Porsche has taken a step forward in its road tests for the Taycan, as prototypes of the German automaker’s first all-electric car were recently sighted sporting less camouflage, new tail lights, new headlight accents, and new wheels. The new Taycan prototypes look more refined and production-ready than the previous test mules the legacy automaker has been utilizing in its road and track tests for the upcoming vehicle.

The updated Taycan prototypes were recently photographed by CarPix, a group that tracks vehicles that are currently under development. Immediately noticeable in the new Taycan images is the reduced amount of camouflage used the cars. The headlights of some of the prototypes, for one, appear to still be covered with stickers, but the tail lights of the electric cars were already connected with an illuminated horizontal strip between them. This makes the updated prototypes’ rear appear very similar to that of the Mission E sedan concept car.

Also notable in the updated Taycan test mules were the vehicles’ wheels, which seem to be bigger and more aero-focused than before. Auto publication Top Speed, which claimed to have gained information about the prototypes, stated that they were informed the aero-focused wheels would likely make it to the production model. That being said, offering aero wheels for the Taycan makes perfect sense for Porsche, considering that they could optimize the range of the electric car. Tesla’s Aero Wheels for the Model 3, for one, is capable of increasing the sedan’s efficiency by ~10%.

Perhaps the most peculiar aspect of the updated Taycan prototypes were its fake exhausts. Being an all-electric car, the Taycan does not need an exhaust at all, and over the past months, it was thought that the test mules’ dummy exhaust pipes were just fitted on the vehicle to throw off onlookers. The updated Taycan prototypes still featured faux exhaust outlets, and what’s more, some cars actually had different types of exhaust outlets.

The Porsche Taycan is the German automaker’s long-awaited response to the Tesla Model S sedan. The all-electric car is equipped with two permanently excited synchronous motors (PSM), which are expected to produce up to 600 hp. Porsche notes that the Taycan would feature a 0-60 mph time of 3.5 seconds and a top speed of 155 mph. While these figures fall below the performance stats of the Tesla Model S P100D, Porsche notes that the Taycan would be capable of being driven hard on the track for extended periods of time.

Porsche expects to start the production of the Taycan sometime next year, with deliveries likely hitting their stride in 2020. To prepare for the all-electric car’s rollout, Porsche is building a network of Charging Parks, which are similar to Tesla’s Supercharger Network, that would allow drivers to charge their vehicles rapidly. Porsche plans to produce the Taycan at its Zuffenhausen facilty — the same factory that manufactures the Porsche 911, 718 Boxster, as well as the 718 Cayman. The company is aiming to manufacture 20,000 Taycans every year.
