According to www.GMInsidenews.com
Another rumor i've heard indicates the same 253hp but with a Supercharged 2.2L Ecotec engine instead. I don't know which they'll go with (i hope turbocharged motor), but it should have around 253hp. Weight and size figures are pretty much the same as the s2000, and now with the 253 horses and redline treatment on the suspension/wheels/tires/brakes, it just might give the current s2000, Z4, etc... a run for their money. I just hope they price it under 28k. Hopefully the same engine will trickle down to the cheaper (less equipped) Pontiac Solstice version as well and we can get the same level of performance for 23k."6 months after the production of the Saturn SKY, GM will introduce a Saturn SKY Redline, which will be powered by a turbocharged 253HP 2.0L Ecotec engine."
