Next-generation Porsche Boxster and 911 models testing side by side also share some design details.
Here's a set of spy shots of the upcoming 2012 Porsche Boxster doing some winter testing in northern Sweden next to the next-generation Porsche 911.
The next-generation Boxster, known internally at Porsche as the 981, was rather showy on this test run, revealing its new LED taillights - a triangular design like on the next 911.
The next Boxster may come with a new four-cylinder engine that Porsche is developing, as we reported earlier this week. Porsche's outgoing head of research and development, Wolfgang Durheimer, confirmed that the automaker was developing a 2.5 liter power plant that could possible be seen in the 2012 Boxster and Cayman models.
That 2.5 liter could have an output of up to 360 bhp (268 kW / 365 PS) in a turbocharged configuration.
