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.
