Intuitive Parking Assist with a Panoramic View,” to use Lexus’s technical term. I was able to see both sides of the car, with a major concentration on the front to see where I’m going, which was helpful when parking in a small area covered in snow. Overall, no matter what you throw at the 2021 Lexus RX 450h, it performs admirably in the snow.
