[Exclusive] All-New Avante Hybrid Achieves Over 10% Increase in Fuel Efficiency Despite Larger Size and Enhanced Performance

Certified at 21.2 km/l Combined with 17-inch Wheels

10.4% Improvement over Previous Model

18-inch Model Surpasses Old 17-inch Efficiency

Maintains Superior Economy with Larger Wheels

Achieves Best-Ever Fuel Efficiency through Enhanced Body Rigidity and Power Output

The official certified fuel efficiency of Hyundai Motor Company’s 'The All-New Avante Hybrid', which was released last month, has been made public. Despite the vehicle’s larger body and improved performance, it has achieved a more than 10% increase in fuel efficiency compared to the previous model, reaching an all-time high level of fuel economy.

According to the automotive industry and Hyundai Motor Company as of September 7, the combined fuel efficiency of the All-New Avante 1.6 gasoline hybrid with 17-inch wheels is 21.2 km/l. This represents an improvement of about 10.42% compared to the 2026 model year Avante hybrid with the same wheel size (19.2 km/l). The 18-inch model is also rated at 19.9 km/l, surpassing the fuel efficiency of the previous model with 17-inch wheels. Typically, larger wheel sizes result in decreased fuel efficiency due to rolling resistance, but the new model has achieved higher efficiency than its predecessor even with larger wheels. Considering that the Prius hybrid model from Toyota, known for its high efficiency, is certified at a combined 20.9 km/l with 19-inch wheels, this places Hyundai’s latest model among the industry’s best in terms of fuel economy.

This improvement in fuel efficiency is particularly significant because it was achieved through simultaneous enhancements to both body rigidity and power performance. Hyundai Motor Company has strengthened crash safety by increasing the proportion of hot-stamped and ultra-high-strength steel with a strength rating of 1 gigapascal (GPa) or more in key body areas, raising it from 52.6% in the previous model to 58.7%. Through advanced technology, Hyundai has overcome the structural limitation that vehicle reinforcement typically leads to increased curb weight.

Power performance has also been significantly upgraded. The new Avante Hybrid combines a third-generation Smartstream 1.6 GDI engine, a drive motor with a maximum output of 45 kW, and a 1.49 kWh high-voltage battery, resulting in a peak output of 157 horsepower—16 more horsepower than the previous model. While it is common for increased output to reduce fuel economy, the new model successfully delivers both enhanced performance and high fuel efficiency.

In addition, Hyundai Motor Company has maximized efficiency by implementing an integrated exhaust manifold cylinder head and a continuous variable oil pump. The company also increased the effective compression ratio for stronger air-fuel mixture compression and introduced a 350 bar high-pressure fuel injection system, improving engine fuel efficiency by about 2.9%.

The price of The All-New Avante Hybrid is set between 30.42 million and 36.99 million won, before eco-friendly vehicle tax benefits are applied. While the price barrier has increased—exceeding 40 million won when additional options are chosen for top trims—the company is focused on appealing to value-conscious consumers by highlighting double-digit fuel efficiency improvements.
