What would you prefer - Maybach Exelero or Cadillac Sixteen?

Both are 139 cm high.

Exelero is 589 cm long. It has 2 doors, and 6 l V12 engine producing 700 horsepower. It weight 2660 kg.

Cadillac Sixteen is just 567 cm long, but in this space go 4 doors, and 13,6 l V16 engine producing 1000 horsepower. The weight is just 2270 kg.

How do the acceleration and maximum speed of Sixteen compare against Exelero, considering Sixteen is lighter, smaller and more powerful?

Oh, and Sixteen also has displacement on demand - it can run on as few as 4 cylinders. What is the fuel burn of Sixteen on a road, at steady 90 km/h?
