Drag coefficient. It was the first mass-market … The Model S also hasn't technically entered production yet, so it's not exactly the most aerodynamic car you can currently buy. With a coefficient of drag that's just 0.208, the updated Model S narrowly beats out the Lucid Air, but there's a … This reduced the total drag coefficient (Cd) by 0.005.” Independent Aerodynamic Study of Tesla Model 3 … “The vehicle’s total drag was reduced by 2.3% and the rear downforce was increased over baseline by 34.7%. This comes hot on the heels of the updated Tesla Model S … The front bumper shape allows the wind to hit squarely on the front wheel. It determines how the car handles, its fuel efficiency, and maximum speed. As a result, the Model S is able to offer features such as a front trunk (a "frunk") in addition to a large rear trunk space and an enlarged front crumple zone compared to the typical combustion engine powered vehicle. The lower the coefficient, the better aerodynamics the model has. In the world of green cars, the Toyota Prius is a legend. The Model 3, when tested, clocked a 0.21 drag coefficient. Tesla says first deliveries won't begin until March for the Long Range or the Plaid, while the Plaid Plus won't get to customers' hands until late 2021. Infiniti Q50: 0.26 Cd. The Tesla Model S uses a streamlined body, a minimalist grille, aerodynamic mirrors, a hidden door handle, and rear diffusers to give it’s tear-drop shape such a low drag coefficient. With Lucid Air deliveries set to commence in the next month or two, it could potentially still take and hang onto the aerodynamics crown, at least for a bit. That number also nicely rounds up to 0.21 -- and that matches the Lucid Air's claimed figure. 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. If the pressure is the other way around, it will create a downward force, called downforce. F d = drag force (N) c d = drag coefficient. It's got a completely new interior with a crazy steering wheel, lots of updated tech and a Plaid Plus model that promises over 520 miles of range. The front face redirects most of the air to the top of the car to increase downforce, making the car handle better. Mercedes says the EQS achieves a 0.20 coefficient of drag, making it the world's most aerodynamic production car. So it’s smooth and flat, allowing the low-pressure air to flow smoothly along the bottom. The Tesla Model S Plaid has a drag coefficient of 0.208, which is the lowest that you may have heard so far in the industry. Tesla also can't claim that the Model S is the most aerodynamic production car ever, either. Aerodynamics is an often-overlooked factor of a car. For comparison, the $4.700.000 Lamborghini Aventador can only do 0-100 km/h in 2.5 seconds. https://enrg.io/explaining-the-tesla-model-s-drag-coefficient As a car moves through the air, the car displaces air around it, resulting in a force exerted back to the car. It’s able to go 0-100 km/h (or 0-60m/h) in just 3.7 seconds on the base model, and an insanely quick 2.4 seconds on the performance model + ludicrous mode. The rear diffuser accelerates the air exited from underneath the car, so when it meets the air coming from the top of the car, it doesn’t create much turbulence. Drag Area= 7.8 ft2 The Leaf is the boxiest shape we wheeled into the wind tunnel, and it has this test’s second-largest frontal area at 24.5 square feet. Tesla claims that the new Model S has the lowest drag coefficient on the planet (0.208 cd). Nevertheless, the Model S being the third most aerodynamic production car ever is still quite an impressive feat. The drag function is: p = Mass density of air (1.269 kg/m or 0.12 sq/ft). The rear-view mirror has a teardrop shape to decrease the aerodynamic drag further. Com-bined with a 0.32 drag coefficient, that yields a 7.8-square-foot drag area. Since the drag force is negated, efficiency also improves because the car will consume less fuel for the same distance. People rarely mention “aerodynamics.” While it’s true that aerodynamics is not the absolute most important factor, it determines several important factors about the car in a very subtle way. Model S has an insanely powerful explosive power. For reference, Tesla’s most aerodynamic production car is the Tesla Model 3 with a Cd of 0.23 — Next-gen Tesla Roadster is expected to break all aerodynamics records for a production sports car, officially no drag coefficient for the 2020 Roadster is announced yet. This results in a mere 77 pounds of drag force exerted on Tesla Model S. So, how do Tesla engineers manage to create a 0.24 drag coefficient? The lower the drag, the faster the car can run. The topic of Cd (drag coefficient) is one of frequent controversy and misunderstanding. A new source with connections at Tesla’s design group has informed me that late stage tweaking of the