After months of teasing, Volkswagen has officially unveiled the 2012 Beetle at the Shanghai Auto Show.  Drawing inspiration from the Ragster concept, the redesigned model drops the girlish looks for a sportier appearance that is "bolder, more dynamic, and more masculine."

Immediately, rumors about the car's future potential have begun swirling around. Car and Driver is reporting on an unnamed source's confirmation that Volkswagen will offer a Beetle R. Nothing is official, but the magazine speculates the model could use a turbocharged 2.0-liter engine that develops 270 PS (199 kW / 266 hp) and 350 Nm (258 lb-ft) of torque.

A VW rep also reportedly told the magazine that a drop-top version of the Beetle is due in 2012. Expected as a 2013 model year car, we would not be surprised to see a convertible to come out before the summer.

Inside, the hard top's cabin is vastly improved as material quality finally joins the 21st century. Furthermore, there's more legroom and the boot can hold up to 310 liters (11 cu ft) of luggage. If that isn't impressive enough, options include passive entry, a panoramic sunroof, a Fender audio system, and GPS navigation.

Under the hood, a variety of engines will be offered. In North America, choices include a 2.5-liter five cylinder petrol with 170 PS (125 kW / 168 hp) and 200 PS (147 kW / 197 hp) as well as a 2.0-liter TDI that produces 140 PS (103 kW / 138 hp).

In Europe, petrol choices consist of a 1.2-liter TSI BlueMotion with 105 PS (77 kW / 104 hp), a 1.4-liter TSI with 160 PS (118 kW / 158 hp) and a 2.0-liter TSI that produces 200 PS (147 kW / 197 hp). On the other hand, diesel options include a 1.6-liter TDI with 105 PS (77 kW / 104 hp) and a 2.0-liter TDI that churns out 140 PS (103 kW / 138 hp).
