It has taken us more than 18 hours, with multiple transfers, to get to Yellowknife, in Canada’s Northwest Territories, from Germany. But there’s a good reason for it. We have been fortunate enough to be asked to join Porsche’s severe winter tests of the next-generation Porsche Boxster.
Alex Ernst, the chief conductor of this secret test, explains to us that even though there are other possible locations in northern Europe with the similar latitude, such as Ivalo or Rovaniemi, both in Finland, Yellowknife is better suited to this type of testing because of the consistency of the low temperatures – around -20deg C – from December through to March. He also adds, with a wink, that although Canada’s snowy wastes are filled with harmless tourists from Japan here to see the northern lights, there are no automotive paparazzi.
Given the promise of such cold conditions, we’re a bit disappointed that the temperature is a positively warm -6deg C when we arrive, although it drops to -11deg C by the next morning. The next-gen Boxster is covered with snow when it appears in front of us in Yellowknife. After the crew finish scraping the ice from the windscreen, we head to the testing site outside of Yellowknife’s city limits.
“You may think these are extraordinary conditions for a test drive,” says Joachim Meyer, Boxster chassis specialist and my driver for the morning. “However, we are simulating the daily commute for general drivers and evaluating the efficiency of the heater and defroster, or checking the warmth of the seat heater. The steering wheel heater is also tested. Porsches are sports cars, but that doesn’t mean we can ignore comfort.”
The 986-generation Boxster was born in 1996. Three generations later, Porsche’s roadster is facing a significant turning point in its evolution. Its bigger brother, the 911, has already gone through the transition to downsized engines with turbochargers.
What we know today is that there will be two types of turbocharged flat four available for the new Boxster, both developed from the new turbocharged flat six engine (codenamed 9A2B6T) created for the recently facelifted 991-generation 911.
In essence, Porsche has got rid of two cylinders in order to create the new turbocharged flat four (codenamed 9A2B4T). The base 2.0-litre boxer unit has a single turbo and is expected to make around 295bhp and 258lb ft. This engine’s bore and stroke dimensions are 91mm and 76.4mm respectively and these, as well as the cylinder pitch, are the same as the 911’s.
The Boxster S will have a larger bore and stroke than the base model, increasing engine capacity to 2.4 or 2.5 litres and making around 355bhp and 295lb ft. The rumour is that a turbocharger with Porsche’s Variable Turbine Geometry (VTG), as used by the 911 Turbo, will be fitted to this engine.
