Hadn't it been for the 1.0L limit for lower taxes, maybe that approach could be tried with the 1.3L version of that engine series in order to do so while retaining some acceptable performance on gasoline despite the decrease on volumetric efficiency while running a longer intake valve phasing overlapping the compression stroke, in a similar way to what Toyota did with the 8AR-FTS currently fitted to the Lexus IS and NX despite it not featuring "flexfuel" ability on them.
Sure the technical mediocrity has led to the lack of confidence on "flexfuel" vehicles as an approach to improve the marketing perspectives for ethanol, but the advances on engine design now available could overcome that issue. Countries such as Brazil where a higher tax bracket is enforced for bigger engines also have a political challenge in case the interest to take ethanol seriously becomes real, but the cards are on the desk. It's now basically a matter of which configuration to choose, but it's effectively possible to overcome the mediocrity and make "flexfuel" cars really desirable...

Gurgel BR-800, the Brazilian subcompact that nearly became an effective replacement for the Volkswagen Beetle
With the first production-ready prototypes featured in Brasília during the Independence Day Military Parade in september 7th, 1987, and the deliveries starting in the following year, the Gurgel BR-800 was not so much of a commercial success but had some technical features that rendered it effective as a viable replacement for the Beetle. Despite having a front-mounted engine while retaining the rear-wheel drive, which called for a presumably less-efficient transmission setup due to the presence of a driveshaft, the 50-50 unloaded weight bias meant any compromise to the the cross-country capability would be minimal. Relying on the same 4-speed manual transmission and rear axle found in the 1.4L versions of the Chevette, the Gurgel-designed 0.8L water-cooled OHV flat-twin was meant to reach the then-impressive 25km/l (around 62MPG) fuel consumption. Overall performance was not really something to brag about, but neither were some comparable European-designed cars that were never brought to Brazil by the local branches of foreign automakers such as Fiat. Featurng a space-frame chassis with a fiberglass-reinforced plastic body, its manufacturing was somewhat labor-intensive and time-consuming in a comparison to the pressed-steel unibody layout which was already widespread among major automakers.
Marketing was not so great, with the sales between 1988 and 1990 being tied to stockholding of the company and therefore it became a less attractive option for those buyers who were just looking for a no-frills car and nothing else. The situation became worse for Gurgel in 1990 when Fiat applied for a fiscal incentive for cars up to 1.0L instead of 0.8L and the Fiat Uno Mille could be offered at a more competitive price due to the greater production scale inherent to its design. As a former director of the local branch of Mercedes-Benz once said, Brazilian people consider the size of a car as one of the most relevant matters comparing different models close in price, so the 3.195-metre long and 1.47-metre wide BR-800 was in a clear disadvantage against the Fiat Uno, being phased out in 1991 with a technically-similar model named Supermini replacing it from 1992 to 1994 when Gurgel went out of business. However, nowadays with a new generation of small city-cars flourishing even in Brazil, it's worth to remind the Gurgel BR-800 and the attempt to effectively replace the Volkswagen Beetle.
