Much as I would love to see a UK manufacturer have a success story I am a bit skeptical if those specs / prices are correct. Compared to the tesla it costs 2x as much yet has less range (150 miles) and is slower (0 to 60 in 5 sec). Looks good from some angles though.

Got there eventually :-)
I agree. Gone are the days when a handful of engineers could build things like this in a garage.
In the ICE world, niche manufacturers would buy in powertrains from larger firms, often using them in innovative ways (eg Trident Vehicles' use of an 8-litre truck diesel engine in their Iceni sprts car) to differentiate themselves from the market. IMHO the future for firms such as Lightning and Delta is to do the same thing.
superfast charging in just 10 minutes; is that true? Very cool if it is.[/QUOTE]
I honestly don't see how they can charge it that fast either. The batteries are 44 kW. That means you have to provide that much power in 10 minutes.
To put in perspective, the US, residential are usually 240 V, and up to 200 A. You would need the power from 5.5 houses (full- assuming no losses and nothing else is plugged in) just to charge it in 10 minutes.
Just from a safety standpoint, I would be very hesitant of messing with something that pulls more power than 5 combined houses.
The only thing that I can think of is using a 600 V. I've dealt with 600 V @ 315 Amps a few times (that's not even enough to charge it that fast), and that's insane voltage and amps.

It would have to be done from industrial 480 volt three phase power, or with a larger precharged dump pack. Point is that the Altairnano cells can take it if you can provide it.
Yes, the Lithium Titanate can take that type of charge- it's a very stable chemistry (I wish the Tesla Model S used that)
It just seems like alot of amps over a short period of time. At 480 V, it's like 550 A;
that's about 25 times what's used in an electric chair

If the Model S used that chemistry the range would be about half, and the cost would be about double. Other than that....
I spent a couple of days exhibiting the Tesla next to the Lightening GT at the Eco Technology Show. The folks on the stand confirmed that they intend to build 20 cars next year with both 43kW AC and unknown kW DC charging.
It was a very busy time for both stands so I'm not sure who got the most attention.... the Lightening GT is enormous and looks like a Super Car which IMO the Tesla does not.... however, large numbers of people comment on how much they love the Tesla Electric Blue colour, and everyone is impressed by the specs and the fact that it's a production car (unlike the Lightening).
