Volkswagen's set to show off for its home crowds at next month's Frankfurt auto show with its new Eos hardtop convertible and a twin-turbo FSI engine that will find its way into a special edition of the Golf. The Eos, which is the production version of the Concept C roadster, is named for the goddess of the dawn, VW says. Developed separately from any of VW's other models, the Eos will be offered with a range of engines with power output of 113 hp to 247 hp.

The new twin-turbo FSI engine will be displayed under its simpler "Twincharger" name. The Twincharger engine uses a small 1.4-liter four-cylinder engine combined with its direct-injection system and twin turbochargers to develop the power of a larger-displacement engine - 168 hp, it's estimated. The strong torque at low speeds, VW says, is complemented by fuel economy of about 39 mpg. VW plans to team up the engine with its DSG gearbox to propel the new Golf GT model to 60 mph in 7.9 seconds and to a top speed of 136 mph.
