May be of interest: With a 180 pound driver, the $51000 2100 lb Exige and the $30000 2900 lb Solstice GXP have about the same power to weight ratio (about 12 pounds per horsepower).
The torque to weight ratio (acceleration) is quite different. The 138 ft-lb Exige has to move 16.5 pounds for every ft-lb. The Solstice has only 11.8 pounds for every ft-lb, and at much lower rpm (max torque of Exige occurs at 6800rpm).
For the same $51000, the Mallett LS2 Solstice (at 3200 lbs), doesn't change the power to weigh ratio from the GXP. The torque, however, is 8.5 lbs / ft-lb.
Power isn't everything. The Exige is still a tremendous track car and an apples to oranges comparison, but interesting nonetheless.

HP per pound is a much better figure to use then torque per pound. A few years ago I ran some eletricrace cars,the torque was phenominal in the low end - talking faster launches in 2nd then 1st gear (I pulled out the stuff for 1st gear two years ago.) Thing is, by 15,000RPM, most of that torque is gone. Torque at the wheels at a given speed would be better, as that factors in gearing. (which HP does to). Neither figure by itself will mean one is better then the other, driving it and seeing what the engine can do is best. This year, my eletric will be doubling power output by changing to a special motor design that hist turbine speeds, I can regear it for more accelration, and there is no torque loss. (upwards of 50,000RPM). I've wired it up and run it, but lack the gears and mounts for my car yet.
That said, I'd prefer a Miata to the solstice. Preferbly a previous generation. I love barebones cars without flashy interiors. Someday I want a pre 85.5 944 again, I love its simple old dash.
Infinite torque at zero RPM = no power!
