Fiat 126, as the smallest car in the Fiat range. But the real breakthrough in small car design was the 1993 Renault Twingo which was a revolution in styling by being the first 'one box' small car to reach production. The early pre-production Citroën AX supermini launched in 1987 was a 'monobox' design, but the production version was much more conservative after negative reactions in focus groups. Both had the interior space of a much larger car. The Twingo and Cinquecento relaunched the city car market in Europe - for decades the only competitors in this market were the Austin Mini and the Polish built Fiat 126 (developed from the 1950s Fiat 500). Economy cars since 2000 Today economy cars have specialised into market niches. The small city car, the inexpensive-to-run but not necessarily very small general economy car, and the performance derivatives that capitalise on light weight of the cars on which they are based. Some models that started as economy cars such as the Volkswagen Golf and Toyota Corolla, have increased in size and moved upmarket over several generations, and their makers have added smaller new models in their original market niches. The 2003 Volkswagen Golf Mk5 had put on so much weight, that some models weigh the same as a Volvo 200 Series. The supermini 2002 Volkswagen Polo Mk4 was longer and wider than the 1970s Volkswagen Golf Mk1. Gordon Murray the Formula 1 and Mclaren F1 designer, said when designing his new Murray T.25 city car: "Today with all the promises of hydrogen and hybrids and electric cars, if you could take ten percent out of the weight of every car, the effect in the next ten years would be more than that of all the hybrids and electric cars on the planet." The City car market in Europe from the 1990s has seen increased competition, with the market split between standard and 'designer' city cars that are sold for a premium. These cars are at the lower end of supermini size or smaller. Standard city cars include the Toyota Yaris, Citroën C1/Peugeot 107/Toyota Aygo (built in the same factory), Fiat Panda, Kia Picanto, Chevrolet Matiz, Volkswagen Fox, Mitsubishi Colt, Volkswagen Lupo, and 2011 Volkswagen Up. The 'designer' city car became increasingly popular in Europe in the 1990s. The first car of this kind was a limited success, the 1985 Lancia Y10, because it had been
