At 2.6-sh second mark your car accelerates with more than 9.8m/s^2 to get to 60. But even lower accelerations will glue you to the seat because gravity acceleration affects every part of your body. Where as the car grabs you by the butt and yanks you forward. So - I think he has probably some vague idea of Newtonian physics but just didn't manage to produce coherent sentence.
How is more than one g accelleration possible? There is one g making the friction between the tyre and the road.
I think this is intuitively wrong for a vehicle with a gear wheel locked to geared track: the gears push against each other and acceleration would be possible even in a zero g environment. Now, cars don't have gear wheels, but I assume the same principle applies.
Edit - here's a more stringent discussion: http://physics.stackexchange.com/questions/75032/maximum-acc...

#13Not sure I agree with the terminology of the article (fast rather than quickest accelerating), but I thought this quote was special: > Speeds like this offer more Gs than Earth, so the rate of acceleration is faster than falling. It can feel difficult to support your head and shoulders if you don’t lean back on the headrest.
1 g is nothing.
"A hard slap on the face may impose hundreds of g-s locally"
"Early experiments showed that untrained humans were able to tolerate 17 g eyeballs-in (compared to 12 g eyeballs-out) for several minutes without loss of consciousness or apparent long-term harm" https://en.m.wikipedia.org/wiki/High-G_training

Indeed. My weak Google-fu indicates that the coefficient of friction of tyres against a dry road surface is something like 0.9, so there must be some improvement in tyre technology here just to make the thing go without creating a thick black smelly line on the road.

Acceleration of more than 1g is probably not possible for 0-60; there isn't much of that speed range that would allow for downforce (downforce would only start have a tangible effect after approximately 50mph (80kph)), and there is no other appreciable way for the car to generate more friction with the road that doesn't scale with vehicle mass.
I suspect what the OP was trying to get at is the vector addition of gravity plus the forward acceleration of the car means that the apparent scalar force feels substantially higher than normal (i.e. 1g downwards); it's just poorly worded.

The cars also gets pressed down by aerodynamics.
But downforce isn't appreciable until over 50mph (80kph), short of having stupidly oversized wings (which would drastically slow your acceleration) or active downforce (fans etc).

Is it still called the "gas" pedal on an electric car?

No they actually mean what they write - 1g gives you 0-60 in 60*1609/3600/9.81 = 2.73 seconds. The way to get that friction is probably to use a particular combination of tires and road. It's equivalent to standing still on a 45 degree slope -- not impossible, but definitely a risk of slipping there.

You're not the target audience for their top-of-the-line P100D. It's aimed at people who would otherwise buy Bugatti Veyrons, Ferraris, etc., and range probably doesn't even come up in their decision making process. The Veyron has a range of 50 miles at top speed, for example.
