Driving Entirely On Ethanol: Volkswagen Gol Flex-Fuel Vehicle

it like to drive on pure known as E100, without a of gasoline in the car?

In the case of the Volkswagen Gol, it’s unremarkable.

Brazil’s most small car for 27 years starts, and otherwise behaves just a gasoline-fueled car—except that burning pure ethanol from sugar cane.

from 2003

VW was the first to offer vehicles with capability in Brazil, starting in 2003. Now, every it builds in Brazil comes with the ability to burn (E100), the gasoline-ethanol blend as “petrol”—which contains 78 percent and 22 percent ethanol—or any mix of the two.

That Volkswagen’s highest-volume models in can use either fuel or both. include the Gol (not Golf!) family, the slightly smaller the Brazilian version of the Up minicar, and the new compact, all assembled in Brazil and by engines built in the country.

more expensive VW models (or engines) imported from in other countries lack the feature, including the Jetta, and Passat.

The country did raise the proportion of in its standard gasoline, however. Its 22 percent ethanol blend (it varies from 20 to 24 percent on the sugar crop each uses more than as much of the biofuel as U.S. which is universally up to E10 and which the EPA is to raise to E15.

Brazilian refining, however, produces as fuel from an acre of cane (about 600 gallons) as production does from an of corn (about 300 gallons).

is viewed as a carbon-neutral fuel, the feedstock—whether corn, sugar or any other plant—absorbs carbon from the air, offsetting the emitted during combustion.

The Gol (it means “goal” in Portugeese), U.S. buyers would a subcompact, is a five-door hatchback.

Two body styles share its and engine options: The Voyage is a sedan, and the Saveiro is a small truck, offered in standard or versions.

We drove a Gol Rallye—a high-end trim level—and a Cross, the pickup truck extended cab that also a higher ride height, fender lips, plastic cladding, and other tough stylistic touches. It doesn’t all-wheel drive, but the look is nonetheless.

Both of our test had the more powerful of the two engines in the Gol family, a 1.6-liter fuel-injected that produces 102 horsepower (76 kW) on and 99 hp (74 kW) on gasoline. It is part of Volkswagen’s engine family.

The other engine offered in the Gol which we did not test-drive, is the same three-cylinder used in the Volkswagen Up we tested—but adapted for Brazilian

Known in Brazil as the TEC para Economia de combustível), it 75 hp (56 kW) on ethanol and 71 hp (53 kW) on gasoline.

Each comes standard with a manual gearbox driving the wheels. An automatic sequential or dual-clutch transmission, which we did not is an option on the larger engine. A package that includes tires and a shift-reminder light can fuel economy up to 8 percent.

Both fitted to the Gol come standard what Volkswagen calls technology, which includes and plastic components hardened to deterioration from the pure fuel, and—as of 2012—a new way of ethanol’s reluctance to start in cold weather.

When Volkswagen launched the flex-fuel Gol in 2003, it a very small ancillary tank—just 0.7 liters, or less one-fifth of a gallon. In very temperatures, if the main fuel contained ethanol, the engine start itself on gasoline switching over to the ethanol. who adapt older diesel to burn recycled fryer do the same thing, using a tank of conventional diesel for cold starts.)

This was a way of getting around notoriously hard cold-starting before the engine and fuel warmed up.

The challenge was that would sometimes forget to the tiny gasoline tank—and if ran out altogether, they would be when their car became to start during cold months.

Now VW has been able to that ancillary gasoline by building a heating element into the fuel-injection rail. In weather, as soon as the driver’s opens, the car uses battery to heat up the element even the driver sits down, the seat belt, and turns the Owners of the new models hear a slight humming sound.

On the road, the versions of the Gol and Saviero drive like any gasoline car. shouldn’t be a surprise, but it will Brazilians who remember the country’s round of all-ethanol cars the 1980s—which were notoriously and sometimes temperamental. The current Gol can what fuel is coming the engine and adjust its combustion accordingly.

It takes the car 2 or 3 seconds after a to adjust itself, VW executives but while the engine may not be operating at power or efficiency during short period, drivers won’t notice any difference.

Calculating best for money

The flex-fuel capability owner the chance select two fuels every time fuel up. But the calculations require thought.

When we visited Sao gasoline cost about 3 per liter ($5.15 per gallon) and cost 2.2 to 2.3 reals ($3.75 to per gallon).

But the ethanol only 70% of the miles of E22 gasoline—at least the rule of thumb Brazilians its energy content is lower.

So can you do the in your head to work out fuel gives you more for your money?

Brazilian drivers can, and time they fill up.

answer is that ethanol have to be as low as $3.60 a gallon to the miles delivered by gasoline—so weekend, gasoline was a slightly value.)

Ethanol fueling varies across the country, the highest number of ethanol in the states around Sao Paulo, to where fuel is refined locally grown sugar

It’s important to note Volkswagen is far from the only selling flex-fuel cars in Fiat, Renault, and others, the feature on a variety of small, hatchback, sedan, and pickup as well.
