One thing I can't get my head around is that a pretty popular option on the Tesla is 21" wheels fitted with Michelin Super Sports tyres - they must suck a fair bit of range out of the batteries with the footprint and rolling resistance?!

It's all interesting and impressive but if there is no smell of petrol when ''recharging'' and exhaust fumes then I'm not interested, sorry

Other than that a great car

And that's what I said, at first. As the old saying goes, don't knock till you've tried it ...

Tesla do quote a slightly lower range for the 21", but only marginally so: I think this is because, as a proportion of the total battery power and overall vehicle weight (a lot of which is batteries ), the wheel/tyre combo only makes a marginal difference.

I was speaking to a Bosch rep a few months back who suggested that battery swapping may become more common over time -
i.e rolling out a set of battery swap points at service stations over the country.

Apparently some of the electric battery technology is so expensive that they are also looking into the cost of leasing plans for batteries

Tesla's battery is still a huge set of Panasonic cyllindric consumer batteries. Yes, Tesla buys consumer batteries from Panasonic to build their car batteries. Perhaps very smartly managed, but still a set of old small batteries. There is no real advancement in battery technology with Tesla's arrival. What humanity needs is a breakthrough in battery technology. We need batteries with 1000x capacity that are 1000x faster to charge.

Behold - radioactive decay - giving off a stream of electrons for 10 years from a grain of rice sized bit of plutonium.

It's 7104 of the below to be exact(possibly slightly modified), just in a big case with liquid cooling and battery management to ensure equal charging/discharging. If you got one of those battery banks after testdrive you have 1 of these batteries inside it.

Wow. Imagine if you had to turn it upside down and replace that lot, one by one, every time it ran out of juice!


And there was I expecting to see two huge Energizer batteries underneath.

There is a guy not far from me who reconditions and rebuilds batteries for hybrids so that should also be possible for Tesla even if battery is quite a bit bigger on fully electric car. http://www.ebay.co.uk/itm/LEXUS-HYBR...item43dd6c2471

This from Wikipedia: 'In 2013, Tesla canceled a 40 kWh version of the car due to lack of demand, stating that only 4% of pre-orders were for the 40 kWh battery option. Customers who ordered this option instead received the 60 kWh pack, with charge software-limited to 40 kWh (142 miles). It has the improved acceleration and top speed of the bigger pack and can be upgraded to use the full 60 kWh for US$11,000'

If this is true, very cheeky from Tesla to charge $11k for software upgrade to enable extra battery capacity which is already there physically. I imagine you ring them up, give your card number, they push an upgrade through the mobile network to your car and next time you get in battery have gone from 40kWh to 60. I wonder if you can jailbrake and modify it yourself but then again that would probably void warranty.
