Porsche has brought out a brand new generation of its entry-level Boxster convertible, one that’s lighter, more powerful, and more fuel-efficient than the model it replaces.

It’s also a whole lot sexier too, thanks to a design incorporating shorter overhangs, a wider track, and square-shaped headlights inspired by the units on the upcoming 918 Spyder hybrid supercar.

The comprehensive changes to the Boxster line--and a new 2013 Cayman--were possible due to a brand new platform, which in addition to being lighter is slightly bigger than the previous one too.

These new dimensions are coupled with larger, 20-inch wheels and a new electromechanical power steering system to significantly enhance the mid-engine sports car's handling and dynamics. The suspension still features MacPherson struts up front and a multilink setup in the rear.

Once again both a Boxster and sportier Boxster S will be available. Both are powered by flat-six engines with direct fuel injection, the efficiency of which is further enhanced by electrical system recuperation, thermal management and an engine start-stop function. Porsche promises the cars are roughly 15 percent more fuel-efficient than previous models. Final EPA figures will be released closer to launch.

The engine in the new Boxster displaces 2.7 liters and develops a peak output of 265 horsepower, 10 more than in the previous one despite a smaller displacement. Customers will be able to choose from either a six-speed manual or seven-speed PDK dual clutch, the latter allowing the Boxster to sprint from 0-60 mph in 5.4 seconds.

Opt for the Boxster S and in addition to a host of other upgrades you also get a more powerful 3.4-liter engine with 315 horsepower on tap. The 0-60 run in this model will take you just 4.7 seconds, also with the PDK.

To enhance driving dynamics yet further, Porsche offers the Sport Chrono Package as an optional extra, featuring dynamic transmission mounts for the first time. Also new in the Boxster is Porsche Torque Vectoring (PTV) with a mechanical rear axle differential lock that varies the level of torque sent to each of the rear wheels.

Taking a look at the interior, we can see that designers have been inspired by the new look found in the 2012 911, which itself has been borrowed from the Panamera and Cayenne. The cabin is enclosed by a fully electric top and Porsche claims that there’s more space all ‘round for the driver and passenger.

The 2013 Porsche Boxster will hit showrooms just in time for summer with a starting price of $49,500 for the base model and $60,900 for the more capable Boxster S. Note, both prices are exclusive of a $950 destination charge.