Model 3 is being done with an eye towards extreme minimization of wind resistance. Given the Plaid Plus model claims a 520-mile range, it's likely that one. The revised Model S Plaid has a drag coefficient of just .208, one of the lowest ever on a production car. Finally, the rear bumper also includes a diffuser in the bottom. © 2021 CNET, A RED VENTURES COMPANY. The drag coefficient number of Tesla Model S is 0.24. To demonstrate the importance of aerodynamics in an electric car, we’re going to take a look at one of the finest electric vehicles ever made: the Tesla Model S. Aerodynamics is essentially a set of interactions between air and moving objects. Ford F-150 Lightning to Tesla Cybertruck: Electric truck roundup. Ultimately, this allows for higher speeds and improved power efficiency. If the pressure on the upper side is less than the lower side, it will create an upward force called lift. In electric vehicles, the effect becomes more pronounced because power management is vital to its overall performance. It would be convenient for this study to make an absolute statement about the Cd of the Tesla Model 3, however, there are many ways for a vehicle manufacturer to calculate Cd. That force exerted by the air is called drag. Tesla Range is reportedly 390 miles, undoubtedly enhanced by a very low drag co … With a coefficient of drag that's just 0.208, the updated Model S narrowly beats out the Lucid Air, but there's a catch or two. Aesthetically, the new Tesla Model S has a slightly cleaner exterior with optimized aerodynamics. Speaking of aerodynamics, Tesla is claiming the “lowest-drag car on Earth” with a drag coefficient of 0.208 Cd.. The Model S is notable for being designed from the ground up with an electric powertrain in mind, unlike other electric vehicles where the manufacturer has simply swapped out or supplanted an internal combustion engine with an electric motor. Downforce makes the tire grip the road better. A car with good aerodynamics shapes how the air pushes the car in some ways that benefit the vehicle in terms of explosive power and fuel efficiency. The drag coefficient or coefficient of drag is related to the car's aerodynamics as it denotes the resistance to the air of the front surface of the vehicle when it is in movement. Tesla Model 3 Elon Musk's electric cars are already breaking the mold, but they're also some of the most aerodynamic cars on the road. Tesla Model S Aerodynamics, 2014 Honda Accord Hybrid, Mercedes Plug-Ins: Today's Car News Introduction To Our Used 2001 Honda Insight Hybrid Tesla Model 3 To Aim For 0.20 Drag Coefficient: Report Where the 2012 Model S came with a coefficient of 0.24, Musk aimed for a drag coefficient of 0.21 for the Model … The drag coefficient measures how much air and wind resistance the vehicle encounters when it’s driving, the model Y on this list has the lowest coefficient of drag at just 0.23. Based on that function, we see that to get a low drag force, we need to reduce the drag coefficient and frontal area of the car. What's particularly interesting about the Q50 is that once you start getting high … Tesla Model 3 misses drag coefficient target Tweeted by Elon Musk back in April 2016. The lower the coefficient, the better aerodynamics the model has. The S earns our top slot by virtue of its larger 25.2-square-foot face and lower 0.24 drag coefficient, which yield the same 6.2-square-foot drag area as the Prius. At the same time, its frontal area is 25.2 square feet (2012 Model S). The General Motors EV1 and Volkswagen XL1 both boasted 0.19 drag coefficients, and the VW at the very least most definitely is considered a production car. [better source needed] Tesla said it would have a 5-Star safety rating and have a drag coefficient of Cd=0.23. The door handle is cleverly tucked in within the body sides, allowing air to slide smoothly along the sides. By creating a better grip, you improve handling and cornering speed. 700 HP Electric eCOPO Camaro Hits the Drag Strip (w/ Video), Elon Musk Admits: Tesla Model 3 Has a Brake Problem, THIS is the Tesla Model S Shooting Brake You Want, Tesla Model 3 Track Mode Unlocked - Sets Track Record, Can You Do Maintenance On Your Own Electric Vehicle, Which Electric Vehicles Come With Range Extender, How Much Does a Tesla Battery Replacement Cost. 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. This is lower than the Tesla Model S drag coefficient of Cd=0.24, which, in 2014, was the lowest among the production cars of the time. The reduction of drag in road vehicles has led to increases in the top speed … Subscribe to Roadshow's newsletter for the latest car news and reviews, delivered to your inbox twice weekly. 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. Tesla says the new Model S is the world's most aerodynamic production car.
