Porsche's E-Shift System Pays Homage to PDKPorscheThe addition of simulated gears to the 2027 Porsche Taycan bucked a few expectations. Porsche insiders previously spoke out against simulated shifting in electric vehicles, only to reverse their opinions after a drive in a Hyundai Ioniq 5 N. But even if it was inspired by an outside automaker, Porsche's newest dynamic software is hardly lacking in brand synergy.For one, the E-Shift system is tailored to feel like Porsche's PDK transmission, including the real-world kick included with a proper dual-clutch shift. Kevin Giek, vice president of the Taycan product line, said the transmission tuning was modeled after the transmission in Porsche's combustion-engine models. "More or less, this is a real PDK, as you know it from the combustion cars, like a Panamera or a 911. We have eight gears, two overdrives, and you can use them like you're driving a PDK," Giek said in a media briefing.Of course, the Taycan also features two real gears, which offer different options for accelerative take-off and high-speed efficiency. Giek explained that pushing the simulated first gear to redline is akin to pushing the real first gear to its maximum speed, but that the remaining gears are tuned for shifting pleasure.AdvertisementAdvertisementBut controllable shift points aren't the only reason enthusiasts favor manual transmission or paddle-shifted vehicles. A big part of the shifting experience is about hearing the engine working through its revolution range. Porsche is especially aware of this, as its 911 and 718 sports car lines offer strong exhaust notes. But imposing another vehicle's exhaust note on an existing Porsche product felt like sacrilege to Giek.Porsche"It's an emotional tool for driving experience. It was very important to us that we have a real Taycan sound. That means you have no V-8 sound behind it. It's just a new development belonging closer to the Taycan," Giek said.In practice, the E-Shift brings a variety of Porsche influences to its soundscape. High-rpm downshifts rumble that is admittedly reminiscent of Porsche's twin-turbo 4.0-liter V-8, while mid-range pulls pipe in a resonant intake noise akin to the brand's naturally aspirated flat-six models. Shifting into the Taycan's faux-overdrive gears nearly eliminates the soundscape, save for a sonorous note tied to accelerator pedal position.Porsche's sound designer, Maximillian Geiger, said the sound is directly attributable to the Taycan line. "This does have a specific partial electric sport sound, and that's the basis of the sound of the virtual gearbox—of the E-Shift sound. We just created a sound for the whole rpm range; a different sound for acceleration, recuperation, braking, and, of course, rev limiter and launch control," Geiger said in an interview with Road & Track. "Sound is such an important thing in feedback. And if the sound is missing, you won't know what the car is doing."AdvertisementAdvertisementThe not-so-secret behind the soundscape: Much like the Hyundai Ioniq 5 N and its fake-shift system, the core of Porsche's E-Shift is speakers at the front and rear of the car. The rear speaker functions as a sort of exhaust system, only it pumps out sound waves, instead of carbon monoxide. The front speaker has a bigger responsibility: to not only pump in an rpm-appropriate noise, but also to help rumble the interior of the vehicle along with the falsified engine speed.Porsche"What you see, what you feel by the shaking during shifting, for example, is vibrations; you can feel the vibrations from the front speaker, and [hear] the sound, of course. The vibration, you can feel with your feet and a little bit with your hand, is mostly coming from the speaker. That's something we wanted to have there—because, in my opinion, it's a very important part of all the feedback," Geiger explained.The future of Porsche's E-Shift system beyond the latest Taycan is unclear. While the company is moving away from its previously planned electric full-court press, the recent addition of the Cayenne Electric to the line and the Taycan's new updates indicates that EVs are still central to the Porsche mission. It's not immediately clear if the Taycan's E-Shift system will be carried over to other Porsche EVs, but I sure hope it does.You Might Also LikeIf You Can Only Own One Car, Make It One of TheseThese Are the Most Popular Cars by State
