A key difference missed above, is the S3 Elise, with the 2ZR-FE supercharged engine, is charge cooled by Lotus, the old 2ZZ version in the Elise wasn't. Power will be a lot more consistent as temps rise.
This is why Lotus pushed a bit further, with minor mods, to offer the Cup 250. Same 2ZR-FE SC CC drivetrain as the standard 220 (all power is measured in PS, not BHP).
For those who miss the S2 Exige S2 240 / 260 power levels, with the small car dynamics, the Elise Cup 250 has effectively taken that place, whereas the Exige V6 feels quite different to drive.
Another key difference is torque. The 2ZR-FE has more torque & lower down than any SC 2ZZ (Lotus OE)
Finally, the gear change on the EC60 is much more precise than the C64 & I've not heard of failures
So although the 2ZZ drivetrain is more 'exotic' than the hum-drum 2ZR-FE, the newer drivetrain still performs OK - thats progress I guess.
Given equal drivers / conditions, I dont feel an Exige Cup 260 (the peak S2 out of the factory) is any faster than an Elise Cup 250... in fact, the Elise Cup 250 might be quicker, as you have better torque to pull out of slower speed corners, less chance of a missed gear change & its easier to place due to better visibility.
