I'd say no. You can't make *any* generalities like this because the 
differences in construction are much larger than the average differences 
between the different chemistries.


With all chemistries (lead-acid, nicad, nimh, lithium or whatever) you 
can get cells that are optimized for fast charging, or amphour capacity, 
or life, or high current, or cost... but not all at at once! Improving 
one generally hurts the others.


So to get a 4:1 difference, just compare one hand-picked battery that is 
specifically poor to another hand-picked one that is specifically good 
at the parameter you are trying to highlight.

Do lithiums charge 4x faster than lead acid? Is this market positioning 
on their part?
It might be apples and oranges, with the center 60-80% of the lithium 
pack used, and say 100% of the lead acid, of course it will take hours 
longer to take lead to 100%.


That black striping looks horrible.  Among other things.

The car can achieve a maximum speed of 150 km per hour and
according to Vyas it will come in three battery options, the lead acid,
lithium ion and supercapacitors. “For each charge, the car can go 1,000 kms.
The lead acid version would take eight hours to charge, the lithium ion
battery would take two hours to charge, and the supercapacitors would take
less than five minutes to charge,” he claimed.

Is it just me, or does this seem too good to be true? That's twice the range of 
the Tesla...on lead acids? A supercap car for $40K? Supercaps that charge that 
much faster than A123 / CALB batteries -- and a charger that can handle the 
current? And a paltry 150 km/h limit for a low-slung wide-track aerodynamic car 
with battery pack with those specs?

I like the DeLorean / '80s Lamborghini styling. And, hell, if it's for real, I 
could even imagine saving up a few pennies for one -- or, at least, its battery 
pack.

I'm just very, very, very skeptical that the claims will survive past the 
showroom floor.

Like Carl Sagan said, "Extraordinary claims demand extraordinary proof." 
So where is the proof of their claims?


For some reason, EVs attract world-class exaggerators, liars, and con 
artists that will say *anything* to get publicity and investors. The 
vast majority of press releases like this one are 99% wishful thinking 
and fiction.


So I remain skeptical. Let's wait to see if there are any *real* results 
from this company.

It's not just you.

I'd guess that they're trolling for investors. Sorry, no nibbles from me.

India’s indigenously-built SNEV car covers 1,000km with single charge

GUJARAT: A local Indian company has built an electric sports car, Super Nova
Electric Vehicle (SNEV), that can cover 1,000 kilometres with a single
charge of its batteries and at the speed of some 150 kms per hour.

The car, which has already an order list of 250 units, will cost between 1.5
to 2.5 million Indian rupees (24,000 to 40,200 USD).

Soon Gujarat could become the home to the country’s first indigenously
developed electric sports car the Super Nova Electric Vehicle (SNEV). Golden
Arrow Wireless Pvt Ltd, which has developed the car, is looking to have 50
acre land in the state to start manufacturing the car here.

Shashi Vyas, founder of Golden Arrow Wireless, said that the company already
had around 50 acres of land near Raipur in Chattisgarh and has already
signed a memorandum of understanding (MoU) with the state government there
to set up a manufacturing facility. “We are, however, looking at setting up
plants at multiple locations including Delhi, Mumbai, Bangalore, Raipur and
also somewhere in Gujarat,” he added.

Vyas was talking at the sidelines of the first automobile exhibition in
Gujarat, ‘AutoShow Gujarat 2014', where he has showcased the prototype of
his car. The car can achieve a maximum speed of 150 km per hour and
according to Vyas it will come in three battery options, the lead acid,
lithium ion and supercapacitors. “For each charge, the car can go 1,000 kms.
The lead acid version would take eight hours to charge, the lithium ion
battery would take two hours to charge, and the supercapacitors would take
less than five minutes to charge,” he claimed.

Golden Arrow has raised around 5 billion Indian rupees from investors so far
and is looking to raise more funds to start manufacturing the car, which is
awaiting approvals from the Automotive Research Association of India (ARAI).
“We would need around 25 billion rupees to set up the manufacturing sites.
We already have around 250 bookings, and can deliver them by end 2015 if the
ARAI approval comes through,” he said, adding that he has already spent
about 1,000 million rupees on developing the car.

Rashmi Urdhwareshe, director, ARAI said that there were no guidelines to
approve electric sports cars in the country, and that ARAI is in talks with
the Centre to come up with regulatory framework for such cars.
