There’s an owner demanding a buy back after getting the results of his poor Tesla dyno. In fact his dyno tested Tesla performed so poorly that the man is even considering suing the Silicon Valley manufacturer. And while this man is angry about his dyno results, the over estimation of horsepower is nothing new.
Manufacturer horsepower claims have always been a source of contention. There’s a good reason for this phenomenon. Some cars simply aren’t what they are advertised to be. Other owners don’t realize that horsepower estimations are never at the wheel.
Whatever the reason, this owner is piping hot about his Tesla dyno. With all the recent scandals revolving around Volkswagen and manufacturer lies, it appears consumer confidence continues to take a hit.
Man Angry with Tesla Dyno
The Tesla owner, a Mr Sacha Barnes, from Melton Mowbray in the UK is furious. Upon visiting his local speed shop to have his Tesla dyno tested, he didn’t see the 691 horsepower figures he was expecting.
Mr Barnes is no stranger to performance, also owning a Nissan GT-R. In fact he felt as though his Tesla Model S was incredibly underpowered all things considered. So consider his surprise when he got a Tesla dyno that read 300 horsepower lower than what he expected!
At just 393 rated horsepower, let’s just say that the Tesla dyno didn’t calm Sacha down. Instead, following the results, Sacha demanded that Tesla buy the car back at a full refund.
“Sacha got his Tesla dyno results today. He found it maxed out at 393bhp”
Could this really be the case? Could Sacha’s Tesla Model S really be putting down just 393 horsepower?
Well no, as it turns out it’s not that easy. You see there’s a lot of misunderstandings when it comes to dyno tuning. One of the common mistakes people make when prepping for the dyno is not understanding the process.
Because a chassis dyno reads the torque put out by the vehicle and calculates horsepower, the function of the P85 is far different. When you dyno a Tesla, you are reading just the output from one of the P85’s onboard motors. According to Tesla, the combined output when the Model S is at speed is where the horsepower racing comes from.
Tesla spokesperson went on to elaborate on the point of Tesla dyno numbers.
“A true indication of EV performance that is directly comparable to an internal combustion engine is the 0-60 mph time and torque figures we quote.”
Although those who understand dyno tuning know what she means, I don’t think the Tesla owner does. According to reports, Tesla is organizing a buy back, which should make Mr Sacha very happy.
