STUTTGART, Germany - A sleeker Porsche Cayman will roll into German showrooms from early March as the automaker breathes on the second-generation model with its even-tauter stance.The mid-engined Cayman is the third sports car in the brand's line-up alongside the iconic 911 and evergreen Boxster. It's lighter and has an upgraded interior, just like those of other Porsche models which usually cost twice as much as a Cayman.There are two six-cylinder engines (2.7 or 3.4 with 205kW and 242 Kw respectively). Each is available with either a six-speed manual gearbox or a seven-speed dual-clutch auto with steering-wheel paddles for manual/sequential operation. Top speed is 280km/h with, it's claimed, lower fuel consumption. The sport models have all been under the knife so now Porsche is focusing on its four-doors.AND THAT'S NOT ALL...The upcoming 2013 Shanghai auto show in April and the Macan off-roader show later in the year will see the debut of the fresh new four-door GT Panamera. The off-roader is based on the chunky Audi Q5.2013 is off to a good start for Porsche with more exciting models headed for the limelight : the comeback of the 911 Targa with its detachable amidships roof and the ultra-sport 918 Spyder.
