How to justify buying the new Roadster

[hbouw]

Easy: think how empty your life would be without one!

Anyone else thinking the 10,000Nm typo of 1,000 is funny, the internet is blowing up thinking this thing is going to have 7,000lb/ft of torque.

There is no justification. If you want it, and can afford it, you buy it.

Personally... I'm going to buy a lottery ticket.

I think this is actually the most persuasive argument I've read yet. Problem is, I was planning to use what would be the reservation fund to get the 3.0 battery. Will my current battery last another 3+ years?

Why do you say it is a typo?
Assume Roadster weighs 5000 lbs/ 2273 kg.
0-60/ 0-26.8 m/s in 1.9 sec
Average acceleration is 26.8/1.9 = 14.1 m/s^2
Average force is 14.1 * 2273 = 32,084 kg*m/s^2 (newtons)
The original roadster rear tires were P225/45R17 , with a diameter of .553 meters, radius of 0.266 meters (less torque needed)
P100D has P245/35R21 with a diameter of 0.619 lets go with those:
If the tire diameter is 0.619 and the radius is 0.3095, the car requires 32,084 * .3095 = 9,930 nm to achieve that acceleration.

Since I'm running numbers, to accelerate 5000lb to 60 MPH in 1.9 seconds requires: 227 Wh at a rate of 430 kW.

It’s a ‘4 seat’ family hauler right? Right? Need more ideas to pitch to wifey lol

I showed my wife this thread title. She just laughed...

My feeling is if you have to justify it, then you shouldn't buy it.

Then you're measuring the force over time. I highly doubt tesla went from 931nm in the p100 to 10,000 in the roadster and only dropped three tenths.

I bet you are loads of fun at cocktail parties

Actually you're calculating the moment at the tip of the tire with that equation. That's retarded, no other place advertises torque like that. That's like saying a corvette has 600lbs of torque BUT when you multiply it through the gearbox reduction and then multiply it by the radius of the tire you'll have a billion nm. Add this to another way Tesla manipulates information to make themselves seem holier than thou.

Running a 4800 lb P100D with 0-60 of 2.5 seconds, I get 7,245 nm. Which is also 739 kg-m.

English units 7,200 ft lbs at 1 foot is 7200 lbs of force. If the Roadster weights 5,000 that's an acceleration of 7200/5000×32=46 ft/s^2. 60 MPH is 88 ft/s, so 0-60 is 88/46 = 1.9 seconds.

Keep in mind, these are all torque at the wheels, not engine torque. In an ICE, the engine torque would multiplied by the transmission and rear axle ratios.

Tesla is also SpaceX people, thrust is what accelerates. Saying 600hp at the engine tells nothing about acceleration precisely because you would need to know the intermediate ratios and losses.

I so enjoyed watching the many videos of those G A M that tried to explain what they just went through after their ride. I think there is no justifying if once you had a test ride and fall in that trance.
G A M = Grown Ass Men.

 

[Darmie]

.. and How did they keep this thing such a secret? Where did they do the testing? I think that Gigafactory has a runway in it.

 

[12Pack]

Actually it’s a really good deal - only 20% of the cost of a LaFerrari or a P1.

 

[Darmie]

.. So if a Boat is Bust Out Another Thousand & Jeep is Just Empty Every Pocket, what the heck would this Roadster be considered?

 

[stevejust]

I never thought someone in the market for 200k car will use fuel savings as a rationale behind

I never thought I'd be in the market for a $200k car, and didn't even know I was until November of 2017.

How to justify new Roadster?

• Midlife crisis?
• Need to be faster than your friend's Lamborghini?
• Your collection of Tesla products won't be complete without it?
• Can't pickup girls at your Ivy League College without one?
• Always got to have the latest super car?

There are really many fine reasons for extremely wealthy people to buy this sort of product. I just hope that 1,000 of them drop the money quickly to help Tesla get the capital it needs to get the Model 3s churning out.

OK;

• Midlife crisis- that's long gone for me. I did that with Ferrari and Porsche;
• Faster than my friends Lambo- My S P85D already did that a couple of years ago. Recognising his one Gallons Per Mile he gave me a few li-ion cells for emergency energy.
• Obviously no Tesla collection is plausible without both original and new Roadsters, at least one S and X;
• ...pickup girls at Ivy. A young borrower of my S P85D informed me that that car works for the intended purpose. He only used it at Princeton;
• ...the latest... that is a legitimate Jay Leno-style argument.
