The Toyota Crown Signia vs. the Lexus RX350

Deciding which luxury SUV to buy can be daunting when you have two strong contenders, such as the Toyota Crown Signia and the Lexus RX350, to pick from. These two midsize SUVs seem similar, with the Crown Signia taking many exterior styling cues from the Lexus, but beyond their outward similarities, they have unique features that make them stand out from each other and the competition. In this comparison, we dive deep into these luxury SUVs’ features and specs to discover how they compare. 

Exterior Design 

The 2025 Crown Signia’s updated exterior is more stunning than ever. Its sleek lines give it a modern look, and its luxurious front grille has a commanding presence. It also features elegant LED daytime running lights. 

The Lexus RX350 has an equally stunning exterior with flowing, sophisticated lines. Its luxurious front end includes an expressive front grille and LED headlights, and its rear makes a strong impression with a futuristic LED Blade taillamp.

Powertrains

The new Crown Signia and the Lexus RX350 both feature robust powertrains with distinct configurations. 

Hybrid Options

The Crown Signia uses a 2.5-liter inline-four gas engine with an electric drive motor. This traditional hybrid setup delivers an impressive 240 horsepower. Along with this hybrid powertrain, the Crown Signia features Toyota’s Electronic On-Demand All-Wheel Drive (AWD) system, which sends up to 80% of power to the rear wheels and can switch to front-wheel drive for optimal fuel efficiency. 

While the standard Lexus RX350 doesn’t have a hybrid engine, it still offers a formidable powertrain. It runs on a 2.4-liter turbocharged inline-four engine and outputs 275 horsepower. Like its predecessor, the 2025 RX350 also has a hybrid sibling, the RX350h, which has a 2.5-liter inline-four hybrid setup that delivers 246 horsepower.

Fuel Efficiency

With its hybrid engine and adaptable AWD system, the Crown Signia achieves estimated EPA ratings of 39 city mpg, 37 highway mpg, and 38 combined mpg.

While EPA hasn’t rated the 2025 Lexus RX350, the model will likely maintain its reputation as one of the most fuel-efficient vehicles in the midsize luxury SUV segment, based on stats from the 2024 model. When paired with a front-wheel drivetrain, the 2024 RX350 gets estimated EPA ratings of 22 mpg city and 29 mpg highway. Meanwhile, AWD models have estimated ratings of 21 mpg city and 28 mpg highway.

Interior and Comfort 

The 2025 Toyota Crown Signia’s beautiful cabin provides many creature comforts. Despite being the base trim, the XLE model has heated and ventilated front passenger seats to ensure you and your front passenger ride in ultimate comfort. The heated rear seats also keep passengers sitting in the back comfortable during nighttime drives. Other comfort features available on the new Crown Signia include a heated steering wheel and a fixed panoramic roof.

Every square inch of the RX350’s interior space uses premium materials, from open-pore wood trims to luxury leather seats. The standard model comes with heated and ventilated front and rear seats and a leather-trimmed steering wheel and shift knob. That said, the model’s most outstanding interior feature is its thematic ambient lighting system that lets you personalize your cabin with up to 14 preset themes.

Storage

When it comes to cargo space, the Crown Signia has a slight edge over the Lexus RX350. With all seats upright, it provides 25.8 cubic feet in the trunk, while folding the rear seats expands its capacity to 68.8 cubic feet. The Lexus RX350 offers 29.6 cubic feet behind the second row and a total of 46.2 cubic feet with the rear seats folded down.

Technology and Safety 

The new Crown Signia and the RX350 both offer top-of-the-range technologies to take the driving experience to new heights. The centerpiece of the Crown Signia’s infotainment system is a 12.3-inch touch screen with wireless Apple Car Play and Android Auto compatibility. Other noteworthy features include a 12.3-inch digital information center, a panoramic view monitor, and a digital rearview camera with HomeLink. An 11-speaker JBL audio system with a subwoofer and amplifier also comes standard on the Limited trim to provide an immersive listening experience on the road.

The Lexus RX350 offers an equally impressive technology suite, starting with a 14.0-inch display with crisp graphics and great responsiveness. Notable available features include a high-definition panoramic view monitor, a digital rearview mirror, and a Mark Levinson PurePlay surround-sound audio system.

Safety

The Crown Signia comes with the cutting-edge Toyota Safety Sense 3.0 system, which includes a dynamic radar cruise control, lane departure alert, forward collision warning with pedestrian detection, road sign assist, high beams, and more. The RX350’s Lexus Safety System+ 3.0 matches this safety suite with similar features.

Pros and Cons Summary 

The new Toyota Crown Signia and the Lexus RX350 are seemingly matched on nearly every front, with either getting a slight advantage over the other in a few areas. For instance, while the Crown Signia offers slightly better fuel economy, the RX350 wins when it comes to sheer engine power. Similarly, whereas the Lexus has a more luxurious interior, the Toyota has more cargo capacity.
