Friend showed up in his brand spanking new Mazda 3 5 door today. Shows he got 43 mpg driving up from Austin. Hope he puts a LOT of miles on it going back and forth between Austin and OKC to spend time with his Dad with Alzheimer's.

That Sky Activ thing that Mazda is selling is interesting. It's a 14:1 compression motor but the domed piston has this little pocket at the top. It uses cylinder injection so puts the fuel and spark in that top pocket to keep it from pre-igniting. They also use variable intake timing to put less charge in the cylinder when not under load to effectively lower the compression and increase gas mileage.

When I got the GTS was looking at BoxsterS or Carrera Cabs with PASM. So though the SC has its' charm not really interested in getting in on the bidding war.
