Where do you get that it is 100lbs lighter and 40hp more? Last we heard
Randy's car only exists in mid build, and he was estimating
the weight at 1100 lbs (An R500 is 1115 lbs) and is planning on running the same kind of Duratec motor as the R500, so will have the exact same power options as one would have in a Caterham
You can do all the power to weight math you want, but that is not going to tell you how the car puts down the power, how it handles, brakes, responsiveness, gear ratios, final drive ratios, settings, how it communicates etc., not to mention the variables added depending on the course you're driving. The numbers don't tell the whole story. There are plenty of cars out there that sound awesome on paper but are a let down to drive
On such a light front engined car like this, you can have a ton of power, but it doesn't mean you're going to be able to put it to the ground, especially when exiting corners. You might even end up going slower because you lose time spinning the tires or sliding sideways, etc..
Again, neither car is better and personally, I can't wait until Randy gets this car and comes out to play with the rest of us loonies
