RE: Spartan-V: The 300kg Bike-Engined Track Car
Discussion

Our formula student car (V twin) was 198.5kg using carbon for only the bodywork, the lowest I know of is 135kg (single) using more carbon and magnesium. You've then got 165kg for an extra cylinder and general beefing and size increases.
Nicely illustrated. ![smile](/inc/images/smile.gif)
In these days where anything under 1,500kg is considered lightweight it's good to restore a little perspective. Still find it hard to believe the usual benchmark for light weight, the S1 Elise, weighs nearly a quarter of a ton more than a road-spec Caterham!
Seriously nice car, more manufacturers should go back to basics with their cars, lightweight ftw!
300 kg should be do-able imo. A 1l sportsbike is ~170kg dry. Heavily tuned examples are only 130-140kg or maybe even less. A standard leisure ATV is 150-220 kg or so. Karts are sub 100 kg. 300 kg for a car is do-able, if you do it the right way.
Numberplates and a roof and I would want something like that as a daily![biggrin](/inc/images/biggrin.gif)

Bit of an odd engine choice for a trackday car I'd have thought ??
my thoughts exactly .http://www.youtube.com/watch?v=X6QDYgLuUI8&fea...
There are a handful of Kit-cars using V-twins because they are cheaper than 4 cylinder bike engines and almost as powerful. So it is doable, not sure there are any advantage though.
300kg is possible.
These guys make a Ducati Desmosedici that weighs 145kg at the kerb with 200+bhp! (the NCR M16)
And there ultimate version of the Ducati Hypermotard weighs 115kg wet at the kerb, yes 115kg. Basically all titanium and carbon.

This is based on a over priced Italian (superbike) of questionable build quality and reliabilty. it seems to me they have chosen the mechanicals looking for exclusivity rather than suitabillty.Surely it would have been better to have used a bike engine from one or the japanese manufacturers imo .
