Porsche rolled out a lighter, more powerful 2013 Boxster at the Geneva Motor Show this week, which also promises better fuel economy than the outgoing model.

Autoblog says, “The standard car is powered by a direct-injected 2.7-liter flat-six with 265 horsepower, while the Boxster S uses a DI [direct injection] 3.4-liter flat-six with 315 horsepower – gains of 10 and five horses versus the 2012 models, respectively.” A six-speed manual transmission is standard, while a start-stop feature has been added to help conserve fuel.

A seven-speed PDK automated-manual transmission is optional on both models. Porsche says in a press release that the best acceleration and fuel economy is achieved with the PDK, noting that “the Boxster sprints from zero to 60 mph in 5.4 seconds, the Boxster S in 4.7 seconds.” EPA ratings on the new luxury sports car are pending, but the automaker says that in European tests the new Boxster is up to 15 percent more fuel-efficient.

The 2013 Boxster also sports new styling, with a body that’s longer and wider than the outgoing model. “That should make the Boxster more comfortable and increase performance at the same time,” writes Automobile Magazine. “The 60-pound weight loss will also help performance across the board.”

Porsche says that the new Boxster and Boxster S will hit showroom floors in summer 2012 with base prices of $49,500 and $60,900, respectively. Automobile Magazine notes that if you prefer a hardtop, “the new Cayman will debut before the end of the year.”
