I've spotted this Gurgel Supermini BR-SL about 2 weeks ago in Pelotas, a city about 190 miles from my hometown.
It was made from '92 to '95 when Gurgel Motor Co. went bankrupt, fitted with a water-cooled flat-twin 0.8L engine, carburettor-fed, with 35hp, backed by a 4-speed manual transmission, with rear-wheel drive thru a solid axle. The body is made out of fiberglass, with a steel space-frame, like the Chevrolet Lumina APV. It weights less than 1500lbs and the mileage is similar to a Prius.
