Driving experience

BMW iX3

The iX3 is refined and composed rather than playful. Steering is accurate and reasonably weighted, body control is good, and the car feels stable and secure at speed. Ride quality is firm but generally well-controlled — better than many early EVs on adaptive suspension, though larger wheels and the M Sport suspension make it busier over poor surfaces. Instant torque makes it quick off the line, and the single-motor rear-drive layout gives balanced, predictable handling without the artificial feel of some dual-motor systems. Cabin noise is low; wind and tyre roar are the main sounds at motorway speeds. Regenerative braking is strong and well-calibrated (one-pedal driving is possible). Overall it drives like a polished, slightly firmer X3 with electric silence and response — competent and relaxing rather than involving.

Mercedes-Benz GLE

Serene, isolating and quietly opulent. Steering is light and relaxed, the ride hushed and composed, and the GLE smothers rough roads and motorway miles alike. 4MATIC adds unflappable all-weather security without asking anything of the driver. AIRMATIC air suspension, where fitted, glides over poor surfaces with real polish. The M256 inline-six is silky with its 48-volt assist, the OM654/OM656 diesels pull strongly and stay quiet, and the GLE 400 e plug-in glides on electric power. The 9G-Tronic shifts almost imperceptibly. Overall a calm, tech-rich luxury SUV built to isolate, not involve.
