The Porsche Boxster has been a fantastic entry-level sports car for many years and with the introduction of the S-line continues to set the benchmark in its class. Today the German car maker presents the 2015 Porsche Boxster GTS and Cayman GTS to ensure its lead. The 3.4 liter engine comes with 15 more horsepower than before, with the total now being at 340 hp. The car sprints from 0-100 km/h in just 4.6 seconds. The headlights and interior have also been updated in order to distinguish the pair from the regular S-line. The Porsche Boxster GTS will go for €69,949 and the Cayman GTS will go for €73,757, with prices in the U.S. of course being as usual considerably cheaper.
