With An Engine That Acts Only As A Generator And A Thermal Efficiency Of 42%, Nissan Aims To Regain Its Lead In The Hybrid Race

Nissan Launched The Most Efficient Hybrid Engine In The World. The Nissan E-Power of the third generation was detailed with a new three-cylinder engine dedicated exclusively to functioning as an electric generator.

The system was introduced with a focus on efficiency, with a thermal rate of 42%, exceeding the 41% announced by direct competitors in the segment.

The first vehicle in the world to adopt this new e-POWER system is the Qashqai, whose production began in July at Nissan’s advanced plant in Sunderland, United Kingdom.

Nissan E-Power Of The Third Generation: Architecture And Efficiency

In the technical arrangement, the 1.5-liter engine, ZR15DDTe, does not drive the wheels. Propulsion is provided by an electric motor, while the combustion unit operates as a generator.

The declared higher thermal efficiency indicates better conversion of the fuel into electricity, with reduced losses and gains in range without an increase in consumption.

The Nissan E-Power was announced as a response to the competition with Toyota and Hyundai.

The declared objective is to surpass the current efficiency parameters among conventional hybrids of high volume, while maintaining a simplified architecture for operation and maintenance.

Cold Spray Manufacturing And Patent

The advancement was attributed to a novel method of applying valve seats via cold spray directly onto the cylinder head, replacing traditional pressing.

The process projects copper-based metal powder at supersonic speeds, adhering precisely to the surface outlined in the design.

This procedure enables an optimized intake port design, with reduced turbulence and improved flow to the combustion chamber.

The reported result includes more stable and efficient combustion. The alloy with high thermal conductivity contributes to the cooling of the valves and the durability of the assembly.

Nissan announced it obtained the patent for the system in April 2025, after filing in 2020.

This indicates a competitive advantage in manufacturing processes that directly impact the performance of the generator engine.

Lessons From The VC-Turbo And Launch Strategy

The announcement follows previous questions about the brand’s engine innovations.

The VC-Turbo, with variable compression, was labeled a failure due to mechanical complexity and reliability issues, with mass recalls.

The new solution arises from the simplification of an existing component to mitigate risks and ensure effective efficiency gains without project overload.

The debut in North America is confirmed for 2027, alongside the fourth generation of the Nissan Rogue, known as X-Trail in other markets.

The Nissan E-Power of The Third Generation is part of the corporate restructuring plan that uses hybrids as an intermediate step towards full electrification.

Competition And Technological Goals

The 42% thermal efficiency remains below the 50% achieved by hybrid engines in Formula 1, enabled by electric supercharging.

Still, the figure was characterized as an advancement for high-volume applications.

The strategy seeks to reposition the brand at the forefront of accessible hybridization in light of Toyota’s historical leadership and Hyundai’s recent advances.

The Nissan E-Power of The Third Generation is presented as the core of global repositioning.

If the predicted deliveries are confirmed, the brand could regain its technological prominence that was considered diminished over the past decade. The system’s evolution will be observed from the scheduled launch.

1 – Cold spraying is a coating technology in which powder materials are sprayed at supersonic speeds to form a solid layer. Since the 2000s, it has been widely adopted in the aerospace, energy, heavy equipment, oil and gas industries, and other manufacturing sectors, providing advantages in terms of reliability and quality. Recently, it has gained attention for its applications beyond surface treatment, including additive manufacturing.

2 – STARC (Strong Tumble & Appropriately Stretched Robust Ignition Channel) is a combustion concept announced by Nissan in 2021, which provides impressive thermal efficiency.

3 – A sintered valve seat is a type of valve seat used in internal combustion engines, made through a process called sintering. Sintering involves compressing powder materials — typically metal powders — under heat and pressure to form a solid, durable component without melting the material completely.

Competition And Technological Goals

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Ethiopia has banned gasoline and diesel cars, placed over a hundred silent electric buses on the streets of Addis Ababa, and now aims for half a million electric vehicles by 2030, all powered by Africa’s largest dam and a courage that few countries have shown.

Egypt wants to draw 10 million cubic meters of water from the Nile per day into the desert, irrigate a new agricultural frontier, and build a city where there is currently only sand.

Norway is drilling 27 kilometers of rock 392 meters below the bottom of a fjord to build the world’s largest and deepest underwater road tunnel — when completed, a 21-hour journey will be reduced to 10.

An astronaut spent 340 days in space while his twin brother stayed on Earth, and NASA found a “rejuvenating” effect, genes, microbiome, cognition, and immune system that revealed the biological cost of living outside the planet.

Chinese engineers begin filling a 217-meter dam at an altitude of 3,000 meters and prepare a 2,240 MW hydroelectric power plant to integrate hydropower, solar, and wind energy in the upper Jinsha.

A United States soldier who was on the mission to capture Nicolás Maduro bet hours before the official announcement, profited over US$400,000 on a prediction platform, and now faces federal charges.

More than 100 scientists warn that India, China, the United States, Mediterranean countries, and parts of Africa could enter an era of persistent droughts by the end of the century, with rivers under stress, demand exceeding supply, and a growing risk of continuous water scarcity.

Engineers from Iceland descended 4,659 meters into an active volcanic zone, and the IDDP-2 project found supercritical fluids at 427 degrees and 340 bar of pressure, crossing the boundary where water ceases to be liquid or vapor and begins to concentrate energy at extreme levels.

The biggest climatic tragedy ever recorded in the South of Brazil buried a family winery in mud, destroying machinery and production, but the family managed to transform the multi-million dollar loss into a new beginning with a limited edition of wines rescued from the disaster.

It costs R$ 80,000 today, but was once worth R$ 900,000: the “rich man’s cast-off car” attracts with its luxury, but conceals high-standard maintenance that can turn into a loss.

Chinese automaker launches the Avatr 06T electric wagon with 955 hp, up to 1,250 km of range, and a three-motor system, betting on a version with a range-extending turbo generator to extend long journeys and compete in the premium EV segment.

When it seemed that combustion was doomed, industry giants came together and created a gasoline engine that promises to achieve more than 3 liters per 100 km and rekindles the hope of those who want to drive further while spending much less fuel.
