Verdict
The 2026 E-Class earns a five-star NHTSA overall safety rating and offers one of the best driver-assistance suites available, wrapped in a serene, luxurious cabin. The IIHS moderate overlap test flagged a rear-passenger restraint issue — worth noting for buyers who frequently carry passengers in the back seat. Ownership costs are among the highest on the platform. For luxury buyers who prioritize highway comfort and ADAS, the E-Class delivers — with a footnote on rear-seat safety.

Combines real-world energy efficiency (EPA-verified MPG or MPG-equivalent vs. class) with long-term ownership confidence (warranty coverage, platform maturity, and reliability data). Methodology →
Driver Assistance
Modest driver-assistance capability, but highway support and parking convenience and hands-free automation are limited.
💡 Tracks where the car can drive itself (highways vs. local roads) and how much driver supervision is needed (up to fully driverless).

Combines highway support, parking convenience, and hands-free automation capability into one score. Methodology →
Livability
Passenger space and everyday maneuverability, scored within its class.
Combines how comfortably this vehicle fits passengers and cargo with how easily it maneuvers in real-world conditions — normalized within its Sedan segment for fair comparison. Methodology →
Safety
Based on standard crash-avoidance features.
Combines crash-test protection — NHTSA frontal, side, and rollover ratings plus the IIHS crashworthiness sub-tests (small- and moderate-overlap front, side, headlights) — with standard crash-avoidance technology. New model years without published crash tests are scored on crash-avoidance features alone and capped until tested. Methodology →
