Here's a stupid idea I just had.
What if someone could come up with a vehicle rating formula to rate vehicles
that took different specs into account? Using the following parameters:
MPG or L/100km
LBS/HP or kg/kW
Maybe even price and/or coefficient of drag
Through a formula of multiplying, dividing, etc of these numbers, come up
with a "rating" to describe the vehicle's efficiency/economy. So the
higher/lower the number, the more "efficient" the vehicle is in the real
world and in your wallet.
We all know that more performance = less mileage, but this system could take
into account the amount of performance you are getting for your mileage.
This would decide which vehicle is more "efficient."
Example (Canadian Models, pricing and specs):
Vehicle: 2006 Chevrolet Corvette Z06 Hardtop 1SB
Engine Size: 7.0L
Mileage Highway: 8.2 L/100km
Mileage City: 14.3 L/100km
Power: 377 kW
Weight: 1420 kg
Coefficient of drag: 0.34
Vehicle: 2006 Dodge Viper SRT10 Coupe
Engine Size: 8.3L
Mileage Highway: 11.8 L/100km
Mileage City: 19.6 L/100km
Power: 373 kW
Weight: 1547 kg
Coefficient of drag: 0.39
If you compare the two vehicles' numbers, you can see the Corvette Z06 is
more "efficient." So if you could take all those numbers and mathimatically
turn them into one, it would make for easy comparison. I'd call it the
Mackie Vehicle Rating System. ;) Something like, "the MVRS of the Z06 is 52
and the MVRS of the Viper is 45." Then if you applied the formula to a
Cobalt and got an MVRS of 48, you could say "the Cobolt is more "efficient"
than the Viper, but because of the R&D and technology built into the
Corvette, it is more "efficient" than the Cobalt." Kinda of a "bang for your
See what I'm getting at?
