Tesla Motors Inc (TSLA) Secretly Adds Over 50 HP To Model S P90D Ludicrous

2012 Tesla Model S - Jay Leno"s Garage

Tesla Motors Inc (NASDAQ:TSLA) faced some issues with the power output calculation of its vehicles last year, leading to mediation with over 100 of Model S owners in Norway and change in Model S P85Ds advertised horsepower (hp) to 463, down from 691. The issuewas mainly related to identifying electric power concerning hp and the power output, which vary on the state of battery pack charge powering both the electric motors.

Following the updating of the advertised numbers,Electrekreported that the problem has been largely fixed. Though, the Ludicrous feature rolled out on the Model X made things more complex again. The Ludicrous mode, which is an upgrade for top-of-the-performance Model S and Model X, was introduced last year.

The Ludicrous Mode allowed the company to increase the upper limit of the power output of the sedans battery pack by 200 Amps to 1,500 Amps. It reduces 0-60 mph and quarter-mile acceleration times of the Model S to 2.8 seconds and 10.9 seconds, respectively. For the Model X, the 0-60 mph time reduces to 3.2 seconds and quarter-mile time to 11.7 seconds.

Although the SUV weighs roughly 600 pounds more than the sedan, Tesla advertises that both the models have the same powertrain providing similar hp and torque 532 hp with 397kW power output with the Ludicrous. Surprisingly, Model X owners have been able to replicate the performance of the P90D (Ludicrous), while the Model S P90D owners have been facing difficulty.

Despite having more weight, the crossover has been outperforming the sedan in terms of power output in max charge state. While the top-of-the-line Model X is able to achieve power outputs of more than 490kW, the P90D sedan barely crosses the 450kW mark.

Nevertheless, aTesla Motors Club(TMC) userShotgunF15Euploaded a log file of 0-60 mph launch on his new Model S P90D, delivered in March, which shows that the sedan achieved power output of as much as 494kW.

The tests were conducted after an over-the-air software update (2.20.30). Following the latest update (2.24.30), the owner was able to achieve 672 hp with 501kW on a full-charged latest battery pack (1071394-99-A).

In response to updated Model S output, a Tesla representative toldElectrekreiterated that both of the models have the same hp and torque rating.

Separately, Drag Times create a graph of power output of Model S P90D (Ludicrous), Model X P90D (Ludicrous), and latest Model S P90D (Ludicrous):

The data points show the latest sedan is able to catch provide the same output as the SUV and before now the out between the two models varied. It is possible that Tesla can introduce the leaked Model S P100D, which would provide greater output, to overcome the issue altogether.
