Ferdinand Porsche is said to have once said that no vehicle should be allowed to go faster than it can stop. The Tesla Model S Plaid, from that metric, would shock the legendary engineer.
In a new video from Engineering Explained, Jason Fenske points out that in the Motor Trend tests, the Tesla Model S checked it is referred to as accelerating from 0-60 mph (97 km / h) in just 2.28 seconds on an unprepared surface, while it goes from 60-0 mph in 2.38 seconds. Plus, it accelerates to that speed in just 98 feet (30 meters), while stopping at 104 feet (32 meters).
This is the same quality that has led some to suggest that the Model S plaid it doesn’t have good enough brakes for the enormous speeds it can create. With 1,020 hp (1,034 PS / 761 kW) and a weight of 4,816 lbs (2,185 kg), the super sedan was running a quarter mile in about nine seconds, but its 15-inch cast iron sports brakes.
As Fenske points out, the Model S Plaid’s brakes and their 60 mph performance are perfectly adequate for road legal, and not-so-different speeds. from the Taycan Turbo S.. However, they are by no means exceptional, unlike the acceleration performance.
In fact, as a video from other automotive YouTube Jason (Cammisa) argues, big brakes made from exotic materials aren’t usually designed to improve braking performance on a stop. They are normally designed to prevent the brakes from overheating when used over and over on a track. Indeed, as some have pointed out, Tesla’s Nurburgring lap time appears to show the driver rolling up and up at the end of some straights, a technique used to help cool the brakes.
The very fact that the Model S Plaid is able to use more grip from its tires on acceleration than on deceleration, however, is pretty impressive, regardless of material. Fenske argues that an important factor enabling this is an electric motor’s ability to apply torque faster than a Byzantine internal combustion engine. So when an electric vehicle reaches its grip limit, it can adapt more quickly to find the threshold. Amazingly, it can do this even faster than most ABS systems.
While there are other factors involved, it should go to show that the Model S Plaid’s brakes are adequate for street (legal) use, but may not be up to par on a circuit. This is a topic that may not be exclusive to Tesla, however, as electric vehicles progress – but, on the other hand, how many Model S Plaid buyers will actually take their cars to the track?
