the lower the car acceleration time, fuel consumption and weight, the better!!!

Using the above formula we can set the Alfa Romeo 4C as the benchmark:
  • Alfa Romeo 4C -> 4.5 x 6.8 + (2.0 x 1020/100) =51.0

At 1195 kg (1120 kg + 75 kg) and doing 4.0 sec from 0 to 62 mph, to equal the fuel-efficiency rate of the Alfa 4C it had to have a fuel consumption of:

[51.0 - (2.0 x 1195/100)] / 4.0 = 6.8 l/100 km


which is exactly the same quoted fuel consumption figure for the Alfa 4C, however with 335 hp (more 95 hp than the 4C) this racing version of the Toyobaru can't possibly match the lighter Alfa 4C quoted fuel consumption figure , therefore the Toyobaru even in this racing version still has a worse fuel-efficiency rate than the Alfa 4C, which is almost impossible to beat without diesel :
