2013 Porsche Boxster Fuel Economy Rated by EPA

The Environmental Protection Agency has released fuel economy estimates for the base 2013 Porsche Boxster. The newly redesigned luxury sports car is fitted with an all-new 2.7-liter flat-six engine that produces 265 horsepower, which is an increase of 10 horsepower over the 2012 model. When matched to a six-speed manual transmission, the EPA estimates the Boxster is capable of reaching 20/30 mpg city/highway. It should earn 22/32 mpg with the optional seven-speed dual-clutch automatic.

Not only is the redesigned Boxster 10-horsepower stronger, its fuel economy estimates are better than those of the outgoing 2012 model. According to the EPA, a 2012 Boxster with a seven-speed dual-clutch automatic is good for up to 20/29 mpg city/highway, while six-speed manual-equipped models get 19/27 mpg.

Changes to the Boxster for 2013 are more extensive than a new engine. Motor Trend reports, “Despite having a 2.4-inch longer wheel-base and 1.6-inch wider front track, the 2013 Boxster, which rides on a chassis derived from the 991 911, is about 55 lbs lighter.”

The new Boxster stacks up well against some of its key rivals. The 2012 Audi TTS Roadster has a turbocharged four-cylinder engine that also produces 265 horsepower and gets an EPA-estimated 23/31 mpg city/highway. The 2012 BMW Z4 sDrive28i also has a turbocharged four-cylinder engine, though at 240 horsepower, it is a bit less powerful than the Boxster and TTS. With an eight-speed automatic, the Z4 gets an EPA-rated 24/33 mpg city/highway, while the six-speed manual model achieves 23/34 mpg.

Fuel economy estimates for the 315-horsepower 2013 Boxster S have yet to be announced. The 2013 Boxster starts at $49,500, not including a $950 destination fee.
