On the Lupo 2l project:
Yes I reached two liter fuel consumption level.
Yes I built very fast car,
Yes got 120 hp and 280 Nm from 1.2 TDI
No I did not reach 0.20 Cd only 0.221
For summer 2014 its time to tune Audi A8 D2:
3 liters at 100 km/h speed= 61,9 MPG us at 62 MPH
Tune that 1.2 TDI to 144 hp and 350 Nm ( Best hp per liter figure in production diesel)
Weigth under 1400 kg, while keeping interior
Cd should be 0.22 to reach those goals
Whats keeping me down is money as I dont have the money for that car at the moment and if I will get it after later next year it will be very tight schedule as Finnish summer is short.
For 2015 it will get some EV help to make it faster than S8 models out there
