Sorry, Dodge - Tesla Model S P85D is quicker than the Charger SRT Hellcat

Though it is debatable which is the better performance car, one fact is indisputable: the new all wheel drive Tesla Model S P85D is quicker than every four-door sedan in the world, including the Torque News favorite Dodge Charger SRT Hellcat.

Let’s get one thing straight from the start. Quick and fast are not necessarily the same thing, though the words are often used interchangeably. The newly unveiled Tesla Model S P85D with all wheel drive and the rear wheel drive Dodge Charger SRT Hellcat are both very, very quick and very, very fast. But one is quicker than the other, and one is faster than the other. We provide further perspective to a recent Torque News debate.

First: the Hellcat

Torque News is quite fond of the Dodge Hellcats, both the two-door Challenger and the four-door Charger. The Charger SRT Hellcat packs a phenomenal and loud 707 horsepower and 650 lb-feet of torque. It can make the 0-60 sprint in 3.7 seconds without drag radials, and a quarter mile in 11 seconds flat. The Charger Hellcat tops out at 204 miles per hour.

Tesla’s Model S P85D

The new all wheel drive system unveiled by Tesla last week is a truly remarkable example of what electric propulsion is capable of. The P85D adds a 221-hp electric motor to the front wheels to complement a re-tuned rear unit that is capable of 470 horsepower. Together, the system puts out 691 hp and 687 lb-ft of instantly available torque for some truly mind-blowing off the line performance. The drive mode that unlocks all that power? It is correctly labeled “Insane.”

Model S P85D has an official 0-60 time of 3.2 seconds, making it the quickest four-door production vehicle ever built. It can run the quarter mile in 11.8 seconds and reach a top speed of 155 miles per hour.

The most impressive part of the P85D is that adding a second motor and 221 horsepower actually improves the efficiency of the car. Despite an additional 291 pounds of weight, the unique efficiency curves of electric motors allow Tesla to optimize current flow on a time scale of milliseconds to keep the motors at a more frugal operating point.

Quicker, not necessarily faster

We will reiterate an important point: the Tesla is quicker than the Dodge. No internal combustion car, no matter how large the engine, can hope to compete with the P85D off the line. The fundamental characteristics of torque-speed curves mean that an all wheel drive electric car with 687 lb-ft of torque will fry any dinosaur-burner from a dead stop. That is reflected by the superior 0-60 time of the Tesla, and the advantage from 0-30 would be even greater.

Electric vehicles are limited by their batteries, however. Model S cannot sustain its maximum level of power as long as the Hellcat, largely because the batteries can only tolerate so much heat generation and obviously deplete quickly under high load. Hence, the Model S P85D’s governed top speed of 155 miles per hour.

That is why it is fair to call the Charger Hellcat a “faster” car than the new all wheel drive Tesla. It can go faster, and that is indisputable.

A deeper look

Model S also weighs more than the Hellcat, but not by a whole lot despite the heavy battery pack. The Tesla tips the scales at 4,936 pounds while the Dodge weighs in at 4,560 pounds. The greater power-to-weight ratio of the Hellcat lends it an advantage, though the aerodynamics of Model S are far superior.

Driving dynamics are also worth considering in any debate between the two cars. Tesla claims their new all wheel drive system will provide the “most capable road holding and handling of any vehicle ever produced,” and though that grandiose proclamation may not be verifiable, it is not misleading.

A powertrain that can instantly vary the torque split between the front and rear combined with the low center of gravity due to the floor-mounted battery and a perfect 50:50 weight distribution (vs. 54:46 for the Dodge) makes it hard to argue against the Tesla. The electric sedan is said to be able to post a very impressive 1G lateral acceleration.

The main advantage the Charger SRT Hellcat holds over the Model S P85D is its sticker price: the Tesla goes for about $120,000 while the Dodge is expected to be slightly more than half that. It also holds an advantage in any sustained high-speed driving, as Model S eventually has to limit the car’s output to protect the battery pack. However, if money was no object you would be insane (in this writer's humble opinion) to take the Hellcat over Model S as a daily driver on real roads.

The point here is that both cars offer truly incredible performance. Some people need the roar of a V-8 engine in their fast cars while Tesla drivers will tell you no sound compares to the thrill of flooring the accelerator in a Model S. But to each his own.

By not buying fuel for a TESLA a typical driver can put the savings in fuel of about $2,400/yr into an investment @ 5%/yr for 10 yrs at 3% inflation and gain about $30,000 for O & M and ? It is true that those who can, drive whatever they please. There is a small minority out there to this day who just love their HORSES. I believe that in 20 yrs or so, there will be a small minority of sentimentalists (like you "bigduke10") who will likewise love their IICE machines. I foresee that in about 20 - 25 yrs, people will be taking their grandkids to the museum or to special shows where ICE machines are displayed as they will be a rare sight on the roads. Indeed, people by then will choose to drive EV's as they are more cost effective, practical and desirable. We are transitioning to a new era in transportation just like they did in the early 20th century from HORSES to ICE machines. I hope you enjoy your ICE machine, but for me, I will choose an EV (Tesla) for my choice as will the majority of drivers. Better yet, one day "Scotty" will "beam me up" to where I want to go. The times are changing, get with it!
When a 50 year old Tesla brings 2000% of the original sales price like a Hemi Cuda does or a Shelby Mustang or a Cowl induction Chevelle does I will start to believe the BS you are peddling about electric cars, All you slot car freaks are in LA LA LAND!!!!!
Can 12" wide wheels fit on the rear of the Hellcat?
Personal opinion: I don't like the telsa at all; Challenger looks pretty more powerfull more musclecar alike, telsa looks like an audi, bmw, lincoln, meche, etc to me, I don't like it, let your old man buy the darn Telsa for himself xD
Wow - I would have thought you guys smarter than to legitimize a compare between AWD vehicle and 2WD. In any kind of "real" race - - these vehicles would be in very different classes. THere's no doubt AWD redistributes contact patch energy over greater surface area than 2WD - - and there's a practical performance advantage which results. The results have far less to do with EV versus ICE and far more to do with the physics of AWD vs 2WD.
