The Li ONE, launched in October 2019 and produced through May 2021, marked a significant entry into the rapidly expanding Chinese New Energy Vehicle (NEV) market. Positioned as a premium extended-range electric SUV, the Li ONE (also known as the Ideal ONE) aimed to bridge the gap between fully electric vehicles and traditional gasoline-powered cars by combining a substantial battery capacity with a small gasoline engine serving as a range extender. The 1.2T 40.5 kWh variant, delivering a combined system output of 326 horsepower and all-wheel drive, was the sole configuration offered throughout its production run, defining the Li Auto brand during its initial phase. It was designed to appeal to families desiring a spacious, technologically advanced, and relatively long-range electric vehicle without the concerns associated with limited charging infrastructure.

Powertrain & Engine Architecture
The Li ONE employs a distinctive powertrain configuration. It’s fundamentally a series hybrid, meaning the 1.2-liter turbocharged three-cylinder DAM12TD engine doesn’t directly power the wheels. Instead, it functions solely as a generator, charging the 40.5 kWh lithium-ion battery pack. This battery then powers two electric motors – one driving the front wheels and another driving the rear wheels, providing all-wheel drive capability. The engine produces 131 horsepower at 5500 rpm and features direct injection and a turbocharger with intercooling. The engine’s primary role is to extend the vehicle’s range when the battery is depleted, alleviating range anxiety. The single-speed automatic transmission is directly connected to the generator, simplifying the mechanical layout. The electric motors themselves are synchronous motors, with the rear motor being more powerful (190 hp) than the front (136 hp), contributing to a slightly rear-biased torque distribution.
Driving Characteristics
The Li ONE’s driving experience is largely defined by its electric powertrain. Acceleration is brisk, achieving a 0-60 mph time of approximately 6.2 seconds, thanks to the combined output of 326 horsepower and the instant torque delivery of the electric motors. In all-electric mode, the vehicle offers near-silent operation and smooth acceleration. When the gasoline engine engages, it does so relatively seamlessly, although a noticeable change in engine note is present. The single-speed transmission provides linear acceleration, but lacks the gear changes found in traditional automatic transmissions. Compared to potential future higher-performance variants, the 1.2T model prioritizes efficiency and smooth operation over outright speed. The all-wheel drive system provides confident handling in various weather conditions.
Equipment & Trim Levels
As the sole configuration offered, the Li ONE 1.2T 40.5 kWh came standard with a comprehensive suite of features. Interior appointments included seating for six or seven passengers, depending on the configuration, and premium materials throughout the cabin. Standard equipment included a large touchscreen infotainment system, advanced driver-assistance systems (ADAS) such as adaptive cruise control and lane keeping assist, and a panoramic sunroof. Optional extras included upgraded interior trim packages, premium audio systems, and additional ADAS features. The emphasis was on delivering a luxurious and technologically advanced experience.
Chassis & Braking
The Li ONE features an independent suspension system at all four corners, utilizing McPherson struts at the front and a multi-link setup at the rear. This configuration aims to provide a comfortable ride and stable handling. Stabilizer bars are included both front and rear to minimize body roll during cornering. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) is standard. The vehicle’s relatively high curb weight of 2300 kg (5070.63 lbs) necessitates a robust suspension and braking system.
Market Reception & Comparison
The Li ONE was generally well-received in the Chinese market, lauded for its spacious interior, long range, and advanced technology. Critics praised the vehicle’s comfortable ride and quiet operation. Fuel economy, while improved over traditional gasoline SUVs, was a topic of discussion, with combined consumption rated at 8.8 l/100 km (26.7 US mpg). Compared to other plug-in hybrid SUVs available in China at the time, the Li ONE distinguished itself with its larger battery capacity and focus on extended-range capability. Its unique series hybrid architecture also set it apart from competitors that employed parallel hybrid systems.
Legacy
The Li ONE played a pivotal role in establishing Li Auto as a significant contender in the Chinese NEV market. While production concluded in May 2021, the model’s success paved the way for Li Auto’s subsequent offerings. The powertrain, despite its complexity, proved to be relatively reliable in real-world use. On the used car market, the Li ONE continues to maintain its value, appealing to buyers seeking a spacious, technologically advanced, and relatively long-range electric SUV. The vehicle’s innovative approach to range extension helped to popularize the concept of extended-range electric vehicles in China, influencing the development of subsequent models from other manufacturers.
