Updates Saturday 18 & Monday 20 November – two new videos – text updates in this font.

Update 15 December – added Tesla's video of the entire event – 35 minutes.


Some highlights:

● 500 mile (800 km) range –
full load at highway speed
Megachargers add 400 miles of range in 30 minutes
Network of Megachargers world wide
● driver sits in the centre with a screen on either side
● passenger/alternate driver seat is behind & to one side

● one million miles (1.6 million km) without a breakdown! – guaranteed! – with four motors, two can fail & the truck can complete delivery – & still out-torque a diesel

“You never need to replace brake pads ever.” – long brake life is a recognised advantage of electric vehicles because in large measure, braking is regenerative – also improving range, efficiency & total cost of ownership

● enhanced autopilot standard1
● platooning included2

● torque vectoring enabled by 4 motors with microsecond control makes jack-knifing “impossible”

“A diesel truck will be 20% more expensive than a Tesla semi per mile ... worst case scenario.”

● with platooning, make that 100% more efficient
● with platooning, efficiency exceeds rail
“Production begins 2019.”

And, “some unannounced”?3 – the new Tesla Roadster



● 0-60 mph 1.9 seconds – that's 1.44 g4 – first production vehicle to go under 2 seconds

● 0-100 mph 4.2 seconds
● quarter mile 8.9 seconds
● 250 mph (402 km/h) top speed

“The new Tesla Roadster will be the fastest production car ever made – period.” This means a top speed in excess of the 257.87 mph (415 km/h) (arguably 267.856 mph (431.072 km/h)) attributed to the Bugatti Veyron Super Sport, World Record Edition.5 Alternatively, as Elon Musk has done before, it may be a reference to the 0-60 mph time – &/or 0-100 mph &/or quarter mile times.

● 200 kWh battery pack
● range 620 miles (just under 1,000 km)

three motors – two driving the rear, one driving the front

● 2+2 seating
available 2020

“Roadster Test Ride” video below, includes 0-60 mph in under 2 seconds.

4 60 mph = 96.56 kph
= (96.56 * 1000) / (60 * 60) metres per second
= 26.822 metres per second

final velocity = initial velocity + acceleration * time
26.822 = 0 + acceleration * 1.9
26.822 = acceleration * 1.9
26.822/1.9 = acceleration
acceleration = 14.117 metre/sec/sec

Acceleration due to gravity = 9.8 metre/sec/sec

acceleration = 14.117 / 9.8 g
acceleration = 1.44 g
