I think you are going to maybe reinvent the old discussion about what is the ideal weight to power ratio for the perfect everyday sports car. I agree with you completely that most supercars' excessive weight/power ratios, result in something completely wasted for normal everyday driving. You may wish to change the ratio from weight/HP to weight/torque power, along with adding some lower gear ratios,... But if you again add more power to weight, you will soon go beyond any practical usability for normal driving.

It sounds like you must love the standard 2.7 Cayman. I drove the 2.7 in city conditions on three different occasions and I thought the car's overall feel, handling, balance and power, relative to normal everyday use, was brilliant... very near perfection.

I suggest that you look for other cars that come up with similar 12-14 LBS/HP ratios.

Cayman 2.7L

2986 LBS/247 HP = 12.08
2900 LBS/201 lbs-ft = 14.42


BMW E30 M3

2866 LBS/192HP = 14.9
(Evo3) 2866 LBS/238 HP= 12.04


Mini Cooper S

2496 LBS/175 HP= 14.26
2496 LBS/200HP = 12.48
