2025 Mercedes-Benz GLA-Class vs 2026 Kia Sorento Plug-In Hybrid

$43,000 · Crossover

$48,290 · Crossover

Comparison Overview

Choosing between a premium compact crossover and a larger, electrified mainstream option often boils down to balancing luxury badge appeal against long-term savings and space. The 2025 Mercedes-Benz GLA-Class starts at a tempting $43,000, offering the prestige factor, but it demands premium unleaded fuel and provides only 221 horsepower. In contrast, the 2026 Kia Sorento Plug-In Hybrid, priced $5,290 higher at $48,290, boasts 261 horsepower and the significant advantage of 30 miles of pure electric range, which drastically impacts daily running costs. While the GLA delivers slightly better fuel economy overall at 29 combined MPG compared to the Kia's 33 combined MPG, the Sorento's PHEV capability combined with its larger AWD platform makes it a compelling all-rounder for buyers needing more utility than the smaller Mercedes.
