150 kg passenger weight? No. EU weight AT BEST is with single occupant and 90% fuel.vorticism wrote: ↑19 Aug 2022, 15:11Fuel weight anywhere from 75-150 kg, passenger weight 75-150 kg, 5-10 kg for fluids. Which could bring it nearer to the weight posted on wikipedia. Min 1100 kg assuming the rumored starting figure of 1400 kg is a real number. +40% weight increase would be a massive discrepancy on any automotive project and I doubt it could be explained by cost cutting on a carbon tub. Doesn't make sense to me.NoDivergence wrote: ↑19 Aug 2022, 05:03It's an EU registration weight, which includes 90% fuel and I believe one 75 kg occupant, which is why I stated 1320 kg in my post to subtract out occupant. That said, that is quite standard quoted for wet weights. Much higher than what was originally promised.vorticism wrote: ↑18 Aug 2022, 23:52Right but if it's a laptime with caveats then what use does the delta value serve? 3.2g cornering and a +10 top speed delta to DPi is in the ballpark as far as individual metrics go, and you could hit both of those metrics if you wanted to on a 3 minute laptime in between talking to your passenger. Seems unlikely it has an off the shelf LMP2 chassis, the roofline and door openings would be different. The dutchman in your vid stated 1400kg although I can't find this figure anywhere else except some reference to someone running the plates, which implies an MOT inspection which might imply an in situ measurement i.e. presence of fuel or even occupants. Maybe he mispoke?
Interesting article on the finances, btw. It still lacks vehicle metrics though. Only one was mentioned, a single goodwood hill run, not sure which year. Goodwood is a mixed bag times wise. Rally and GT3 cars often post the fastest times year to year, outpacing open wheelers, due to the nature of the course and who's driving and whether or not the vehicle owner is okay with a potential crash. A kei class sized car currently holds the record.
The Valkyrie has a 18.5 gallon tank. At 6 pounds per gallon fuel, that is 110 pounds, or 50 kg give or take if we're generous. Let's say there's another 10 kg of hydraulics and washer fluid, etc.
So 1400-75-50-10 puts dry weight at 1265 kg.
As I stated, hundreds of kg (265 kg) higher than promised to customers putting down deposits, per the linked history I posted. The cost cutting/under designed structures that is rumored is not the tub. It's for every metal component on the car, titanium fasteners, control arms, gearbox, etc etc. Or it just sounded good to a marketing guy. 1000 hp and 1000 kg
The only person who has avoided mass creep for a road car is Gordon Murray.
As far as lap times go for the AMR Pro, there are none that are representative.
But it is telling that their hoped for laptime at LeMans is 3'20. Which I doubt they'll be able to hit based on their development record of these cars.
Oh, and LMP2 cars can corner at 3.5G with theoretical up to 4G at the right speed and corner type.
