2015 Porsche Macan S: Doesn't Feel Turbocharged
July 02, 2014
Our long-term 2015 Porsche Macan S doesn't feel turbocharged. The power delivery of its 3.0-liter twin-turbo V6 is so linear and tractable that most people wouldn't know it was turbocharged from behind the wheel. It simply feels like a strong normally aspirated engine.
This is the product of a couple of different factors.
The first factor responsible for this seamless trickery is the engine's calibration (throttle and electronic wastegate tuning), which act to linearize the power delivery. However, there's another thing at play here: the PDK gearbox. The PDK delivers a relatively small drop in revs between gear changes and allows the throttle to remain open during gear changes, both of which keep the turbos (and consequently, the engine) on boil.
It doesn't sound turbocharged either. There's no sighing from the compressor bypass valves, no intake hiss, nothing to tip its hand regarding its artificially aspirated nature. All this, and it also still manages to have a vocal exhaust note.
