2020 Mercedes-Benz GLS 450 4MATIC – Luxury, Power & Prestige for Life in the GTA

Discover Full-Size Luxury That Moves with Grace

If you're shopping for a full-size luxury SUV that makes no compromises — not on performance, not on comfort, not on presence — the 2020 Mercedes-Benz GLS 450 4MATIC is exactly what you're looking for. Finished in clean White and featuring a 3.0L turbocharged inline-6 with EQ Boost mild hybrid technology, this seven-passenger SUV delivers smooth, confident power and world-class refinement. With 4MATIC AWD, a panoramic roof, and premium interior finishes, it’s built for those in Toronto, Etobicoke, Vaughan, Mississauga, and across the GTA who demand more from every drive.

Sophisticated Looks That Set the Standard

From its sleek LED headlights to its striking alloy wheels, the 2020 GLS 450 defines modern Mercedes-Benz design. A bold stance and clean body lines reflect its commanding presence, while the power liftgate makes everyday utility feel premium. Whether you're pulling up at a business meeting in North York or heading for a family getaway from Brampton to Barrie, this SUV makes an impression before you even step out.

Where Comfort Meets Cutting-Edge Innovation

Inside, you’ll find the refined calm of a black leather-appointed cabin complete with power-adjustable heated seats, tri-zone climate control, and the flexibility of third-row seating. The panoramic sunroof fills the cabin with natural light, enhancing the open, airy feel. Whether you're heading to the cottage from Richmond Hill or picking up the kids in Milton, the GLS 450 turns every trip into a relaxing experience.

Advanced Safety and Driving Intelligence

The 2020 GLS 450 doesn’t just protect — it predicts. Featuring a backup camera, parking sensors, lane assist, automatic parking, and brake assist, this SUV is designed to keep you and your passengers safe, no matter the road or weather. And thanks to 4MATIC all-wheel drive, it's more than ready for Ontario’s four-season conditions — whether you're commuting through Scarborough, navigating Pickering, or driving through Caledon in the snow.

Next-Level Tech & Entertainment

Equipped with Bluetooth connectivity, navigation, Wi-Fi hotspot, and Apple CarPlay/Android Auto, the GLS keeps you effortlessly connected. Crank up the satellite radio, stay in sync with your calendar, and let the infotainment suite guide you through Thornhill traffic or a scenic weekend escape to Stouffville. Everything is intuitive, responsive, and tailored to how you live today.

Beats the Competition in Space, Smoothness, and Prestige

When compared to other luxury 3-row SUVs like the BMW X7, Audi Q7, or Lincoln Aviator, the GLS 450 4MATIC rises above with its mild hybrid technology, signature ride quality, and expansive cabin. The available third-row, heated seats, and intuitive MBUX infotainment system bring true versatility, comfort, and user-friendliness together like no other. This is prestige that performs — without pretension.
