... though the X is still faster.

Interesting excerpt, confirming that the airflow under the hood is a real limitation:

"The Supercharged Northstar V-8 will also power the upcoming V-Series edition of the XLR luxury roadster slated for production in early-2006. XLR-V is certified at 443 hp at 6,400 rpm and 414 lbs.-ft. of torque at 3900 rpm. The Supercharged Northstar generates more peak power for the STS-V, compared to the XLR-V, due largely to the greater underhood space of the STS that allows more induction and exhaust capacity. On the other hand, the XLR-V will be a quicker car than the STS-V, given its superior power-to-weight ratio."

"The official power ratings for the 2006 STS-V -- 469 hp at 6,400 rpm and 439 lbs.-ft. of torque at 3900 rpm - are certified by the Society of Automotive Engineers (SAE.) "

XLR-V Compared to the SL55

This is in response to some performance questions in another thread having to do with pricing.

The 320hp V/8 XLR is compared to the 302hp V/8 SL500

The 443hp Supercharged V/8 XLR-V is compared to the 497hp V/8 SL55
If you stay tuned you will see that the XLR-V WILL have equal to better performance times for about $30,000.00 less.

The XLR does not have a comparable model to the 12 cyl. SL600 (135,000) or SL65 ($188,000)
