Renault has thankfully brought more to the Sao Paulo Auto Show than just an F1 edition of its inexpensive Dacia Sandero with racy decals and a bodykit. The other car in its display is another Sandero, but this one is much cooler. Called the Sandero Sand'up concept, it's a 2+2 beach runabout that can go from a closed hard-top coupe to a convertible pickup thanks to its modular design. While not the freshest idea to appear on a concept, the Sand'up is charming enough with its big wheel arches, satin nickel roof rail arches and see-through doors. The first concept by Renault to be designed entirely in South America, the Sand'up is not surprisingly powered by a 1.6L Hi-Flex engine that produces 107 hp on gasoline and 112 hp on ethanol, the latter of which is a more popular fuel below the equator than above at the moment.
