Vehicle type
Use this point as a practical conversation starter when comparing both luxury three-row models and deciding what to test next.
- 2026 Mercedes-Benz GLS: Known as the "S-Class of SUVs," it prioritizes maximum cabin space, smooth ride isolation, and effortless presence everywhere from Uptown Normal to country club outings. Ask our team to demonstrate its exceptionally plush ride quality during your test drive.
- 2026 BMW X7: Focuses slightly more on a firmer, driver-centric feel, but sacrifices some interior passenger stretch-out room as a result. Ask our team to let you compare rear seat entrance and comfort between both.
Engine
Compare how each model responds during daily acceleration, highway passing, and long road trips across Central Illinois.
- 2026 Mercedes-Benz GLS: Offers a silky 375 hp inline-6 turbo with mild-hybrid assist, plus a massive V8 upgrade scaling up to 603 hp in AMG® models. Feel how effortlessly it surges up to speed on Interstate 74.
- 2026 BMW X7: Starts with a matching 375 hp inline-6, but its top-tier V8 stops at 523 hp, falling well short of the AMG® GLS performance ceiling. Test its power delivery on open highway stretches during your visit.
Transmission
This detail shapes low-speed smoothness around town, highway cruising RPMs, and gear transition comfort during your drive near Normal.
- 2026 Mercedes-Benz GLS: 9G-TRONIC 9-Speed Automatic. Delivers ultra-smooth, almost imperceptible gear transitions that prioritize serene passenger comfort and fuel efficiency during long highway cruises. Try accelerating from a stop to experience its refined power delivery.
- 2026 BMW X7: 8-Speed Sport Automatic. Shifts quickly with a firmer, more athletic gear engagement that feels sporty but can lack the creamy smoothness of the Mercedes 9-speed. Experience how both handle stop-and-go driving along Veterans Parkway.
Seating capacity
Evaluate real-world passenger legroom for family and friends.
- 2026 Mercedes-Benz GLS: Seats up to 7 passengers with standard adult-friendly legroom in all three rows, or opt for second-row captain's chairs. Experience how easily adults can sit comfortably in the third row without feeling cramped.
- 2026 BMW X7: Seats up to 7, but its third row offers noticeably tighter legroom and lower seat cushions best reserved for small children on shorter trips. Test third-row accessibility with your family in person.
