Plaid Plus model that promises over 520 miles of range. But buried in the deluge of info is a new superlative that Tesla is claiming: The updated Model S is the most aerodynamic production car in the world, with a drag coefficient of just 0.208. Now there are a couple of technicalities here. Tesla doesn't say which specific Model S achieves that 0.208 figure, whether it's the Long Range or one of the Plaid models and if it's with the 19- or 21-inch wheels. Given the Plaid Plus model claims a 520-mile range, it's likely that one. That number also nicely rounds up to 0.21 -- and that matches the Lucid Air's claimed figure . Lucid hasn't given a specific drag coefficient that goes beyond the second decimal place, so its 0.21 claim could perhaps have been rounded up. We're not sure about that, but we are sure the aerodynamic one-upping won't stop anytime soon. Refreshed Tesla Model S has a Knight Rider steering wheel +13 More
