Geely’s 45 km/l i-HEV Sets Guinness-Verified Efficiency Record

Geely – Recently, the Chinese automaker pulled the wraps off its new i-HEV “Intelligent Energy” hybrid powertrain, promising a jaw-dropping 45 km/l and a Guinness-certified 48.4 % thermal efficiency that could upend the global efficiency leaderboard.

  • In short: Geely’s i-HEV rivals the fuel burn of small motorcycles while delivering up to 313 hp.

How the AI-Driven Drivetrain Reaches Motorcycle-Level Economy

The i-HEV pairs 1.5- to 2.0-liter hybrid-dedicated engines with an “11-in-1” electric unit and an AI energy-management brain said to improve overall efficiency by more than 10 %. According to Car and Driver data, today’s best conventional hybrids average roughly 25–30 km/l, giving Geely a sizeable lead on paper.

The system can unleash up to 230 kW (313 hp), allowing crossovers such as the Monjaro to sprint while sipping fuel. Early WLTC figures show 3.98 L/100 km (25 km/l) for the Preface sedan and 4.75 L/100 km (21 km/l) for the larger Monjaro, and Geely says further software updates will push those numbers closer to the headline 45 km/l in lighter models due in 2026.

“The technology achieves 48.4 % thermal efficiency, one of the highest ever recorded for a series-production combustion engine, certified by Guinness World Records,” Geely stated.

Why This Record Matters in the Global Hybrid Race

With Chinese incentives tilting away from plug-ins and battery costs still stubbornly high, full hybrids are regaining favor. Toyota moved 4.4 million hybrids in 2025—about 42 % of its sales—while the International Energy Agency forecasts worldwide hybrid deliveries could top 9 million units in 2027, nearly doubling 2023 volumes.

Geely’s early-2026 rollout across high-volume models such as Emgrand sedans and Boyue SUVs positions the brand to ride that wave. Smaller battery packs (1–2 kWh) mean lower rare-earth demand and price exposure, and Geely is hedging further by investing in alternative fuels like methanol, touted by chairman Li Shufu for its superior energy density.
