Horsepower to Weight to Cost

While watching too much Top Gear, I decided to do a little number crunching to see what the fastest car I could find--for the money.

The metric I decided on was (horsepower to weight)*(cost), as both numbers are lower-is-better. We'll call this metric "X". Lower X is better, obviously.

Well, here's the list:

10: Porsche Boxter

  • Weight: 2888 pounds
  • Power: 265 HP
  • Weight/HP: 10.90
  • Price: $49,500
  • X: 539,550

9: Bicycle (and me on it)

The lesson here: don't buy a Porsche.
  • Weight: ~200 pounds
  • Power: 0.1 HP
  • Weight/HP: 2000
  • Price: $200
  • X: 400,000

8: Mazda Rx8

  • Weight: 3065 pounds
  • Power: 232 HP
  • Weight/HP: 13.21
  • Price: $26,795
  • X: 353,961

7: Mazda Miata

  • Weight: 2447 pounds
  • Power: 167 HP
  • Weight/HP: 14.65
  • Price: $26,470
  • X: 343,835

6: Dodge Charger

  • Weight: 3834 pounds (auto)
  • Power: 305 HP
  • Weight/HP: 12.57
  • Price: $26,420
  • X: 332,099

5: Mazda Speed3

  • Weight: 3281 pounds
  • Power: 263 HP
  • Weight/HP: 12.47
  • Price: $24,000
  • X: 329,457

4: Kia Forte Coupe

  • Weight: 2844 pounds
  • Power: 173 HP
  • Weight/HP: 16.44
  • Price: $19,350
  • X: 318,114

3: Hyundai Veloster

  • Weight: 2950 pounds
  • Power: 201 HP
  • Weight/HP: 14.44
  • Price: $18,075
  • X: 265,341

2: Ford Mustang GT

  • Weight: 3631 pounds
  • Power: 412 HP
  • Weight/HP: 8.81
  • Price: $29,710
  • X: 261,745
...and the winner is...

1: Ford Mustang v6

  • Weight: 3453 pounds
  • Power: 305 HP
  • Weight/HP: 11.32
  • Price: $22,310
  • X: 252,549

So, the lesson here is that if you pick this particular arbitrary metric, you should totally buy a big, heavy, powerful, cheap American muscle car--but not the really powerful one. That's right, the v6 Mustang is the most horsepower-to-weight-to-money ratio car I checked stats for.

That being said, it does tend to make the otherwise hideous Veloster an interesting entrant. It also speaks highly of Fish's Kia. It does, however, slightly tarnish my fantasy of owning an RX8 or Miata...

  2. Ben made an excellent point: if you really want to go fast for cheap, you don't buy a NEW car.

    And I'm sure having fun with the 2006 Miata I picked up since that chat. :D
