Interior Features That Define Premium Cars in 2025 – What to Look For

When you hear the term “premium car,” performance might spring to mind. But in 2025, it’s often what’s inside that truly sets luxury vehicles apart. From AI-powered infotainment to sustainably sourced materials, today's top-tier cars offer a refined, smart, and immersive cabin experience. Whether you’re browsing high-end sedans, electric crossovers, or performance SUVs, interior features are where brands showcase their finest craftsmanship and tech innovations.

In this blog, we explore the most defining interior features that separate the premium class from the rest in 2025 Australia – what they are, why they matter, and which models do it best.

1. Smart Infotainment Systems: The Brain of the Cabin

Modern premium interiors revolve around technology – and the centerpiece is the infotainment system. In 2025, these systems are more than just touchscreens; they are AI-powered control centers.

Key Highlights:

• AI Voice Assistants (like BMW’s Intelligent Personal Assistant or Mercedes MBUX)
• Integrated Streaming Services (Spotify, YouTube, Netflix – with screens for rear passengers)
• Over-the-Air (OTA) Updates – your software evolves just like your smartphone
• Multi-screen Dashboards – dual or triple displays are common, especially in EVs like the Tesla Model S or BYD Seal

Notable Mentions:

• 2025 Audi Q8 e-tron – MMI touch response system is ultra-responsive
• 2025 Genesis GV70 – minimalist UI with rich functionality
• 2025 Mercedes-Benz EQE – MBUX Hyperscreen that stretches across the entire dash

2. Sustainable & Premium Materials – Eco Meets Elegance

Eco-consciousness isn’t just for hybrids anymore. Even petrol-powered luxury vehicles are going green inside.

Trending Interior Materials in 2025:

• Recycled PET fabrics
• Natural wool-blend seat covers
• Leather-free vegan options (as seen in Volvo EX90 or Polestar 3)
• Sustainably sourced wood trims

Luxury Meets Sustainability:

• Tesla Model Y – vegan interiors
• BMW i7 – cashmere blend and Merino leather combo
• Lexus RX 500h – bamboo-inspired trims and ultrasuede touches

Consumers increasingly expect their vehicles to reflect their environmental values without compromising on luxury feel.

3. Massaging & Climate-Controlled Seats

Comfort isn't just about soft leather anymore. High-end cars are now offering seats that think and adapt.

Features to Look for:

• Multi-zone seat massagers – customizable settings

• Memory foam or air-cushion layering

Top Performers:

• Mercedes-Benz S-Class – industry benchmark for seat massage
• Range Rover Autobiography – airline-style rear lounge seats

4. Ambient Lighting: The Mood Setter

Ambient lighting in 2025 is more than a gimmick. It has evolved into a crucial component of the luxury experience – influencing mood, enhancing aesthetics, and even increasing visibility at night.

Key Innovations:

• 64+ colour options
• Music-synced lighting modes
• AI-adaptive lighting that changes based on time of day or driving mode

Brands Leading the Trend:

• Mercedes EQ range – customizable lighting profiles
• Kia EV9 – futuristic, multi-zone ambient glow

5. Advanced Climate Control & Air Quality

As Australia continues to face dust storms, allergens, and increasingly hot summers, in-cabin air quality has become a major focus for carmakers.

What’s New:

• Four-zone climate control
• PM2.5 air filtration systems
• Ionizers and fragrance diffusers (especially in BMW, Mercedes, Genesis)
• Rear-seat climate touch panels

Luxury now includes breathing purified air and personalizing cabin fragrance profiles.

6. Acoustic Engineering – Silence is Premium

Quietness equals quality in the premium segment. In 2025, brands go to extreme lengths to reduce NVH (noise, vibration, harshness).

Innovations:

• Double or triple-laminated glass

• Acoustic foam insulation throughout the cabin
• EV-specific sound dampening to combat road noise

Leading Models:

7. Rear Passenger Luxury – No Longer an Afterthought

Traditionally, rear-seat space was utilitarian. Today, it’s a lounge.

Premium Rear Cabin Additions:

• Individual climate control
• Reclining lounge chairs with footrests
• Tablet or touchscreen controls
• Power sunshades and executive tables

Best for Rear Comfort:

• BMW 7 Series – full recline and theatre screen
• Lexus LM – luxury MPV designed to rival private jets

Features Gaining Momentum:

• Hand gesture controls for volume, answering calls, etc.
• Haptic feedback on buttons or sliders

These subtle enhancements create a futuristic, intuitive user experience.

This all contributes to a clean, uncluttered premium feel.

11. In-Car Personalisation & AI Integration

Cars in 2025 are beginning to know their drivers.

Customisation Examples:

• Driver profiles that remember seat, mirror, climate, and music preferences

• Predictive AI that suggests destinations, rest stops, or parking

BMW’s MyModes and Tesla’s driver profiles are top-tier examples.

Natural light plays a big role in interior luxury. In 2025, panoramic roofs are now the norm in the premium segment.

Innovations:

• Full-length glass roofs with UV protection

• Bang & Olufsen (Audi, Ford Mustang Mach-E)
• Mark Levinson (Lexus)
• Bowers & Wilkins (Volvo, BMW)
• Burmester (Mercedes-Benz)

Expect 14 to 28 speakers, 3D spatial surround sound, and vibration speakers built into seats.

High-Quality Touchpoints:

• Metal-finished knobs
• Leather-wrapped steering wheels with heating
• Piano black or matte wood trims
• Soft-touch door panels

Design cohesion across screens, vents, and trims reflects attention to detail – a hallmark of premium design.

15. Future Interior Trends to Watch

As 2025 progresses and the 2030 vision draws closer, expect:

• Integrated gaming and productivity modes in EVs (like Tesla Arcade or BYD Lounge Mode)
• Bio-metric security systems (fingerprint or facial recognition ignition)
