New version of the Chevrolet Onix 2027 combines exclusive turbo engine for ethanol, six-speed automatic transmission, and promotional price below R$ 100,000, a strategy that takes advantage of tax incentives, discreetly improves performance, and broadens appeal among consumers and large fleets.
Chevrolet expanded the 2027 Onix line with the Eco version, equipped with a 1.0 turbo engine calibrated exclusively for ethanol and a six-speed automatic transmission, initially offered for R$ 99,990 in the hatch body.
With this promotional price, the compact assumed the position of the cheapest brand-new automatic car in the Brazilian market, even below the Onix 1.0 manual, priced at R$ 102,890 within the same 2027 line range.
In the sedan body, the Eco configuration arrived for R$ 103,990 during the campaign, while the prices without bonus were set at R$ 103,190 for the hatch and R$ 106,990 for the Onix Plus of the 2027 line.

Hilux’s little sister: Toyota relaunches the Land Cruiser 70 in the 2027 lineup with over 40 years of production, a 2.8 turbo diesel engine with 201 hp and 51 kgfm, a six-speed automatic transmission, and a renewed retro look.

Automatic, economical, and known for reliability: with a 1.5 engine of up to 110 hp, CVT transmission, seven airbags, and fuel consumption of up to 15.9 km/l, this used hatchback appears as a rational alternative to Polo, HB20, and Onix; meet the Toyota Yaris XLS 2020.

He surpassed the Tera, Creta, and Tracker: With a TSI engine of up to 150 hp, 6-speed automatic transmission, and a 373-liter trunk, the Volkswagen T-Cross was the best-selling SUV in June, with 11,753 registrations.

It looks factory-made, but it came out of a workshop: a mechanic from Pernambuco builds a handcrafted “mini Toyota,” drives it through the streets, and the video goes viral on social media, leaving residents astonished.
In the offers disclosed by the brand, the Onix Plus Eco appears with a 100% ethanol engine, six-speed automatic transmission, and an initial promotional price of R$ 103,990, while the hatch maintains the condition of R$ 99,990.
Tax incentive favors the ethanol-powered Onix
Behind the change is the alignment with the Sustainable Car Program, linked to Mover, a federal policy that uses environmental efficiency criteria to define the taxation applied to cars produced and sold in the Brazilian market.
In this evaluation, emissions follow the “well-to-wheel” concept, which considers different stages of the energy cycle, from fuel production to its use by the vehicle, instead of only observing the gases released by the exhaust.
The aspirated and manual versions of the Onix already achieved the maximum benefit due to lower weight and reduced consumption, but the 1.0 turbo automatic set could not achieve the same alignment while it remained prepared for gasoline and ethanol.
After the gasoline calibration was removed, Chevrolet reduced the tax burden of the new version, making the list price of the Eco hatch about 7.8% below the equivalent flex automatic Onix, sold for R$ 111,990.
1.0 Turbo Engine Maintains 115 hp and 16.8 kgfm
Although it runs only on ethanol, the engine did not receive significant physical changes in compression ratio, turbine, or main internal components, because the development focused on electronic calibration and ignition and combustion parameters.
Even with the fuel change, the power remained at 115 hp and the maximum torque continued at 16.8 kgfm, while the six-speed automatic transmission was adjusted to work exclusively with the characteristics of the vegetable fuel.
Without needing to manage two fuels with different properties, the electronic control unit began using specific parameters for ethanol, which brought small gains in efficiency and performance, despite maximum power and torque remaining unchanged.
In the Onix Plus Eco, the reported consumption is 9.1 km/l in urban cycle and 11.1 km/l on the highway, a result that represents an advance of 0.2 km/l on the road compared to the corresponding flex configuration.
Performance Improves with Exclusive Calibration for Ethanol
There was also a slight improvement in acceleration, as the model went from zero to 100 km/h in 10.5 seconds, one-tenth faster, while the recovery from 80 to 120 km/h dropped to 8.3 seconds exactly.
These gains remain limited because the manufacturer preserved the engine’s mechanical structure and prioritized a software adaptation capable of meeting incentive criteria without significantly increasing development costs.
Besides the common consumer, the configuration was aimed at direct sales and companies with large fleets, offering an alternative with lower fossil carbon emissions without requiring the recharging infrastructure needed for fully electric vehicles.
For companies monitoring environmental indicators, the proposal allows reducing emissions associated with corporate transportation without abandoning conventional refueling, while still maintaining a lower acquisition cost than found in many electrified vehicles.
Lower Price Requires Exclusive Ethanol Refueling
On the other hand, the Onix Eco cannot be refueled with gasoline, a condition that requires the buyer to consider the availability and price of ethanol in their region, factors that can alter the final cost per kilometer.
Even so, the initial discount makes the automatic version cheaper than the entry-level manual Onix itself and widens the gap compared to the automatic flex turbo Onix, priced at R$ 111,990 before any regional promotions.
With this, Chevrolet revives a solution practically abandoned after the popularization of flex engines, but now based on tax rules, environmental goals, price reduction, and electronic calibration dedicated exclusively to ethanol fuel.
For the consumer, does the decision now depend on the balance between the promotional price below R$ 100,000, the regional availability of ethanol, and the loss of freedom to choose gasoline at the time of refueling?
