We first saw the Volkswagen UP! at the Frankfurt Auto Show four years ago. The Germans have brought their little car back for its production debut today at the 64th edition of the premier German auto event. Six concepts are present in the new range, including the Buggy Up, Cross Up, GT Up, E-Up, Eco Up and Up Azzurra. As we have previously reported, the Up! is built off of VW's new MQB platform, which is a modular structure that will be used to also underpin the next generation Polo, Golf, and the Euro-spec Passat.

The six concepts are meant to show how versatile the platform truly is. Power will solely come from an eco-minded turbocharged 1.0-liter TSI three-cylinder gasoline engine, however, it will have two tuning options. The base model has 59hp that will supposedly return 56 mpg (combined European cycle) and a sportier version will have 74hp and is rated at 54.6 mpg. Each model is a bit unique and can fit almost any need. The Buggy Up was built as a tribute to 1960s style VW Beetles. It features a convertible roof and a pickup style trunk.

The E-Up is the fully electric model that will arrive in 2013 and have a range of 80 miles. The Up Azzurra has a Mediterranean style design. The Eco Up is powered by Compressed Natural Gas and gasoline. The Cross Up will most certainly hit production, as a rugged four-door subcompact with fog lights. The GT Up copies the Golf GTI and packs 98hp. VW believes that it is the first minicar able to handle the Autobahn. As of now, Volkswagen doesn't have any plans to import the new subcompacts to North America.
