Even though you have more chances to spot a prototype model of a future Porsche model doing the rounds at the Nürburgring racetrack than anywhere else, the Germans try out their cars in many countries around the world, including of course, the U.S.

Carscoop reader Alex Ranarivelo snapped this lightly camouflaged 2013 Porsche Boxster with Michigan license plates rolling around in Los Angeles.

Understandably, he was only able to take a quick picture of the two-seater roadster model from behind – though judging from Porsche’s past and previous spy shots, don’t expect any revolutionary changes to the Boxster’s design.

But while the styling of the Mk3 Boxster may not raise any eyebrows, the possibility of a new four-cylinder engine will surely come as a surprise.

Official details remain slim, but there’s an increasing number of reports suggesting that Porsche is currently developing a horizontally opposed four-cylinder unit with turbocharging and direct injection technologies that will be available with a displacement of 2.0-liters or less.

If it turns out to be true, the same engine will also be offered on the replacement of the Cayman coupe.

Kudos to Alex for the scoop!
