> Most (all?) production electric cars struggle to do a full power complete lap of Nürburgring Nordschleife without heat-related issues. They're amazing at the Stoplight Grand Prix (and I enjoy my cheap LEAF daily), but struggle as racecars.
No, they just don't make electric race cars. There is not yet sufficient demand. Properly cooled electric batteries make as much power as f1 engines without breaking a sweat.
Sony VTC5a cells[1] are 85% efficient at their full rated power, and can sustain that continuously for their full capacity. They do 2.4 kW/kg without a gas tank, exhaust, turbos, or intake. Their ten second burst current is double that, 4.8 kW/kg. That puts it at the same level or higher than current f1 engines, which run less than 2000 km.
If you count the weight of ancillaries as you should, electric batteries come out way ahead, particularly the most powerful ones.
> I was just responding to a previous post claiming that "performance cars in a given class can weigh DOUBLE the lightest cars in the same class", nothing more. If you claim the span is much less than double, then I agree.
I was referring to the A-F market segments when I said class, not saying that performance have a weight range that large. Performance or luxury cars can weigh twice as much as a lightweight car of the same rough size.
