Chevrolet Onix Returns To Reduced Power In The 1.0 Turbo Engine, Now Delivering 115 Hp. The Reason For The Change And Its Impact On The Consumer.

The Chevrolet Onix has undergone a new change in its 1.0 turbo engine. After reaching 121 hp with the adoption of direct injection, the model now returns to delivering 115 hp.

The reduction in power is directly related to tax incentives for cars considered sustainable and is not the result of failure or regression in engineering. Understand the details behind this decision and its impact on the market.

New Power Of The Onix Surprises Consumers

The Chevrolet Onix, one of the best-selling vehicles in Brazil, has undergone a significant change in its engine.

Now, the 1.0 turbo model delivers 115 horsepower, a reduction from the 121 hp recently announced. This change has raised eyebrows among some consumers, but it has a clear reason.

Why Did The Onix Lose Power Again?

The drop in engine power is not related to design flaws or technical setbacks. Chevrolet made this change to meet the criteria established by the federal government to classify the model as a sustainable car, which ensures total exemption from IPI (Tax on Industrialized Products).

Changes To Meet Sustainability Goals

In 2023, the government launched new guidelines to encourage the production of cleaner and more efficient vehicles.

To fit into this category, the car needs to meet a series of consumption and emission requirements.

Thus, to guarantee this sustainability seal, Chevrolet recalibrated the 1.0 turbo engine, reducing its power to 115 hp.

Recall The Evolution Of Power In The Onix

Interestingly, this is not the first change in performance for the Onix. Before the adoption of direct injection, the turbo engine generated 116 hp.

With the update carried out at the end of 2023 to meet Proconve L8 (Air Pollution Control Program for Motor Vehicles), power reached 121 hp.

Now, for fiscal and strategic reasons, performance has been adjusted downward again.

Zero IPI And Reduction In Final Price

With the new configuration, the Onix is now benefiting from zero IPI, which can represent a significant reduction in the final price to the consumer.

The strategy aims to make the car even more competitive in the market and maintain its sales leadership.

What Changes For The Driver?

In practice, the power difference of 6 hp is hardly noticeable for most drivers. The torque remains high for the category, ensuring good acceleration and satisfactory performance in both cities and roads. Furthermore, fuel economy is expected to improve slightly.

In practice, the driver is unlikely to notice a difference in the Onix’s performance on a day-to-day basis. The reduction of 6 horsepower is compensated by electronic adjustments that maintain agile and economical handling.

Market Remains Attentive To The Power Of The Onix

The Onix remains one of the most sought-after models in the country, and even with the new power reduction, the model is expected to maintain its relevance.

Chevrolet’s strategy reinforces its focus on efficiency, economy, and fiscal competitiveness, keeping up with trends in the Brazilian market.

This change is part of the adaptation to the IPI exemption regime for sustainable vehicles. The engine update aims to meet the technical criteria required by the government program.
