An international jury of 87 highly regarded automotive journalists has heralded Porsche’s flat-six engine that powers the Boxster and the Cayman as the “Engine of the Year” for the 2.5 to 3.0-liter engine displacement class. The engine’s ability to bring out power while saving fuel is what prompted the jury to hand the award to it.
Dean Slavnich of “Engine Technology International Magazine” described the powerplant as “a brilliant engine for a brilliant car.” He remarked that the engine combines “performance and a sporty pedigree with impressive fuel efficiency.”
The jury likewise acknowledged the flat engine’s flexibility and responsiveness as well as performance and smooth running. The flat engine was derived from the 3.4-liter engine based on the downsizing principle.
Porsche paired the engine with the PDK (Porsche Doppelkupplung) transmission in the Cayman, providing up to 275 hp (202 kW) of power. It also boasts of NEDC fuel consumption of 7.7 liters/100 km and carbon dioxide emission of 180 g/km.
The six-cylinder engine’s specific power of 101.6 hp/liter means that it exceeds the magic limit of 100 hp per liter engine displacement.
This is the fourth time that a flat engine from Porsche got the award. In 2007, the engine of the Porsche 911 Turbo won the accolade in the category of three to four-liter engines.
In 2008, the turbocharged 3.6-litre flat engine with 480 hp won in the open displacement class. In 2009, the 3.8-litre six-cylinder engine of the 911 Carrera S was judged as “Best New Engine.”
