Let's just point this out: The '99 Honda Insight is not a bad car. Just did a test on Nürburgring 24H layout and my laptime was 9:06.426. Didn't cut any corners or anything. The thing is that when you perform weight reduction, it drops to about 700 kg, which gives excellent cornering and braking. And as the body is streamlined it tops out at about 250 km/h (which is the same as that 230 BHP Porsche replica in my avatar picture), even with its 995 cc 160-ish BHP engine. Fuel consumption is way better than GT3 cars and I strongly suspect that the tyres also last a lot longer with that lightweight body and low-powered engine.
